However, these approaches suffer from the following disadvantages: (i) Sophisticated facilities are required (particularly for freeze preservation and DNA cloning), (ii) They demand a greater skill in handling and maintenance than the conventional techniques, The flora and fauna live in natural habitats without human interference. Among the advantages are: As the very concept of sustainability indicates, environmental conservation is important so that the next generations have resources for their maintenance and subsistence. Acorns of oaks are recalcitrant and it is believed that so are the

The animals are offered a longer time and breeding activity. Seed storage conservation ; Collection of seed samples at one location and their transfer to a gene bank . This is a more discreet method than simply keeping the species away from their natural setting. Conservation of wildlife, both ex-situ and in-situ is important for the ecosystem. Such collections are expensive to maintain, are susceptible to environmental changes, and do not present a safe long-term option. The interrelationships between conservation and sustainable use are considered as well as the impact of the development of the discipline of conservation biology, the effects of the general. 3.

Created by: Abi_xx; Created on: 01-07-16 13:23; Ex Situ Conservation . the subject of captive breeding programmes. In ex-situ conservation, the biodiversity is conserved out of their natural habitats. The key difference between in-situ and ex-situ conservation is that the in-situ conservation is the conservation method that involves the conservation of species in their usual habitats while the ex-situ conservation is the conservation methods that involves species conservation elsewhere outside the natural habitat. In-situ conservation provides the required green cover and its associated benefits to our environment. Ex situ conservation measures should support in-situ conservation measures (in-situ conservation should be the primary objective). The wild life which we painstakingly breed and is no longer exactly the same which it would have been if allowed to continue in nature. We do not have provisions, space, funds and man-power to keep the required number of individuals of each species. The degree to which humans control or modify the natural dynamics of the managed population varies widely, and this may include alteration of living environments, reproductive patterns, access to resources, and protection from predation and mortality. Zoos, aquariums and botanical gardens are examples of places where it occurs. USA Threatened plants and animals can be protected and given special cases.
