Differential Response of Subalpine Meadow Vegetation to Snow Augmentation

Abstract

Experimental results from two subalpine meadows in Wyoming suggest that prolonged snow cover due to winter cloud seeding could increase the productivity of dry meadows while causing a decline in the productivity of mesic meadows. Shifts in species composition may also occur. Though statistically significant, the observed effects were subtle and would be expected primarily in areas where larger snow drifts could develop.
