This image service depicts a Use Data Layer (UDL) that represents agricultural pesticide uses on crops as used by US EPA's Office of Pesticide Programs (OPP) in endangered species risk assessments. These UDLs represent anywhere specific pesticide uses could be applied based on a pesticide label, and not where pesticides are currently being used. UDLs generated using a number of national data sources including but not limited to United State Department of Agriculture's Cropland Data Layer, United State Geological Survey (USGS) National Landcover Database and National Oceanic & Atmospheric Organization (NOAA) Coastal Change Analysis Program. Updated routinely, this snapshot represents the data currently used by OPP.
The Endangered Species Act (ESA) provides a program for the conservation of threatened and endangered species and the habitats in which they are found. The U.S. Fish and Wildlife Service (USFWS) and the National Marine Fisheries Service of U.S. National Oceanic and Atmospheric Organization (NMFS/NOAA) lead federal implementation of the ESA, though they are supported by other federal agencies, including the U.S. Environmental Protection Agency (US EPA), as part of the Section 7 consultation process. Section 7 of the ESA directs all Federal agencies to conserve endangered and threatened species and to use their authorities to ensure actions do not jeopardized the further existence of threatened and endangered species or adversely modify designated critical habitats. As part of the Section 7 consultation, Federal agencies work with USFWS and NMFS to identify species found within the jurisdiction of the United States that could be affected by actions carried out by the agency.
The US EPA's Office of Pesticide Programs (OPP) is responsible for ensuring that Agency actions under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) are in compliance with ESA. OPP determines if ESA-listed species or their designated critical habitat may be affected by pesticide products. Pesticide products that "may affect" an ESA-listed species or its designated critical habitat may be subject to additional regulation.
Use Data Layers (UDLs) represent the potential pesticide application sites for agricultural and non-agricultural label uses and associated potential off-site impact areas. These UDLs supports the section 7 consultation process in the overlap analysis that identifies species found on or near these potential pesticide use locations. Generated from many different land cover and land use datasets, several methods have been employed to ensure sufficient accuracy and conservatism for decision making. All UDLs include off-site areas. Off-site areas are not directly applied by pesticides but could be impacted following application through spray drift or run-off. These areas are delineated by distance from the closest source use site from any direction. Several raster functions are available to symbolize the UDLs based on different off-site distances of interest. These include:
Use Site: Distances included (in meters)
0: Field or Use Site
Limited Extent: Distances included (in meters)
0: Field or Use Site
30: Directly adjacent / runoff to terrestrial habitats
150: Common limit for spray drift exposure concerns related to species population level effects
Full Extent: Distances included (in meters)
0: Field or Use Site
30: Directly adjacent / runoff to terrestrial habitats
305: Limits of spray drift model for ground application or airblast
792: Limits of spray drift model for aerial applications
1600: Runoff model limit to wetland habitat

All UDLs generated from the USDA's Cropland Data layer represents agricultural pesticide uses. Each UDL is generated from a group of individual crops classes from USDA's Cropland Data Layer. The over 200 cultivated classes are grouped into 15 general classes to reduces the likelihood of errors of omission and commission between similar crop categories to support decision making. In selecting how to group crops from the CDL, EPA referred to the grouping used by the U.S. Geological Survey (Baker and Capel, 2011) and the Generic Endangered Species Task Force (Amos et al., 2010). This information considers environmental factors that influence the location of crops and the error matrices provided by USDA with the original CDL data. By considering these agronomic factors in addition to the error matrices it is possible to improve the accuracy and year-to-year matches for the UDLs while retaining the agronomic similarities important in decision making. In addition to this categorical aggregation the UDLs are temporally aggregated to include 5 years of data from the CDL to account for changes year to year, such as crop rotations. Currently, these UDLs represent data from the 2018-2022 CDL. The agricultural classes were further refined by comparing county level National Agricultural Statistics Service (NASS) 2017 Census of Agriculture (CoA) acreage reports to county level UDL acreages. If a county's UDL acreage for a given class was lower than the NASS acreage, the UDL extent was expanded within Cultivated Layer from the CDL until the UDL's acreage matched or exceeded the NASS CoA. Data not available outside of CONUS. Land cover classes representing each UDL Combined into a single layer.
