New Study of Why People Move Firewood – and Its Relation to EAB Deregulation

We know that people moving firewood long distances is cause for great concern because of the likelihood that tree-killing pests will be transported to new and previously uninfested locations. This concern has been heightened by the USDA APHIS proposal to deregulate the emerald ash borer (EAB). As the principal federal “quarantine pest” transported by firewood, the EAB provides the legal foundation for most federal and state firewood regulations. (Of course, the EAB regulations also govern other articles that could transport wood-boring pests). (See earlier blogs here and here.)

Most forest pest professionals agree that the greatest risks are associated with individuals who transport firewood for recreational camping or summer homes. These people have proven to be the most difficult to regulate and the most likely to not see – or to ignore – messages intended to discourage them from moving firewood. The Nature Conservancy manages the “Don’t Move Firewood” program. It has done polling on messages and impact and concludes that the percentage of U.S. voters who have heard a “don’t move firewood” message remains steady and that those who have heard that message are less likely to transport firewood, especially over distances greater than 50 miles. More details are here

A recently published study by several academics and one forest service scientist reinforces The Conservancy’s earlier conclusion about the importance of outreach efforts as an essential component of programs intended to manage wood-boring pests. On the other hand, the new study points to additional nuances in crafting messages that will be effective in changing people’s behavior.

 

Findings

 

Daigle et al. 2018 (see full citation at the end of the blog) surveyed 272 people who were camping in public (state) or private campgrounds in three New England states in 2013 – four years after each of those states adopted regulations prohibiting out-of-state firewood and began their outreach efforts. Some campers apparently feel a strong connection to the place they are visiting, as shown by the fact that 84% of the 79 campers at private campgrounds had spent two or more nights camping in the same state in the previous year. That emotional connection might provide a motivation that could be activated to persuade those campers to stop transporting firewood (see below).

The authors found that slightly more than 25% of the 272 respondents reported that they often or always brought firewood from home for camping. More discouraging is that they found that people might not comply even when informed about the risks. Instead, compliance depended largely on the individual’s motivation and commitment level rather than knowledge. Worse yet, campers categorized as “highly involved” in the forest pest issue were just as likely to transport firewood from home as were others. Apparently, these non-compliant campers did not fully “connect the dots” between their concerns about forest health and their own actions. See below for Daigle et al.’s suggestions for ways to help people make those connections.

To understand the role of motivation, Daigle et al. tried to assess the strength of each camper’s beliefs about the relationship between tree-killing pests and the transport of firewood by recreational campers.

Overall, 25% of respondents were very highly involved with tree pest issues; another 22% were highly involved. Respondents’ perception of the relationship between damaging tree pests and transport of firewood differed significantly based on their levels of involvement. Respondents with a low level of involvement were less likely to agree with three statements (listed below) that firewood-associated pests pose a serious threat. Campers with very high levels of involvement strongly disagreed with three other statements that either downplayed the threat or portrayed the respondent’s compliance as “useless” as long as others continue to transport firewood.

Perception questions against which respondents’ agreement or disagreement was measured:

  • “There is not much one individual can do about invasive pests brought in by firewood”
  • “I don’t think invasive pests brought in by firewood are very important.”
  • “The threat of invasive pests brought in by firewood is serious.”
  • “As long as other people continue to bring firewood from home, my efforts to prevent invasive pests are useless.”
  • “The invasive forest pest risk from firewood is exaggerated.”
  • “In the long run, things will balance out with invasive pests.”

 

Rationale

Respondents’ most frequent explanations for why they take firewood from home when they go camping were cost, quality, and convenience. The most frequently cited reason for not transporting firewood was that the respondent knew that it was not allowed.

Level of pest awareness:

While nearly all respondents (92%) had heard something about non-native pests killing trees, but 57% could not recall the name of a specific pest in the absence of a prompt. When asked about the emerald ash borer and Asian longhorned beetle, more respondents had heard about the ALB (77% v. 52%). Most said the principal source of information was a state agency.

 

Suggested Actions

Daigle et al. conclude that authorities need to increase citizens’ exposure to outreach materials in order to activate concern and bring about desired actions to curtail risk of pests in firewood.

One clear need is to counter many campers’ belief that their wood is safe so it is okay to transport it regardless of the regulations. Often they based that belief on the fact that their home is not in a designated quarantine zone. Daigle et al. suggested that educational material should try to counter this belief by emphasizing the time lag between a pest’s establishment and its detection.

To help “connect the dots” between campers’ concerns about forest health and the implications of their actions (transporting firewood), survey respondents suggested using more visuals showing the destruction caused by the invasive forest pests, especially in areas they care about – close to home or favorite recreation areas. Daigle et al. thought such pictures would “help the campers with high involvement to trigger activation of attitudes with the association of forest pests and firewood transport.”

Other suggestions for strengthening outreach were to ensure that the message

  • Is novel – that it does not simply reiterate a camper’s initial belief system.
  • Produces agreement by the recipient without generating counterarguments.
  • Is relevant to the audience’s concerns.

They also suggested that campgrounds (public and private) help motivate campers to leave firewood at home by coordinating with local firewood vendors to provide competitively priced firewood at the campground or by including the cost of providing some firewood in the camping fee.

Daigle et al. made two other suggestions that call for stronger actions.

First, they suggested that outreach programs incorporate incentives or rewards to engage people who don’t have a high level of involvement in forest health issues.

Second, they suggested that authorities reinforce the educational message by using “more direct” actions, such as

  • confiscating illegally transported firewood at check stations,
  • issuing warnings about such actions, or
  • administering fines for moving non-compliant firewood.

The authors suggest that state agencies should consider taking these actions – but I see no reason why federal agencies should not also.

Conclusions re APHIS’ Proposal to Deregulate EAB

Daigle et al. conclude that outreach efforts aimed at curtailing movement of firewood need to be continued. They are a critical component of overall management programs targetting non-native tree-killing pests – programs developed through decades of research and trials. The motive is clear: more effectively delaying these pests’ spread provides large benefits to municipalities and homeowners.

These are the same points made by many who opposed APHIS’ proposal to deregulate the emerald ash borer.

In its comments to APHIS, The Nature Conservancy noted that the domestic EAB quarantine had been effective in limiting spread of the pest through two of the most important pathways – firewood and nursery stock. The resulting slower spread had protected three-quarters of the ash range in the United States and bought time to develop mitigation measures.

Further, eliminating the federal quarantine would not only unleash this pathway for long-range movement of EAB but undermine the many federal, state, regional, tribal, private, and non-profit  partners’ efforts to curtail movement of all invasive forest pests in firewood.

Many other commenters, including several state agencies, the National Association of State Foresters and Southern Group of State Foresters called for APHIS to continue leading national efforts to curtail spread of EAB and other pests through careless movement of infested firewood. The Montana Department of Natural Resources and Conservation and NASF specifically urged that APHIS reinstate the National Firewood Task Force (which APHIS led in 2009-2010).

The Don’t Move Firewood program has a more informal blog on this topic, available here.

South African report: Rigorous, Honest, and a Model for U.S. and Others

Density of invasive plants in South Africa

map available here

 

Last month, in my blog about the US Geological Survey’s report on invasive species  I announced release of a report by South Africa on its invasive species management programs – available here.  Because this report is unusual in both its rigor and its honesty, I’m returning to it here. I think it is a model for our country and others.

The report provides the basics. That is, it analyzes pathways of introduction and spread; number, distribution and impact of individual species; species richness and abundance of alien species in defined areas; and the effectiveness of interventions. Of the 775 invasive species identified to date, 556, or about 72%, are listed under some national regulatory program. Terrestrial and freshwater plants number 574 species; terrestrial invertebrates number 107 species. A different set of 107 species, or about 14%, are considered by experts to be having major or severe impacts on biodiversity and/or human wellbeing. The highest numbers of alien species are in the savanna, grassland, Indian Ocean coastal belt, and fynbos biomes. South Africans are particularly focused on the reductions in surface water resulting from plant invasions. Much of the control effort is under the egis of the decades-old “Working for Water” program.

Also, the report has features that are all-too-rare in work of its kind. First is the authors’ focus on rigor – of data sources and interpretation of those data using standardized criteria. Second – and even more important – is their call for analyzing the efficacy of the components of invasive species program. They insist on the need to measure outcomes (that is, results), not just inputs (resources committed) and outputs (“acres treated”, etc.). Inputs are far easier to measure and are, unfortunately, the mainstay of how most U.S. efforts are tracked – if they are tracked at all.

As they note, measure of inputs and outputs are not useful because they provide no guidance on the purpose of the action or treatment or of its effectiveness in achieving that purpose.

(For earlier CISP advocacy of measuring outcomes, visit the National Environmental Coalition on Invasive Species and read the bullet points under “Recommendations for a Comprehensive National Response”.)

The report has been praised by international conservationists, including Piero Genovesi – chair of the IUCN’s Invasive Species Specialist Group. British ecologist Helen Roy says that, to her knowledge, it is “the first comprehensive synthesis of the state of invasive species by any country.”

 

How well are programs working?

The authors’ focus on rigor includes being scrupulously honest in their assessments of current program components. They note deficiencies and disappointments, even when the conclusions might be politically inconvenient. To be fair, all countries struggle to achieve success in managing bioinvasions. And South Africa is, in many ways, a developing country with a myriad of economic and social challenges.

So it is probably not surprising that, for most factors analyzed, the authors say data are insufficient to determine the program’s impact. Where data are adequate, they often show that programs fall short. For example, they conclude that control measures have been effective in reducing populations of established invasive species, usually plants, in some localized areas but not in others. While the situation would arguably have been worse had there been no control, current control efforts have not been effective in preventing the ongoing spread of IAS when viewed at a national scale. Only one of South Africa’s 72 international ports of entry has consistent inspection of incoming air passengers and cargo – and even those inspections are not carried out outside of regular working hours (e.g., nights and weekends).

The authors are even critical of the “Working for Water” program – which is the basis for most control efforts in South Africa and enjoys wide political support. WfW has two goals: providing employment and development opportunities to disadvantaged individuals in rural areas, and managing invasive alien plants. Despite substantial funding, the WfW program has supported control teams that have reached only 2% – 5% of the estimated extent of the most important invasive plants. Furthermore, programs structured to provide employment have not ensured use of the most efficient control strategies.

 

What’s needed in South Africa — and around the world

The authors conclude that South Africa needs new processes to monitor and report on bioinvasions in order to achieve evidence-based policy and management decisions. They call for (1) more research to determine and assess invasive species impacts; (2) better monitoring of the effectiveness of current control measures; and (3) the development of methods to look at the impact of bioinvasions and their management on society as a whole.

The authors say it is important for South Africa to improve its management of invasive species because their impacts are already large and are likely to increase significantly. They note that improving management efficiency will require difficult choices and trade-offs. They recommend a focus on priority pathways, species, and areas. They also stress return on investment.

 

I don’t know how this report has been received in South Africa. I hope government officials, media observers, landowners, political parties, and other stakeholders appreciate the honesty and expertise involved. I hope they take the analyses and recommendations seriously and act on them.

(Preparation of the report was was overseen by a team of editors and contributing authors employed by the South African National Biological Diversity Institute (SANBI) and the DST-NRF Centre of Excellence for Invasion Biology at (C.I.B). Drafts were widely circulated to contributing authors and other stakeholders for comments. An independent review editor will be appointed to assess the review process and recommend any ways to strengthen the process for future reports.)

 

Meanwhile, how do we Americans apply the same rigor to analyzing our own efforts?

APHIS’ Strategic Plan – Focus on Deregulation & Trade Facilitation

APHIS’ headquarters building

USDA APHIS released its Strategic Plan for fiscal years 2019-2023 just after Thanksgiving. The report is 21 pages long. There is no evidence that any stakeholders were asked for input or review.

The Plan has a disappointing – but not surprising – emphasis on deregulation and “customer service”. A second – and more surprising weakness is the lack of attention to plant pests – even those of agriculture, much less natural resources. The emphasis is clearly on animal pests and diseases – including zoonotics.

APHIS’ mission is “To safeguard the health, welfare and value of American agricultural and natural resources.” To accomplish this mission, APHIS has set three goals:

  • Deliver efficient, effective, and responsive programs.
  • Safeguard American agriculture.
  • Facilitate safe U.S. agricultural exports.

Most references to protecting natural resources relate to finding more environmentally sensitive approaches for the program under which APHIS reduces human-wildlife conflicts (e.g., birds being struck by airplanes).

In the Plan, APHIS Administer Kevin Shea writes in his opening message that achieving APHIS’ difficult mission of protecting the health and value of America’s agriculture and natural resources cannot be accomplished by APHIS alone. Instead, the agency must work collaboratively with other government agencies and industry, and consult regularly with partners and stakeholders regarding programs’ effectiveness. Administer Shea also highlights the importance of “delivering our programs and services efficiently, effectively, with integrity, …” The agency promises to modernize information technology, data management, methods of communication with collaborators, exporters and importers, etc., in order to give good return on expenditure of taxpayer resources. APHIS also pledges to make decisions based on science. There are seven references to basing decisions on scientific data.

Fair enough. Such emphases were to be expected from Trump Administration and prefigured by USDA Secretary Sonny Perdue during his nomination hearing, e.g., facilitating exports, supporting better information technology.

However, the Plan refers to “customer service” or “customer experience” 34 times. An additional seven references are made to reducing regulatory burdens. The Plan also speaks of the need to “protect the health, welfare, and value of American agriculture and natural resources. … at a reasonable cost. … Easing regulatory burdens makes it easier to create jobs and promote economic growth.” (Emphasis added.)

Perhaps the recent proposal to deregulate the emerald ash borer is driven in part by the emphasis on minimizing costs to regulated industries and seeking alternative approaches? (Although the deregulation has been under discussion for several years, predating the Trump Administration.)

from APHIS PPQ website

The imbalance in attention to animal versus plant pests and disease is striking. Each of the 14 goals is supported by a number of specific tactics. There are a total of 100 “tactics” under the two goals most directly relevant to preventing or managing pest introductions. These goals are: “Protecting America’s agriculture” and “Promoting U.S. agricultural exports.” Of the 100 tactics, only ten are clearly related to plant pests; 19 are pretty clearly activities that apply to both plant and animal pests and diseases; and five are unclear as to whether they include plant pests as well as animal diseases. Thus, only a third of the tactics apply!

[In making this calculation, I did not include 43 tactics listed under the first goal (“Deliver efficient, effective, and responsive programs”) or three objectives under the goal of “Protecting American agriculture” that apply explicitly to wildlife management, regulating genetically engineered organisms, or ensuring humane treatment of animals.]

Specific examples of such lack of balance include the six examples illustrating the declaration (on p. 4) that “Pest and disease events are more frequent, more complex, and less predictable.” Five of the examples are animal diseases, the sixth is the insect-vectored human disease caused by the Zika virus.

In discussing its efforts to balance its safeguarding efforts against increasing requests for market access by international trading partners, APHIS mentions some activities pertinent to plant as well as animal pest management, e.g., examining disease and pest risks and inserting mitigation strategies into international agreements and interstate movement protocols. However, the only specific action it mentions is helping countries to build capacity to implement the Global Health Security Agenda.

The only reference to forest pests is under one of the 24 tactics associated with Goal 2. Safeguard American agriculture, Objective 2.1: Prevent damaging plant and animal pests and diseases from entering and spreading in the United States to promote plant and animal health. This tactic calls for strengthening the North American perimeter against pest threats from outside the region to prevent introduction of agricultural, forest, and other invasive pests.

Why are Plant Pests slighted?

Perhaps plant-related efforts were left out because they are less “sexy”? Or because they are more distantly linked to human health? The Plan does state that “The tactics in this plan represent only a portion of APHIS activities and by no means embody all the important work APHIS does to fulfill its mission.”

Who knows what was left out?

How will adoption of this strategy affect future efforts to address tree-killing insects and pathogens – both those already present in the country and those yet to be introduced?

Might PPQ Fill in the Gaps?

In 2014 APHIS Plant Protection and Quarantine issued its own strategic plan. This supplementary plan made frequent mentions of safeguarding natural resources. Indeed, the third of the plan’s seven goals stated:                              

Goal 3: Protect forests, urban landscapes, rangelands and other natural resources, as well as private working lands from harmful pests and diseases

Several “tactics” under each goal also directly applied to protecting natural resources. I list them below:

1) Prevent the entry and spread of ag pests and diseases.

  • Coordinate with Canada to implement an effective multi-national system that reduces the threat of tree pests arriving from Asia and other parts of the world (e.g. AGM).

3: Protect forests, urban landscapes, rangelands and other natural resources, as well as private working lands from harmful pests and diseases

  • Maintain EAB regulatory framework to focus on the leading edge of infestations while minimizing impacts on regulated businesses in quarantined areas.
  • Evaluate the effectiveness of biocontrol releases in states and combining both regulatory & outreach activities to address the risks of moving logs, firewood, and nursery stock.
  • Examine detection technologies and partnering with states to determine and apply the most effective strategies to survey & eradicate the Asian longhorned beetle
  • Partnering with federal and state agencies to enact measures such as a public outreach campaign to mitigate the movement of forest pests through firewood.
  1. Ensure the safe trade of ag products, creating export opportunities for U.S. producers
  • play a leadership role in revising ISPM#15
  1. Protect the health of U.S. agricultural resources, including addressing zoonotic disease issues and incidences, by implementing surveillance, preparedness and response, and control programs
  • Strengthen partnerships with Tribal Nations to develop a robust surveillance and early detection system for detecting and reporting invasive species.
  • Work with all stakeholders to coordinate all-hazards agriculture and natural resources response support.
  • Develop science-based programs in collaboration with industry and academia to jointly identify practices that will mitigate pest damage. E.G., SANC program http://sanc.nationalplantboard.org/ [a Systems Approach to Nursery Certification] implemented jointly with the National Plant Board and nursery industry

Dare we hope that PPQ adopts an updated strategic plan that fills in some of the gaps in the overall APHIS plan?
