Equivalent Clearcut Area (ECA) results for Watershed Management Level (WML) 5 sub-watersheds within the Babine River Watershed. Prepared by Eclipse Geomatics Ltd. in October 2022 for SkeenaWild Conservation Trust.

This work builds on the Level 1 Peak-Flow-Sensitivity (PFS) assessment work completed by Lake Babine Nation, BC Ministry of Forests, Lands and Natural Resource Operations and Rural Development, Northern Habitat Solutions, and SKR Consultants Ltd. in 2020, which computed PFS scores and ECA risk categories for Watershed Management Areas (WMAs) at six Watershed Management Levels (WMLs) in the Babine River Watershed Atlas Group.
