Aspen Forest
Aspen forest habitat is the most common natural habitat
remaining in Winnipeg and the surrounding region. It is dominated by nearly pure
stands of trembling aspen, often with grassland openings. Where these grasslands
are undisturbed, they still contain native tall-grass or mixed-grass prairie
plants. Where these grasslands are in lowlying areas, they are home to wet
meadow species or they may contain small wetlands. Aspen forest stands mixed
with openings of native prairie are sometimes referred to as "aspen
parkland". Aspen forest also may contain bur oak trees in dry areas and
balsam poplar trees in lowlying, wet areas. Manitoba maple and green ash trees
may also be present.
Sunlight passes easily through the canopy of the aspen
forest, allowing a rich variety of shrubs, grasses and wildflowers to grow in
its understorey. Many of the shrubs provide food (seeds, berries or nuts) for
wildlife. Red-osier dogwood is scatterd through the aspen forest, particularly
in moist locations. Roses, chokecherry, pincherry and saskatoon occur on the
edges of the aspen forest. Disturbed areas are often occupied by wild raspberry.
White-tailed deer, red squirrels, eastern chipmunks, eastern cottontail rabbits
and many birds all take refuge in aspen forest.
