BOX 115526 MANAGEMENT REPORT JUNEAU, AK 99811-5526 BLACK BEAR MANAGEMENT REPORT From: 1 July 2007 To: 30 June 2010 LOCATION 2 GAME MANAGEMENT UNIT: Unit 1A (5,300 mi ) GEOGRAPHICAL DESCRIPTION: That portion of Unit 1 lying south of Lemesurier Point, including all drainages into Behm Canal and excluding all drainages into Ernest Sound. BACKGROUND HABITAT DESCRIPTION Unit 1A includes portions of the Cleveland Peninsula and Misty Fjords National Monument on the mainland, and Revillagigedo (Revilla), Gravina, Annette, and Duke Islands. Most high quality mainland black bear habitat in Unit 1A is confined to a relatively narrow band of forested landscapes between saltwater and the high elevation peaks and ice fields of the coastal mountains. An exception is the broader bays and lower peaks of southern Cleveland Peninsula. Revilla Island has many productive salmon streams, large tracts of young age clear cut stands, and productive forest that provides high quality habitat. Gravina, Annette, and Duke Islands generally have lower-quality black bear habitat. A few large mainland river valleys, such as the Unuk, Chickamin, Blossom, Wilson, Keta, and Marten, as well as many Revilla Island stream systems, support salmon and other anadromous fish. Black bears compete with coastal brown bears for foraging opportunities along most of the productive salmon streams in the area. Portions of Revilla, Gravina, and Annette Islands have been logged and have clear-cuts with habitats in various stages of regeneration. As is the case elsewhere in Southeast Alaska, habitat changes continue to occur from clear-cut logging. Although early successional stages (3–20 years after logging) provide black bears with an abundance of plant foods, later stages result in the disappearance of understory plants as conifer canopies close and sunlight does not penetrate to the forest floor.
