Vegetation monitoring at Sheenjek LTEM site

Repeat sampling of vegetation communities, soils, and permafrost on plots at 5-year intervals.

We established five long-term ecological monitoring sites in the Arctic National Wildlife Refuge, one in each of the major ecological zones of the refuge (Figure 1). An ecological zone is an area with similar climatic regime, vegetation, and topographic patterns, and geomorphic and hydrologic processes. Sites in the boreal forest and coastal-plain tundra were established in 1996 and results were reported in Jorgenson et al. (1997). Sites in alpine tundra, the forest-tundra transition, and the coastal marine zones were established between 1997 and 1999. Results are in this report.

The objectives for these sites were: 1) Monitor vegetation, small mammals, birds, terrestrial invertebrates and physical parameters (e.g. soils, permafrost, weather) on a regular basis at permanent study sites within each of the five major ecological zones to document long-term trends in biological and physical components; 2) Accumulate long-term spatially-explicit databases for many different vegetation, wildlife, and environmental variables at the sites, to allow detection of correlations between variables over time, leading to a better understanding of relationships between ecosystem components and of natural ecological processes functioning in the Arctic Refuge.
