A BioBlitz, also written without capitals as bioblitz, is an intense period of biological surveying in an attempt to record all the living species within a designated area. Groups of scientists, naturalists and volunteers conduct an intensive field study over a continuous time period (e.g., usually 24 hours). There is a public component to many BioBlitzes, with the goal of getting the public interested in biodiversity. To encourage more public participation, these BioBlitzes are often held in urban parks or nature reserves close to cities.
A BioBlitz has different opportunities and benefits than a traditional, scientific field study. Some of these potential benefits include:
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.
Since then, most BioBlitz contain a public component so that adults, kids, teens and anyone interested can join experts and scientists in the field. Participating in these hands-on field studies is a fun and exciting way for people to learn about biodiversity and better understand how to protect it.
In 1998, Harvard biologist E.O. Wilson and Massachusetts wildlife expert Peter Alden developed a program to catalog the organisms around Walden Pond. This led to a statewide program known as Biodiversity Days. This concept is very similar to a BioBlitz and occasionally the two terms are used interchangeably.
A variation on the BioBlitz, the Blogger Blitz began in 2007. Rather than gather volunteers and scientists at one location, participant blogs pledged to conduct individual surveys of biodiveristy. These results were then compiled and mapped. The purpose of this blitz is not to survey down to species level across all taxonomic groups, but rather to raise awareness about biodiversity and provide a general snapshot of diversity.
