The previous version of the intact forest landscape data set was based primarily on the visual interpretation of 1988-2002 Landsat images, and some imagery from the 2003-2006 period. The update included in this version applies to 41% of Canada's forest ecozones. This update was carried out using three distinct datasets: 1) Global Forest Watch Canada (2010): Intact Forest Landscapes of Canada circa 2001; 2) Environment Canada (2010) boreal population of woodland caribou herd ranges disturbance dataset, as of circa 2010, and; 3) Global Forest Watch Canada (2013) Alberta Intact Forest Landscapes Update as of circa 2010. Intact forest landscapes were originally mapped by excluding the following types of disturbances and associated buffer exclusion zone from potential intact forest landscapes: 1. Settlements; 2. Infrastructure used for communication between settlements and industrial sites; or for industrial exploitation of natural resources (including roads, railways, navigable waterways, pipelines, trunk power transmission lines and other linear disturbances); 3. Agricultural lands; 4. Territories disturbed by economic activities during the last 30-70 years (logging, major reservoirs, mining operation sites, abandoned agricultural lands, etc.); 5. Artificially restored forests, or tree plantations, if their existence can be detected on Landsat satellite imagery. In addition to the disturbances listed above, large waterbodies (>400,000 ha) and waterbodies which represented more than half of a remaining intact forest landscape fragment were also eliminated from the dataset. It should be noted that some human impacts are invisible from space, such as small forest roads and paths. Other smaller-scale impacts (including some selective logging) that occurred more than 30-70 years ago often become invisible on satellite imagery and indistinguishable from the natural dynamics of the forest. This dataset was created as part of Global Forest Watch Canada's project entitled "What is the Best of What's Left".
