What you think why UK government has created law to protect bat habitats? Why any individual buying land or making construction work needs to submit the report of bat survey conducted by the expert ecology consultants? There are severe reasons because of which the government has taken such legal steps in protection of bat population. In 1970, the sudden decline of bat population get started and by 1980 more than 70% bat habitats were destroyed.

In Britain, a team of ecology consultants conduct survey in 1980 and the figures came out which were very surprising and serious for the government. It is known that bats eat flying pest thus a decline in bat population will make a long term impact on the ecological system and most importantly o agricultural system. Absence of any species in ecological system can affect all other species or creatures on earth. Thus, it is necessary to maintain the ecological system by protecting bats by law.

Bats hold high agricultural value as even a little brown bat (as little as our thumb) eat 4 to 8 grams of insects each night. Human life is greatly depended on the agricultural and ecological system. Thus, many national and international agencies have started conducting bat survey and take actions to save this endangered species. Survey needs to be done by the environmental scientists who have detailed understanding of the ecological issues.

Area in which the team of ecological scientists conduct survey is known as the project site or area under survey. Once area is decided, the scientists find the existence of bat roosts or bat habitats in various places. They use the latest instruments and indicators to find bats existence. Sometimes effective mitigation schemes are applied to save bat habitats. Bat survey is conducted seasonally and recent survey says that because of the legislation of bat protection, the decline of bats population is decreased to a great extent.
