Ameenpur Lake - First Biodiversity Heritage Site

Ameenpur Lake gets the status of the first Biodiversity Heritage Site in the country under the biodiversity act, 2002. it is an ancient man-made lake in a western part of Telangana. Biodiversity Heritage Site is areas of

biodiversity importance, which harbor rich biodiversity, wild relatives of crops, or areas, which lie outside the protected area network. Biodiversity Heritage sites are managed by a locally constituted Biodiversity Management Committee and get funding for its protection.

4.3. EUTROPHICATION

♤ Greek word - Eutrophia means adequate & healthy nutrition.

♤ Eutrophication is a syndrome of ecosystem, response to the addition of artificial or natural nutrients such as nitrates and phosphates through fertilizer, sewage, etc that fertilize the aquatic ecosystem.

♤ It is primarily caused by the leaching of phosphate and - or nitrate containing fertilisers from agricultural lands into lakes or rivers.

♤ The growth of green algae which we see in the lake surface layer is the physical identification of an Eutrophication.

♤ Some algae and blue-green bacteria thrive on the excess ions and a population explosion covers almost entire surface layer is known as algal bloom. This growth is unsustainable, however.

♤ As Algal Bloom covers the surface layer, it restricts the penetration of sunlight. Diffusion of gas from atom

♤ Oxygen is required by all respiring animals in the water and it is replenished by diffusion and photosynthesis of green plants.

♤ The oxygen level is already low because of the population explosion and further oxygen is taken up by microorganisms which feed off the dead algae during decomposition process.

♤ Due to reduced oxygen level, fishes and other aquatic organism suffocate and they die.

♤ The anaerobic conditions can promote growth of bacteria which produces toxins deadly to aquatic organisms, birds and mammals.

♤ All this eventually leads to degradation of aquatic ecosystem and death of its organisms.

♤ It often leads to change in animal and plant population & degradation of water & habitat quality.
