Umbrella species are species selected for making conservation-related decisions, typically because protecting these species indirectly protects the many other species that make up the ecological community of its habitat (the umbrella effect). Species conservation can be subjective because it is hard to determine the status of many species. The umbrella species is often either a flagship species whose conservation benefits other species [1] : 280 or a keystone species which may be targeted for conservation due to its impact on an ecosystem. Umbrella species can be used to help select the locations of potential reserves, find the minimum size of these conservation areas or reserves, and to determine the composition, structure, and processes of ecosystems. [2]
Two commonly used definitions are:
Other descriptions include:
Animals may also be considered umbrella species if they are charismatic. The hope is that species that appeal to popular audiences, such as pandas, will attract support for habitat conservation in general. [7]
In the two decades after its inception, the use of umbrella species as a conservation tool has been highly debated. The term was first used by Bruce Wilcox in 1984, [8] who defined an umbrella species as one whose minimum area requirements are at least as comprehensive of the rest of the community for which protection is sought through the establishment and management of a protected area.
Some scientists have found that the use of an umbrella species approach can provide a more streamlined way to manage ecological communities. [9] [10] Others have proposed that umbrella species in combination with other tools will more effectively protect other species in land management reserves than using umbrella species alone. [10] [11] Individual invertebrate species can be good umbrella species because they can protect older, unique ecosystems. There have been cases where umbrella species have protected a large amount of area which has been beneficial to surrounding species. Dunk, Zielinski and Welsh (2006) reported that the reserves in Northern California (the Klamath-Siskiyou forests), set aside for the northern spotted owl, also protect mollusks and salamanders within that habitat. They found that the reserves set aside for the northern spotted owl "serve as a reasonable coarse-filter umbrella species for the taxa evaluated", which were mollusks and salamanders. [12]
Gilby and colleagues (2017) found that using threatened species as umbrellas or "surrogates" for management targets could improve conservation outcomes in coastal areas. [13]
The concept of an umbrella species is further utilized to create wildlife corridors with what are termed focal species. These focal species are chosen for a number of reasons and fall into several types, generally measured by their potential for an umbrella effect. By carefully choosing species based on this criterion, a linked or networked habitat can be created from single-species corridors. [14] These criteria are determined with the assistance of geographic information systems on the larger scale. Regardless of the location or scale of conservation, the umbrella effect is a measurement of a species' impact on others and is an important part of determining an approach.
The bay checkerspot butterfly has been on the Endangered Species List since 1987. Launer and Murphy (1994) tried to determine whether this butterfly could be considered an umbrella species in protecting the native grassland it inhabits. They discovered that the Endangered Species Act has a loophole excluding federally protected plants on private property. However, the California Environmental Quality Act reinforces state conservation regulations. [6] Using the Endangered Species Act to protect termed umbrella species and their habitats can be controversial because they are not as well enforced in some states as others (such as California) to protect overall biodiversity.
Protecting a species like the canebrake has practical applications, as protection measures would have broad environmental value because of an umbrella effect. That is, protecting the rattlesnakes would ensure protection of other wildlife species that use the same habitats but are less sensitive to development or require fewer resources. [19]

Brisbane Water National Park is a national park on the Central Coast of New South Wales, Australia. The national park is situated 70 kilometres (43 mi) north of Sydney and 12 kilometres (7.5 mi) southwest of Gosford. It consists the Brisbane Water and Mooney Mooney Creek waterways.
The Mooloolah River National Park is a nationally protected area located on the Sunshine Coast, Queensland. It covers an area of 830.9 hectares and is bordered by the Mooloolah River to the east, Claymore and Dixon Roads to the west, and the Lower Mooloolah River Environmental Reserve to the south. It is bisected by the Sunshine Motorway with the northern, 161.93 hectare component of the Park being a later addition. The Park was initially vacant crown land prior to national park designation in 1960. Surrounding land uses include livestock grazing, urban development and the campus of the University of the Sunshine Coast. It is the second largest mainland park on the coastal lowlands in South East Queensland after Noosa National Park and represents an example of low-lying coastal floodplain distinctive of the region.

Taunton National Park is situated near the town of Dingo approximately 135 km inland from Rockhampton in eastern Central Queensland, Australia. The park encompasses an area of 11,626 ha within the Northern Brigalow Belt bioregion of Queensland; a region widely recognised to contain considerable biodiversity.
A keystone species is a species that has a disproportionately large effect on its natural environment relative to its abundance. The concept was introduced in 1969 by the zoologist Robert T. Paine. Keystone species play a critical role in maintaining the structure of an ecological community, affecting many other organisms in an ecosystem and helping to determine the types and numbers of various other species in the community. Without keystone species, the ecosystem would be dramatically different or cease to exist altogether. Some keystone species, such as the wolf and lion, are also apex predators.
Habitat conservation is a management practice that seeks to conserve, protect and restore habitats and prevent species extinction, fragmentation or reduction in range. It is a priority of many groups that cannot be easily characterized in terms of any one ideology.
Vernal pools, also called vernal ponds or ephemeral pools, are seasonal pools of water that provide habitat for distinctive plants and animals. They are considered to be a distinctive type of wetland usually devoid of fish, and thus allow the safe development of natal amphibian and insect species unable to withstand competition or predation by fish. Certain tropical fish lineages have however adapted to this habitat specifically.
The Golden Gate Biosphere Network is a voluntary coalition of federal, state and local government agencies, nonprofit organizations, universities, and private partners within the Golden Gate Biosphere region. The Network aims to protect the region's biodiversity and conserve its natural resources. The Network has been part of the UNESCO Man and Biosphere Programme since 1988.GGBN is also part of the US Biosphere Network as well as EuroMAB. It is recognized by UNESCO for its "significance for biological diversity conversation" and organizational efforts involving municipal authorities and private interests.
The northern spotted owl is one of three spotted owl subspecies. A western North American bird in the family Strigidae, genus Strix, it is a medium-sized dark brown owl native to the Pacific Northwest. An important indicator species, the northern spotted owl remains threatened due to continued population decline from human-caused habitat destruction and competition with invasive species, its main competitor being the barred owl.
Gap analysis is a tool used in wildlife conservation to identify gaps in conservation lands or other wildlands where significant plant and animal species and their habitat or important ecological features occur.
The shortgrass prairie is an ecosystem located in the Great Plains of North America. The two most dominant grasses in the shortgrass prairie are blue grama and buffalograss, the two less dominant grasses in the prairie are greasegrass and sideoats grama. The prairie was formerly maintained by grazing pressure of American bison, which is the keystone species. Due to its semiarid climate, the shortgrass prairie receives on average less precipitation than that of the tall and mixed grass prairies to the east.
Great Valley Grasslands State Park is a state park of California, United States, preserving a parcel of remnant native grassland in the San Joaquin Valley. Such a temperate grasslands, savannas, and shrublands biome was once widespread throughout the whole Central Valley. The 2,826-acre (1,144 ha) park was established in 1982. Largely undeveloped, it was formed by combining two former state park units: San Luis Island and Fremont Ford State Recreation Area. Its chief attractions for visitors are spring wildflowers, fishing, and wildlife watching.
The Northwest Forest Plan (NWFP) is a series of federal policies and guidelines governing land use on federal lands in the Pacific Northwest region of the United States. It covers ten million hectares within Western Oregon and Washington, as well as a small part of Northern California.
Edith's checkerspot is a species of butterfly in the family Nymphalidae. It is a resident species of western North America and among the subspecies, entomologists have long been intrigued by their many phenotypic variations in coloration, wing length, and overall body size. Most populations are monophagous and rely on plants including Plantago erecta and Orthocarpus densiflorus as their host species in developing from eggs through to larvae, pupae, and mature butterflies. Males exhibit polygyny whereas females rarely mate more than once. Males devote most of their attention to mate acquisition, and such mate locating strategies such as hilltopping behavior have developed. Climate change and habitat destruction have impacted certain subspecies. Three subspecies in particular, Euphydryas editha quino, Euphydryas editha bayensis and Euphydryas editha taylori, are currently under protection via the Endangered Species Act.
Castilleja levisecta is a rare species of flowering plant in the family Orobanchaceae known by the common name golden paintbrush, or golden Indian paintbrush, listed under the Endangered Species Act in 1997. It is native to British Columbia and Washington, where it is known from eleven remaining populations. It occurred in Oregon but all natural occurrences there have been extirpated. It has been reintroduced to a few areas in Oregon, but it remains to be seen if the plants will survive. The plant is a federally listed endangered species of Canada and was listed as threatened in the United States in 1997. On June 30, 2021, the plant was proposed for delisting due to recovery. Effective August 18, 2023, the U.S. Fish and Wildlife Service issued a rule removing golden paintbrush from the Federal List of Endangered and Threatened Plants
The Bay checkerspot is a butterfly endemic to the San Francisco Bay region of the U.S. state of California. It is a federally threatened species, as a subspecies of Euphydryas editha.
