Ecological Integrity Assessment (EIA)

Ecological Integrity Assessment (EIA) framework forms the basis of CNHP’s Level 2 Rapid Assessment protocol. The EIA Framework was developed by NatureServe and ecologist from several Natural Heritage Programs across the country. Colorado-specific EIA protocols have been developed and refined by CNHP with funding from EPA Region 8 and Colorado Parks and Wildlife. The EIA method is an ecologically based condition assessment method that focuses on the biological response to disturbance, but also evaluates underlying processes.

The EIA framework evaluates wetland condition using on a multi-metric index based on three major factors. Each factor has associated metrics, which are scored based on quantitative or qualitative criteria.

  • Landscape Context (landscape, buffer)
  • Condition (vegetation, hydrology, soil, water quality)
  • Size
