This study was initiated to examine bulk density and organic matter content differences between soils where Geum (Acomastylis) rossii and Kobresia myosuroides were present. A subset of samples were also measured for total C, N, and P. Paired plots were randomly selected in locations where Kobresia and Geum populations were adjacent to one another. Soil samples were collected from 35 plots, 22 and 13 of which had southerly and northerly aspects, respectively. Soil cores were removed with 3.5-cm interior diameter PVC pipe that was driven into the tundra by use of a rubber mallet. The minimum depth of individual cores was 9 cm, and these depths were recorded at the time of removal (15 July, 19 July, 22 July, and 9 August 1993).
