In situ conservation


In situ conservation

In situ conservation is 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. 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. It is applied to conservation of agricultural biodiversity in agroecosystems by farmers, especially those using unconventional farming practices.

Around 4% of the total geographical area of the country is used for in situ conservation.The following methods are presently used for insitu conservation.It is the best method for the following term protection of biodiversity.

In-situ conservation Numbers available
Biosphere Reserves 7
National Parks 80
Wild-life Sanctuaries 420
Botanical gardens 120

Biosphere reserves

Biosphere reserves cover large area,more than 5000 sq. km. It is used to protect species for long time.

Name of Biosphere State
Nanda Devi Uttrakhand
Nokrek Meghalaya
Manas Assam
Sunderbans West Bengal

National Park

A National Park is an area dedicated for the conservation of wild life along with its environment. It is usually a small reserves covering an area of about 100 to 500 sq. kms. within the biosphere reserves, one or more national parks are also exists.

Name Of National Park State Important wildlife
Kaziranga Assam One Horned Rhino
Gir National Park Gujarat Indian Lion
Bandipur Karnataka Elephant
Dachigam J & K Hangul
Kanha M.P Tiger
Periyar Kerala Tiger, Elephant

Wild Sanctuaries

A wild sanctuary is an area, which is reserved for the conservation of animals only. At present, there are 492 wild sanctuaries in our sanctuaries

Name of sanctuary State Major wild Life
Hazaribagh sanctuary Bihar Tiger, Leopard
Ghana Bird sanctuary Rajasthan 300 Species of Birds
Sultanpur Bird Sanctuary Haryana Migratory Birds
Abohar Wild life Sanctuary Punjab Black Buck
Nal sarovar Bird Sanctuary Gujarat Water Birds
Mudumalai Wild life Sanctuary Tamil Nadu Tiger,Elephant,Leopard
Vedanthangal Bird Sanctuary Tamil Nadu Water Birds

Gene Sanctuary

A Gene sanctuary is an area,where the plants are conserved.


One benefit of 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. The species gets adjusted to the natural disasters like drought,floods,forest fires and this method is very cheap and convenient method


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.


In agriculture, in situ conservation techniques are an effective way to improve, maintain, and use traditional or native varieties of agricultural crops. Such methodologies link the positive output of scientific research with farmers' experience and field work.

First, the accessions of a variety stored at a germplasm bank and those of the same variety multiplied by farmers are jointly tested in the producers field and in the laboratory, under different situations and stresses. Thus, the scientific knowledge about the production characteristics of the native varieties is enhanced. Later, the best tested accessions are crossed, mixed, and multiplied under replicable situations. At last, these improved accessions are supplied to the producers. Thus, farmers are enabled to crop improved selections of their own varieties, instead of being lured to substitute their own varieties with commercial ones or to abandon their crop. This technique of conservation of agricultural biodiversity is more successful in marginal areas, where commercial varieties are not expedient, due to climate and soil fertility constraints. Or where the taste and cooking characteristics of traditional varieties compensate for their lower yields.[1]
