Increasing numbers of animal and plant species are becoming rare, or even extinct in the wild. In an attempt to re-establish populations, species can – in some instances – be re-introduced into an area, either through translocation from existing wild populations, or by re-introducing captive-bred animals or artificially propagated plants.
Erica von Essen and Michael Allen, using Donaldson and Kymlicka's political animal categories framework, assert that wildness standards imposed on animals are arbitrary and inconsistent with the premise that wild animals should be granted sovereignty over the territories that they inhabit and the right to make decisions about their own lives.

Reinforcement is the deliberate introduction and integration of an organism into an area where its species is already established. [1] This mode of translocation is implemented in populations whose numbers have dropped below critical levels, become dangerously inbred, or who need artificial immigration to maintain genetic diversity.

The Pyrenean ibex, also known as the bouquetin (French) and bucardo (Spanish), is the only animal to have survived de-extinction past birth through cloning. De-extinction (also known as resurrection biology , or species revivalism ) is the process of generating an organism that either resembles or is an extinct species . [ 1 ]
Animal species can be preserved in genebanks, which consist of cryogenic facilities used to store living sperm, eggs, or embryos. For example, the Zoological Society of San Diego has established a " frozen zoo " to store such samples using cryopreservation techniques from more than 355 species, including mammals, reptiles, and birds.
Possible animals for reintroduction The Bolson tortoise, the first proposed candidate for Pleistocene rewilding. The Chacoan peccary The Mustang The Burro The Dromedary The mountain tapir The capybara Asian elephant, the closest relative of the extinct mammoth .
The health of a reintroduced species impacts humans and domesticated animals, and other wildlife. Health assessments should take place before and regularly after its reintroduction. In unplanned releases or escapes, it is difficult to produce a health baseline of a species. [11]
