Neonicotinoid nitroguanidine group insecticide application rates estimated across the western conterminous United States, 2008 to 2014

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2023-02-14T00:00:00Z
These data represents annual estimates of neonicotinoid nitroguanidine group insecticide application rates across the western conterminous United States from 2008 to 2014. This product contains seven raster layers (appearing as separate bands in a multi-band raster). Each band represents one year of the data beginning in 2008. Estimates are generated by pairing crop specific application rates of neonicotinoids with fine scale crop data obtained from the CropScape cropland data layer. Application units are kilograms per hectare. Further details on the methods used to generate this product are described in: Douglas, M.R., Baisley, P., Soba, S., Kammerer, M., Lonsdorf, E.V. and Grozinger, C.M., 2022. Putting pesticides on the map for pollinator research and conservation. Scientific Data, 9(1),1-15. This data layer was originally generated for use in an assessment of environmental stressors on the occupancy of the western bumble bee and supports the pre-listing science for this species under consideration by the U.S. Fish and Wildlife Service. For more information on that assessment see the publication listed in the Larger Works Cited Section.
