Fig. 2. Local changes such as seen in Figure 1 are occurring in varying degrees across very large areas of the Canadian boreal, including this region of the boreal plains ecozone in Saskatchewan and Manitoba. The areas labelled “Anthropogenic change” are alterations to natural forest cover over the period 1990 to 2000. The areas coloured in yellow (Treeless area) would for the most part have been forested prior to European settlement, but have since been converted to agricultural land use, a process that continues to this day (Hobson et al. 2002).
