Acronyms & Definitions

PPL - Project Priority List

Project Area - The benefitted area as determined by the Environmental Work Group for purposes of conducting Wetland Value Assessments

AAHU - Average Annual Habitat Units as determined by the Environmental Work Group. Habitat Units represent a numerical combination of habitat quality (Habitat Suitability Index) and habitat quantity (acres) within a given area at a given point in time. Average Annual Habitat Units represent the average number of Habitat Units within any given year over the project life for a given area.

ACR - Acres Created/Restored represent the acres of emergent marsh created or restored as a result of project implementation.

AP - Acres Protected represent the acres of emergent marsh protected from loss as a result of project implementation.
