Abstract
A paucity of life history information on bears has encouraged biologists to test live-trapping techniques. Erickson (1957) and Black (1958) have reported on methods used on black bears (Ursus americanus) in Michigan and New York. In Yellowstone National Park, Craighead, et al. (1960) have developed methods for handling grizzly bears (Ursus horribilis). This paper deals with the methods employed to live-trap brown bears (Ursus middendorffii) on the Kodiak National Wildlife Refuge in Alaska. This study was conducted in the Karluk Lake drainage. Red salmon (Oncorhynchus nerka) spawn in the lakes and tributaries in summer and fall months. Since salmon are an important food item for brown bears, they concentrate along streams and lake shores during this period and may be successfully trapped. Travel within the study area was by foot and boat as no roads exist on the refuge. Investigations were conducted in the summers of 1957 through 1961.
