APHIS Nursery Stock Regulations (Q-37) – Modernization Finally Completed!

After about 20 years, APHIS has finalized important changes to the regulations which govern imports of living plants (what they call “plants for planting”; the regulation is sometimes called “the Quarantine 37” rule).  The new regulation takes effect on April, 18, 2018.

I congratulate APHIS on this important achievement!

[Twenty years is a long time – so changes happen. When APHIS released its Advance Notice of Proposed Rulemaking (ANPR) in December 2004 and its proposed rule in April 2013, I was employed by The Nature Conservancy and submitted comments for that organization. I will refer to those earlier comments in this blog. However, I now represent the Center for Invasive Species Prevention, so my comments here on the final regulations reflect the position of CISP, not the Conservancy.]

APHIS’ 2004 ANPR came after years of preparation. Then, more than eight years passed until the formal proposal was published on April 25, 2013. Comments were accepted from the public until January 30, 2014. During this nine-month period, 17 entities commented, including producers’ organizations, state departments of agriculture, a foreign phytosanitary agency (The Netherlands), private citizens, and The Nature Conservancy. [You can view the ANPR and proposal, comments on these documents, and APHIS’ response here — although you need to click on “Restructuring of Regulations on the Importation of Plants for Planting” and then “Open Docket Folder” to pursue the older documents.]

In the beginning, APHIS had a few goals it hoped to achieve: to allow the agency to respond more quickly to new pest threats, to apply practices that are more effective at detecting pests than visual inspection at points of import, and to shift much of the burden of preventing pest introductions from the importer and APHIS to the exporter.

Progress has been made toward some of these goals outside this rule-making. APHIS instituted a process to temporarily prohibit importation of plants deemed to pose an identifiable risk until a pest risk assessment has been completed (the NAPPRA process). APHIS has further enhanced its ability to act quickly when a pest risk is perceived by relying increasingly on “Federal Orders”.

At the same time, APHIS participated actively in efforts by international phytosanitary professionals to adopt new “standards.” These define a new approach to ensure that plants in international trade are (nearly) pest-free. Both the North American Plant Protection Organization’s regional standard (RSPM#24)  and the International Plant Protection Organization’s global standard (ISPM#36)  envision a system under which countries would no longer rely primarily on inspections at ports-of-entry. Instead, they would negotiate with the supplier or exporting country to develop programs to certify that growers’ pest management programs are effective. Both standards detailed: 1)  how the place of production might manage pest risk and ensure traceability of plants; 2) how the importing and exporting countries might collaborate to administer the program; 3) how audits (including site visits) would ensure the program’s efficacy; and 4) what actions  various parties might take in cases of noncompliance.

It was hoped that these international standards would lead to widespread adoption of “integrated pest management programs” composed of similar requirements – similar to the impact of ISPM#15 for wood packaging.  However, living plants are more complex pest vectors than the wooden boards of crates and pallets, so each country was expected to negotiate its own specific programs – something not  encouraged for wood packaging.

APHIS’ decades-long effort to amend its regulations is warranted because of the high risk of non-native insects and – especially – pathogens being introduced via international trade in living plants. U.S. examples include white pine blister rust, chestnut blight, dogwood anthracnose, and sudden oak death (all described briefly here )

dogwood anthracnose

According to Liebhold et al. 2012 (full reference at end of blog), 12% of incoming plant shipments in 2009 were infested by a quarantine pest. This is an approach rate that is 100 times greater than the 0.1% rate documented for wood packaging (Haack et al. 2014). I have discussed the living plant introductory pathway and efforts up to 2014 to get it under control in my report, Fading Forests III.

 

Shortcomings of the Final Q 37 Rule

So – how well does this final rule  meet APHIS’ objectives?

First, will it shift much of the burden of preventing new pest introductions from the importer and APHIS to the exporter, while ensuring the system’s efficacy? In my view, on behalf of CISP, it falls short.

The new rule sets up a process under which APHIS might require that some types of imported plants be produced and shipped under specified conditions intended to reduce pest risk. However, non-American entities have little incentive to protect America’s natural and agricultural resources and from invasive species. So any new process needs severe penalties for violators.

We have seen how widespread and persistent compliance failures are for wood packaging under ISPM#15. http://nivemnic.us/wood-packaging-again-11-years-after-ispm15-problems-persist/ For this reason, I (on behalf of the Conservancy) had suggested that APHIS formally adopt a specific goal of “no new introductions”. I recognized that this goal was unachievable per se, but suggested that it should stand as a challenge and be the basis for adopting stringent restrictions on plant imports. I suggested  limiting plant imports to those either a) produced under integrated pest management measures systems (verified by third-party certification) or b) plants brought into facilities operating under post-entry quarantine conditions — and following other best management practices that had been developed and supervised by independent, scientifically-based bodies.

In my current view, APHIS’ regulation falls far short of either this goal of shifting burdens or setting a truly stringent requirement. In fact, APHIS has explicitly backed away from its own original goals and procedures.

The new regulation does authorize APHIS to choose to set up import programs under which the exporting country agrees to produce plants for the U.S. market under a system of integrated pest risk management measures (IPRMM) approved by APHIS. In accordance with the international standards, the programs established under this new power will address how the place of production will manage pest risk and ensure traceability of plants; how APHIS and the exporting country will administer the program; how plant brokers will ensure plants remain pest-free while in their custody; how audits will be performed to ensure program efficacy; and what actions various parties will take in cases of noncompliance.

How efficacious this new approach will be in preventing new introductions will depend on how aggressive APHIS is in both choosing the plant taxa and places of-origin to be managed under such IPRMM programs and in negotiating the specific terms of the program with the exporting country.

It is discouraging that APHIS has ratcheted down how frequently it expects to rely on the IPRMM approach. In the explanatory material accompanying the final regulation, APHIS clarifies that did not intend that IPRMM would be used for all imports of living plants. The IPRMM framework is described as only one of several means to achieve the goal of preventing introduction of quarantine pests. APHIS will choose the “least restrictive measures” needed to prevent introduction of quarantine pests. To clarify its position, APHIS changed the introductory text to indicate that IPRMM will be applied when such measures are necessary to mitigate risk – that is, “when the pest risk associated with the importation of a type of plants for planting can only be addressed through use of integrated measures.” [Emphases added]

The final rule is also discouraging in some of its specifics.

  • Whereas the draft regulation specified steps that places of production must take to ensure traceability of the plants they produce, in the final regulation the traceability elements specified in each IPRMM agreement will depend on the nature of the quarantine pests to be managed. Again, APHIS seeks to ensure that its requirements are not unnecessarily restrictive.
  • Although the international standard had specified severe penalties when a grower or broker violated the terms of the IPRMM agreement, APHIS proposed to base the regulatory responses to program failures on existing bilateral agreements with the exporting country. Despite the Conservancy’s plea that APHIS follow ISPM#36 in adopting more specific and severe penalties, APHIS has not done so. The one bright spot is that APHIS may verify the efficacy of any remedial measures imposed by the phytosanitary agency of the exporting country to correct problems at the non-compliant place of production. [Emphasis added]
  • APHIS is relaxing the detailed requirements for state post-entry quarantine agreements – despite the Conservancy’s concern that such agreements’ provisions could be influenced by political pressure and other nonscientific factors.

 

Two Improvements

I am pleased that APHIS has retained requirements applied to plant brokers, despite one commenter’s objections. Brokers handling international shipments of plants grown under an IPRMM program must both handle the plants themselves in ways that prevent infestation during shipment and maintain the integrity of documentation certifying the origin of the plants. A weakness, in my current view, is that APHIS will allow brokers to mix consignments of plants from more than one producer operating under the IPRMM program.  APHIS does warn that if non-compliant (infested) plants are detected at import, all the producers whose plants were in the shipment would be subject to destruction, treatment, or re-export.

A major improvement under the new regulation is that APHIS will now operate under streamlined procedures when it wishes to amend the requirements for importing particular plants (whether a taxon, a “type”, or a country of origin). Until now, APHIS has been able to make such changes only through the cumbersome rulemaking process, Instead, APHIS will now issue a public notice, accept public comments, and then specify the new requirements through amendment of the “Plants for Planting Manual” [  https://www.aphis.usda.gov/import_export/plants/Manuals/ports/downloads/plants_for_planting.pdf ] APHIS estimates that such changes can be finalized four months faster under the new procedure.

 

A Final Caveat

Finally, APHIS needs to be able to measure what effect the new procedures have on preventing pest introductions.  Such measurement depends on a statistically sound monitoring scheme. APHIS has stated in some documents that the current Agriculture Quarantine Inspection Monitoring (AQIM) system doesn’t serve this purpose. APHIS needs to develop a valid monitoring program.

Action on the Threat from Phytophthoras in Restoration Plantings

In July 2016 I blogged about the risk that native plant nurseries in California might spread various Phytophthoras to natural areas through use of infected plants used in restoration plantings.

In response to this threat, the California Oak Mortality Task Force has formed a Phytophthoras in Native Habitats Work Group to protect wildlands and assist the restoration industry in adopting practices to ensure they are producing “clean” plants.

The California Native Plant society (CNPS) adopted a policy to promote propagation practices that help prevent plant diseases. CNPS also established its own Ad Hoc Committee on Phytophthoras to address the same threat.

Numerous resources, including guidelines for nursery management, restoration plantings, summaries of committee meetings, photographs, etc., are posted at this website.

As I described in the July 2016 blog, Phytophthora pathogens have been detected in nurseries in other states, including Maryland, Minnesota, North Carolina, Oregon, and Tennessee. Doubtless nurseries in additional states also harbor damaging pathogens.

I’m not aware of action by regulatory officials, nursery owners, or conservation practitioners in these other states to evaluate and address this threat? Are you?

EU1 Genetic Lineage of Sudden Oak Death Persists in Oregon, Threatens Douglas-fir

In 2015 I blogged about Oregon’s first-ever detection of the EU1 strain of the sudden oak death pathogen – Phytophthora ramorum – in the forest. We know that P. ramorum has four genetic strains. Until this discovery, all P. ramorum infections in North American forests belonged to the NA1 strain.

In response to the 2015 detection, the Oregon Department of Forestry immediately began efforts to eradicate the EU1 infestation. This program was funded in part by the USDA Forest Service Forest Health Protection program and APHIS.

Unfortunately, the EU1 strain persists – and has spread. In 2017, six of ten streams in the state found to harbor P. ramorum contained the EU1 lineage. A total of 119 trees infected  by the EU1 strain grow in five separate sites. Infections on 43 additional trees are still being tested to determine their lineages. Under the Oregon eradication protocols, 371 acres of private and state-owned properties will be affected by management targetting the EU1 lineage.

This news is alarming for two reasons.

First, the EU1 lineage is more aggressive than the more common NA1 strain. For example, the EU1 lineage in Europe kills several types of conifers, including western hemlock (Tsuga heterophylla).  In Oregon, the EU1 strain has been found to infect both Douglas-fir (Pseudotsuga menziesii) and grand fir (Abies grandis)  (LeBoldus et al. 2017). Douglas-fir is, of course, the foundation of the wood products industry in the West.

Second, the EU1 lineage is of the opposite mating type as NA1, creating the potential for sexual reproduction and increased variability in the pathogen population. (Sexual reproduction in P. ramorum can occur only when opposite mating types meet; in the absence if opposite mating types, all reproduction is clonal.)

The Oregon Department of Forestry continues eradication efforts. The program has been completed at one site; efforts at the other four known sites are a priority this year. Funding and resource constraints mean that sites infected by the more widespread NA1 strain are not likely to be treated this year. (ODF has approximately $1,375,000 available for eradication efforts in FY 2017-18.) No mention has been made of whether the USDA Forest Service or APHIS will provide assistance.

COMTF Newsletter March 2018

The EU1 pathogen probably spread to the original infected tree from a small private nursery nearby. That nursery had been reported to be infected with the EU1 lineage of P. ramorum in 2012. As I noted in my earlier blog, this infection confirms fears that contaminated nurseries can spread the pathogen into the forest.

Help Fund Priority Tree-Protection Programs

 

Your help is needed to prevent cuts to vitally important programs that protect America’s forests from non-native insects and pathogens.

  1. USDA APHIS

The USDA Animal and Plant Health Inspection Service (APHIS) is responsible for preventing introductions of new pest that threaten plants – including forest trees —  and for carrying out programs to eradicate or contain those that slip through their safeguards. I have blogged often about the unacceptable level of risk that the agency accepts, which enables new pests to be introduced. For examples, search “international trade” or “invasive species policy” on this site.

To see the President’s budget proposal, download the USDA budget justification here; search for “animal and plant”]

APHIS’ most important programs to counter tree-killing pests are funded through the “tree and wood pest” and “specialty crops” accounts. The former account pays for efforts to eradicate the Asian longhorned beetle (ALB), and to slow the spread of the emerald ash borer (EAB). As part of the latter program, it also funds APHIS’ engagement in regulating movement of firewood from quarantined areas.

For several years, the “tree and wood pest” account has been funded at $54 million. This is not sufficient, but we now face worse. The Administration has proposed cutting funding for the “tree and wood pest” account by more than half (from $54 million to $25 million).  This level of funding would not even maintain the ALB eradication effort!

 

USDA smokejumpers search for ALB

The specialty crop account funds APHIS program to prevent sudden oak death  from being spread via the nursery trade. It is slated for a cut of 18.7%  (from $172 million to $139 million).

The Administration has proposed cuts to other programs that also would undermine protection for forest trees:

  • 24% cut (from $21 million to $16 million) to methods development. This is the program under which APHIS develops new techniques for detecting, monitoring, and controlling pests.
  • 5% cut (from $27 million to $22 million) to funding for pest detection. It is counterproductive to reduce programs to detect pests, since early discovery is crucial to successful eradication.

APHIS funds work on the spotted lanternfly (in Pennsylvania) and the polyphagous and Kuroshio shot hole borers (in California) through Section 10007 of the Farm Bill. The Farm Bill sets a funding limit for each year that is not subject to annual appropriations so these programs are not at immediate risk of being defunded. Also, APHIS can request emergency funding from the Commodity Credit Corporation. In February 2018, APHIS obtained $17.5 million in such emergency funding to support enhanced eradication efforts targetting spotted lanternfly in Pennsylvania. APHIS will continue to rely on Section 10007 funds to address this pest in other states to which it has apparently spread (Virginia, possibly Delaware, Maryland, and New Jersey).

 

 

Please ask your Congressional Representative and Senators to oppose these proposed cuts!

APHIS receives its annual appropriation through the Agriculture Appropriations bill. This legislation is written by the House and Senate Agriculture Appropriations subcommittees.  Members of these subcommittees are listed below. These legislators are especially influential in determining funding for APHIS programs.

  1. USDA Forest Service

The Administration has proposed damaging decreases in both research and management programs that target non-native insects and pathogens.

  1. Research & Development

The research budget proposal contains numerous figures which don’t appear to add up. I have contacted USFS budget officials to learn how to understand these apparent discrepancies. To read the overall USFS budget, go here.

The budget proposes cutting overall research by 14.8% — from $306,216,000 to $260,800,000. According to the table on p. 30 of the budget justification, invasive species research is allocated $28,558,000. The text says this is 17% of the total Research budget – but my calculation is that it is 10.9%. The discrepancy apparently resulted from a failure to adjust to last-minute changes in funding amounts. The invasive species allocation is described as being a decrease of $3,217,000 from the FY18 figure. Despite these cuts, invasive species are described as one of six “strategic program areas”.

The Forest Service provides a table breaking out funding for work by the research stations on more than a dozen individual pest species or groups of species. The table listing this spending (on pp. 45-46) shows a total of $7,591,000 for FY18 and $6,271,000 for FY 19. The $22 million remaining in the “invasive species” program is apparently spent by staff at headquarters or possibly regional offices.  I am trying to find out what this larger category of expenditures includes.

Furthermore, the $6.2 million total includes programs targetting several native species (western bark beetles, southern pine beetle), as well as subterranean termites and invasive plants. If one subtracts expenditures for those species, only $3,091,000 is allocated to non-native tree-killing insects and pathogens in FY18 and $3,252,000 for FY19. This is 1.2% of the overall research budget. Cuts for the individual species range from 19% to 21%.

Since 2010, total funding for research on the ten specified non-native insects and pathogens has fallen by more than 60% — from about $8 million to $3 million. The table listing expenditures on individual species cannot be complete; for example, it does not include efforts to breed pest-resistant elm and beech. Nor does it include recently detected pests, such as spotted lanternfly and polyphagous and Kuroshio shot hole borers – which I hope the Forest Service is studying.

The budget foresees a 42% cut in staff-years from FY18 to FY19 – from 1,469 to 855. USFS Research staffs have been falling for several years (illustrative graph is available in Chapter 6 of Fading Forests III here.) Supportive funds to cover costs of travel, fieldwork, student assistants, and grants to universities have also fallen precipitously, further impeding research efforts.

 

  1. State & Private/ Forest Health Management

The Administration’s proposed budget for the USFS proposes a cut of 8.5% in the program that actually combats damaging pests. The cut to funding for pest-management projects on federal lands is 6.5% ($55,123,000 to $51,495,000). The cut to funding for work on state and private lands (the “cooperative lands” account) is 11% ($38,735,000 to $34,376,000). The budget assumes corresponding cuts to staff by 11% (341 staff-years).

The justification notes that, with this budget, the Service will be able to treat fewer acres, so the agency will “focus on the most pressing needs for forest restoration and reducing communities’ risk to wildfire”.

I consider the ostensible focus to be highly misguided. Even the budget justification concedes that pests and pathogens cause billions of dollars of damage each year and that pest-management methods are more effective when treatments are applied regardless of land ownership. Indeed, history shows that pests enter and first establish in urban and suburban areas that receive the imports that transport pests, like wood packaging or nursery stock. If the USFS fails to help counter pests at these introduction sites, it dooms itself to dealing with well-established invaders – at best an enormous and expensive effort, at worst, failure.

As noted earlier, the table on pp. 45-46 lists spending on individual pest species. The total given is $21,356,000 in FY18; the proposal cuts spending to $19,407,000 in FY19.  As above, I subtract expenditures for native species (western bark beetles, southern pine beetle), subterranean termites, and invasive plants. The resulting subtotals are $12,874,000 for FY18 and $11,681,000 for FY19.  As usual, the gypsy moth receives the bulk of the expenditures — 62% for both years. To meet the lower total mandated for FY19, spending is cut 8 – 9% for each non-native species listed.

In FY10, spending on the 11 named non-native insects and pathogens was $24 million. By FY18, it had fallen by nearly 50% — to $12.8 million. Pest species suffering the largest cuts are the Asian longhorned beetle (zeroed out), hemlock woolly adelgid (52% decrease), oak wilt (27% decrease), sudden oak death (18% decrease), and the combination of goldspotted oak borer, thousand cankers disease, and laurel wilt (15% decrease). The budget justification document does not provide sufficient information to allow me to judge the wisdom of the individual cuts.

It is troubling that the table makes no mention of other invaders – e.g., polyphagous & Kuroshio shot hole borers, spotted lanternfly, velvet longhorned beetle, winter moth (this last is mentioned in the narrative). The first four are relatively new pests with costs that could impose catastrophic damage if they are not countered by adequate programs.

  1. Urban Forestry and International Programs

The budget proposes to eliminate funding for both urban forestry and international programs. I consider both programs important to invasive species management. The former strengthens forestry programs and public support for them in the very places where new pests are most likely to be introduced! The international program supports cooperation with foresters in foreign countries – the sources for potentially invasive insects and pathogens, as well as locales that can provide possible agents for biological control.

Please ask your Congressional Representative and Senators to oppose these proposed cuts!

New study evaluates “candidate pool” from which invasive species might come

Campanula latifolia – one of the species detected as an “emerging” invasive species in the database relied upon by the authors of the study

The authors of a new study note that officials managing invasive species programs rely largely on knowledge of a species’ previous invasion history to predict its level of threat in the geographic area under their responsibility. This approach does not work with the many introduced species that have no history of a previous detected invasion. Hanno Seebens and 49 coauthors – including tree-pest experts Eckehard G. Brockerhoff, Marc Kenis, Andrew M. Liebhold, and Alain Roques — have sought to figure out how great a handicap that lack of data is. See “Global rise in emerging alien species results from increased accessibility of new source.” The study is available for $10 here. Figures, tables, and references are available without charge.

The study used a database of 45,984 first records of establishment of 16,019 species belonging to the following major taxonomic groups: vascular plants, mammals, birds, fishes, insects, crustaceans, mollusks, and other invertebrates.

Last year, many of the same scientists, relying on the same database, found that the rate of new introductions of alien species has risen rapidly since about 1800 – and shows no sign of slowing down. The adoption of national and international biosecurity measures during the 20th century have slowed introductions – but they are not sufficiently effective, especially regarding those plants and animals that are introduced primarily accidentally as stowaways on transport vectors or contaminants of commodities (e.g., algae, insects, crustaceans, mollusks and other invertebrates). The 2017 study found a strong correlation between these “accidental” alien species’ spread and the market value of goods imported into the region of interest. For that study, go here.  I blogged about the findings on 1 March 2017 – here.

In the new 2018 article, the scientists found that even after many centuries of invasions the rate of emerging alien species is still high. Across all taxonomic groups, one out of four detections during 2000 – 2005 was of a species that had not been previously recorded anywhere as alien. Detections of “new” or “emerging” aliens is occurring at an even higher rate for some taxonomic groups. But new detections of insects fit the average – every fourth detection during 2000 – 2005 was of a species not previously recorded outside its native range.

The authors conclude that the continuing high proportion of “emerging” alien species is best explained by the interplay of 1) the incorporation into the pool of potential alien species of species native to regions formerly not accessible to traders; 2) increases in introduction rates due to higher import volumes; and 3) probably rising establishment rates as a consequence of land degradation that facilitates establishment in recipient regions. This process compensates for the decrease of new invaders from historically important source regions – from which potentially invasive species have presumably already taken advantage of pathways and been recorded as introduced somewhere.

emerald ash borer Agrilus planipennis – one of the species in the database of “emerging” invasive species

 

The number of insect species in the database candidate species pool is 20,611 species – an admittedly small fraction of all insects (for example, there are more than 350,000 beetle species worldwide). Twenty-four percent of these insect species have already been established somewhere outside their native ranges. However, the authors note that data gaps – which are larger for some taxonomic groups and geographic regions – mean that the number of actual “first” introductions is probably larger than records indicate, and consequently the estimated size of the candidate species pools may also be higher. Indeed, the paper does not attempt to estimate the actual size of the invasive species “pool” for insects.

The authors analyzed the importance of eight factors – temperature, relative humidity, import values, three land-use categories, number of botanical gardens, and human population size – in explaining the continued high number of “emerging” invaders detected in recent years. While these factors were explanatory for some taxonomic groups, they had a very low predictive value for insects.

For vascular plants, every third record of an introduction in 2000 – 2005 was of an “emerging” alien  species. Interestingly, the number of botanical gardens in a country was a significant predictor for emerging alien vascular plants. However, as the authors of the article point out, reliance on this factor ignores the probable importance of other contributors such as the number of species planted in the receiving country; similarities between source and receiving environments; and introductions by acclimatization societies, European explorers or settlers, and plant hunters.

In any case, lots of previously undetected alien species are detected each year. In this database, 58% of the species had a single record; 86% of all species have no more than two first records in countries on the same continent. The large number of species with only one or two records led the authors to conclude that most species will not spread widely. I question that conclusion because species often require some time to spread to new locations – either local or distant. The authors do admit that they are unable to determine which species have a high potential for spread.

The continued high rate of introduction of new species leads the authors to estimate that between 1% and 16% of all species on Earth – depending on the taxonomic group – qualify as potential invasive alien species. The authors did not attempt to estimate the true candidate pool or percentage of invasive species for insects. For vascular plants, the authors estimated the candidate pool at 47,000 species (out of a total of 368,000 species on Earth), or 13%.

Like its predecessor, this study’s importance arises from its broad perspective – covering the entire globe and a wide range of taxonomic groups. Its major conclusion that invasions will continue on a large scale serves as a warning to all stakeholders. These include officials charged with protecting agriculture and the broader economy, or the natural environment; conservationists; and those engaged in the economic activities that promote invasion.

However, the authors found that the data did not support more specific advice. First, as noted above, they were unable to determine which of the “emerging” invasive species in all taxonomic groups have a high potential to spread.

For those of us focused on invasive species that threaten native plants, data gaps limit the predictive value of the study the most. The database is too scant even to estimate the invasive species “pool” of potential insect pests. Plant pathogens are not included in the analysis.

Act Now: Forest Protection in the 2018 Farm Bill

 

NOW is the time to advocate inclusion of important proposals in the 2018 Farm Bill. It is currently under consideration by the U.S. House of Representatives and Senate. If we miss this round of Farm Bill legislation, there won’t be another opportunity until 2023. Urge your Senators and Representative to support creation of the two grant-based funds described below.

 

What’s the issue?

We know that about 500 species of non-native insects and pathogens that attack native trees and shrubs are established in the United States. The number in Canada is 180 – there is considerable overlap.

Protecting the trees and their ecosystem services requires development and deployment of a set of tools aimed at either reducing the pests’ virulence or strengthening the tree hosts’ resistance or tolerance. Such strategies include biological control targetting the insect or pathogen and breeding trees resistant to the pest. Developing and employing these tools require sustained effort over years.

Unfortunately, the programs now charged with responding to introduced forest pests are only a ragged patchwork of university, state, and federal efforts. They provide neither the appropriate range of expertise nor continuity.  (For a more thorough discussion of the resources needed to restore tree species badly depleted by non-native pests, read Chapter 6 of Fading Forests III, posted here.)

 

CISP-backed Amendments

In order to begin filling the gaps, the Center for Invasive Species has proposed forest-related legislation for the Farm Bill currently being considered by Congress.

We propose creation of two new funds, each to provide grants to support tree-protection and restoration projects. We find that the expertise and facilities needed to plant and maintain young trees in the forest differ enough from those needed to research and test biological approaches to pest management and tree improvement that each deserves its own support.

Our first proposal would create a grant program managed by the National Institute of Food and Agriculture (NIFA) to provide long-term funding for research to restore tree species severely damaged by alien pests. The focus of the research would be on:

  • Biocontrol of pests threatening native tree species;
  • Exploration of genetic manipulation of the pests;
  • Enhancement of host- resistance mechanisms for individual tree species;
  • Development of other strategies for restoration; and
  • Development and dissemination of tools and information based on the research.

Entities eligible for funding under our proposal would include:

  • Agencies of the U.S. government;
  • State cooperative institutions;
  • A university or college with a college of agriculture or wildlife and fisheries; and
  • Non-profit entities recognized under Section 501(c)(3) of the Internal Revenue Code.

Our second proposal would provide long-term funding to support research into and deployment of strategies for restoring pest-decimated tree species in the forest. The source of funds would be the McIntire-Stennis program. The eligible institutions would be similar: schools of forestry; land grant universities; state agricultural and forestry experimental stations; and non-profit non-governmental organizations. Projects would integrate the following components into a forest restoration strategy:

  • Collection and conservation of native tree genetic material;
  • Production of propagules of native trees in numbers large enough for landscape scale restoration;
  • Site preparation of former of native tree habitat;
  • Planting of native tree seedlings; and
  • Post-planting maintenance of native trees.

In addition, competitive grants issued by this second fund would be awarded based on the degree to which the grant application addresses the following criteria:

  • Risk posed to the forests of that state by non-native pests, as measured by such factors as the number of such pests present in the state;
  • The proportion of the state’s forest composed of species vulnerable to non-native pests present in the United States; and
  • The pests’ rate of spread via natural or human-assisted means.

(To request the texts of the proposed amendments, use the “contact us” button.)

 

A Growing Chorus Sees the Same Need

A growing chorus of scientists is calling for long-term funding for forest restoration programs based partly on recent scientific breakthroughs.  So this year’s Farm Bill provides a key opportunity for initiating such programs.

 

The NIFA Letter

The National Institute of Food and Agriculture asks scientists each year to suggest their highest priorities for the agency’s research, extension, or education efforts. In December, twenty-eight scientists replied by calling for setting up a special “division” within NIFA to fund breeding of pest-resistant tree species and associated extension.

The lead authors are Pierluigi (Enrico) Bonello, Ohio State University, and Caterina Villari, University of Georgia. The 26 co-signers are scientists from 12 important research universities, along with the U.S. Forest Service (the Universities of Georgia, California (Berkeley), Florida, Kentucky, Minnesota, and West Virginia; Auburn University; Michigan Technological University; North Carolina State University; Oregon State University; Purdue University; the State University of New York).

The scientists note that recent scientific advances have created a new ability to exploit genetic resistance found in the tree species’ natural populations. They assert that developing and deploying host resistance promises to improve the efficacy of various control strategies – including biocontrol – and provides a foundation for restoring forest health in the face of ever-more non-native forest pests.

The scientists’ proposal differs from CISP’s in calling for establishment of research laboratories and field study sites at several locations in the country. These would be permanently funded to conduct screening and progeny trials, and adequately staffed with permanent cadres of forest tree geneticists and breeders who would collaborate closely with staff and university pathologists and entomologists. The apparent model is the USDA Forest Service’ Dorena Genetic Resource Center  in Oregon. Dorena has had notable success with breeding Port-Orford cedar and several white pine species that are tolerant of the pathogens that threaten them.

 

POC trials at Dorena

In contrast, the CISP proposal relies largely on the chestnut model, which relies more on non-governmental organizations and wide-ranging collaboration. Our overall goal is similar, though: to provide stable funding for the decades-long programs needed to restore forest tree species.

Why do we advocate grant programs instead of establishment of permanent facilities? We thought that Congress would be more likely to accept a smaller and cheaper set of grant programs in the beginning. Once the value of the long-term strategies is demonstrated more widely, supporters would have greater success in lobbying for creation of the permanent facilities.

Among the new technologies that would seem to justify the scientists’ assertion that success in breeding now appears to be more likely is the use of FT-IR and Raman spectroscopy and associated analysis of tree chemicals to identify individual trees within natural populations that have an apparent ability to tolerate disease-causing organisms. The leading scientist on the NIFA letter, Enrico Bonello, has used the technique to identify coast live oaks resistant to Phytopthora ramorum (the causal agent of sudden oak death. He is now testing whether the technique can identify Port-Orford cedar trees tolerant of the root-rot fungus Phytophthora lateralis and whitebark pines resistant to white pine blister rust.

I blogged about Enrico’s work on ash resistance to EAB here.) You can learn more about Enrico’s interesting work here.

The NAS Study

Meanwhile, the National Academies of Sciences, Engineering, and Medicine has launched a study on The Potential for Biotechnology to Address Forest Health. By the end of 2018, a committee of experts will report on the potential use of biotechnology to mitigate threats to forest tree health; identify the ecological, ethical, and social implications of deploying biotechnology in forests, and develop a research agenda to address knowledge gaps about its application. Funding for the study has been provided by The U.S. Endowment for Forestry and Communities; several agencies within the U.S. Department of Agriculture – Animal and Plant Health Inspection Service, U.S. Forest Service, National Institute of Food and Agriculture, Agricultural Research Service; and U.S. Environmental Protection Agency.

The Committee meetings are webcast, and there are other webinars on pertinent topics. You can view the schedule and sign up to receive alerts here.

Several people actively engaged in finding answers to invasive pest challenges have presented their views to the Committee, including Gary Lovett, Deb McCullough, Richard Sniezko, and me (!). You can find our presentations (Powerpoints and oral) at the above website. My talk focused on the crisis posed by non-native insects and pathogens and the need to evaluate the full range of possible response strategies for each host-pest situation. Application of genetic engineering technologies – in the absence of adequate resources for research and deployment of resistant hosts – cannot result in restoration of the host trees.

 

Background Information

Examples of tree-killing pests include such famous examples as chestnut blight and Dutch elm disease as well as less-well-known pests as soapberry borer. This map

indicates how many of the most damaging pests are established in each county of the 49 conterminous states. Descriptions of some of these insects and pathogens are provided here.

Additional tree-killing pests not included in the sources for the data supporting the map for various reasons would add to the numbers of pests in some states. Some non-native organisms have been introduced too recently, others attack palms or trees in Hawai`i; still others are native to Mexico and parts of the United States so were not included.

You Might Be Surprised By Who is Authorized to Manage Wildlife on Federal Lands

The journal Environmental Law has just published a 135-page article that debunks a common myth of wildlife management – a piece that the U.S. Forest Service tried to quash. The authors’ analysis could affect the introduction of potentially invasive non-native species – and the reintroduction of native ones – on federal lands.

Nie, M., C. Barns, J. Haber, J. Joly, K. Pitt & S. Zellmer. 2017. Fish and Wildlife Management on Federal Lands; debunking state supremacy. Environmental Law, Vol. 47, no. 4 (2017).

The article reviews the legal authority of federal and state governments to manage wildlife on federal lands.  The authors examined wildlife-related provisions within the National Park System, National Wildlife Refuge System, National Forest System, Bureau of Land Management, the special case of Alaska, the National Wilderness Preservation System, and the Endangered Species Act. They also reviewed cases where federal and state agencies came into conflict over wildlife management on federal lands.

Citing the U.S. Constitution, federal land laws, and relevant case law, the authors assert that federal agencies have an obligation, not just the discretion, to manage and conserve fish and wildlife on lands and waters under their management. They say that the often-cited statement that “the states manage wildlife and federal land agencies only manage wildlife habitat” is wrong from a legal standpoint. This is the myth that the article debunks.

Furthermore, the authors find that federal agencies frequently apply their powers in an inconsistent and sometimes even unlawful fashion. Due to political pressures, they may back down when confronted by states wanting to manage wildlife to achieve their own goals – even when the state’s goals conflict with the legally-mandated purposes of the federal land under question. Such goals might include ensuring maximum populations of “game” animals or introduction of species to new habitats – regardless of the potential impact on native plants and animals.

The authors note that federal land and wildlife laws provide ample opportunities for constructive intergovernmental cooperation in wildlife management. They call for truly mutual collaboration by federal, state, and tribal authorities in managing wildlife. However, such cooperation is blocked in part by states choosing to challenge the constitutional powers, federal land laws, and U.S. government supremacy. In addition, the authors contend, most states have not put together programs that address their own conservation obligations. These obligations are inherent in the widely recognized doctrine of wildlife being a public trust to be managed for the present and future benefit of the people, not the government or private individuals.

According to the website of the Forest Service Employees for Environmental Ethics,  posting of a draft of this article on the University of Montana website (where lead author Martin Nie teaches) led the U.S. Forest Service to pressure the university to withdraw the article. The university refused, and the Forest Service ended its contract with Nie and his research center.

“Invasive Species Denialism” Increases Exponentially

 

Anthony Ricciardi and Rachael Ryan have analyzed 77 articles published from 1994 to 2016 in scholarly journals and the mainstream media that express some level of “invasive species denialism”. Denialist articles appearing in these publications have increased exponentially over the past three decades, most notably in the mainstream popular press – and they have the graph, fitted to a curve, to prove it.

The authors cite Diethelm and McKee (2009) in defining “science denialism” as “the use of rhetorical arguments to give the appearance of legitimate debate where there is none, with the ultimate goal of casting doubt on scientific consensus.” Similar strategies have appeared in disputes over the dangers of tobacco smoking and climate change.

Ricciardi and Ryan say that “[u]nlike normal scientific debates, which are evidence based, this discourse typically uses rhetorical arguments to disregard, misrepresent or reject evidence in attempt to cast doubt on the scientific consensus that species introductions pose significant risks to biological diversity and ecosystems….” In their view, the “denialist” articles assert an absence of damage from bioinvasion “despite peer-reviewed research that shows otherwise ….”  One example of evidence ignored by the contrarians are several analyses of the causes of endangerment or extinction of vertebrate species listed on the Red List maintained by the IUCN [as reported in my blog from May 2016 link]

Furthermore, these claims are almost always made in the absence of peer review – either in popular media or as opinion articles in scholarly journals. Many of the writers are social scientists and philosophers, not natural scientists. Only five of the 77 articles, or 6%, were published in natural science journals.

Ricciardi and Ryan say that unlike genuine scientific debate, “denialists” reject scientific evidence while repeating claims that have already been refuted in the scientific arena. Often, “contrarians” link invasion biology to xenophobia and latent racism, or otherwise impugn the motives of those engaged in the invasion biology field.

Ricciardi and Ryan consider possible reasons for the rise in “denialist” articles. Possible reasons include anti-regulatory ideologies, distrust of scientific institutions, conflicting values and perceptions of nature, even individuals’ desire for attention. They note that despite the absence of a true scientific controversy, the “denialists’” assertions gain credibility because science reporters think they need to present “both sides” of the argument.

Unlike the situation in the contrived controversies over climate change and risks from tobacco, we at CISP have not found a powerful industry backing the contrarians.

Ricciardi and Ryan express concern that the growing number of articles rejecting decades of research on invasive species might undermine policy initiatives at a time when invasion biology’s relevance to biosecurity, conservation, and ecosystem management is increasing. Gaining public support is critical to the success of such policies.

This concern is especially well-founded given that the authors’ results underestimate the extent of invasive species denialism. That is, they omitted from their analysis articles from internet blogs – known to be major platforms for promoting “science denialisms” – and websites that specifically attack invasion biology.

While Ricciardi and Ryan published this as a “note,” it is packed with information, e.g., references on science denialism, in general; and, in supplementary information, a table citing the 77 denialist articles.

What Is USDA Waiting For?

 

As I wrote in my blog in October, the Department of Homeland Security Bureau of Customs and Border Protection (CBP) has reversed a previous policy and now has the option to impose a financial penalty on importers when any of their shipments does not comply with the international standard for wood packaging (International Standard for Phytosanitary Measure Number 15 – or ISPM#15). The penalties are assessed under Custom’s authority per Title 19 United States Code (USC) § 1595a(b) or 19 USC § 1592.

The Department of Agriculture has its own legal authority to penalize shippers whose wood packaging violates regulations implementing ISPM#15.  However, USDA not taken the equivalent step of using its own authority to crack down on violators. Why not?

APHIS’ legal authority stems from the Plant Protection Act of 2000 [7 U.S.C. §7701, et seq. (2000)] (The text is posted here)

This law provides broad authority to APHIS to penalize non-compliant importers, using both civil and criminal penalties. Under Section 7734 (b):

“Any person that violates this chapter … may, after notice and opportunity for a hearing on the record, be assessed a civil penalty by the Secretary…” The penalty can vary from $50,000 to $1 million, depending on whether the importer is an individual or a corporation; the number of violations adjudicated in the proceeding; the gravity of the violation; and the importer’s ability to pay. Civil penalties can be assessed regardless of whether the violation was intentional (in the language of the statute, “willful”).

Under Section 7734(a), the Department may seek criminal penalties in cases when the importer “knowingly” violated the law and its implementing regulations. Criminal penalties include both fines and imprisonment. To apply a criminal penalty, USDA must convict the importer in a trial – prove the violation beyond a reasonable doubt.

 

It is puzzling that USDA has not acted on this authority.

As we all know, the biological diversity of America’s forests’ is severely threatened by wood-borers that can enter the country in wood packaging. Tree mortality caused by non-native pests has been estimated to cost municipalities $1.7 billion per year (Aukema et al. 2011). For discussions of introduced pests’ impacts, see the sources listed at the end of this blog.

Nearly 12 years after APHIS adopted regulations implementing the formal International Standard for wood packaging, significant numbers of shipments that do not comply with the regulations continue to arrive. In the fiscal year that ended on September 30, Customs detected 2,000 shipments in which the wood packaging did not bear the mark certifying that the wood had been treated in accordance with ISPM#15. In nearly 900 additional shipments, CBP detected damaging pests in the wood packaging. (For more detail on this issue, see my blog from last February.) link. So, the need to improve compliance is manifest. Imposing a financial penalty strikes me as an available and useful strategy to achieve that improvement.

The new CBP policy is a much-needed step. Now USDA should reinforce that action by implementing its own enforcement powers. The USDA’s Office of General Counsel and APHIS should be asked what is preventing implementation and what can be done to move this forward. Effective action to interdict forest pests requires strong enforcement by both CBP and USDA. Right now, it looks like the Department of Homeland Security cares about U.S. forests more than the Department of Agriculture.

New “Plant Pest” Boss Soon to Take Office

Gregory Ibach

 

Gregory Ibach has been appointed USDA Under Secretary of Agriculture for Marketing and Regulatory Programs. He will supervise APHIS.

Mr. Ibach has strong ties to mainstream agriculture. A fourth-generation farmer (cow-calf and rowcrops), he has served as Nebraska’s Commissioner – or Deputy – of Agriculture under three governors – since 1999. His academic background is animal science and agricultural economics.

Mr. Ibach’s nomination was supported by 60 organizations, including the Farm Bureau, National Cattlemen’s Beef Association, and National Corn Growers.

The Senate Committee on Agriculture, Nutrition & Forestry held a very friendly hearing on Mr. Ibach’s appointment on October 5, 2017 2017 (video posted at the Committee website)  During the hearing – which was shortened by the need to attend to other Senate business – Senators’ attention focused on the farm conservation programs managed by the other nominee at the hearing (William Northey, nominee for Undersecretary for Farm and Foreign Agricultural Services). In response to several questions about marketing programs, Mr. Ibach said he needed to learn more about an issue.

In his formal testimony, Mr. Ibach noted the breadth of responsibilities under the jurisdiction of the Under Secretary for Marketing and Regulatory Programs and promised to find a balance between the two duties: representing and promoting the interests of farmers and ranchers; and overseeing some of the entities that regulate them. (Written testimony posted on Committee website — link above.)

“If confirmed, I will help the Secretary achieve his goals through ensuring sensible and effective regulations, responding to our customers in a timely and straight forward manner, focusing on plant and animal health program effectiveness, and fostering safe innovation that is farmer, consumer and environmentally sound.”

I summarize key points of the hearing below.

Committee Chairman Pat Roberts (R-KS) noted that foreign animal disease threats – such as avian influenza – have threatened agricultural production and asked what Mr. Ibach’s priorities would be for safeguarding animal health. Mr. Ibach said he takes very seriously APHIS’ responsibilities to keep diseases and pests out of the country and to control those that enter. He promised to learn about every program.

Ranking Democrat Debbie Stabenow (D-MI) asked Mr. Ibach about budgetary pressures. He responded by saying he would commit to doing the best job possible with available funds and to pursue efficiencies.

Amy Klobuchar (D-MN) was also concerned about disease threats to Minnesota’s large-scale turkey and hog producers.

John Hoeven (R-ND) pressed Mr. Ibach to find a solution to blackbirds as a threat to agriculture. Mr. Ibach said they are a problem in Nebraska, too. He promised to seek a “balanced” approach that preserved wildlife “when appropriate” while protecting farmers from destruction and disease threats.

Senator Leahy (D-VT) submitted questions pertinent to our concerns about tree-killing pests. Noting that Mr. Ibach had spoken about the pest threat to farmers, ranchers, and producers but had made no mention of the forest pests, Senator Leahy asked:

  • What familiarity do you have with APHIS’ work to keep out invasive forests pests that threaten our nation’s forests and the rural jobs and economy those forests support?

Mr. Ibach replied: I am familiar with the work that APHIS does in partnership with states to keep out and eradicate forest pests. In fact, in Nebraska, we have been working closely with APHIS prior to and since Emerald Ash Borer was found in the state for the first-time last year. These pests can absolutely devastate our forests, and if confirmed, I would work to make sure that APHIS’ pest programs, including those to protect the green mountains of Vermont, are effective.

  • Can you tell me how many wood and tree pests APHIS inspectors find every year, which theoretically should not have made it to our shores if importers were using the best available processes and phytosanitary practices to keep American agriculture and natural resources safe? And do you commit to looking into this issue and finding ways to safeguard both American agriculture and our natural resources?

Mr. Ibach replied: I do not have that data, but commit to learning more and working every day to protect American agriculture and natural resources if confirmed.

Senator Roberts said that the Committee would act soon to approve the nominations of Gregory Ibach and William Northey.

 

The Under Secretary for Marketing and Regulatory Programs sets the tone for APHIS’ efforts.  This person can prompt aggressive protection efforts … or block such efforts by opposition or indifference.  Let’s hope that Mr. Ibach plays the former role!
