Aspin Defoliators Disturbance in the Crown of the Continent 50km Buffer (2000-2007)

This layer shows aspin defoliators (large aspen torix and forest tent caterpillars) damage in the Crown of the Continent and a 50km buffer.

Delineates outbreaks of the two focal species referred to as aspen defoliators (large aspen torix and forest tent caterpillar). Covers the CCE and 50km into the surrounding area from 2000 to 2007. This layer is a compilation from multiple sources, Bruce spanworm polygons were removed from Alberta data, focal species were extracted from USDA data.This dataset was developed by the Crown Managers Partnership, as part of a transboundary collaborative management initiative for the Crown of the Continent Ecosystem, based on commonly identified management priorities that are relevant at the landscape scale. The CMP is collaborative group of land managers, scientists, and stakeholder in the CCE.
