What are the different methods used to help restore the dwindling population of some endangered species?
Answer… Captive breeding, gene banks and translocation programmes are different methods followed to save the endangered species from extinction. Although expensive and seen as short-term repairs, these methods have contributed to the efforts to save the endangered species. Breeding in captivity is usually done in zoos and specialised animal clinics, under expert supervision. Captive breeding has saved Giant Pandas and Golden Lion Tamarins from extinction. Genetic diversity can be preserved through various techniques. One of these is the gene bank method, where the sperm of a species can be stored in dry, low-temperature, vacuum containers (cryogenic storage). Translocation involves the movement of a species from its natural site to a proposed reserve site. Researchers must have comprehensive life history data from wild populations to predict the long-term effects of management strategies of such a translocation before they are implemented.
