Description

In 1951 and 1954, vegetation study plots and observations on wildlife reactions to the forest fire of 1950 along the upper Porcupine River, Alaska, were begun by members on the Alaska Cooperative Wildlife Research Unit. Periodically, the study areas were visited and data on vegetation, wildlife usage, and soil formation were collected from both burned and unburned areas in attempt to provide information on basic forest fire ecology and the effects fires have on wildlife populations. A progressive change in both the vegetation and animal populations has occurred with the original white spruce forest being replaced by a shrub stage composed mainly of willows and aspen. Spruce regeneration is almost totally absent from the area. Small mammal populations are increasing slowly in burn areas with ground squirrel activity noted along the edges of the 1951 burn and Old Rampart. Large mammal usage is still mainly limited to travel through the burn but increased usage by moose is expected as browse plants continue to develop. Bird observations indicate a marked increase of species seen in the area since 1951. No definite conclusions on effect on forest soils were reported.
