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:
- Enjoyment - Instead of a highly structured and measured field survey, this sort of event has the atmosphere of a festival. The short time frame makes the searching more exciting.
- Local - The concept of biodiversity tends to be associated with coral reefs or tropical rain forests. A BioBlitz offers the chance for people to visit a nearby setting and see that local parks have biodiversity and are important to conserve.
- Science - These one-day events gather basic taxonomic information on some groups of species.
- Meet the Scientists - A BioBlitz encourages people to meet working scientists and ask them questions.
- Identifying rare and unique species/groups - When volunteers and scientists work together, they are able to identify uncommon or special habitats for protection and management and, in some cases, rare species may be uncovered.
- Documenting species occurrence - BioBlitzes do not provide a complete species inventory for a site, but they provide a species list which makes a basis for a more complete inventory and will often show what area or what taxon would benefit from a further study.
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 state-wide 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.

- The Robert Bateman Get to Know BioBlitz started in 2010 to celebrate the international year of biodiversity. In a partnership with Parks Canada there were many sites all across Canada which celebrated bioblitzes on the international day of biodiversity (May 22).
- British Columbia
- There has been an annual BioBlitz in Whistler, BC since 2007. The 2013 BioBlitz reported 497 species.
- Metro Vancouver has hosted their annual BioBlitz at Burnaby Lake Regional Park since 2010. This bioblitz has a large public participation component with lots of activities including pond dipping, nature walks and meeting live animals up close. The species count currently stands at 488, including a Western Screech Owl, Red-legged Frog, Brassy Minnows and Common Fern which, despite its name, had never been found in the area before.
Inactive and historic BioBlitz
- The Canadian Biodiversity Institute held numerous BioBlitzes between 1997 and 2001.

This event comes as part of the ‘Biodiversity Festival 2015’, an Agriculture, Fisheries and Conservation Department (AFCD) lead project that encompasses many events, exhibitions and seminars, and is a major section of Hong Kong’s Biodiversity Strategy and Action Plan (BSAP). Highlights included 2 species of moth that are extremely rare and native to Hong Kong, the first official record of coral in Tai Tam Bay and the first official record of juvenile horseshoe crabs on Hong Kong island.
- An Ireland's BioBlitz Event has been held annually since 2010 - established by the National Biodiversity Data Centre http://www.biodiversityireland.ie/ to celebrate International Year of Biodiversity. A unique feature of this event is that it has a number of parks through the island competing against each other to see which site records the most species over a 24hr period. The event is usually held on the third weekend in May each year.
- In 2010, the first year it was held, Connemara National Park won the competition having recording 542 species. In 2011, Killareny National Park won the event having recorded an astonishing tally of 1088 species. Crawfordsburn Country Park won in 2012 having recorded 984 species. All of the data are made available through an online mapping system, Biodiversity Maps http://maps.biodiversityireland.ie/# and hard copy species lists are produced http://bioblitz.biodiversityireland.ie/bioblitz-species-lists-now-available/
