It is the smallest extant North American deer species. This deer can be recognized by its characteristic size, smaller than all other white-tailed deer. Adult males (known as bucks) usually weigh 25–34 kg (55–75 lb) and stand about 76 cm (30 in) tall at
196-426: A species indicates the likelihood that it will become extinct . Multiple factors are considered when assessing the status of a species; e.g., such statistics as the number remaining, the overall increase or decrease in the population over time, breeding success rates, or known threats. The IUCN Red List of Threatened Species is the best-known worldwide conservation status listing and ranking system. Over 50% of

In 1924, at a conference organized by the American Society of Mammologists (ASM), the debate generated a public split between those in the Survey, promoting eradication, and those from the ASM who promoted some sort of accommodation. Edward A. Goldman, from
490-537: A gruesome death. The female fly mates once in her life, so the infestation can be battled by introducing sterile male flies to the population, causing the females to die out without laying fertile eggs. Other steps to battle the outbreak included injecting deer with antiparasitic drugs, fencing off healthy sections of the population, and tracking a portion of deer with radio collars. The pest was declared as eradicated in April 2017. The outbreak killed 135 deer, roughly an eighth of
588-509: A large extent in the future. Endangered species are addressed through Canada's Species at Risk Act . A species is deemed threatened or endangered when it is on the verge of extinction or extirpation . Once a species is deemed threatened or endangered, the Act requires that a recovery plan to be developed that indicates how to stop or reverse the species' population decline. As of 2021, the Committee on
686-527: A last resort effort. SSP Programs regularly participate in species recovery, veterinary care for wildlife disease outbreaks, and some other wildlife conservation efforts. The AZA's Species Survival Plan also has breeding and transfer programs, both within and outside of AZA – certified zoos and aquariums. Some animals that are part of SSP programs are giant pandas , lowland gorillas, and California condors . Whereas poaching substantially reduces endangered animal populations, legal, for-profit, private farming does

In 1981, the Association of Zoos and Aquariums (AZA) created a Species Survival Plan (SSP) to help preserve specific endangered and threatened species through captive breeding. With over 450 SSP Plans, some endangered species are covered by the AZA with plans to cover population management goals and recommendations for breeding for a diverse and healthy population, created by Taxon Advisory Groups. These programs are commonly created as
980-759: A reduction in whaling and increase population sizes. The actions include prohibiting all whaling in United States waters, the formation of the CITES treaty which protects all whales, along with the formation of the International Whaling Commission (IWC). But even though all of these movements have been put in place, countries such as Japan continue to hunt and harvest whales under the claim of "scientific purposes". Over-hunting, climatic change and habitat loss leads in landing species in endangered species list. It could mean that extinction rates could increase to
1078-470: A species more desirable for collectors and poachers. This effect is potentially reducible, such as in China where commercially farmed turtles may be reducing some of the pressure to poach endangered species. Another problem with the listing species is its effect of inciting the use of the "shoot, shovel, and shut-up" method of clearing endangered species from an area of land. Some landowners currently may perceive

1274-763: A stretch of the Florida Keys from about Sugarloaf Key to Bahia Honda Key . Key deer use all islands during the wet season when drinking water is more generally available, retreating to islands with a perennial supply of fresh water in dry months. By August 2019, most individuals were living on only one of the Florida Key islands, Big Pine Key . Key deer inhabit nearly all habitats within their range, including pine rocklands , hardwood hammocks , mangroves , and freshwater wetlands . The species feeds on over 150 types of plants, but mangroves ( red , white , and black ), silver palm fruit and thatch palm berries make up
1372-512: A subspecies of white-tailed deer which migrated to the Florida Keys from the mainland over a land bridge during the Wisconsin glaciation . The earliest known written reference to Key deer comes from the writings of Hernando de Escalante Fontaneda , a Spanish sailor shipwrecked in the Florida Keys and captured by Native Americans in the 1550s. Key deer were hunted as a food supply by native tribes, passing sailors, and early settlers. Hunting them

1568-423: Is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss , poaching , invasive species , and climate change . The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess
1666-537: Is a critical habitat for many endangered and watched species, as well as many migratory birds. Due to environmental shifts from climate change and the addition of agriculture in the surrounding plains, the system has become almost irreparably damaged. The warming temperatures has caused mass evaporation, leaving the Sea much more saline and with much more exposed playa. This not only damages air quality but also has caused fish kills to accumulate as shown pictured below. This has made
1764-570: Is an example of an endangered subspecies protected under the ESA. The US Fish and Wildlife Service , as well as the National Marine Fisheries Service are held responsible for classifying and protecting endangered species. They are also responsible for adding a particular species to the list, which can be a long, controversial process. Some endangered species laws are controversial. Typical areas of controversy include criteria for placing
1862-519: Is asserted to be one of the leading causes of animal endangerment. According to the US National Park Service : If we can sufficiently reduce greenhouse gas emissions, many of them will still have a chance to survive and recover. NASA scientist James Hanson has warned that in order to maintain a climate similar to that under which human civilization developed and similar to that which so many organisms are adapted, we need to quickly reduce
1960-517: Is at risk of extinction due to climate change if no action is taken. The phenomenon of species shifting their ranges in response to changing climates, finding new or shrinking habitats, illustrates the direct impact of global warming on biodiversity. Another major concern is rising ocean acidity caused from excess CO 2 in the atmosphere. This creates acidic conditions in the ocean which creates an inhospitable environment for fish, plants, and other keystone species such as coral reefs For example
2058-732: Is data from the United States that shows a correlation between human populations and threatened and endangered species. Using species data from the Database on the Economics and Management of Endangered Species database and the period that the Endangered Species Act (ESA) has been in existence, 1970 to 1997, a table was created that suggests a positive relationship between human activity and species endangerment.

In 2006, a habitat conservation plan was enacted by Monroe County and the US Fish and Wildlife Service, which will limit development in primary habitat and provide for additional habitat purchases over the next 15 years. At the end of this period, however, most of the 1,000 acres (4.0 km) of privately owned habitat land on Big Pine and No Name Keys will still be open for further development. Thus, while

Brazil has a broad legal system meant to protect the environment, including its Constitution , as well as several federal, state and local government agencies tasked with protecting the fauna and flora , fining individuals or companies linked to environmental crimes and confiscating illegally taken wildlife. Though such agencies can collect their data, each system operates relatively on its own when it comes to wildlife trafficking. However, both

Although between 1871 and 1940 the Fish Commission and BOF had never had more than three fisheries research ships in commission at the same time — and had three in commission simultaneously only in two years out of their entire combined history — by March 1950,
3626-516: The Bureau began an ongoing legacy of protecting vital natural habitat throughout the United States. In 1939, the Bureau of Biological Survey moved from the Department of Agriculture to the Department of the Interior. On June 30, 1940, the Bureau of Fisheries and the Bureau of Biological Survey were combined to form the Department of the Interior's Fish and Wildlife Service . In 1956, the Fish and Wildlife Service

This came on the heels of Native American traditional ecological knowledge (TEK) gaining acceptance in the scientific community as a reasonable and respectable way to gain knowledge of managing the natural world. Additionally, other natural resource agencies within the United States government, such as
4900-453: The USFWS fleet operated by the BCF. Both before and after the FWS became the USFWS in 1956, ships of its fleet used the prefix "US FWS" while in commission. The BOF usually named its ships after aquatic birds, and ships the FWS inherited from the BOF in 1940 retained those names in FWS service. However, the FWS/USFWS thereafter usually named vessels it acquired after people who were notable in

Therefore, the USFWS works closely with private groups such as Partners in Flight and the Sport Fishing and Boating Partnership Council to promote voluntary habitat conservation and restoration. The Fish and Wildlife Service
5488-630: The agencies and the NGO 's working in Brazil agree that the birds account for about 80% of trafficked species in the country. The relation between wildlife smuggling, other environment crimes under the Brazilian law such as deforestation , and endangered species is particularly intricate and troubling since the rarer the animal or plant gets the most targeted and valuable they become in the black market , which leads to more endangered species in its turn. Additionally, some environment experts and scientists point to

Conservation efforts include the establishment of the National Key Deer Refuge, which consists of about 8,500 acres (34 km) on Big Pine, No Name Key, and several smaller uninhabited islands. Not all of the refuge lands are protected as public lands; despite extensive efforts of the refuge to purchase these private habitat lands for protection in the refuge, about 5,000 acres (20 km) currently remain in private ownership and can potentially be developed. About 1,000 acres (4.0 km) of this privately developable land
6468-531: The importance of environmental policies aimed at reducing CO 2 emissions to lessen the impact of climate change on species. Tools like the IUCN Red List and guidelines for assessing species' vulnerability to climate change are vital for conservation efforts. In addition, climate change can lead to species decreasing in areas where they once thrived, by being forced to migrate or even going extinct from inhospitable conditions, invasive species, and fragmentation. A study cited by WWF found that one in six species

In September 2016, a screw worm infestation was discovered (the first infestation of its kind in the U.S. since 1982) to be affecting the Key deer population, necessitating the euthanasia of affected animals. The screw worm is a fly larva that enters an open wound of a live animal and eats the flesh of the animal from within, leading to

The World Wildlife Fund (WWF) emphasizes that our planet is warming at a rate faster than any time in the past 10,000 years, necessitating species to adapt to new climate patterns, such as variations in rainfall and longer, warmer summers. For example, the U.S. Fish & Wildlife Service highlighted efforts to understand and mitigate the impact of climate change on species through scientific research, modeling, and conservation actions. This includes evaluating
7252-495: The natural fear of humans shown by most of their larger mainland relatives (an example of island tameness ). The deer are often found in residents' yards and along roadsides where plants and flowers grow. This often results in car-to-deer collisions, as the deer are more active (and harder to avoid) at night. Seeing them at dusk and dawn is not unusual. Breeding occurs all year, but peaks in October and December. Territorial activity

However, captive breeding techniques are usually difficult to implement for such highly mobile species as some migratory birds (e.g. cranes) and fishes (e.g. hilsa ). Additionally, if the captive breeding population is too small, then inbreeding may occur due to

The USFWS continued fishery enforcement in Alaska until after Alaska became a state in January 1959, but by 1960 had turned over enforcement responsibilities and some of the associated vessels to the Government of Alaska as the latter assumed the responsibility for fishery enforcement in its waters. The USFWS continued to operate fisheries research ships and

Richard Emslie, a scientific officer at the IUCN, said of such programs, "Effective law enforcement has become much easier now that the animals are largely privately owned... We have been able to bring local communities into conservation programs. There are increasingly strong economic incentives attached to looking after rhinos rather than simply poaching: from Eco-tourism or selling them on for
7644-622: The percentage of farm-raised individuals in the "visible" trade grew from around 30% in 2000 to around 70% in 2007 – they worry that many wild animals are caught to provide farmers with breeding stock. The conservation expert Peter Paul van Dijk noted that turtle farmers often believe that animals caught wild are superior breeding stock. Turtle farmers may, therefore, seek and catch the last remaining wild specimens of some endangered turtle species. In 2015, researchers in Australia managed to coax southern bluefin tuna to breed in landlocked tanks, raising
7742-515: The poison killing ban and transferred the responsibility for predator control to the Wildlife Services program under the US Department of Agriculture's Animal and Plant Health Inspection Service . The Program's mission has evolved to protect "agriculture, wildlife and other natural resources, property, and human health and safety". Pursuant to the eagle feather law , Title 50, Part 22 of
7840-494: The population has made an encouraging rise since 1955, when population estimates ranged as low as 25, and appears to have stabilized in recent years. Still, recent human encroachment into the fragile habitat and the deer's relatively low rate of reproduction point to an uncertain future for the subspecies. In August 2019 the USFWS recommended that the Key deer be "delisted due to recovery". The species remained listed, but its recovery plan
7938-409: The possibility that fish farming may be able to save the species from overfishing . United States Fish and Wildlife Service The United States Fish and Wildlife Service ( USFWS or FWS ) is a U.S. federal government agency within the United States Department of the Interior which oversees the management of fish , wildlife , and natural habitats in the United States. The mission of
8036-417: The press that might have no other option for escaping extinction in its historical range. A November 2023 news article about the 50th anniversary of the Endangered Species Act summed up the problem for Key deer this way: "Rising seas created the Key deer. Rapidly rising seas, a symptom of human-caused climate change, are challenging its continued existence and raising tough questions for the people trying to keep
8134-514: The program has worked with over 2,000 local partners to open 61,000 mi (98,000 km) of upstream habitat by removing or bypassing 3,400 aquatic barriers. The Division of Migratory Bird Management runs the Migratory Bird Program, which works with partners of the USFWS to protect, restore, and conserve bird populations and their habitats by ensuring the long-term ecological sustainability of all migratory bird populations, increasing
8232-472: The red list. A present-day example of the over-hunting of a species can be seen in the oceans as populations of certain whales have been greatly reduced. Large whales like the blue whale , bowhead whale , finback whale , gray whale , sperm whale , and humpback whale are some of the eight whales which are currently still included on the Endangered Species List. Actions have been taken to attempt
8330-471: The responsibility for administering the Endangered Species Act of 1973 with the National Marine Fisheries Service (NMFS), an element of NOAA, with the NMFS responsible for marine species , the FWS responsible for freshwater fish and all other species, and the two organizations jointly managing species that occur in both marine and non-marine environments. The USFWS publishes the quarterly Endangered Species Bulletin . The USFWS's Fisheries Program oversees
8428-815: The short term promises some cushion from extinction, the long-term prospects for the deer remain in doubt. A portion of U.S. Route 1 was also elevated in 2003 to allow the deer to pass safely beneath the roadway, in an attempt to lessen the chance of road kills. However, no decrease in total traffic deaths has been seen. The National Key Deer Refuge encourages people to help keep the Key deer wild by not feeding them. Feeding acclimates them to humans and vehicles, and makes them more likely to be hit and killed by vehicles. Also, hanging around people and developed areas in higher than normal densities makes them more susceptible to diseases, dog attacks, and entanglements in human trash, all of which can lead to increased injuries or death. Endangered species An endangered species
8526-538: The shoulder. Adult females (does) usually weigh between 20 and 29 kg (44 and 64 lb) and have an average height of 66 cm (26 in) at the shoulders. The deer is a reddish-brown to grey-brown in color. Antlers are grown by males and shed between February and March and regrown by June. When the antlers are growing, they have a white velvet coating. The subspecies otherwise generally resembles other white-tailed deer in appearance. Key deer easily swim between islands . Living close to humans, they have little of
8624-870: The socioeconomic benefit of birds, improving the experience of hunting, bird watching, and other outdoor activities related to birds, and increasing the awareness of the aesthetic, ecological , recreational and economic significance of migratory birds and their habitats. It conducts surveys; coordinates USFWS activities with those of public-private bird conservation partnerships; provides matching grants for conservation efforts involving USFWS partners; develops policies and regulations and administers conservation laws related to migratory birds; issues permits to allow individuals and organizations to participate in migratory bird conservation efforts; helps educate and engage children in wildlife conservation topics; and provides resources for parents and educators to assist them in helping children explore nature and birds. The USFWS partners with
8722-409: The species threatened with endangerment that are not included under the protection of laws like the Endangered Species Act. According to NatureServe's global conservation status , approximately thirteen percent of vertebrates (excluding marine fish), seventeen percent of vascular plants, and six to eighteen percent of fungi are considered imperiled. Thus, in total, between seven and eighteen percent of
8820-459: The status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting , restrict land development , or create protected areas . Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration . Human activity is a significant cause in causing some species to become endangered. The conservation status of
8918-486: The system inhospitable to the birds and endangered species relying upon it Captive breeding is the process of breeding rare or endangered species in human controlled environments with restricted settings, such as wildlife reserves, zoos, and other conservation facilities. Captive breeding is meant to save species from extinction and so stabilise the population of the species that it will not disappear. This technique has worked for many species for some time, with probably
9016-681: The west and by 1930 had "extirpated wolves from the Lower 48 and advised and assisted in erasing grey wolves from" Yellowstone and Glacier National Parks. The Survey then turned to the eradication of coyote, coordinated through the 1931 Animal Damage Control Act . With various agency reorganizations, the practice continued more or less apace through the early 1970s but though hundreds of thousands of coyotes were killed, their extreme adaptability and resilience led to little overall population reduction and, instead, their migration into an expanded habitat, including urban areas. Increasing environmental awareness in
9114-517: The world's species are estimated to be at risk of extinction, but the frontier between categories such as 'endangered', 'rare', or 'locally extinct' species is often difficult to draw given the general paucity of data on most of these species. This is notably the case in the world Ocean where endangered species not seen for decades may go extinct unnoticed. Internationally, 195 countries have signed an accord to create Biodiversity Action Plans that will protect endangered and other threatened species. In
9212-410: Was demoted . In the past, Brazil has successfully saved the endemic golden lion tamarin from extinction . Massive campaigns to raise awareness among people by NGO's and governments, which included printing depictions of the golden lion tamarin in the 20 reais Brazilian banknotes (still in circulation), are credited with getting the species out of the critically endangered animals list. There
9310-402: Was amended in 2022 to specify the conditions in which delisting or downlisting would be appropriate. The ongoing rise in sea level, owing to climate change , is a new threat to its remaining habitat on the islands of southern Florida. Beginning in 2023 when assisted migration was newly authorized as a recovery option for endangered species , Key deer was among the animal species mentioned in
9408-507: Was banned in 1939, but widespread poaching and habitat destruction caused the subspecies to plummet to near-extinction by the 1950s. The National Key Deer Refuge , a federally administered National Wildlife Refuge operated by the Wildlife Service , was established in 1957. Recent population estimates put the population between 700 and 800, putting it on the list of endangered species. Road kills from drivers on US 1 , which traverses
9506-477: Was created in 1940 through the combination of two previous bureaus within the Department of the Interior. Its current director is Martha Williams , who was appointed by U.S. President Joe Biden on March 8, 2022. USFWS employs approximately 8,000 people and is organized into a central administrative office in Falls Church , Virginia , eight regional offices, and nearly 700 field offices distributed throughout
9604-579: Was reorganized as the United States Fish and Wildlife Service — which remained part of the Department of the Interior — and divided its operations into two bureaus, the Bureau of Sport Fisheries and Wildlife and the Bureau of Commercial Fisheries , with the latter inheriting the history and heritage of the old U.S. Fish Commission and U.S. Bureau of Fisheries.
