They are the most publicly visited ex situ conservation sites, with the WZCS (World Zoo Conservation Strategy) estimating that the 1,100 organized zoos in the world receive more than 600 million visitors annually. Globally there is an estimated total of 2,107 aquaria and zoos in 125 countries.
in situ, which consists in managing populations on-site, dynamically evolving in their natural environment. [6] [7] In situ methodologies include: conservation in natural populations (in nature) on farm conservation; ex situ, which consists in conserving individuals or populations out of their natural environments. Ex situ gene bank ...
The main objectives of the park are ex-situ conservation of endangered species, wildlife education, and research for wildlife conservation and management. [5] The zoo aims to maintain a viable and healthy population of animals in naturalistic enclosures while facilitating public visitation. [16]
For live cells/tissues, germplasm resources can be stored ex situ in seed banks, botanic gardens, or through cryopreservation. Cryopreservation is the process of storing germplasm at very low temperatures, such as liquid nitrogen. [5] This process ensures that cells do not degrade and keeps the germplasm intact.
Cryoconservation is an ex situ conservation strategy that often coexists alongside in situ conservation to protect and preserve livestock genetics. [5] Cryoconservation of livestock genetic resources is primarily done in order to preserve the genetics of populations of interest, such as indigenous breeds, also known as local or minor breeds.

In-situ conservation involves protecting or restoring the habitat. Ex-situ conservation, on the other hand, involves protection outside of an organism's natural habitat, such as on reservations or in gene banks, in circumstances where viable populations may not be present in the natural habitat. [84]
Captive breeding, or ex-situ conservation, has been used in a number of instances to save species from extinction. The principle is to create a viable population of a species in either zoos or breeding facilities, for later reintroduction back into the wild. As such a captive population can either serve as an insurance against the species going ...
