Intermediate (dashed line) and final fire perimeter (solid line) are shown. "islands" inside the fire perimeter was used (Figure 4). Additionally, Moose had resprouting browse availa- ble in the burned area during summer 1980; therefore, their food base quickly increased. Data in Table 1 appear to indicate that M oose were attracted to the burn area during June and July 1980, but we hesitate to draw this conclusion. Movements of each Moose viewed independently showed no clear shift of home range into the burn during 1980 as compared with other years. Large wildfires in interior Alaska commonly burn mature or climax forests, which generally have low Moose densities ( Moose/km^; Gasaway and DuBois, unpublished data); therefore, few Moose will be associated directly with wildfires. Moose that are in contact with wildfires similar to the one we observed may not be adversely affected and probably will remain in their home range. In contrast, extremely hot, large, and fast-moving wildfires that leave few unburned inclusions may occasionally kill or tempor- arily force Moose to abandon their home ranges. These factors should be considered when planning prescribed burns or managing wildfire to benefit low density moose populations. When moose density is high adjacent to burns, type of burn is of lesser long- term importance because of the potentially high rates of immigration, as observed in Minnesota (Peek 1974). Additionally, burning in spring or early summer allows some forage regrowth in the same year, thus providing a widespread food source. Burn- ing in late summer or fall in northern latitudes will delay vegetative regrowth until the following spring, which could be a factor in forcing Moose to abandon portions of their home range.
