how to write a reference on endangered species of plants in India
Answers
Explanation:
Extinction and species introduction are two major biodiversity crises of the current millennium. A species may become endangered and eventually extinct when death rate exceeds birth for a prolonged duration. The reasons may be natural or anthropogenic. Anthropogenic activities are now-a-days prominent and causing extinction of many plant species of ecological and economic significance. Many species are facing tremendous pressure and are on the verge of extinction in Northeast India, one of the global biodiversity hotspots in the world. In the present communication, we present the population status and conservation requirement of three rare/endangered and endemic plant species of the region viz. Aquilaria malaccensis, Gleditsia assamica and Gymnocladus assamicus. Natural populations of A. malaccensis have been depleted due to over-harvesting of mature trees for its precious 'agarwood'. However, plantations have been established in home-gardens of upper Assam and serving as a means of ex-situ of conservation of the species. The G. assamica and G. assamicus populations are also very poor in nature which culminates with poor natural regeneration. Therefore, a similar way of ex-situ conservation in plantations as practiced in A. malaccensis is suggested for effective conservation of the species.
