Island Conservation is a non-profit organization with the mission to "restore islands for nature and people worldwide" and has therefore focused its efforts on islands with species categorized as Critically Endangered and Endangered on the IUCN's Red List. [4] Working in partnership with local communities, government management agencies, and conservation organizations, Island Conservation develops plans and implements the removal of invasive alien species, [5] and conducts field research to document the benefits of the work and to inform future projects.
Island Conservation's approach is now being shown to have a wider beneficial effect on the marine systems surrounding its project areas. [6] [7] [8] In addition, invasive vertebrate eradication has now been shown to have many benefits besides conservation of species. Specifically, the approach has been found to align with 13 UN Sustainable Development Goals and 42 associated targets encompassing marine and terrestrial biodiversity conservation, promotion of local and global partnerships, economic development, climate change mitigation, human health and sanitation and sustainable production and consumption. [9] [10]
To date Island Conservation has deployed teams to protect 1,195 populations of 487 species and subspecies on 64 islands. [11]
The work of Island Conservation is not without controversy, This is documented in the book Battle at the End of Eden. [12] Restoring islands requires removing whole populations of an invasive species. There is an ethical question of whether humankind has the right to remove one species to save others. However, a 2019 study suggests that if eradications of invasive animals were conducted on just 169 islands, the survival prospects of 9.4% of the Earth's most highly threatened terrestrial insular vertebrates would be improved. [13] [14]
Island Conservation was founded by Bernie Tershy and Don Croll, both Professors at UCSC's Long Marine Lab. These scientists learned about the story of Clipperton Island which had been visited by ornithologist Ken Stager of the Los Angeles County Museum in 1958. Appalled at the depredations visited by feral pigs upon the island's brown booby and masked booby colonies (reduced to 500 and 150 birds, respectively), Stager procured a shotgun and removed all 58 pigs. By 2003, the colonies numbered 25,000 brown boobies and 112,000 masked boobies, the world's second-largest brown booby colony and largest masked booby colony. [15]
Much of organization's early focus was working in Mexico in conjunction with its sister organization, Grupo de Ecología y Conservación de Islas, in the Gulf of California and off the Pacific Coast. [16] [17] Subsequently, Island Conservation expanded its geographic scope to the Channel Islands of California, Pacific Coast of Canada, The Aleutians Islands, Hawaiian Islands, and finally to the Pacific, Caribbean, and South America.
Island Conservation has a strong scientific grounding. Over 160 peer-reviewed publications in major journals such as Biological Conservation , Conservation Biology and Proceedings of the National Academy of Sciences have been authored or co-authored by Island Conservation staff and contractors. [18]
As Island Conservation does not have management responsibility over any islands itself, all projects are in partnership with the island owner/manager, island users, local communities and regulatory authorities. Since its founding in 1994, the organization has developed partnerships with over 100 organizations. [19] Partners include conservation organizations, government agencies, regulatory agencies, scientific institutions, and international conservation consortiums. Island Conservation is a member of the International Union for Conservation of Nature (IUCN), Alliance for Zero Extinction, [20] and has a Memorandum of Understanding with the US Fish & Wildlife Service, [21] and BirdLife International, [22] amongst others.
The organization's founding advisory board [23] is composed of prominent scientists, practitioners, and authors in the fields of conservation biology and invasive species including Paul Ehrlich, José Sarukhán Kermez, Russell Mittermeier, Harold Mooney, David Quammen, Peter Raven, Michael Soulé, and Edward O. Wilson.
In this region, Island Conservation currently works in the United States and Canada. In the United States, the Anacapa Island Restoration Project [24] [25] [26] was completed in 2002 and benefited the Scripps's murrelet, Cassin's auklet, and Anacapa Deer Mouse. The Lehua Island Restoration Project was completed in 2006 which benefited Newell's shearwater and black-footed albatross. [27] [28] Subsequently, projects completed include the Hawadax Island Restoration Project [29] [30] [31] in 2008, the San Nicolas Island Project [32] [33] [34] in 2010, and the Palmyra Island Restoration Project [35] in 2011.
Key federal government partnerships in North America include in the US Department of Interior, USFWS, NPS, the US Department of Agriculture-APHIS, National Wildlife Research Center, NOAA, Parks Canada Agency, and Environment and Climate Change Canada. Island Conservation is working with the following non-governmental organizations: Coastal Conservation Association (CA), Bird Studies Canada, American Bird Conservancy, The Nature Conservancy, and Grupo de Ecología y Conservación de Islas.
Since 2010, Island Conservation has contributed to the development and implementation of island restoration projects in Australia (Lord Howe Island [36] and Norfolk Island), French Polynesia (Tetiꞌaroa Restoration Project in 2022, [37] Acteon-Gambier Archipelago Restoration Project [38] in 2015), Tonga (Late Island and numerous small islets), Republic of Palau (including within the Rock Islands Southern Lagoon World Heritage Area [39] ), Federated States of Micronesia (Ulithi Lagoon), and New Caledonia (Walpole Island). Island Conservation is an active member of the Pacific Invasives Partnership. [40] Other key partnerships include Invasive Species Council, [41] BirdLife International, New Zealand Department of Conservation, SPREP and the Ornithological Society of French Polynesia.
In this region, Island Conservation works primarily in Puerto Rico, The Commonwealth of The Bahamas, and the Dominican Republic. In May 2012, Island Conservation and the Bahamas National Trust worked together to remove invasive house mice from Allen Cay to protect native species including the Allen Cays rock iguana and Audubon's shearwater. [42] Since 2008, Island Conservation and the US Fish and Wildlife Service (USFWS) have worked together to remove invasive vertebrates from Desecheo National Wildlife Refuge in Puerto Rico, primarily benefiting the Higo Chumbo cactus, three endemic reptiles, two endemic invertebrates, and to recover globally significant seabird colonies of brown boobies, red footed boobies, and bridled terns. [43] Future work will focus on important seabird populations, key reptile groups including West Indian Rock Iguanas, and the restoration of Mona Island, [44] Alto Velo, and offshore cays in the Puerto Rican Bank and The Bahamas. Key partnerships include the USFWS, Puerto Rico DNER, the Bahamas National Trust, and the Dominican Republic Ministry of Environment and Natural Resources.
In this region, Island Conservation works primarily in Ecuador and Chile. In Ecuador, the Rábida Island Restoration Project was completed in 2010. A gecko (Phyllodactylus sp.) found during monitoring in late 2012 was only recorded from subfossils estimated at more than 5,700 years old. Live Rábida Island endemic land snails (Bulimulus (Naesiotus) rabidensis), not seen since collected over 100 years ago, were also collected in late 2012. [45] This was followed in 2012 by the Pinzon and Plaza Sur Island Restoration Project primarily benefiting the Pinzón giant tortoise, Opuntia galapageia , Galápagos land iguana. As a result of the project, Pinzon Giant Tortoise hatched from eggs and were surviving in the wild for the first time in more than 150 years [46] [47] [48] [49] In 2019, The Directorate of Galápagos National Park with Island Conservation used drones to eradicate invasive rats from North Seymour Island - this was the first time such an approach has been used on vertebrates in the wild. The expectation is that this innovation will pave the way for cheaper invasive species eradications in the future on small and mid-sized islands. [50] [51] [52] [53] The current focus in Ecuador is Floreana Island with 55 IUCN threatened species present and 13 extirpated species that could be reintroduced after invasive mammals are eradicated. Partners include: The Leona M. and Harry B. Helmsley Charitable Trust, Ministry of Environment (Galápagos National Park Directorate, Galápagos Biosecurity Agency), the Ministry of Agriculture, the Floreana Parish Council and the Galapagos Government Council.
In 2009 Chile, Island Conservation initiated formal collaborations with CONAF, the country's protected areas agency, to further restoration of islands under their administration. In January 2014, the Choros Island Restoration Project was completed benefiting the Humboldt penguin, Peruvian diving petrel, and the local eco-tourism industry. [54] [55] The focus of future work includes the Humboldt Penguin National Reserve and the Juan Fernández Archipelago, where technology developed by Wildlife Drones is being used to support conservation efforts. This includes tracking endangered species and collecting ecological data across challenging terrains.
From its earliest days, Island Conservation has prided itself on innovating its tools and approach to eradication projects. Island Conservation implemented its first helicopter-based aerial broadcast eradication on Anacapa Island in 2001 refining technology developed in New Zealand for agriculture and pest control, this has been replicated on more than 10 international island restoration projects since. [56] Island Conservation has developed practices for holding native species in captivity for re-release and mitigating risks to species, including the successful capture and release of endemic mice on Anacapa and hawks on Pinzon. [57]
In 2010, Island Conservation partnered with the U.S. Humane Society to remove feral cats from San Nicolas Island [58] for relocation to a sanctuary on the mainland California. New tools including a remote trap monitoring system, digital data collection system, [59] and statistical decision support tools [60] [61] improved the humanness of removal methods, reduced project cost, and reduced time to declare success. [62]
Following a series of failed eradication attempts in 2012, Island Conservation led a group of international experts to identify challenges on tropical islands [63] resulting in recommend practices for tropical rodent eradications. [64] Applying these lessons [65] following a failed attempt on Desecheo island 2017 resulted in success.
Island Conservation led a horizon scan in 2015 [66] that identified drones, [67] genetic biocontrol, and conflict transformation as critical innovations to increase the scale, scope, and pace of rodent eradications. Since this exercise, Island Conservation formed the Genetic Biocontrol for Invasive Rodents (GBIRd) partnership to cautiously explore the development of safe and ethical genetic technologies [68] to prevent extinctions, supported sustainable community-driven approaches [69] to conservation projects, and implemented the world’s first drone-powered rat eradication. The current focus of the Conservation Innovation program is to advance methods that increase safety, reduce cost, and improve the feasibility of eradicating invasive vertebrates from islands.
The Galápagos Islands are an archipelago of volcanic islands in the Eastern Pacific, located around the Equator 900 km (560 mi) west of the mainland of South America. They form the Galápagos Province of the Republic of Ecuador, with a population of slightly over 33,000 (2020). The province is divided into the cantons of San Cristóbal, Santa Cruz, and Isabela, the three most populated islands in the chain. The Galápagos are famous for their large number of endemic species, which were studied by Charles Darwin in the 1830s and inspired his theory of evolution by means of natural selection. All of these islands are protected as part of Ecuador's Galápagos National Park and Marine Reserve.
Anacapa Island is a small volcanic island located about 11 miles off Port Hueneme in Ventura County, California. The island is composed of a series of narrow islets 6 mi (10 km) long, oriented generally east–west and 5 mi (8 km) east of Santa Cruz Island. The three main islets, East, Middle and West Anacapa, have precipitous cliffs, dropping off steeply into the sea.
The nutria or coypu is a herbivorous, semiaquatic rodent from South America. Classified for a long time as the only member of the family Myocastoridae, Myocastor has since been included within Echimyidae, the family of the spiny rats. The nutria lives in burrows alongside stretches of water and feeds on river plant stems. Originally native to subtropical and temperate South America, it was introduced to North America, Europe and Asia, primarily by fur farmers. Although it is still hunted and trapped for its fur in some regions, its destructive burrowing and feeding habits often bring it into conflict with humans, and it is considered an invasive species in the United States. Nutria also transmit various diseases to humans and animals, mainly through water contamination.
The Polynesian rat, Pacific rat or little rat, known to the Māori as kiore, is the third most widespread species of rat in the world behind the brown rat and black rat. Contrary to its vernacular name, the Polynesian rat originated in Southeast Asia, and like its relatives has become widespread, migrating to most of Polynesia, including New Zealand, Easter Island, and Hawaii. It shares high adaptability with other rat species extending to many environments, from grasslands to forests. It is also closely associated with humans, who provide easy access to food. It has become a major pest in most areas of its distribution.
Pinzón or Pinzon Island is an island in Ecuador's Galápagos Archipelago. It has no permanent population, an area of 18 square kilometers (6.9 sq mi), and a maximum elevation of 458 meters (1,503 ft). Home to giant Galápagos tortoises of the subspecies Chelonoidis duncanensis and Galápagos sea lions, the island has no visitor facilities and a permit is required for legal visits.
Rábida or Rabida Island is one of the Galápagos Islands. It is 5 km2 (1.9 sq mi) in area.
The ecological restoration of islands, or island restoration, is the application of the principles of ecological restoration to islands and island groups. Islands, due to their isolation, are home to many of the world's endemic species, as well as important breeding grounds for seabirds and some marine mammals. Their ecosystems are also very vulnerable to human disturbance and particularly to introduced species, due to their small size. Island groups, such as New Zealand and Hawaii, have undergone substantial extinctions and losses of habitat. Since the 1950s several organisations and government agencies around the world have worked to restore islands to their original states; New Zealand has used them to hold natural populations of species that would otherwise be unable to survive in the wild. The principal components of island restoration are the removal of introduced species and the reintroduction of native species.
Hawadax Island is an island in the Rat Islands archipelago of the western Aleutian Islands in the U.S. state of Alaska. The island was formerly known as Rat Island until May 2012 when it was renamed Hawadax Island, which is an Aleut name meaning "entry" and "welcome". The island has a land area of 10.72 square miles (27.8 km2) and no permanent population. It is within the Alaska Maritime National Wildlife Refuge.
Lehua Island is a small, crescent-shaped island in the Hawaiian Islands, 0.7 miles (1.1 km) north of Niʻihau, 18 miles due west of Kauaʻi and is an uninhabited, 285-acre (1.15 km2) barren islet. Lehua was one of the first five islands sighted by Captain James Cook in 1778 which he spelled as "Oreehoua".
Desecheo is a small uninhabited island of the archipelago of Puerto Rico in the northeast of the Mona Passage; 13 mi (21 km) from the municipality of Rincón on the west coast of the main island of Puerto Rico and 31 mi (50 km) northeast of Mona Island. It has a land area of 0.589 sq mi. Politically, the island is administered by the U.S. Department of the Interior, U.S. Fish and Wildlife Service as the Desecheo National Wildlife Refuge, but part of the Sabanetas barrio of Mayagüez.
Round Island is an uninhabited islet 22.5 kilometres north of Mauritius. It has an area of 1.69 square kilometres and a maximum elevation of 280 metres. The island has been a nature reserve since 1957 and is administered jointly by the National Parks and Conservation Service and the Mauritian Wildlife Foundation. The island has been designated an Important Bird Area (IBA) by BirdLife International.
The Galápagos Islands are located off the west coast of South America straddling the equator. The Galápagos are located at the confluence of several currents including the cold Humboldt Current traveling north from South America and the Panama Current traveling south from Central America make the islands cooler and provide the perfect environment for the unique mix of wildlife that inhabits the islands.
North Seymour Island is a small island near Baltra Island in the Galápagos Islands in Ecuador. It was formed by uplift of a submarine lava formation and is now covered with low, bushy vegetation. It has an area of 1.9 km2 (0.73 sq mi) and a maximum elevation of 28 meters (92 ft). There is no permanent population but a visitor trail has been established approximately 2 km (1.2 mi) in length for guided tours crossing the interior of the island and exploring the rocky coast.
The mangrove finch is a species of bird in the Darwin's finch group of the tanager family Thraupidae. It is endemic to the Galápagos Islands. It was found on the islands of Fernandina and Isabela, but recent surveys have failed to record the species on Fernandina. It has been classified as critically endangered by BirdLife International, with an estimated population of 20–40 mature individuals in 2021, located in two large mangroves on Isabela. A study has shown that the two small populations remaining on Isabela Island have begun undergoing speciation and that one or both populations will eventually become extinct due to a lack of interbreeding.
The Ascension scrub and grasslands ecoregion covers the dormant volcano, Ascension Island in the Atlantic Ocean. As well as shrubs and grasses wildlife on the island includes a range of unique flora and fauna. In particular the surrounding islets are important havens for many seabirds. However the seabird populations on Ascension Island itself have been severely affected by introduced species, especially cats, which were the subject of an eradication campaign between 2002 and 2006.
The Desecheo National Wildlife Refuge is a National Wildlife Refuge in Puerto Rico. It is part of the Caribbean Islands National Wildlife Refuge Complex.
Seabirds include some of the most threatened taxa anywhere in the world. For example, of extant albatross species, 82% are listed as threatened, endangered, or critically endangered by the International Union for Conservation of Nature. The two leading threats to seabirds are accidental bycatch by commercial fishing operations and introduced mammals on their breeding islands. Mammals are typically brought to remote islands by humans either accidentally as stowaways on ships, or deliberately for hunting, ranching, or biological control of previously introduced species. Introduced mammals have a multitude of negative effects on seabirds including direct and indirect effects. Direct effects include predation and disruption of breeding activities, and indirect effects include habitat transformation due to overgrazing and major shifts in nutrient cycling due to a halting of nutrient subsidies from seabird excrement. There are other invasive species on islands that wreak havoc on native bird populations, but mammals are by far the most commonly introduced species to islands and the most detrimental to breeding seabirds. Despite efforts to remove introduced mammals from these remote islands, invasive mammals are still present on roughly 80% of islands worldwide.
Carl Gwynfe Jones, MBE is a Welsh conservation biologist, who has been employed by Durrell Wildlife Conservation Trust since 1985, and a founding member (1984) and current scientific director of Mauritian Wildlife Foundation (MWF). Additionally he is Chief Scientist at Durrell Wildlife Conservation Trust, and an honorary professor in ecology and conservation biology at the University of East Anglia. Often outspoken on the importance of knowing your species and using intuition, empathy and practical knowledge over dogmatic education, Jones is best known for his work in recovering the Mauritius kestrel from just four individuals in 1974, to an estimated 400. Working in the Mascarene Islands since 1979, Jones has led five successful bird restoration projects where the starting population has numbered less than 12 individuals; as a consequence Mauritius has averted more bird extinctions than any other country. Jones has pioneered the use of ecological or taxon replacements to fill the ecological roles of extinct animals and successfully restored levels of endemic vegetation to previously denuded islets. Jones' work has been highlighted in Douglas Adams and Mark Carwardine's 1990 radio documentary Last Chance to See, along with its accompanying book, as well as David Quammen's 1996 book The Song of the Dodo: Island Biogeography in an Age of Extinctions.
Chelonoidis niger duncanensis, commonly known as the Pinzón Island giant tortoise, is a subspecies of Galápagos tortoise endemic to Pinzón Island in the Galápagos.
