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 (www.usanpn.org). 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),...

The USA National Phenology Network has available a series of gridded products enabling researchers to analyze daily Accumulated Growing Degree Days (AGDD) from 2016 through the current year. Heat accumulation is commonly used as a way of predicting the timing of phenological transitions in plants and animals. Products generated by the USA-NPN begin accumulation on January 1 and use either a 32F or 50F base temperature.
The USA National Phenology Network has available a series of gridded products enabling researchers to analyze historical and contemporary data related to the Extended Spring Indices. The Extended Spring Indices are mathematical models that predict the "start of spring" (timing of leaf out or bloom for species active in early spring) at a particular location (Schwartz 1997, Schwartz et al. 2006, Schwartz et al. 2013). These models were constructed using historical observations of the timing of first leaf and first bloom in a cloned lilac cultivar (S. x chinensis 'Red Rothomagensis') and two cloned honeysuckle cultivars (Lonicera tatarica 'Arnold Red' and L. korolkowii 'Zabelii'). Primary inputs to the model are temperature...
