Abstract:

Primary vegetation of the Upper Kuparuk River Region. Approximately 750 km^2 region surrounding the upper Kuparuk River watershed, including the Toolik Lake and the Imnavait Creek research areas, as well as a stretch of the Dalton Highway and Trans-Alaska Pipeline from the Galbraith Lake airstrip to Slope Mountain.

The vegetation of the region was studied and mapped as part of the Arctic Long-Term Ecological Research (LTER) project at Toolik Lake, and the Department of Energy R4D (Response, Resistance, Resilience and Recovery of vegetation from Disturbance) project at Imnavait Creek (Walker et al. 1994, Walker and Walker 1996). Fifty-seven plant communities and land-cover types were recognized during the mapping of the upper Kuparuk River region and were grouped into the 14 physiognomic map units shown, which are compatible with the Circumpolar Arctic Vegetation Map (CAVM Team 2003) and the Alaska Arctic Tundra Vegetation Map (Raynolds et al. 2005).
