USA National Phenology Network Research Coordination Network Meeting; Milwaukee, Wisconsin, 22–23 May 2012 Phenology is the study of reoccurring life cycle events in plants and animals, such as bird migrations, emergence from hibernation, flowering, and carbon cycling. Changes in the timing of phenological events are widely recognized as indicators of the effects of climate change on ecosystems. Phenological data can be used to inform wildlife management, wildfire and pollen forecasting, and the planning of events such as the National Cherry Blossom Festival. Until recently, collection of phenological data using standardized methods was relatively rare, limiting their use in science, management, and decision making.
