Term Ex-situ conservation
Definition

The conservation of biodiversity components outside of their natural habitats. Some examples are the preservation of living genes or genotypes of species through live plant collections in botanical gardens, or the collection of plant or animal tissues in frozen chambers in scientific laboratories. Other examples include zoos, seed banks, collections of pollen and herbariums in natural history museums.

Ex situ conservation is used to protect everything from wild species and regressive forms, to cultivated species. When applied to domesticated species, ex-situ conservation aims to preserve, outside of its place of origin or diversity, not only the species but also the variations produced during its evolutionary process of domestication. This type of conservation has been widely used in recent decades.

At present, the Dominican Republic is developing several ex-situ conservation programs, launched mainly by institutions under the Ministry of Environment like the Botanic Gardens and the National Zoo.

The National Botanic Garden has a program of mass production in its greenhouse, where it reproduces native and endemic forest specimens for reforestation, sponsored by state and private institutions. The botany department also runs breeding programs for endangered plants, some of which in critical danger of extinction. Table E-1 shows some of the species that have been reproduced successfully in the National Botanic Garden. 1

The Dominican zoo also has an ex-situ conservation program dedicated to the captive breeding of native and endemic species. Among the species are Caribbean flamingos (Phoenicopterus ruber ruber), the antillean yaguaza (Dendrocygna arborea), the ricordi iguana (Cyclura ricordii), the rhinoceros iguana (Cyclura cornuta), the partridge poop (Geotrygon leucometopia), the white collar row (Corvus leucognaphalus) and the solenodonte (Solenodon paradoxus). 1
