Chapter 5: Vegetation

5.11: Vegetation in the Central Part of Duck Mountain

The photograph shows the lake-strewn central part of Duck Mountain. On the image lakes show in various grey tones, depending on their depth, suspended sediment load, and the sun/camera/water surface relationship (the specular reflection effect). East Blue Lake 1, West Blue Lake 2, Swallow Lake 3, Beautiful Lake 4, Whitemud Lake 5, Elk Lake 6, Island Lake 7, and Singush Lake 8 all appear as dark grey, whereas Cache Lake 9 is light grey, and a small, unnamed lake in the east 10 is almost white.

Almost the whole area is covered by natural vegetation, in this area mixed woods consisting of coniferous trees on higher land and birch (Betula papyrifera) and aspen (Populus tremuloides) in better-drained lowlands. The dominant trees are probably white spruce (Picea glauca) and black spruce (Picea mariana). Wooded areas are dark-toned 11 with light-toned areas of aquatic vegetation surrounding some of the lakes 12. It is noticeable, however, that the northwest is lighter toned 13, the result of a forest fire. This is the same scar that can be seen on the LANDSAT image in figure 5.10.

The area is almost devoid of human occupation, but some recreational development is seen at the north end of East Blue Lake 14 and south of Marge Lake 15. Two major transport routes intersect on the photo: the east/west PR 367 16 and north/south PR 366 17.
