The USA-NPN, phenology, and our partners are often in the news. Follow some recent stories below.
Punxsutawney Phil predicts an early spring this year. Our map of accumulated growing degree days shows he may be right, for parts of the country anyway. See what Nature's Notebook observers are already reporting on plants and animals across the country.
Observational data stored in the National Phenology Database were used in 13 peer reviewed publications last year, to identify climate drivers of flowering, validate land surface phenology, document shifts in flowering of milkweeds, and more.
We've just reached the milestone of 15 million records submitted to the National Phenology Database! These data are freely available for download and exploration in the Phenology Visualization Tool.
Several staff members of the USA-NPN will attend the Fall Meeting of the American Geophysical Union this December.

Phenology is highlighted in the Fourth National Climate Assessment as a 'key indicator of the effects of climate change on ecological communities.' Also included are the USA-NPN's Spring Indices, which show a shift to earlier spring leaf-out and bloom across much of the country.
