Phenology Observation Data

Metadata Updated: December 4, 2018

This suite of datasets consists of phenology data on over 1000 species of plants and animals (2009-present) and data on lilacs and honeysuckles (1956-present), across the United States. The data were collected by citizen and professional observers, and archived and distributed by the USA National Phenology Network ( Protocols are available in Denny et al, 2014 and datum is WGS84. This collection represents a suite of three data products: 1) Status and Intensity Data (phenophase status records of presence or absence of the phenophase, as well as information about the intensity with which the phenophase was expressed for each individual plant or species of animal at a site, on each visit by an observer), 2) Individual Phenometrics (estimates of the dates of all onsets and ends of a phenophase for individual plants and for animal species at a site during a user-defined time period) and 3) Site Phenometrics (estimates of the dates of first onset and last end for a phenophase, averaged across individuals of the same species at a site, during a user-defined time period).
