USA National Phenology Network (USA-NPN) Plant and Animal Phenology Data for the United States

In response to the growing need to understand the response of plant and animal species to environmental variation and climate change and to develop a widespread baseline against which future phenological change may be measured, a consortium of scientists and agencies organized the USA-NPN, with a mandate to collect and share phenology data. More information on the USA-NPN can be found at http://www.usanpn.org/about. As of January 1, 2013, the dataset contains phenology data on 591 species of plants and animals, with 7,512 locations registered across the United States. Protocols used are documented in Denny et. al., Submitted (contact [e-mail] for more information). Data were collected using the phenophase status approach (Thomas et. al., 2010; Denny et. al. Submitted). Latitude and longitude given in WGS84 Datum. This is a suite of yearly data sets (Plants beginning in 2009, Animals beginning in 2010) each provided with and without full phenophase definitions. Supplemental Information: Denny, E.G., K.L.
