Description

This data set shows areas of essentially undisturbed tracts of forest landscapes greater than 50,000 ha in Canada. The methodology differs slightly from the [global Intact Forest Landscapes methodology](http://www.intactforests.org/method.html) to better reflect the situation in Canada; notably, fires are treated as a natural disturbance even when they touch infrastructure. By mapping the remaining intact forest landscapes within Canada’s forest ecozones, GFWC aims to provide better information for balancing industry needs and values with the need for recognition of non-market values, many of which are associated with relatively undisturbed forests. This data set is based on the results of the circa 2000 IFL data set released in 2010. Forested landscapes greater than 50,000 ha were selected and anthropogenic disturbances were mapped and buffered. The following types of disturbances and associated buffer exclusion zone were excluded from potential intact forest landscapes: settlements (500 m buffer); infrastructure such as roads, railways, pipelines, etc. (1000 m buffer for major roads/highways, 500 m buffer for other infrastructure); agricultural lands (500 m exclusion zone); disturbance in the past 30-70 years from economic activities such as logging, mining, reservoirs, agriculture, etc. (500 m buffer); and tree plantations (500 m buffer).
