These files contain data representing the periodic plant measures of all species within each plot in a CSV format. The data presented are phenological development (date of leaf bud burst, inflorescence emergence, flower bud, flower opening, flower withering, seed development, seed dispersal, and senescence), seasonal growth (length of leaf, and length of inflorescence), seasonal flowering (number of inflorescences in flower within a plot), occurrence of events (yes or no for leaf, inflorescence, bud, flower, and seed), and annual growth and reproductive effort (number of leaves, diameter of rosette, number of branches, maximum leaf length, number of inflorescences, maximum inflorescence length, number of buds, number of flowers, and number of seeds) collected weekly or yearly for all plant species during the summers of 1994-2014 for 48 plots (24 experiment open-top chamber plots and 24 control plots) at four sites (Atqasuk Wet Meadow, Atqasuk Dry Heath, Barrow Wet Meadow, and Barrow Dry Heath).
