In an effort to characterize the species and production rates of various upland mosses and their relationship to both site drainage and time since fire, annual net primary production of six common moss species was measured. Several stands located near Delta Junction, interior Alaska, were located. These stands ranged from one to 116 years since fire in well-drained (dry) and moderately to somewhat poorly drained (wet) black spruce (Picea mariana)-feathermoss systems. Moss species composition varied greatly during the fire cycle, with Ceratodon purpureus dominating the earliest years after a fire, Aulacomnium palustre dominating the transitional and older stages, and Hylocomium splendens dominating the oldest, mature...
