Since 2007, NPS and the National Geographic Society have collaborated to host one large-scale BioBlitz per year for the ten years leading up to the NPS Centennial in 2016. Each year the BioBlitz is hosted by a different national park close to a major urban area. The two day event includes a 24 hour inventory period in which subject matter experts and citizen scientists work together to identify as many species as possible. The event also includes a biodiversity festival, featuring hands-on learning activities, speakers, and exhibits. Click on each of the host parks below for details.
