Abstract:

Ecoregions of the United States of America: Ecoregional planning units are designed as a basis for comprehensive ecosystem planning.

Purpose:

This data set was compiled for The Nature Conservancy's Ecoregional Planning purposes

Supplemental_Information:

Originally based on Bailey, 1994, these boundaries have been extensively modified by TNC's eocregional planning teams. Written justification for each modification is available through The Nature Conservancy's Ecoregional Planning Office.
