European Endangered Species Programme

Last updated

The European Endangered Species Programme (EEP) is a population management programme for animals of the European Association of Zoos and Aquaria (EAZA). [1] It is one of the worldwide assembly of such regional breeding programs for threatened species in zoos. The North America counterpart is the Species Survival Plan (SSP), while Australian, Japanese and Indian zoos also have similar programs. Combined, there are now many hundred zoos worldwide involved in the regional breeding programs. [2] Each EEP has a coordinator who is assisted by a species committee. The coordinator collects information on the status of all the animals kept in EAZA zoos and aquariums of the species for which he or she is responsible, produces a studbook, carries out demographic and genetic analyses, produces a plan for the future management of the species and provides recommendations to participating institutions. Together with the Species Committee, recommendations are made each year about relocating and breeding animals, and the conditions of such a move (breeding loan, exchange, term free disposition, etc.).

EAZA is an organization for the European zoo and aquarium community that links over 340 membership organizations in 41 countries. [3] The mission of EAZA is to promote cooperation for furthering regional collection planning and wildlife conservation, mainly through coordinated breeding programs of wild animals such as EEP and European Studbook (ESB), which is less intensive than the EEP. Even though EEP participation is mainly reserved for EAZA collections, it is possible for non-EAZA collections to be included in these programmes. There are generally however more restrictions on such zoos (which may go as far as only holding non-breeding animals for educational purposes), and on the number of programmes they may participate in.

Sumatran tiger (Panthera tigris sumatrae)

One species which has been handled by EEP was Sumatran tiger which have only a few hundred left in the wild, and only about 7% of their habitat remains. They used to live in all the Sumatran territory, but nowadays most of them can only be found in the mountain regions of the Burit Barisan volcanic area. This species is currently threatened with the destruction of habitat and poaching, for trade of its parts in traditional oriental medicine or as a trophy. The Tiger EEP has made contributions to the conservation of Amur and Sumatran tigers in the wild, via fundraising for wild tiger conservation projects, raising awareness and providing educational opportunities, and assisting with relevant research and training. For example, in November 2011, Sumatran tiger Kirana has delivered 3 cubs at Chester Zoo under EEP which attempts to coordinate breeding between zoos and maintain genetic diversity. [4]

Gorilla (Gorilla gorilla gorilla)

The Gorilla EEP is one of the most intensively managed and oldest breeding programmes in European zoos. The Gorilla EEP was started in 1987 and was run by the Frankfurt Zoological Garden, who continue to maintain the Gorilla Studbook. [5] In the past decade, some major improvements have been achieved in the management of the EEP for the western lowland gorilla Gorilla gorilla gorilla. Neonatal mortality and hand‐rearing rates have decreased; transfers in most cases proved to be successful: almost all gorillas were integrated into their new groups and most animals introduced to a breeding group had their first offspring within 2 years. The results show that the current management approach is successful, and that the population is sustainable and has good genetic health. [6]

Necessity of international cooperation in breeding programmes

For zoo visitors to have the opportunity to see how wild animals look, live, and behave, zoos must ensure that truly wild animals, with all of their natural characteristics, are presented. Zoo animals are vulnerable to three very serious breeding problems inherent to small, artificial populations: inbreeding depression, loss of genetic variability, and accumulation of deleterious mutations. These problems can easily result in loss of original wild traits, and in the expression of heritable abnormalities. If what was once a pure, wild population of animals deteriorates through generations of uncontrolled breeding into inferior or partially domesticated stock, then the animals are no longer suitable for any conservation effort, and the zoos have failed to perform an important educational task.

The effects of breeding captive populations of wild animals over periods of many generations have been well studied. Based on these studies and genetic theory, guidelines for breeding such small populations have been developed. Following such guidelines should sharply reduce possibilities of breeding problems and concurrently should maximize the number of generations in which the original founding diversity can be maintained. Guidelines for captive populations follow some basic principles including beginning with as many "founders" as possible (preferably at least 20-30 of animals), increase the number of individuals within the population rapidly, all individuals from the founder population should have "equal genetic representation" and inbreeding should be avoided. The application of these guidelines, and many others tailored to specific populations, results in strictly controlled breeding programmes in which nothing is left to chance. Only in this manner can healthy and truly wild populations be maintained over a period of one or two hundred years. Such strict control is entirely dependent on cooperation among zoos that hold individuals of the species, as single zoos generally do not have the facilities to maintain a population of adequate size independently.

Challenges

The largest problem encountered in the functioning of the EEP is undoubtedly the actual execution of breeding management recommendations: it is often difficult to develop policies applicable to an entire group of zoos (varying from 10 to well over 50 depending on the species programme) when these are spread throughout several countries with different languages and laws, and with dissimilar political and economic backgrounds. Just the incongruencies in laws can sometimes make exchange of specimens for breeding purposes by two closely situated zoos a formidable task if a border happens to lie between them. Yet successes have been achieved: the growth of the EEP has been considerable since its initiation in 1985. Now more than 200 zoos from 25 European countries are involved in breeding programmes, while the EEP is strongly supported by the various national zoo federations and by the European Community Association of Zoos and Aquaria (ECAZA). Currently, preparations are being made to find a pan-European zoo association that, among other tasks, will be responsible for EEP affairs. [7]

Ex situ conservation literally means, "off-site conservation". It is the process of protecting an endangered species, variety or breed, of plant or animal outside its natural habitat; for example, by removing part of the population from a threatened habitat and placing it in a new location, which may be a wild area or within the care of humans. The degree to which humans control or modify the natural dynamics of the managed population varies widely, and this may include alteration of living environments, reproductive patterns, access to resources, and protection from predation and mortality. Ex situ management can occur within or outside a species' natural geographic range. Individuals maintained ex situ exist outside an ecological niche. This means that they are not under the same selection pressures as wild populations, and they may undergo artificial selection if maintained ex situ for multiple generations.

Captive breeding

Captive breeding is the process of maintaining plants or animals in controlled environments, such as wildlife reserves, zoos, botanic gardens, and other conservation facilities. It is sometimes employed to help species that are being threatened by human activities such as habitat loss, fragmentation, over hunting or fishing, pollution, predation, disease, and parasitism. In some cases a captive breeding program can save a species from extinction, but for success, breeders must consider many factors—including genetic, ecological, behavioral, and ethical issues. Most successful attempts involve the cooperation and coordination of many institutions.

Marius (giraffe) giraffe living at Copenhagen Zoo

Marius was a young male giraffe living at Copenhagen Zoo. Though healthy, he was genetically unsuitable for future breeding, as his genes were overrepresented in the captive population, so it was decided by the zoo authorities to kill him. Despite several offers to adopt Marius, which went against zoo policy of selling to private owners, and an online petition to save him, he was killed on 9 February 2014. His body was then dissected and necropsied in a public educational class and he was then fed to the zoo's lions. The event received worldwide media coverage and generated responses from several organisations and individuals, including death threats to staff at the zoo.
