FP3A - Met Station

Description:
The mixed balsam poplar and white s[pruce stage is transitional between the deciduous balsam poplar stages and the conifer shite and black spruce stands. In this stand 100 year old balsam poplar are dominant in the canopy but there is a well developed understory of 40 - 50 year old white spruce that are beginning to reach into the canopy. The white spruce range from 20 - 30 cm in diameter with heights of 15-20 m while balsam poplar have diameters of from 30-50cm and are 20- 25 m in height. Density of white spruce is 480/ha and balsam poplar, 300/ha: basal area is 15m2/ha and 9 m2/ha. There is heavy mortality in the balsam poplar because of the prevalence of heart rot. The shrub layer consists primarily of Alnus tenuifolia and Rosa acicularis with a total cover of 50%. The herbaceous and moss layer in this stand is very sparse, perhaps due to frequent flooding and heavy silt deposition. the herbaceous layer covers less than 20% and is comprised of a number of species, the most common being Cornus canadensis, Equisetum arvense, and Carex concinna. Deciduous leaf and twig litter form a thick layer on the forest floor. On downed logs and under some of the larger spruce, however, patches of feathermosses, primarily Hylocomium splendens, occur. Total moss cover is under 10%.
