A BioBlitz is a great opportunity to get out into nature and observe all the species of plants and animals (and fungi) that inhabit an area, whether that’s a local park or meadow or someplace you have traveled. During a BioBlitz, participants observe, photograph, and upload their observations to iNaturalist. During NANPA’s recent Nature Photography Day BioBlitz, more than 9,000 observations were logged, covering more than 3,000 species, 97 of which were threatened. The date contributed by participants becomes available to scientists and researchers—a true citizen-science project. We’ve profiled several participants (here, here, and here) already. Today, we turn our attention to Judd Patterson, who works for the National Park Service and pursues nature photography in his spare time. He logged observations of several rare and/or threatened species.
