SPRUCE Ground Observations of Phenology in Experimental Plots, 2019
This data set consists of phenological transition dates, as derived from direct observations of vegetative and reproductive phenology recorded by a human observer, from the SPRUCE experiment during 2019, the fourth full year of whole-ecosystem warming (Hanson et al. 2017). Both spring and autumn phenological events are included.
Since April 2016, human observers have been directly tracking the phenology of both woody and herbaceous species on a weekly schedule within the SPRUCE experimental chambers. The observed date reported here is the first survey date on which an event/phenophase was definitively observed.
User note: Ground observations of phenology from 2016-2021 are available. See SPRUCE Ground Observations of Phenology in Experimental Plots 2021. for the most recent data as well as links to all other ground phenology datasets.
