Global Tundra Vegetation Change - 30 years of plant abundance data from unmanipulated and experimentally-warmed plots

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. As there is substantial overlap in the datasets used for the two projects (i.e. control plots from warming experiments often also provided a record of long-term change under ambient conditions), we have opted to archive the data from both projects together.
