Colorado Elevation Gradient Snowmelt Manipulation Plant Phenology 2017-2018

This dataset includes observations of plant phenology at five locations along an elevation gradient in Crested Butte, Colorado. Observations occurred over the years 2017 and 2018. Observations taken in 2018 are associated with an experimental early snowmelt manipulation. The file PhenologyData_complete.txt contains raw data of phenology observations for each year, at each site, for each species within 1mX1m subplots. The file Phenology Data Package.docx contains information about sites, plots, and plant phenophases. These observations were taken to assess the temporal impact of early snowmelt perturbations on plant growth in the East River Valley. These data can be used to inform when and where plants may be using water resources throughout the season and how the phenology of plant communities in the watershed may respond to early snowmelt.本数据集包含美国科罗拉多州克雷斯特德比特（Crested Butte）沿海拔梯度布设的5个观测样地的植物物候观测数据，观测时段覆盖2017年与2018年。其中2018年的观测数据对应一项人工提早融雪的操控实验。完整物候数据文件PhenologyData_complete.txt收录了各年份、各样地、各物种在1米×1米小样方内的物候观测原始数据；配套文档Phenology Data Package.docx则包含样地、样方及植物物候期的相关说明信息。本批观测旨在评估东河谷（East River Valley）区域内提早融雪扰动对植物生长的时序影响，该数据集可用于解析植物群落整季水资源利用的时空规律，以及流域内植物群落物候对提早融雪的响应模式。
