It is, in essence, one continuous protected area with Wrangell-St. Elias and Glacier Bay National Parks and Preserves in Alaska, Kluane National Park and Reserve in the Yukon Territory, and Tatshenshini-Alsek Provincial Park in British Columbia forming its core. In total these four parks protect 98 300 km2 and combine to form the largest UNESCO World Heritage Site (Danby and Slocombe 2002). In addition to these four core areas there are several other peripheral protected areas, including Tetlin National Wildlife Refuge, Chugach and Tongass National Forests, Kluane Wildlife Sanctuary, and Chilkat Bald Eagle Preserve (Figure 1). Methods Information pertaining to each of the four core protected areas in the St. Elias region, as well as the Tetlin National Wildlife Refuge, was integrated to create a standardized, region-wide checklist of birds and mammals previously recorded within each area. Relative abundance was not included because pres- ence of a species was the only information which was common to all information sources. Analysis of the checklist was carried out with a view to charac- terizing the region's broad biogeographical nature. The list was generated by combining information from numerous different sources. This task was, however, not as straightforward as initially expected. While each of the five protected areas maintain species checklists, they are in different formats and categorize the status of species quite differently. Moreover, taxonomic nome
