This dataset contains the percentage cover of plant species, bare ground and litter from twelve 1x1m vegetation monitoring plots. Plots are from two distinct vegetation communities (Herschel, Komakuk) approximately 500m apart. Plots were established in 1999 and monitored in 2004, 2009, 2013, 2014, 2015, 2016 and 2017. Data is presented as total percentage cover per species (not relative cover). Funding was provided by the NERC grant NE/M016323/1.

This dataset contains plant trait measurements for nine plant functional traits (specific leaf area, vegetative height, reproductive height, seed mass, leaf dry matter content, wood density, leaf area, leaf fresh mass, leaf dry mass) collected in situ from tundra plant communities at three sites in the Yukon Territory, Canada. The three sites (Kluane Platueau (60.96 degN, 138.41 degW), Pika Camp (61.22 degN, 138.28 degW), Qikiqtaruk-Herschel Island (69.57 degN, 138.90 degW)) were visited annually from 2014-2017. Funding was provided by the NERC grant NE/M016323/1.
