Advances in the Delivery of Observational Data and Pheno Forecast Maps from the USA National Phenology Network.

The USA National Phenology Network (USA-NPN; www.usanpn.org) serves science and society by promoting a broad understanding of plant and animal phenology and the relationships among phenological patterns, climate, and environmental change. Data collected by citizen and professional scientists through Nature’s Notebook -- a national-scale, multi-taxa phenology observation program -- serve USA-NPN strategic goals of advancing science and informing decisions. Since 2009 over 9,000 Nature’s Notebook participants have contributed over 13 million observation records of plants and animals across the United States to the National Phenology Database. These phenology data and resultant products are being used in a rapidly growing number of applications for science, conservation and resource management, including over 30 peer-reviewed publications to date. Here we describe recent advances in the production and delivery of phenology data products derived from in-situ organismal data. We will also share new approaches to phenology forecasting through the delivery of maps that communicate the timing of spring and invasive pest activity. In this talk we will describe the “Phenology Observation Portal” tool used by USA-NPN to deliver four types of user-customized datasets: (a) Status and Intensity Data, (b) Individual Phenometrics, (c) Site Phenometrics, and (d) Magnitude Phenometrics. We will discuss advances in the delivery and analysis of a broad range of phenological metrics derived from observational data at multiple scales including phenophase onset, peak, and end dates, as well as duration and periodicity. In addition, we will demonstrate a new functionality within the USA-NPN Visualization Tool to generate temporal activity curves that can be used to investigate the shape of phenological behavior and the intra-annual overlap in activity between interacting taxa (e.g. plants and pollinators). Using this tool, we will also show how to explore real-time phenology forecast maps as well as contemporary and historic maps that show the timing of spring across the United States. Finally, we present an overview of the framework we use to ensure data are of high quality. These data can be easily integrated with additional observational datasets, including herbaria, climate, phenocam, and land surface phenology data to create value-added phenology products. We will describe how data are being used for a variety of applications, from predictive phenological model development to validation of remote sensing products. We invite researchers and partners to explore these freely available observational and gridded data resources (www.usanpn.org/data) to address a wide range of science questions and management needs.
