HEP is used to quantify the impacts of development, protection, and restoration on terrestrial and aquatic habitats by assessing changes, both negative and positive, in habitat quality and quantity .

BPA works directly with project proponents including state and federal natural resource agencies, tribes, and non-government organizations (NGOs) to conduct HEP surveys and develop new, innovative approaches to assess habitat.

HEP documents change through use of a habitat suitability index (HSI). The HSI value is derived from an evaluation of key habitat components and the life requisites of selected wildlife and fish species.
