FY23 House Agricultural Testimony for APHIS

Public Witness Testimony re:
Animal and Plant Health Inspection Service

The undersigned organizations urge continued support by the Subcommittee on Agriculture and Rural  Development for a federal program that is key to protecting America’s urban and rural forests from  pest-caused mortality and associated threat to sustainability in the face of climate change: the USDA  Animal and Plant Health Inspection Service (APHIS). APHIS is responsible for preventing  introduction and spread of invasive pests. While most port inspections are carried out by the  Department of Homeland Security Bureau of Customs and Border Protection, APHIS sets the policy  guidance. APHIS also inspects imports of living plants.

Four USDA APHIS programs are essential for protecting the nation’s forests from invasive pests: Tree  and Wood Pests, Specialty Crops, Methods Development, and Pest Detection. We thank you for the  incremental increases in funding for these programs in the FY22 Continuing Resolution. We also  welcome additional increases proposed by the Administration. However, we suggest that a more  substantial investment is warranted.

Introduced pests threaten many forest products and services benefitting all Americans, including wood  products, wildlife habitat, carbon sequestration, clean water and air, storm water management, lower  energy costs, improved health, aesthetic enjoyment, and related jobs. These pests also impose  significant costs, borne principally by municipal governments and homeowners. As more pests have  been accidentally introduced over time, these costs have risen.

A recently published article (Hudgins, Koch, Ambrose, and Leung. 2022. Hotspots of pest-induced  US urban tree death, 2020–2050. Journal of Applied Ecology), cited in the Washington Post, projects  that by 2050 1.4 million street trees in urban areas and communities will be killed by introduced insect 

pests. Removing and replacing these trees is projected to cost cities $30 million per year. Additional  urban trees – in parks, other plantings, on homeowners’ properties, and in urban woodlands – are also  expected to die.  

Municipalities on the forefront include Milwaukee and Madison Wisconsin; the Chicago area;  Cleveland; and Baltimore, Towson, and Salisbury, Maryland.  

Tree-killing pests are linked to the international supply chain. Many pests—especially the highly  damaging wood-borers like emerald ash borer, Asian longhorned beetle, polyphagous and Kuroshio  shot hole borers—arrive in inadequately treated crates, pallets, and other forms of packaging made of  wood. Other pests—especially plant diseases like sudden oak death and sap sucking insects like  hemlock woolly adelgid—come on imported plants. Some pests take shelter, or lay their eggs, in or on  virtually any exposed hard surface, such as steel or decorative stone.  

Imports from Asia have historically transported the most damaging pests. It is unfortunate, then, that  imports from Asia have reached unprecedented volume. As of February 2022, U.S. imports from Asia  were running at a rate of 20 million shipping containers per year. One analysis indicates that perhaps  7,500 of these containers are carrying a tree-killing pest. These facts have led scientists to project that  by 2050, the number of non-native wood-boring insects established in the United States could triple.  Most damaging would be the hypothetical introduction from Asia of a theoretical wood-boring insect  that attacks maples or oaks. Such a pest could kill 6.1 million trees and cost American cities $4.9  billion over 30 years. The risk would be highest if this pest were introduced to the South – and current  trade data show that U.S. southern ports are receiving more direct shipments from Asia. 

Once introduced, invasive pests do not stay in the cities where they first arrived. Instead, they  proliferate and spread. They are often accidentally transported to new areas in firewood, on plants, and  on outdoor household goods such as patio furniture.  

In this way, the pests introduced to our cities threaten not just the trees in city parks, along our streets,  and in people’s yards, but also the natural forest stands across the country. Scientists estimate these  pests threaten 41% of forest tree biomass across the contiguous United States. Death of these trees will  significantly impair nature-based solutions to climate change.  

To respond effectively to these pests and to the others that will be introduced in coming years, the key  APHIS programs identified above must have adequate funds. For this reason, we thank the Congress  for increasing funding for APHIS’ Tree and Wood Pests program to $61.2 million in FY2022 and ask  that you raise that funding level to $70 million in FY2023.

The Tree and Wood Pests account supports eradication and control efforts targeting principally the  Asian longhorned beetle (ALB) and spongy (formerly gypsy) moth. Eradicating the ALB normally  receives about two-thirds of the funds. The programs in Massachusetts, New York, Ohio, and South  Carolina must continue until eradication succeeds.  

APHIS terminated its domestic emerald ash borer (EAB) regulatory program in January 2021. It is  probable that, in the absence of a federal domestic regulation, EAB will now spread more rapidly to  the mountain and Pacific Coast states. Indeed, the research cited above identified Seattle and Takoma 

as likely to lose thousands of ash trees in coming decades. This result shows what happens when  APHIS programs are inadequately funded. 

APHIS manages damaging pests introduced on imported plants or other items through its Specialty  Crops program. Examples include sudden oak death (SOD; which attacks more than 100 species of  trees and shrubs, including oaks and rhododendrons); the rapid ʻōhiʻa death pathogen that threatens  Hawai`i’s most widespread tree, ʻōhiʻa lehua; beech leaf disease, a newly discovered threat that is  

killing beech trees in a band stretching from Ohio to Maine; and the spotted lanternfly. Repeatedly,  SOD-infected plants have been shipped from nurseries in the Pacific Coast states to vulnerable states  across the East and South. The spotted lanternfly has spread from Pennsylvania to Maryland,  Delaware, New Jersey, Virginia, West Virginia, Ohio, even Indiana. This pest threatens both native  trees and agricultural crops – including hops, grapes, apples, and more. California has adopted a state  quarantine in hopes of preventing its introduction to that state. Still, APHIS has not established a  quarantine. We support the Administration’s request for $219 million for the Specialty Crops program. However, we ask that the Committee ensure that APHIS allots adequate funding under this budget line  to management of both sudden oak death and spotted lanternfly. 

We support increased funding for two additional programs that are the foundation for effective pest  prevention. First, the Pest Detection program is key to the prompt detection of newly introduced pests  that is critical to successful pest eradication or containment. Second, the “Methods Development”  program enables APHIS to improve development of essential detection and eradication tools.  

Finally, we support the Administration’s request for a $50.794 million fund for management of  emergencies threatening America’s agricultural and natural resources. We are encouraged that this  program includes a $6 million increase for work with the Climate Conservation Corps specifically  targetting invasive species. The program will improve surveillance methods to more quickly detect  incursions and develop better methods to mitigate the impacts of invasive species already causing  economic and environmental damage. We look forward to learning more about how these funds are  utilized. We certainly hope that they will not be allocated disproportionately to addressing animal  diseases and pests. 

Thank you for your attention to these important matters. We look forward to working with you.
