Observed plant species emergence dates 2002 through 2013

This data set consists of annual observed first dates of emergence and leaf opening by plant species occurring at a study site near Kangerlussauq, Greenland. This is part of an ongoing effort to monitor the timing of plant emergence and species-level variation in emergence timing in relation to observed variation in climate and weather. Observations were recorded on a daily or near-daily basis on multiple, randomly distributed, permanently marked plots. The first date of emergence or leaf opening for each species observed on each plot was recorded as the day of year.
