Abstract

Equivalent Clearcut Area (ECA) results for Watershed Management Level (WML) 4 sub-watersheds within the Babine Lake Watershed. Prepared by Eclipse Geomatics Ltd. in April 2023 for SkeenaWild Conservation Trust.

This work builds on the 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 eight Watershed Management Levels (WMLs) in the Babine Lake Watershed Atlas Group.
