Extinct in the wild

The extinction of wild (EW) species is a species classified by the International Conservation Union for Nature and is known only to organized civil members or naturalized populations outside their historic range because of the loss of many habitats . [1]

Hawaiian crows or 'aalalā (wild extinct since 2002) (released in the wild.IUCN may be downgraded in the wild if the group maintains long-term viability)

Scimitar antelope (wild and extinct since 1998) A small number of cattle have been safely released in Chad in 2016. If the group maintains long-term viability, IUCN is from wild It is extremely dangerous)

Wyoming State (It has been thought that it is extinct in the wild since 1991, but nearly 900 years have been released to the wild since then, IUCN expects to downgrade their state from wild extinction)

On the Pinta island tortoise (Geochelone nigra abingdoni) there is one living individual, Lonesome George, who died in June 2012. It was thought that the turtle was completely extinct until the middle of 2071, 1 December 1971, and the fanatic fanist Joseph Vagvugi of Hungary discovered Lonsam George at Pinta of Gallopagos. Since then, Lonesome George has become a powerful symbol of protection. Especially the Galapagos Islands. As he died on June 24, 2012, the variant was considered to be extinct again. Since 17 types of mixed pinnacle turtle were found near Wolff Volcano, a plan was made to attempt to breed the subspecies and return it to a pure state. [6]

Not all species that are extinct in the wild are rare. For example, Ameca splendens were extinct in the wild, but for some time it was a popular fish among aquarists, but recently the population of enthusiasts has declined considerably and survival is at risk. [8] However, the ultimate goal of protecting biodiversity is to maintain ecological functions. If the species exists only under the breeding, it is ecologically extinct

Reintroduction is the relocation from the captivity or from other areas where the species survives, deliberate release of species to the wild. For species that are in danger of extinction or are wild and extinct, this may be an option. However, even if their natural habitat is restored, it may be difficult to reintroduce the EW species in the wild as the survival techniques passed to the offspring often from parents may be lost during child rearing I do not think so. Conservation efforts may preserve the specific genetic factors of the species, but the seeds never fully recover as the natural meme of the species is lost.

An example of successful reintroduction of electronic warfare is the Przewalski horse, which was regarded as an endangered species in 2018 after being reintroduced in the 1990s. [9]

The species is wild and extinct if it grows only in a plant (plant), raised (animal), or a population that far exceeds its established range. Seeds are classified as wild endangered species only if they have failed to record an individual at their habitat or expected habitat as a result of years of investigation. Orix danma is a long horse duck. That range extends all over North Africa. Horny antelope is classified as extinct in the wild as one of the most recently identified was in 1988. Hunting and loss of habitat including competition with livestock are the main cause of extinction of the wild antelope population.

Not all species that are extinct in the wild are rare. For example, the Ameca splendens were extinct in the wild, but for the time being the most popular fish among aquarists, but the population of amateurs recently endangered their survival endangered a lot. But the ultimate goal of protecting biodiversity is to maintain ecological functions. If seed exists only under breeding, it is ecologically extinct. Reintroduction is the relocation from the captivity or from other areas where the species survives, deliberate release of species to the wild. For species that are in danger of extinction or are wild and extinct, this may be an option. However, even if their natural habitat is restored, it may be difficult to reintroduce the EW species in the wild, as survival techniques passed down from parent to descendant often may be lost during child rearing I do not think so.
