Biology and Wildlife University of Alaska Fairbanks 99775-6100 907.474.7929 Grant: OPP 9732126 Data Set Overview: This aboveground biomass data was collected in the four Ivotuk sites at approximately peak season biomass, summer 1998. The ground was defined in this case as the top of the moss layer. The biomass was harvested in 20x 50 cm (1000cm2) plots, with 10 -12 replicates per site. The plant tissues were further separated into live and dead and new versus old growth of leaves and stems. When possible, the biomass was sorted to species level. In general, data has been organized at the plant functional type level. Averages and standard errors (SE) have been calculated. Harvest Dates: MAT: July 29, 1998 MNT: July 9, 1998 SHRUB: July 20, 1998 MOSS: August 6, 1998 Species codes: The species names have been shorted to 6 letter genus species codes.
