Background/Question/Methods Nature’s Notebook, the community-science phenology observing program led by the USA National Phenology Network, is now in its 13th year of data collection. The Nature’s Notebook platform is highly customizable, enabling individuals and groups of observers – such as students in a course, volunteers at a nature center, or members of a Master Gardener chapter – to amass observations to answer their own scientific, management, or outreach-inspired questions while contributing to a larger data resource. The core of Nature’s Notebook is a series of rigorous observation protocols designed to yield robust data for use in research and decision-making applications. These data have been widely adopted for use in classroom learning as well as to support scientific research. We welcome and encourage adoption of this program and use of these data by scientists, educators, and natural resource managers. Results/Conclusions Since the program’s launch in 2009, participants have contributed over 24M phenology records to Nature’s Notebook at over 15,000 sites across the U.S. These data have been used in nearly 100 peer-reviewed studies, enabling researchers to document how the timing of seasonal events are changing differentially among species and across geography, disentangle what cues these seasonal events, and validate satellite imagery. These observations have also been used to establish indicators of live fuel moisture in fire-prone ecosystems, assist Hollywood producers in planning on-location filming, and guide the timing of invasive species management activities to achieve optimal success. In this presentation, we will share how the freely available Nature’s Notebook monitoring platform and data resource have been used by scientists, educators, and natural resource managers as well as how the resources might be utilized by others.
