Term Response

Natural burns are common in the boreal forests of the Rocky Mountains. While a considerable amount of research has focused on post-burn responses of vegetation and, more recently, large mammals, there have been few studies on responses of small mammal communities in these forests. The primary objective of this study was to revisit study sites on Huckleberry Mountain established immediately following the 1988 Yellowstone fires (Stanton et al., 1991, 1992; Spildie, 1994) to assess small mammal population trends, community structure, and microhabitat preferences on adjacent burned and unburned study sites 9 years post-burn.

Mammal Communities

One primary objective of this study was to survey small mammal communities in a burn chronosequence. During the summer of 1990, small mammals were live-trapped in five burned sites and in adjacent unburned coniferous forests in and around Grand Teton National Park. In 1991, two burns (Huckleberry Mountain, 1988 fires) and adjacent unburned forests were trapped for the third consecutive year in June, July and August to continue to monitor post-burn small mammal population trends and species composition. In addition, in 1991 rodents were live-trapped from seven vegetation types along an elevational gradient, and microhabitat measurements were made at successful and unsuccessful trap stations within each vegetation type. The purpose was to survey small mammal communities in common habitat types within the Park and to determine whether microhabitat features can be used to predict trap success for common rodent species.

Mammal Communities

We studied the small mammal community across a mosaic of habitats created by a large wildfire in the mixed-wood boreal forest of Alberta, Canada, 5 years after the fire occurred. We focussed on four habitat types within this landscape mosaic, namely burnt stands, stands of unburnt forest within the burn, unburnt forest on the periphery of the fire, and areas harvested before the fire (and subsequently burnt). The abundance of the two most common species – red-backed voles (Clethrionomys gapperi) and deer mice (Peromyscus maniculatus) – often differed inside v. outside the burn’s perimeter; however, reproduction, survival and abundance showed little to no correlation with habitat. Year-to-year changes in the relative abundance of these two species appeared greater within the burn’s periphery; the heterogeneity of the burnt landscape also supported a higher diversity of small mammal species than seen at the periphery. Comparison of our results with those collected by a coincidental study of forest harvesting suggests that the responses of the communities and populations of the animals to the two disturbance types were relatively similar. The value of long-term and chronosequence studies notwithstanding, detailed study of the wildlife communities shaped by individual wildfires improves our overall understanding of the ecological effects of natural and anthropogenic disturbances.

Anthropic activities are frequently related in many ways to forest fragmentation and alteration of natural communities. In this study, we correlate the presence of hunting, tourism activity, agriculture/pasturing, and the distance of the study sites to the nearest human residences with the species composition of small Atlantic forest mammals. To do this, we utilize a multiple regression analysis of similarity matrices. The presence of both agriculture/pasturing and human residences near the study sites proved to be determinant factors in species composition of small mammals of the studied areas. Working with socioeconomic variables related directly with the study site could be a reliable and a direct way to predict the influence of human presence and entailed activity on small mammal communities.
