The Phenology Visualization Tool lets users explore observational data collected via the Nature’s Notebook program. Nature’s Notebook collects information on plant and animal phenology (seasonal change) across the U.S. with the help of individuals or groups that act as observers. The Visualization Tool provides access to this information through a map-based interface.
Users can see the number and location of records that have been collected for specific species and phenophases (e.g., flowering, hatching). They can filter data by year, species, phenophase, and/or partner group that collected the observations. Users can then plot data to explore the relationship between climatic or environmental variables like spring temperature or precipitation, and species phenophase onset dates; or view data on species observations relative to one another. The tool does not make any predictions about phenology under future climate, but can be used for observing recent trends.
The visualization tool provides an online map-based interface for USA National Phenology Network data observations collected across the United States. Users can explore recent trends for species seasonal changes or phenophases (e.g., flowering, hatching), as they relate to climate variables or to one another.
The tool is based on observational data that have already been collected using a status monitoring approach. Users need to:
Select data of interest: filter data by year, species, and/or partner group that collected the observations.
Select geographic area or layer of interest (optional)
The map displays the number and location of observation records that have been collected for user-selected species and phenophases. Users can apply filters to select data of interest, and plot them two ways: 1) A scatter plot of onset observation dates of species phenophases vs. selected climatic or environmental variables or 2) A phenology calendar, where users can view the overall timing of activity of species phenophases alongside one another (e.g. lilac flowering and insect emergence). Custom data selections and graphs can be shared and downloaded.
