Alaska: The Chugach National Forest and Alaska Department of Fish & Game-Diversity Program organized the first BioBlitz in Southcentral Alaska on 23 and 24 July 2011, to coincide with the International Year of Forests. Arizona: More than 5,500 people, including 2,000 students and 150 scientists, attended the 2011 Saguaro BioBlitz, (21–22 October) and discovered 859 species during the 24 hour inventory period. Included in that total were more than 400 species, mostly invertebrate animals and non-vascular plants, which were previously unknown in the park. The accompanying Biodiversity Festival had an integrated art program that included pieces featuring local species, created by local students, seniors, and artists. California: The Santa Monica Mountains NPS/National Geographic Society BioBlitz (30–31 May 2008) was accomplished through collaboration with the Santa Monica Mountains Conservancy, California State Parks, and Los Angeles Recreation and Parks Department. Six thousand participants discovered more than 1,700 species during the 24 hour inventory period. California: The San Diego Zoo Institute for Conservation Research hosted a BioBlitz in the San Dieguito River Park on the North Shore of Lake Hodges in Escondido 25–26 April. California: The San Diego Natural History Museum began hosting a yearly BioBlitz starting in 2008. The 2008 BioBlitz was held in Balboa Park and in 2009 the event was held at Mission Trails Regional Park on 1–2 May. California: The Santa Barbara Botanic Garden organized a BioBlitz of its natural spaces in May 2007. California: Golden Gate National Recreation Area: On 28–29 March 2014, participants in the BioBlitz at Golden Gate Park sites, including Pt. Reyes National Seashore, Muir Woods National Monument, the Presidio of San Francisco, Mori Point, and Rancho Corral de Tierra observed and recorded biodiversity in habitats ranging from the redwood canopy to windswept beaches. Highlights included the first ever canopy survey of redwoods at Muir Woods, the first-ever, park sighting of a climbing salamander in Muir Woods; sightings of great horned, spotted, barred and saw-whet owls; and a mountain lion at Corral de Tierra. Colorado: The National Wildlife Federation has been providing a toolset based on the eNature.com species data in the Denver/Boulder metropolitan area since 2004. Results are online. Colorado: On 24–25 August 2012, more than 150 scientists joined forces with 5,000 people of all ages and backgrounds to seek out the living creatures in Rocky Mountain National Park. Inventories took place in various ecological life zones, including ponderosa pine forests, the subalpine region, the tundra, and mountain meadows. Among the overall total of 490 species discovered, 138 were previously unknown to be in the park. A companion festival at the Estes Park Fairgrounds advanced and celebrated public awareness of biodiversity. Connecticut: The Center for Conservation and Biodiversity and Connecticut State Museum of Natural History have held nine BioBlitz events since 1999. The current record for a single Connecticut BioBlitz was set 3–4 June 2016 in a 5-mile radius around the Two Rivers Magnet School in East Hartford, where 2,765 species were recorded in the 24-hour period. Many of the organisms sighted in the 2016 BioBlitz were documented in an online iNaturalist project. The previous record was set in 2001 at Tarrywile Park in Danbury, where 2,519 species were recorded in the 24-hour period. District of Columbia: A BioBlitz at the Kenilworth Park and Aquatic Gardens in Washington, D.C. in 1996 found approximately 1000 species. Washington, D.C. 2007: The National Geographic Society held a BioBlitz in Rock Creek Park on 18–19 May. The event was later on a segment of the TV series Wild Chronicles which airs on PBS. Participants included J. Michael Fay, Sylvia Earle, and Boyd Matson. The first National Park Service/National Geographic Society BioBlitz took place on 18–19 May 2007. A wide breadth of taxonomic groups was examined, including amphibians and reptiles, invertebrates, birds, fish, fungi, mammals, plants, insects, and more. The total number of species found was 661 over a 24-hour period. Florida: In Manatee County, the local government's Department of Natural Resources (formerly Conservation Lands Management) has sponsored annual BioBlitz events, every spring since 2007. The surveys rotate between the county's different parks and preserves. This event, however, involves only a 12-hour survey instead of the standard 24-hour. Florida: On 30 April – 1 May 2010, 2,500 citizen scientists worked with their professional counterparts to explore life in one of the nation's largest marine national parks, Biscayne National Park. More than 800 species were found, including a number of species rare to the park, such as the mangrove cuckoo, and silver hairstreak butterfly. Also, 11 species of lichen and 22 species of ants were found that had not previously been documented in the park. Hawaii: At Punahou School, a biannual BioBlitz is organized by the students. The event examines certain parts of the campus, and has been held there since the summer of 2008. The BioBlitz there happens once in winter, and once in summer. Hawai'i: at Hawai'i Volcanoes National Park in 2015, working under the theme of I ka nānā no a ’ike ("By observing, one Learns"), traditional Hawaiian cultural practitioners, "alakai’i," were integrated into the survey teams, providing a holistic approach to the research and exploration activities. More than 170 leading scientists and alakai’i, teamed with thousands of public participants of all ages to explore one of the most fascinating biological landscapes in the world. Together they documented species that thrive in ecosystems from sea level to the summit of Kīlauea Volcano. Exciting finds included 22 new species added to the park's species list, and sightings of 73 threatened species, including the nēnē and Kamehameha butterfly. The number of fungi species on the park's list more than doubled, with 17 new fungi documented at the close of the event. Illinois: The Field Museum of Natural History and other organizations held a BioBlitz in Chicago in 2002. There are several bioblitzes in parts of the forest preserves of Cook and Lake County. Indiana: Indiana Dunes National Park – On 16 May 2009, more than 150 scientists, assisted by 2,000 grade school students and other members of the public, explored the sand dunes, lake shore, forests, wetlands, prairie, and streams of the recreation area. The excitement persevered through driving rain and high winds and resulted in the discovery of more than 1,200 species. Louisiana: The NPS/National Geographic Society BioBlitz at Jean Lafitte National Historical Park and Preserve (17–18 May 2013), brought together leading scientists and naturalists from around the country and local citizens of all ages. Inventories included herpetofaunal counts, aquatic and terrestrial invertebrate inventories, avifauna observations, and native and non-native plant surveys. Participants also used technology, such as tree cameras and smartphones, to record and understand the diverse ecosystems of this unique national park. At the time of the event's closing ceremony, 458 species had been identified, including a rare Louisiana milk snake, 288 plants, and 122 invertebrate species. Maine: The Maine Entomological Society and other organizations have been holding Entomological BioBlitzes at Acadia National Park every summer since 2003. Results of the 2003-2011 blitzes were summarized by Chandler et al., 2012, showing that 1,605 species representing 348 families of insects were taken and identified over the 8-year period.
