In situ and ex situ conservation methods

These collections are susceptible to hybridization, artificial selection, genetic drift, and disease transmission. These measures also have a valuable role to play in recovery programmes for endangered species. Some of the operations include performance recording, breeding programmes, ecosystem management at sacred groves, gene sanctuary, biodiversity hotspots, community reserves and biosphere reserves.

However, there are very controversial scientific and social problems with this approach, which was characterized by serious conflicts between local communities and the state. In part, this may be because they often lack authority over the appropriate lands.

Genetic variability also is preserved by gene bank under normal growing conditions. Integrated regional development planning IRDP is a response to the need for better integration of the numerous interests holding conflicting views of how the resources of a region are to be used Saunier, ; OAS, This includes national parks and nature reserves, sustainable use reserves, wilderness areas and heritage sites Protected areas Pas have been widely used as a conservation tool in order to maintain a representative sample of unaltered species and eco-systems for the future, and to limit the potential for environmental degradation through human mismanagement of resources.

Consultations are made through such mechanisms as public hearings, ombudspersons, or representatives of the interest groups concerned. How to Design Demonstration Projects All of this is more easily done if the region is divided into smaller homogeneous units for analysis and if partnerships are created from the variety of constituencies.

It may be set aside for the protection of biological diversity, and of natural and associated cultural resources and is managed through legal or other effective means. That interrelatedness requires that information be managed in an integrated way if we are to make fact-based decisions. 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.

For example, instead of banning hunting altogether, a series of regulations could be put in place to regulate hunting, i. Immigrants are then exchanged between the fragments to reduce inbreeding, and then the fragments are managed separately again.

Information feedback consists of formal and informal one-way presentations, newspaper articles, notices, etc. IRDP also analyzes the interactions of the region with neighboring areas.

It is less expensive and easy to manage. 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. Gene sanctuary[ edit ] A gene sanctuary is an area where plants are conserved.

It is useful for declining population of species. Later, the best tested accessions are crossed, mixed, and multiplied under replicable situations.

Due to habit destruction and unfavorable environment conditions. Other institutions such as zoos and botanical gardens are increasingly taking on roles as genetic reservoirs against extinction and captive breeding for future re-introduction programmes.

Multiple sites may be required to capture a reasonable amount of the allelic variation of a species Food and Agriculture Organization, a. In world there are about zoos. Life expectancy of Caged Ex-situ animal is less compared to its in-situ cousin.

Offsprings born in captivity, have problems in adjusting and surviving in jungles. Tiger cub born in zoo, feeding on readymade meat, living in a small area, cannot easily survive in a jungle.

Ex situ conservation is the technique of conservation of all levels of biological diversity outside their natural habitats through different techniques like zoo, captive breeding, aquarium, botanical garden, and.

Ex Situ Conservation Methods Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. This involves conservation of genetic resources, as well as wild and cultivated or species, and draws on a diverse body of techniques and facilities.

Difference between In Situ and Ex Situ Conservation

About 4% of the total geographical area of the country is used for in situ conservation. The following methods are presently used for in situ conservation.
