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. [3]
Another benefit is that this strategy helps ensure the ongoing processes of evolution and adaptation within their environments. As a last resort, ex situ conservation may be used on some or all of the population, when in situ conservation is too difficult, or impossible. The species gets adjusted to the natural disasters like drought, floods ...
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. [83]
An OECM is defined by the Convention on Biological Diversity as: [A] geographically defined area other than a Protected Area, which is governed and managed in ways that achieve positive and sustained long-term outcomes for the in situ conservation of biodiversity, with associated ecosystem functions and services and where applicable, cultural, spiritual, socio–economic, and other locally ...
There are two complementary ways to conserve genetics resources: 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
Site-based conservation is an approach to nature conservation that relies on the designation of important or representative examples of sites supporting key habitats or species, such as Key Biodiversity Areas (KBAs) or Important Bird Areas (IBAs). Whilst a rational way of ensuring that the very best resources are protected, it is open to a ...
A 2019 UN report assessing global biodiversity extrapolated IUCN data to all species and estimated that 1 million species worldwide could face extinction. [38] [39] Conservation of a select species are often prioritized on several factors which include significant economic and ecological value, as well as desirability or attractiveness. [40]
Habitat conservation is a management practice that seeks to conserve, protect and restore habitats and prevent species extinction, fragmentation or reduction in range. [1] It is a priority of many groups that cannot be easily characterized in terms of any one ideology .
