Flora
In central and northern Alberta the opening spring brings in the prairie anemone, the avens and other early flowers. The advancing summer introduces many flowers of the sunflower family, until in August the plains are one blaze of yellow and purple. The southern part of Alberta is covered by a short grass, very nutritive, but drying up in the middle of summer until the whole prairie is brown and unattractive. The trees in the wooded sections of the province are seen in clumps and belts on the hill sides. These are largely deciduous. On the north side of the Saskatchewan River forests prevail for scores and even hundreds of miles. They contain the poplar or aspen (Populus tremuloides), balsam poplar (Populus balsamifera), and paper or canoe birch (Fetula papyrifera.) Conifers are found northward and in the mountain valleys. Some of these are: Jack pine (Pinus banksiana), Rocky Mountain pine (Pinus flexilis), black pine (Pinus murrayana), white spruce (Picea alba), black spruce (Picea nigra), Engelman's spruce (Picea engelmanni), mountain balsam (Abies subalpina), Douglas fir (Pseudotsuga douglasii), mountain larch (Larix lyallis.)
