Physical and Chemical Properties of the Forest Floor in Birch and Aspen Stands in Interior Alaska1

This study was conducted to establish the mass and nutrient status of the forest floor in quaking aspen (Populus tremuloides Michx.) and paper birch (Betula papyrifera Marsh.) forests in interior Alaska. Results of this investigation show that aspen forests have a greater mass of organic matter and nutrient elements in the forest floor than birch forests. The more favorable base status in aspen forest floors is reflected in higher pH and lower exchangeable hydrogen than encountered in birch forest floors. Increasing degree of organic matter decomposition in the forest floor of both vegetation types (L layer > F layer > H layer) is associated with increased N content and cation exchange capacity of the organic matter in the respective layers.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
