Nature's Notebook is a national, online program where amateur and professional naturalists regularly record observations of plants and animals to generate long-term data sets used for scientific discovery and decision-making.

Being an observer has connected me even more deeply with life in my neighborhood, and with the lives of individual species that I observe.

Status of Spring

Status of Spring

Spring leaf-out has arrived in the Continental US and most of Alaska. Spring was 1-3 weeks late in the SE, northern Great Plains, MW, and NE and 1-3 weeks early across the central Great Plains and mid-Atlantic. The west is a patchwork of early and late arrival.

Celebrating 10 Years of Nature’s Notebook

Education Coordinator LoriAnne Barnett with Certified LPL Hank VerbaisThis month we highlight the data and data products managed by the USA-NPN that are used by researchers, managers, educators, meteorologists, gardeners, and other members of the public. Read the results of published research that includes data from the National Phenology Database on our Peer-Reviewed Results page. Explore the data yourself via our Visualization Tool and Phenology Observation Portal. See the Status of Spring maps that provide forecasts of when spring leaf out and bloom will arrive and how this year stacks up to a long-term average. Find out whether pests are treatable in your area with our Pheno Forecasts.
