Summary

This dataset maps all polygonal features in a Broadback River Watershed region based on Landsat imagery up to 2015.

Description

This dataset maps the extent of polygonal features in the greater Broadback River watershed based on Landsat imagery from the 1980 to 2015 time period. This dataset is based on the Environment Canada "Boreal ecosystem anthropogenic disturbance vector data for Canada based on 2008 to 2010 Landsat imagery". This updated dataset follows the same digitizing rules and classes described therein. This dataset, however, has assigned the year the disturbance based on the earliest Landsat image where the disturbance is visible, beginning in 1980 and indicated for 5 year intervals thereafter.

Description
The generation of geospatial thematic information for managing and monitoring Canada's boreal ecosystem is essential for researchers, land managers, and policy makers. Canada's boreal region is a vast mosaic of forests, wetlands, rivers and lakes, but anthropogenic disturbances have impacted these ecosystems resulting in habitat loss, fragmentation and threats to biodiversity. Across Canada various geospatial datasets representing anthropogenic disturbance exist for timber harvesting, hydro-electric activity, settlement and oil & gas activities; however, these products often vary in scale, attributes, time period, and mapping technique. Driven by the need for national data as part of the 2011 boreal caribou science assessment, a standardized methodology was developed and implemented to create a single geospatial dataset representing anthropogenic disturbances across a significant portion of Canada's boreal ecosystem. The boreal ecosystem anthropogenic disturbances BEAD data is a vector disturbance dataset of individual linear and polygonal disturbance types that were manually collected through the interpretation of 2008 to 2010 Landsat imagery at a 1:50,000 viewing scale. Summary results identified a total polygonal anthropogenic disturbance footprint of approximately 24 million ha with forest cutblocks accounting for more than 60 % of mapped polygonal disturbance. Linear disturbance features across the boreal total approximately 600,000 km with roads and seismic exploration lines contributing to more than 80 % of the mapped linear disturbances.
