In-situ conservation


In-situ conservation

In-situ conservation means "on-site conservation". It is the process of protecting an endangered plant or animal species in its natural habitat, either by protecting or cleaning up the habitat itself, or by defending the species from predators. Increasingly, this term is also being applied to the conservation of agricultural biodiversity in agroecosystems by farmers, especially those using unconventional farming practices. One benefit to "in-situ" conservation is that it maintains recovering populations in the surrounding where they have developed their distinctive properties. Another 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.

Wildlife and livestock conservation is mostly based on "in situ" conservation. This involves the protection of wildlife habitats. Also, sufficiently large reserves are maintained to enable the target species to exist in large numbers. The population size must be sufficient to enable the necessary genetic diversity to survive within the population, so that it has a good chance of continuing to adapt and evolve over time. This reserve size can be calculated for target species by examining the population density in naturally-occurring situations. The reserves must then be protected from intrusion, or destruction by man, and against other catastrophes.
