The Wollemi pine is another example of a plant that is being preserved via ex situ conservation, as they are being grown in nurseries to be sold to the general public. The Orange-bellied parrot , with a wild population of 14 birds as of early February 2017, [ 15 ] are being bred in a captive breeding program.
Genetic resources of several important timber, fruit and other non-timber tree species are conserved ex situ in genebanks or maintained in field collections. Nevertheless, in situ conservation in forests and on farms is in the case of most tree species the most important measure to protect their genetic resources. [citation needed]
For example, whilst ex situ conservation protects CWR (or more correctly, their genes) from threats in the wild, it can limit evolution and adaptation to new environmental challenges. In 2016, 29% of wild relative plant species were completely missing from the world’s genebanks, with a further 24% represented by fewer than 10 samples.
Ex situ conservation is defined as the “conservation of components of biological diversity outside their natural habitats.” [50] Ex situ conservation is the conservation of genetic resources (species, varieties, cultivars, sub-species, landraces etc.) for food and agriculture outside their natural habitat, in a managed environment including ...
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.
In-situ conservation is the on-site conservation or the conservation of genetic resources in natural populations of plant or animal species, such as forest genetic resources in natural populations of tree species. [1] This process protects the inhabitants and ensures the sustainability of the environment and ecosystem.
In-situ conservation of seed-producing plant species is another conservation strategy. In-situ conservation involves the creation of National Parks, National Forests, and National Wildlife Refuges as a way of preserving the natural habitat of the targeted seed-producing organisms. In-situ conservation of agricultural resources is performed on-farm.
The efforts put into captive breeding can aid in education about conservation because species in captivity are closer to the public than their wild conspecifics. [6] These accomplishments from the continued breeding of species for generations in captivity is also aided by extensive research efforts ex-situ and in-situ. [6]
