Protection Status of Ecological Systems by Ecoregion


This provisional Biogeographic Analysis Package provides an analysis of protection status for ecological systems within Omernik Level III Ecoregions. The ecological system classification defines groups of plant communities that tend to co-occur within landscapes with similar ecological processes, substrates, and/or environmental gradients and is the primary map class used in the Gap Analysis Program (GAP) land cover layer (based on 2001 satellite imagery). This package can be used to identify the ecoregions where ecological systems have the greatest representation in GAP Status 1 and 2 lands (lands managed for the protection of biodiversity) and the ecoregions where ecological systems are the least protected. One important use [...]
