Chapter 5: Vegetation

5.12: The Northern Edge of Riding Mountain National Park

The photo shows the sharp demarcation line between the essentially natural vegetation in Riding Mountain National Park 1 and the Gilbert Plains to the north 2, almost completely devoted to agriculture.

South of the park boundary 3 the natural vegetation consists of mixed woods: coniferous trees, including white spruce (Picea glauca) on higher land and black spruce (Picea mariana) with birch (Betula papyrifera) and aspen (Populus tremuloides) on well-drained lowlands. The woodland is represented in very dark-grey tones 4 with lighter-toned areas of aquatic vegetation around small lakes 5. Two large areas of light tone in the southwest 6 and southeast 7 are the result of a forest fire. This area can also be identified on satellite images (figure 5.10).

Drainage from this part of Riding Mountain is to the north via a series of steep-sided valleys, from west to east: East Wilson River 8, Renicker Creek 9, and Ranch Creek 10. These continue northeast across the gently sloping Gilbert Plains. The checkerboard pattern of the DLS is visible in this intensively cropped area. A few small patches of woodland remain 11 as well as fingers of riverine forest along the river courses 12.
