Project 366 – Post No. 307 – Deciduous pioneers

What is Project 366? Read more here.

Along the Whitemud Creek old coniferous forest tends to grow at the bottom of the ravine along the creek while deciduous forest tends to cover bank slopes. The deciduous stands consists of trembling aspen and balsam poplar trees along with white birch. These species are typically considered “pioneer” deciduous species, because they can establish and grow where there are not already many other trees. Coniferous trees, such as White spruce, on the other hand, are “shade tolerant”, and can survive and grow under a canopy of aspen/poplar. Eventually the spruce exceed the aspen and poplar trees in height and they become dominant in the upper canopy.
