Terrestrial Ecosystem-Based Core Area Selection Index
This dataset represents the selection index used to create terrestrial ecosystem-based cores. The selection index is a continuous surface in which every cell is assigned a value (0-1) based on its relative ecological integrity and/or biodiversity value within each HUC6 watershed. Specifically, for all terrestrial and wetland cells, the selection index is a composite index derived from a weighted combination of the 1) weighted index of ecological integrity, 2) TNC's terrestrial resiliency index, and a binary representation of 3) TNC's tier 1 floodplains and 4) S1-S3 rare natural communities as defined and mapped by the state Natural Heritage programs. For aquatic cells (which are also included in this layer), the index is equal to IEI, except in headwater creeks where IEIis averaged with USGS's stream temperature tolerance index
