Broadback River Watershed and adjacent area: Interactive Map

(2016-10-20) Global Forest Watch Canada (GFWC) is pleased to release an interactive map of the results of our analyses of Landsat satellite imagery to map anthropogenic (human) disturbance from 1980-2015 in the Broadback River watershed and adjacent area to the south and east. Results show a steady increase in the presence of industrial activities, especially related to the forest industry and the roads required to undertake logging.

Expanding Human Disturbance Footprint in Quebec's Broadback River Watershed

(2016-10-20) Mapping analyses from satellite images shows that the Broadback River watershed, and the boreal forest to the south and east of it, experienced a significant expansion of human development between 1980 and 2015. The analyses, conducted by Global Forest Watch Canada (GFWC), examined the length of linear and area-based disturbances in the Broadback River watershed.

Anthropogenic Disturbance in the Broadback River Watershed, Quebec (1980-2015)

 (2016-10-20) These datasets show the extent of anthropogenic disturbances mapped by GFWC in the Broadback River Watershed region based on Landsat imagery from 1980 to 2015. Three datasets are available for download: (1) linear disturbances; (2) polygonal disturbances; and (3) a dataset in which the linear and polygonal disturbance datasets were buffered by 500m to account for an ecological footprint and combined. The disturbance data in all three datasets is separated into 5-year time periods, from 1980 to 2015.

Bulletin: Time Series Analyses of Anthropogenic Disturbance in the Broadback River Watershed, Quebec

(2016-10-20) This bulletin presents the results of time series analyses of anthropogenic industrial disturbance in the Broadback River watershed in Quebec, as well as an area to the south and east. The results reveal a steady increase in both linear and area-based disturbances. Logging and associated road development are the most significant contributors to the cumulative growth of human impacts; however, there are still opportunities to ensure that further development is minimized in the watershed.

1990-2006 Anthropogenic Changes within the Pascagama Site in Québec's Boreal Forest: Summary of Results

(2007-02-16) The summary results of an up-to-date survey of human disturbances in the Pascagama region of the Boreal region in Québec, which reveals many recent impacts caused by logging and associated roads. The study was undertaken using satellite imagery over the period of 1990 to 2006.

Recent Anthropogenic Changes within the Northern Boreal, Southern Taiga, and Hudson Plains Ecozones of Québec

(2006-02-09) This report, GIS data, maps, etc. share the results of the first stage of our change analysis project. Satellite images from different dates (~1990 and ~2000) for a selected study area in Québec were compared using a differencing algorithm so that we could assess where recent forest disturbances have occurred. The report includes three maps translated into Cree and is available in both English and French!
