A critical part of the National Park Service’s Arctic Network Inventory and Monitoring Programis monitoring the Western Arctic Caribou Herd (WACH). The status, distribution, movementsand trends in the condition of caribou in all five park units are monitored. Accurate and detailedmodels of snow cover within the range of the Western Arctic Caribou Herd will provideimportant context to help understand movement patterns and timing of caribou migrations. Snowdepth influences caribou winter distribution and habitat availability by impacting the costs oflocomotion and cratering for forage plants and lichens. Snow depth patterns on the landscapealso influence plant communities, affecting the distribution of preferred forage...
This document summarized the effort to derive new map data using reclassification logic or rule-based aggregation processes for WRST. The final map data set retains this highly detailed “bird’s-eye view” level of information in the form of a land cover database. Generalized land cover maps may then be derived from this detailed land cover database. In addition, alternative more directed detailed maps may be derived from the land cover database as needed.
This report presents the results of anecological land survey (ELS) effort that inventoried, and classified ecosystems in the Wrangell-St. Elias National Park and Preserve. By analyzing the dynamic physical processes associated with coastal, riverine, lowland, glacial, hillside and mountainous environments, and the abundance and distribution of their diverse ecological resources, this study contributes to ecosystem management in national parklands in Alaska.
This document summarizes the steps taken to generate the final Katmai National Park and Preserve land cover map.
We used the CRU (1950-1959 and 2000-2009) and projected 5-GCM composite (2001-2010, 2051-2060, and 2091-2100) decadal climate forcing, ecotype (Stevens 2001), soil landscape (Clark and Duffy 2006), and snow (unpublished) maps of DENA to model the presence or absence of near-surface permafrost, temperature at the bottom of seasonal freeze-thaw layer and its thickness within DENA. We produced permafrost temperature, and active-layer and seasonally-frozen-layer thickness distribution maps through this modeling effort at a pixel spacing of 28 m. This is an immense improvement over the spatial resolution of existing permafrost maps on any part of Alaska, whether produced through the spatially explicit thermal modeling...

We produced permafrost temperature and active-layer and seasonally-frozen-layer thickness distribution maps through this modeling effort at a pixel spacing of 28.5 m. This is an immense improvement over the spatial resolution of existing permafrost maps on any part of Alaska, whether produced through the...
