Effect of krummholz establishment on soil previously occupied by tundra: bulk density.

Previous work has shown that bulk density is lower in the A horizon of soils directly under tree islands (Englemann spruce (Picea Englemanii) and subalpine fir (Abies lasiocarpa)) than in adjacent tundra soil. We compiled a dataset of bulk densities from soils that had been previously collected at s...

Description
Summary:Previous work has shown that bulk density is lower in the A horizon of soils directly under tree islands (Englemann spruce (Picea Englemanii) and subalpine fir (Abies lasiocarpa)) than in adjacent tundra soil. We compiled a dataset of bulk densities from soils that had been previously collected at several dates in 1994 and 1996. The results from this large dataset confirmed those of Pauker and Seastedt (1996); soils within tree islands had lower bulk densities from those of other sites.
