The following datasets were published in 1995 on CD-ROM by the USDA Forest
Service and have been superceded by a 2007
version of ecoregions. Users are urged to use the newer version. However,
the 1995 version is provided here in the event that the older version is needed
to recreate analyses conducted using the older definitions. The original 1995
CD-ROM also contained another 65 MB of high resolution TIFF images. Aside from
these images, the contents of the original CD-ROM are all available here.
