The purpose of this report is to summarize the history of human‐bear interactions in the vicinity of the Congdon Creek campground between 1976 and 2013. The goal is to trace the development of the campground as well as an adjacent solid waste landfill and document, to the extent possible, the number and variety of human‐bear interactions that have occurred in the area over the last 37 years. This will serve as useful background information as we proceed with our experimental removal of soapberry bushes in the immediate campground area and will help determine if the number of human‐bear conflicts in the area is affected by removing natural attractants within the campground.

Snowmachines and the alterations made to the landscape from their activity can have profound impacts on the dynamics of wolves (Canis lupus ) and their prey. Snowmachine activity can displace animals and disrupt their activity and movement patterns; conversely, the creation of trails can enable energy-efficient travel by wolves, thereby increasing the likelihood of encountering and successfully capturing prey. High hunting and trapping pressure could exacerbate these effects, particular during critical late-winter periods when animals are most stressed and anthropogenic activity is greatest. With its dense network of trails, the Nelchina Basin in south-central Alaska presented a unique opportunity to assess quantitatively...

We studied the dynamics of a wolf (Canis lupus) population recovering from intensive reduction in the Finlayson Lake area, Yukon, Canada. Within 6 years, numbers increased from 29 wolves, then stabilized at 245. The colonization of vacant territories by young wolf pairs was the primary mechanism of early population recovery. Reproduction and a low dispersal rate increased pack size in later years, and pack splitting allowed dispersing wolves to remain near natal packs. The rate of increase in the wolf population was density-dependent and related to wolf density, but was also related to the dispersal rate. The dispersal rate was density-independent and related to mean pack size and prey biomass: wolf index. The survival...

Evaluation of snow track surveys being used to monitoring distribution and density of wolves on Tetlin National Wildlife Refuge and adjacent areas.
Yellow-cheeked voles occupy early successional habitats in boreal regions, but specific factors influencing the species' distribution and population dynamics are not well known. Yellow-cheeked voles were studied in three early post-fire habitats in interior Alaska to relate population parameters to habitat characteristics. Voles were live-trapped during June, July, and August of 1997 and 1998, and habitat components were measured withing trapping grids. Capture data were analyzed using the robust design to estimate vole abundance, density, survival, and recruitment. Yellow-cheeked voles were most abundant in the floodplain white spruce, where survival was stable and recruitment was high. The white spruce habitat...
