Previous work has shown that bulk density is lower in the A horizon of soils directly under tree islands (Engelmann spruce (Picea engelmannii) 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 than those of other sites.
