class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Ex Situ Conservation<\/strong> is the preservation of components of biological diversity outside their natural habitats.<\/li>\n\n\n\n<li>This involves the conservation of genetic resources, as well as wild and cultivated species, and draws on a diverse body of techniques and facilities.<\/li>\n\n\n\n<li>The reintroduction of an animal or plant is a prominent example of this type of conservation method.\n<ul class=\"wp-block-list\">\n<li>For instance, Gangetic gharial has been reintroduced in the rivers of Madhya Pradesh, Uttar Pradesh and Rajasthan, where they were extinct earlier.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading has-text-color

Ex Situ Conservation of Biodiversity<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><strong>Prominent techniques and methods of ex situ type of conservation of biodiversity include:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Botanical Gardens<\/strong><\/li>\n\n\n\n<li><strong>Zoological Parks<\/strong><\/li>\n\n\n\n<li><strong>Gene Banks<\/strong><\/li>\n\n\n\n<li><strong>Seed Banks, and<\/strong><\/li>\n\n\n\n<li><strong>Cryopreservation<\/strong><\/li>\n<\/ul>\n\n\n\n<p>Each of these methods has been discussed in detail in the sections that follow.<\/p>\n\n\n\n<p><strong>Botanical Gardens<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Botanic gardens<\/strong> are institutions that hold documented collections of living plants for scientific research, conservation, display, and education.<\/li>\n\n\n\n<li>Conservation is being realised by means of seeds, cuttings, and tissue or cell cultures, and genetically representative permanent collections should be secured for conservation, (re-) introduction, research, and education.<\/li>\n<\/ul>\n\n\n\n<p><strong>Zoological Parks<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>It is a facility in which animals are housed within enclosures, displayed to the public, and in which they may also breed.<\/li>\n\n\n\n<li>The breeding of endangered species is coordinated by cooperative breeding programmes containing international study books and coordinators, who evaluate the roles of individual animals and institutions from a global or regional perspective, and there are regional programmes all over the world for the conservation of endangered species.<\/li>\n<\/ul>\n\n\n\n<p><strong>Gene Banks<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Gene Banks preserves genetic material, such as DNA, sperm, and embryos, from endangered species.<\/li>\n\n\n\n<li>These resources can be used for research, breeding programs, and potential future reintroductions.<\/li>\n<\/ul>\n\n\n\n<p><strong>Seed Banks<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Seed Banks store seeds under specific conditions to preserve genetic diversity.\n<ul class=\"wp-block-list\">\n<li>Hence, they are a type of gene bank.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>They have considerable advantages over other methods of <strong>ex situ conservation<\/strong>, such as ease of storage, the economy of space, relatively low labour demands and consequently, the capacity to maintain large samples at an economically viable cost.<\/li>\n\n\n\n<li>There are many reasons to store seeds, such as:\n<ul class=\"wp-block-list\">\n<li>To have the genes that plant breeders need to increase yield, disease resistance, drought tolerance, nutritional quality, taste, etc., of plants used in agriculture (i.e., crops or domesticated species).<\/li>\n\n\n\n<li>To forestall the loss of genetic diversity in rare or imperilled plant species in an effort to conserve biodiversity ex situ.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<p><strong>Cryopreservation<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Cryopreservation<\/strong> is a process where organelles, cells, tissues, extracellular matrix, organs or any other biological constructs susceptible to damage caused by unregulated chemical kinetics are preserved by cooling to very low temperatures (typically -80 \u00b0C using solid carbon dioxide or -196 \u00b0C using liquid nitrogen).<\/li>\n\n\n\n<li>At low enough temperatures, any enzymatic or chemical activity that might cause damage to the biological material in question is effectively stopped.<\/li>\n\n\n\n<li>It is a useful method for long-term storage of germplasm, especially for plant species that are difficult to conserve as seeds due to low desiccation tolerance.<\/li>\n\n\n\n<li>For aquatic species, it has limited application because female gametes and fertilised eggs usually cannot be frozen.<\/li>\n\n\n\n<li>For livestock, it usually means the preservation of germplasm for the purpose of genetic conservation.<\/li>\n\n\n\n<li>This distinction is more relevant for livestock than for other sectors because it is more widely applied for uses other than conservation.<\/li>\n<\/ul>\n\n\n\n<h3
