Abstract

The surface mineral soil beneath an aspen stand contained about 10 times as many bacteria (Corynebacteria, Mycobacteria, and Nocardia) and 30 to 50 percent more fungi (Trichoderma, Aspergillus, Cephalosporium, and Fusarium) than did soil beneath two conifer stands. These organisms were 10 to 1,000 times more abundant in the surface 10 cm than in the next 15 cm. Red pine had more annelids and fewer arachnids in the forest floor than did white spruce and quaking aspen.

Keywords

Bacteria, fungi, annelida, archnida, decomposer organisms
