In 2012, 2,045 observers contributed 1,592 sites to the NPDb, encompassing all 50 states, the U.S. Virgin Islands, and Puerto Rico. At the close of 2012 the NPDb contained a total of over 1.6 million phenophase status records. More than half of these records were submitted in 2012. Observers submitted records on 547 species in 2012, including 371 plant species (comprised of 5,584 individual plants) and 176 animal species. Red maple (Acer rubrum) and American Robin (Turdus migratorius) were the most observed plant and animal species in 2012. Plant phenophases related to fruiting and flowering had the most records in 2012 and in all years combined, whereas animal phenophases related to feeding had the most records.

Phenology, or the timing of the annual cycles of plants and animals, is extremely sensitive to changes in climate. We know that plants and animals may adjust the timing of certain phenological events, such as tree flowering or migration, based on changes in weather. However, it’s important that we also understand how the timing of phenological events is changing over longer time frames, as climate conditions change. While some species appear to be adjusting to the increase in unseasonal temperatures, drought, and extreme storms that have come with climate change, not all species are responding at the same speed or in the same ways. This can disrupt the manner in which species interact and the way that ecosystems...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete.
