| Abstract: |
This dataset contains a summary of environmental and stand characteristics of thinleaf alder dominated along the Tanana River floodplains. Environmental data for each site include terrace height, total thickness of organic layers, depth of uppermost organic layer, soil pH, soil C, N, and P, and soil N/P ratio. Also included are mean thinleaf alder foliar C, N, and P concentrations and foliar N/P ratio for a sumbsample of sites. Estimates of stand age, based on the age of the oldest alder, are available for a subsample of sites. Other stand characteristics include canopy cover, stem density and basal area of thinleaf alder, willows, balsam poplar, and white spruce, and % of alder stems infected with a fungal stem canker at various degrees of disease severity.
