Red maple is our most frequently observed plant with over 700,00 records and American Robin is our most frequently observed animal with over 190,000 records. Data on these species and over 1200 other species on the Nature's Notebook list are freely available for download and use. Download them from the Phenology Observation Portal or explore them on the Visualization Tool.
