Summary

The dataset “Glacier_National_Park_alpine_stream_sampling_watersheds,_2011-2013.shp” is a GIS shapefile of the drainage areas of each of the 129 alpine and glacial aquatic macroinvertebrate collection sites included in an analysis to test the prediction that glacier retreat reduces biodiversity in mountain ecosystems through the loss of uniquely adapted meltwater stream species in Glacier National Park, USA. In conjunction with the dataset “Minimum snow and ice coverage for GNP, 2003-2015”, this dataset was used to calculate the proportion of contemporary ice and snow coverage for each watershed drainage area.

Purpose

Watersheds were delimited, and drainage area was calculated for 129 alpine stream sampling locations in Glacier National Park. This dataset was then used to calculate the proportion of minimum perennial now and ice coverage for each of the sample collection locations. Analysis was used to investigate the effect of ice and snow coverage on aquatic macroinvertebrate communities since the Little Ice Age (ca. 1850).
