The USA NATIONAL PHENOLOGY NETWORK PHENOLOGY as an INTEGRATIVE SCIENCE for ASSESSMENT of GLOBAL CHANGE IMPACTS Jake F. Weltzin and Mark Losleben USA National Phenology Network, National Coordinating Office, Tucson, Arizona NPN Tier 1: Examples of Intensive Sites USA-NPN Collaboration Plan A National Phenology Network Ameriflux National Ecological Observatory Network (NEON) Phenology is an essential component of the biosphere Long Term Ecological Research (LTER) Experimental Forest and Range Synthesis Network Adapted from Bonan (2002) Ecol. Climatology Global Change Influences & is Influenced by Phenology Tier 2: Example of Spatially Extensive Science Networks GOALS Phenology is the study of periodic plant and animal life cycle events and how these are influenced by seasonal and interannual variations in climate. Examples include the timing of leafing and flowering, agricultural crop stages, insect emergence, and animal migration. All of these events are sensitive measures of climatic variation and change, are relatively simple to record and understand, and are vital to both the scientific and public interest. Phenology can be used as a predictor for a variety of processes and variables of importance at local to global scales. Phenology modulates the abundance and diversity of organisms, their inter-specific interactions, their ecological functions, and their effects on fluxes in water, energy, and chemical elements at various scales. Phenological data and models are useful in agriculture, drought monitoring, and wildfire risk assessment, as well as management of invasive species, pests, and infectious diseases. Integration of spatially-extensive phenological data and models with both short and long-term climatic forecasts offer a powerful agent for human adaptation to ongoing and future climate change. To fully utilize the value in phenological data, however, a new data resource is required – a large-scale network of integrated phenological observations, linked with other relevant data sources, and the tools to analyze these data at multiple scales. A USA National Phenology Network (USA-NPN) is currently being designed and organized to engage federal agencies, environmental networks and field stations, educational institutions, and mass participation by citizen scientists. -To advance the USA-NPN scientific mission to understand and predict shifts in phenological cycles due to climate change and natural variability. NPN Network Structure -benefit from and contribute to many existing organizations that are concerned about nature and climate. -Maximize resources through close collaboration with organizations. This represents not only the best use of available resources but also the best scientific practice. PLAN -Coordinate research activities with existing networks to advance phenological science and develop mechanistic phenological models to support improvement of climate and ecosystem models. -Maximize the representation of phenological monitoring sites at the national and regional scale to enable biological baseline characterization and trend detection. - Provide data and information to policy makers to support land management decisions in regard to the mitigation of climate change impacts. PRIORITIES - Establish coordination between NPN and existing networks - Identify constraints and needs of existing networks and develop tailored collaborative items suitable for each network - Nurture common interests\develop collaborative research projects - Organize joint workshops - Distribute NPN newsletters PHENOLOGY: THE PULSE OF OUR PLANET PRINCIPLES - Mutually beneficial activities - Shared vision on science / education / outreach - Minimizing the demand on the capacities of partners - Feedback to improve collaboration - Transparent data and information sharing policy Integration of spatially-extensive phenological data and models with both short and long-term climatic forecasts offer a powerful agent for human adaptation to ongoing and future climate change.
