This dataset contains phenological records (timing of life events such as the opening of flowers) for tundra plant species from eight 2x2m monitoring plots. Plots are from two distinct vegetation communities (Herschel, Komakuk, coded in the data as HER and KOM). Plots were established in 2016 and monitored in 2016 and 2017. Data are presented as phenological stages for each monitored plant individual at survey dates across the 2016 and 2017 growing seasons. Flower stalk length, leaf length and new growth length were measured in mm. Active layer depth was measured in cm and was recorded at the corner of each 2x2 m plot. Soil moisture was measured as a percentage. Funding was provided by the NERC grant NE/M016323/1. : Plots were visited on different dates across the 2016 and 2017 growing seasons. During each visit, the phenological stage of marked plant individuals was recorded. The lengths of the longest flower stalks and the longest leaves were measured during each visit. There were five monitored species - Salix arctica - SALARC Salix pulchra - SALPUL Eriophorum vaginatum - ERIVAG Dryas integrifolia - DRYINT Arctagrostis latifolia - ARCLAT There were two distinct vegetation communities - Herschel - HER Komakuk - KOM : Flower stalk length, leaf length and new growth length were measured using digital callipers. A metal probe was used to measure active layer depth. Soil moisture was measured using an electronic soil moisture meter. Resolution: 2x2 meter plots : Data collection methods were consistent across 2016 and 2017.
