This shapefile shows average annual county pesticide use estimates for the five-year period surrounding 2002 in pounds applied of active ingredient for the Oklahoma Tribal Statistical Areas and Reservations (see ds480_tribal_areas shapefile) of Oklahoma.. The pesticides included in this shapefile were selected by U.S. Environmental Protection Agency Region 6 as chemicals of concern for both ground and surface water. County pesticide use was estimated by combining statewide information on pesticide use rates available from the National Center for Food and Agricultural Policy, and county information on harvested crop acreage from the Census of Agriculture (Thelin and Gianessi, 2000). Pesticide use values represent typical use patterns for the five-year period surrounding 2002. These data are not intended for local-scale (county-level) analysis of pesticide use, but rather as a general reference to the variability of pesticide use in the state of Oklahoma. References: Thelin, G.P., and Gianessi, L.P., 2000, Method for estimating pesticide use for county areas of the conterminous United States, U.S. Geological Survey Open-File Report 2000-250, 67p.
This shapefile is to give general reference to the average annual pesticide use in pounds applied for each Oklahoma Tribal Statistical Area and Reservation in Oklahoma. This information should not be used for detailed analysis and studies.

202 NW 66th St., Bldg. 7
County pesticide use estimates in average annual pounds applied data summarized for each Oklahoma Tribal Statistical Area and Reservation and exported as a shapefile. If a Oklahoma Tribal Statistical Area or Reservation part of a county, then the pesticide use estimates for that county was partitioned according to the percentage of that county occurring in the Oklahoma Tribal Statistical Area or Reservation.
