The term "BioBlitz" was first coined by U.S. National Park Service naturalist Susan Rudy while assisting with the first BioBlitz. The first BioBlitz was held at Kenilworth Aquatic Gardens, Washington, D.C. in 1996. Approximately 1000 species were identified at this first event. This first accounting of biodiversity was organized by Sam Droege (USGS) and Dan Roddy (NPS) with the assistance of other government scientists. The public and especially the news media were invited. Since the success of the first bioblitz, many organisations around the world have repeated this concept.
