DescriptionAbstract
This data set portrays the occurrence of butterflies in counties in New York State. Butterfly occurrence data are cumulative, so positive occurrence data do not necessarily imply current residence of the species. Most records are from the last 30 to 40 years, with a few records that date from as early as the late 1800's.
Purpose
These data are intended for use in publications at a scale of 1:2,000,000 or smaller. Due to the small scale, the primary use is for regional and national data display and analysis, rather than specific local data analysis. No responsibility is assumed by the U.S. Geological Survey in the use of these data.
Supplemental Information
This data set must be used together with the dBASE IV file bflyspt.dbf. Bflyspt.dbf describes the butterfly species to which this occurrence data applies. To create maps that are similar to the maps in the National Atlas <http://nationalatlas.gov/natlas/natlasstart.asp>, butflyt.dbf can be joined to the 2000 county boundaries available from the National Atlas download page, <http://nationalatlas.gov/atlasftp.html>.
