Description: Depending on their geometric descriptions, anthropogenic disturbances (as identified from 30m resolution landsat imagery at a viewing scale of 1:50,000) are represented by a line or polygon. Linear disturbances include: roads, railways, powerlines, seismic exploration lines, pipelines, dams, air strips and unknown features. This feature class includes linear disturbances (i) identified in 2010 that were also visible in 2015 (ii) identified as new in 2015 (iii) and identified as new in 2020.

Description: Depending on their geometric descriptions, anthropogenic disturbances (as identified from 30m resolution landsat imagery at a viewing scale of 1:50,000) are represented by a line or polygon. Polygonal disturbances include: cut blocks, harvest, agriculture, built-up areas, oil and gas facilities, mines, well sites and unknown features. Included here are polygonal disturbances i) identified in 2010 that were also visible in 2015 ii) identified as new in 2015 iii) obtained from CFS (harvest polygons for 2015-2020) and added prior to digitization and iv) identified as new in 2020.

Name: Boreal Caribou Ranges defined by Federal RS 2012
Display Field: HERD
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: There are 51 boreal caribou ranges defined by individual provinces and territories across Canada. The range boundaries used in the 2008-2010 mapping (Federal RS 2012) were continued for the 2015 and 2020 analysis.
