Abstract

Abstract

Little published data exist reporting growing season soil temperatures under native vegetation in the Northern Rocky Mountains. In this study soil and air temperatures were measured in meadow, ecotone, and forest vegetation at 2,300 m elevation on the Bangtail Ridge near Bozeman, Montana. Mean annual soil temperature measured at 50 cm was 3.0°C for meadow sites, 2.6°C for ecotone, and 1.8°C for forest sites. Winter soil temperatures for the three types were similar but summer soil temperatures were nearly 5° C warmer in meadows than in forests and intermediate in the ecotone. Temperature variation was greatest in the meadow, intermediate in the ecotone, and least in the forest.
