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.

Abstract: 

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.

Methods: 

The data presented here was obtained by determining species
presence in a quadrat from data sheets completed during each harvest.
The productivity and biomass data from those harvests is presented in
other data files (83GSTTB7.XLS, 88GSSABM.XLS, 89GSTTBM.XLS,
94GSWSBM.XLS, 95GSTTBM.XLS, 96GSHTBM.XLS). 20 x 20 cm quadrats were
harvested for plant biomass at peak season (late July-early August) each
year listed. Five quadrats were harvested along a line transect within
each block, except as noted below. Species presence in a plot was
recorded at the time the quadrats were sorted to species, and is
indicated in this dataset for aboveground vascular material only.
The 1983, 1989, and 1995 tussock harvests were of 5 quadrats from
4 blocks; the tussock manipulations began in 1981. The 1988 harvest was
of 5 quadrats in the willow community and 4 quadrats in each of the
other communities, again from 4 blocks. The wet sedge harvest in 1994
was 4 quadrats from Toolik Lake (blocks 1 and 2; begun in 1989) and the
Sag River (block 3; begun in 1985). The heath harvest in 1996 was of 5
quadrats from 3 blocks at Toolik Lake; the heath manipulations began in
1989. For detailed description of nutrient enrichments, greenhouses,
and shade houses, see Chapin et al. 1995 and Shaver et al. in press.

Notes: If a block or quadrat was not sampled at a given harvest, the total
species count will be blank. A total species count of zero indicates no
vascular plants were found aboveground in the harvest.
