Relative percent cover was measured for plant species on Arctic LTER experimental plots in moist acidic, dry heath and moist non-acidic tundra, and for Sagavanirktok River plots in tussock and heath tundra, North Slope Alaska 2004.

Relative percent cover was measured for plant species on Arctic LTER experimental plots at Toolik field station in moist acidic and moist non acidic tussock tundra, and dry heath tundra, and on Sagavanirktok River toposequence plots in tussock and heath tundra.

Vascular plant species list, by quadrat, for harvests of tussock , wet sedge and dry heath tundra and a toposequence which included "shrub/lupine," "riverside willow" and "footslope Equisetum" communities North Slope Alaska, Arctic LTER 1983-1996.

Vascular plant species list, by quadrat, for harvests of tussock tundra, wet sedge tundra, dry heath tundra, and a toposequence which also included "shrub/lupine," "riverside willow" and "footslope Equisetum" communities. Includes results of long-term nutrient enrichment, increased temperature, and shade houses in selected tundra types.

Biomass from six vegetation types along a toposequence on a floodplain terrace of the Sagavanirktok River, Alaswka,1988, Arctic LTER.

Biomass was harvested from six vegetation types along a toposequence on a floodplain terrace of the Sagavanirktok River in the northern foothills of the Brooks Range , Alaska (68degrees 46' N, 148 degrees 51' W 50m). The vegetation sites are; upland tussock tundra, "hilltop heath", a "hillslope shrub-lupine", a "footslope Equisetum", a wet sedge tundra, and a "riverside willow".

Plant available NH4, NO3, and PO4 was determined at sites near ARC LTER Toolik acidic tundra and at a toposequence along the floodplain of the Sagavanirktuk River using 2 N KCL and weak HCL extracts, Arctic LTER 1987 to 2002

Plant available NH4, NO3, and PO4 was determined at sites near ARC LTER Toolik acidic tundra and at a toposequence along the floodplain of the Sagavanirktuk River using 2 N KCL and weak HCL extracts. This file complies data collected at different times from 1987 through 2001 and includes initial extracts taken for buried bag method of net nitrogen mineralization.
