The efficient conservation and judicious use of plant genetic resources and related traditional knowledge is vital for food, health, and nutritional security plant genetic diversity available in gene banks, in the wild, and in farmer’s fields is crucial resource for food, health, and nutritional. Abstract biodiversity encompasses variety and variability of all forms of life on earth that play a great role in human existence its conservation embraces maintenance, sustainable utilization, and restoration, of the lost and degraded biodiversity through two basic and complementary strategies called in situ and ex situex situ conservation is the technique of conservation of all levels of. The biodiversity in our country is unique in nature and its in-situ and ex-situ conservation is very well needed in recent years, the global demand of herbs has led to a quantum jump in volume of medicinal plants traded within and across the countries.
Plant genetic diversity can also be preserved ex situ through the use of seed banks seeds are small but tough and have evolved to survive all manner of adverse conditions and a host of attackers seeds are small but tough and have evolved to survive all manner of adverse conditions and a host of attackers. Conservation in-situ in-situ humans are directly responsible for the decline in population numbers of thousands of species what roles it fills in the ecosystem and how it is threatened by human activityhtml conservation biology while ecology is a broad fieldjamaicachm or on-site. The conservation of plant species in situ is a complex and multifaceted procedure which involves both the maintenance and management of protected areas and actions targeted at the species and population level most effort has been aimed so far at the occurrence and persistence of species in. The ex-situ & in-situ conservation of medicinal plants in west bengal is a great step towards the conservation of not only medicinal plants but also for a large number of other species the.

Long-term aims of in situ conservation of cwr the main general aim and long-term goal of in situ conservation of target species is to ensure their survival,evolution and adaptation to changing environmental condi- tions such as global warming,changed rainfall patterns,acid rain and habitat loss.

The ex-situ conservation involves preservation and breeding of endangered species under partially or fully controlled conditions in the event of a rapid decline in the numbers of a species, due to environmental or genetic factors, ex-situ conservation serves as an ideal option. Exsitu and insitu conservation of medicinal plants essay sample india ranks sixth under world’s twelve mega bio-diversity zones out of these, two ofthem exist in our country. Ex-situ ('off site', 'out of place') conservation is a set of conservation techniques involving the transfer of a target species away from its native habitat to a place of safety, such as a zoological garden, botanical garden or seed bank.
In situ conservation of species contrasts with ex situ conservation – in seed banks, field gene banks, in botanic gardens, cryopreservation, cell/tissue culture – which has been the main conservation approach played in the agricultural sector in which in situ conservation. 1 ex-situ and in-situ conservation of medicinal plants with particular reference to jammu and kashmir state javed iqbal punjoo (ifs) (conservator of forests, south circle, j&k forest department. Conservations of biodiversity: in-situ conservation and ex-situ conservation conservation is the protection, preservation, management, or restoration of wildlife and natural resources such as forests and water through the conservation of biodiversity and the survival of many species and habitats. Ex situ conservation is the conservation and maintenance of samples of living organisms outside their natural habitat, in the form of whole plants, seed, pollen, vegetative propagules, tissue or cell cultures.
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 teagan species. In situ conservation of wild plant species a critical global review of good practices by the first author, of existing guidelines, methodologies, case studies and other relevant literature on the in situ conservation of plant species, in situ conservation will need to be complemented by ex situ conservation where appropriate and,. In-situ conservation of biodiversity and protected areas although viable populations of some organisms can be maintained ex-situ either under cultivation or in captivity, these methods are far less effective than in-situ methods, and, generally, they are extremely costly. In situ conservation in situ means on site, so in situ conservation is the conservation of species diversity within normal and natural habitats and ecosystems(by comparison, ex situ conservation focuses on safeguarding species by keeping them in places such as seed banks or living collections) because our natural systems face many threats, conserving them is not easy, and must use many.

Ex-situ conservation of medicinal plants is a complementary action to conserve the genetic diversity, thereby reducing pressure on wild habitats and augmenting raw material availability for many species of medicinal plants their wild population is on critical level and it is not suitable for dealing in-situ conservation action.
This study presents the results of our research on in situ and ex situ conservation of eight rare and valuable high-mountain medicinal plants the object of our investigations are endemics, critically endangered and endangered species according to iucn (2001) - alchemilla jumrukczalica, a achtarowii, a mollis, sideritis scardica, gentiana lutea ssp symphyandra, ribes nigrum, rhodiola rosea.
