Giant pandas are considered an umbrella species.

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]

Definitions

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 land use management

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]

Wildlife corridors

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.

In the Endangered Species Act (US)

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.

Examples

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. [18]

<span class="mw-page-title-main">Nature reserve</span> Protected area for flora, fauna or features of geological interest

A nature reserve is a protected area of importance for flora, fauna, funga, or features of geological or other special interest, which is reserved and managed for purposes of conservation and to provide special opportunities for study or research. They may be designated by government institutions in some countries, or by private landowners, such as charities and research institutions. Nature reserves fall into different IUCN categories depending on the level of protection afforded by local laws. Normally it is more strictly protected than a nature park. Various jurisdictions may use other terminology, such as ecological protection area or private protected area in legislation and in official titles of the reserves.

<span class="mw-page-title-main">Keystone species</span> Species with a large effect on its environment

A keystone species is a species that has a disproportionately large effect on its natural environment relative to its abundance, a concept 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, are also apex predators.

Fathom Five National Marine Park is a National Marine Conservation Area in the Georgian Bay part of Lake Huron, Ontario, Canada, that seeks to protect and display shipwrecks and lighthouses, and conserve freshwater ecosystems. Parks Canada has management plans for the aquatic and terrestrial ecosystems, with a multi-action plan for species that are at risk, including endemic species, the Monarch butterfly, the eastern ribbonsnake, and the eastern whip-poor-will. The aquatic ecosystems in the park are also of particular interest. Many fish, shellfish, amphibians, and eels are an attraction for naturalists in the park. Much of this wildlife is accessible to scuba divers and snorkellers in the park. The many shipwrecks make the park a popular scuba diving destination, and glass bottom boat tours leave Tobermory regularly, allowing tourists to see the shipwrecks without having to get wet. Additionally, there are three main popular hiking trails found within Fathom Five National Marine Park that provides visitors with views of old growth forests and the Georgian Bay. The Saugeen Ojibway Peoples have inhabited the Bruce Peninsula and the area that is now Fathom Five National Marine Park for thousands of years. This land provided for their communities and their people with the plethora of wildlife and plant life. They provide the local knowledge about Lake Huron and its ecological value to the reserve, park, and their overall livelihood. Parks Canada and Saugeen Ojibway People's collaboration is said to yield a benefit to both parties with regard to overall ecosystem knowledge.

<span class="mw-page-title-main">Edith's checkerspot</span> Species of butterfly

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

Vaseux-Bighorn National Wildlife Area is a National Wildlife Area in British Columbia, Canada, primarily set aside to protect winter rangeland for California bighorn sheep. In 1979, the Vaseux-Bighorn Wildlife Area was established in response to substantial reduction in wild animal populations in the area. Identified factors contributing to species decline at the time were high predator population, overharvesting of species, and illegal hunting. Land development, cattle raising, and lumbering also might have altered species populations. Under these conditions, the area was able to be classified as a Category IV area by the IUCN and is now used for wildlife habitat and conservation. Even with minimal anthropogenic use of the area, threats persist through invasive species. Recreational use is limited spatially and is only open to the public during the day.
