Natural resource applications of the phenology data and information housed in the National Phenology Database Erin Posthumus and the Staff of the National Coordinating Office, USA National Phenology Network

Phenology Informs Resource Management Indicator of biological responses to climate change Informs: Abundance and distribution of species Functioning of ecosystems (e.g. carbon cycling) Ecosystem services (e.g. pollination) Enquist et al. 2014 Int J Biometeorol

Volunteers contribute ~$2.5B annually to biodiversity research Scientific value often under estimated “Good citizen science gets us fine grain, broad extent data we can't collect, or afford to collect, any other way,” - author Julia Parrish Quality Assurance/Quality Control

Gridded maps of spring onset based on PRISM (1981- 2014; 4km) 7-day forecasts for start of spring (2.5 km) Accumulated temperature maps, anomaly maps Planned for spring 2016:
20
Monahan et al. in prep. How has the arrival of spring changed in natural protected areas?
21
Applications: Will spring be extreme relative to other years at a site? Lead time to look out for: Potential for mismatch between interacting species Potential impacts to species that visitors focus on (eg, cherry blooms)

Applications: Wildfire Season An unusually early and warm spring can mean a more intense fire season Photo credit: Denver Post
24
Applications: Getting professional and citizen observers out at the right time Catching phenophases of interest Rare plant monitoring and seed collection
