On May 31, 1996, the first bioblitz was held at Kenilworth Aquatic Gardens in Washington, D.C. A bioblitz is a 24-hour species inventory of a specific area. A group of scientists and volunteers find and identify all the organisms they can in one day. This allows scientists to get an idea of the location’s biodiversity. About 1,000 species were identified at the first bioblitz.
In addition to gaining knowledge about the biodiversity of an area, a bioblitz is about getting people outside and interested in science. Bioblitzes are a great opportunity for scientists and the public to meet, learn, and experience how important natural areas are. National Geographic and the National Park Service collaborated on ten BioBlitzes between 2007 and the NPS centennial in 2016.
