Canadian Cryospheric Information Network
Global Tundra Vegetation Change
These data were collected in conjunction with two International Polar Year (IPY) synthesis projects, looking at 1. Vegetation responses to warming in sites worldwide and 2. Long-term changes in unmanipulated control plots.
Plot-based data was collected on vegetation abundance (cover, point-frame hits, biomass, subplot frequency, stem-counts) from permanently marked plots, transects, and study areas throughout the tundra biome, and in and out of warming experiments. Criteria for inclusion in the warming treatment analysis were measures of plant abundance in warmed and control plots in at least one year. For the long-term change project, criteria for inclusion were repeat-measurements of plant abundance in unmanipulated vegetation using the same techniques in 2+ study years at least 5 years apart in time. Air and soil temperature data (where available) were also collected +from the study site locations.
