Brown Bears

Southeast Chichagof Bear project

cheryl_recon_beartrail_treebb_smDuring the summer of 2005 we worked in cooperation with the Sitka Ranger District (USFS) on brown bear habitat assessments at several sites on Chichagof and Baranof Islands. The purpose of the field work was to collect high resolution habitat and signs of use data for a variety of wildlife and human use management questions. The areas surveyed ranged from pristine to highly modified watersheds and provided an excellent overview of existing brown bear habitat conditions on the northern Tongass National Forest. GIS analysis was blended with anecdotal naturalist observations in the final report.

Pack Creek Zoological Area (PCZA) Brown Bear project

Brown bear at Windfall harbor on Admiralty National MonumentDuring the winter of 2005 we completed a Landscape-scale assessment of brown bear habitat with an emphasis on providing management guidance for recreation planning. This work was conducted at the Pack Creek Zoological Area on Admiralty island and is being used by Forest Service managers for long-term planning.

Berners Bay Bears

Aaron standing next to some particularly hot feet.The purpose of this project was to field test survey methods for rapid habitat assessment and signs of its use by brown bears (brown bear quick cruise1), and to provide conservation groups and management agencies high resolution information relevant to bear habitat management in the Berners Bay estuary and near-shore uplands (Fig. 1). Berners Bay was an ideal place to perform a trial of the brown bear quick cruise (BBQC) because it enabled us to add new habitat variables to our existing test record, including: large mainland river location, the presence of black bears, and the presence of moose. Although SEAWEAD did not conduct this research with the intention of gathering data suitable for detailed analysis, we were able to survey critical seasonal feeding areas and traditional travel routes. The resultant data are relevant to an environmental assessment of a proposed road in the area. Funding and in-kind support were provided by Friends of Berners Bay, the Skaggs Foundation, Sierra Club Juneau Chapter, and the US Fish and Wildlife Service. Field crew support was provided by Ayme Johnson and Aaron Wells.

Lake Eva Brown Bears

Roberta is a brown bear who spent a lot of time at Lake Eva, relatively speaking, in 2003SEAWEAD naturalists conducted a brown bear habitat use survey to provide ecological context for a bear/human interaction study, and site intensive information for State and Federal management considerations. The methods were designed to gather descriptive information on the character and quality of the habitat mosaic in the lower Lake Eva watershed, and signs of its use by brown bears. The work involved mapping plant and stream characteristics, mapping perennial bear sign (e.g. trails, sign trees & day beds), and surveying for ephemeral bear sign (e.g. scat, bed activity & signs of feeding). The focus area encompassed approximately 350 acres of the lower Lake Eva watershed (Figure 1). Reconnaissance surveys were conducted at the Lake Eva inlet and in several neighboring drainages to provide a landscape level perspective.
