The file “Nabe-Nielsen etal 2017 Young Sund plotgroup data.csv” contains data on average vegetation cover, average number of plant species per plot and average environmental variables in each of 48 plot groups distributed along Young Sund, a High Arctic fjord in Northeast Greenland. The plots are located in three sites: “Zackenberg”, “Blæsedalen” and “Tyrolerfjord”. Each plot group consists of six plots. See the published paper for further details.

Environemental variables include: altitude [m], continentality index [*], slope [degrees], solar radiation index [*], soil water [percent], and temperature [degrees celsius]. *See the paper for definitions of the indices.

The file “Nabe-Nielsen etal 2017 Young Sund spp pres in plotgrps” contains data on the number of plots where each vascular plant species was present within each of the 48 plot groups. Species names are based on nomenclature in Supplementary Information in the published paper.
