(IELTS graph) Population of turtles in India - EssayForum
The authors compared their findings with other similar analysis done on other populations and breeds of turtles, and found that their findings were mostly consistent with those by others: an increase in the adult and juvenile stages would prove the most beneficial to the population of turtles. The authors then proposed many conservation techniques that would benefit this spotted turtle population the most. Many of these proposed solutions have problems, and the authors note this. The first conservation technique proposed by the authors was to simply protect the habitat of adult and juvenile spotted turtles. Since the habitat of juveniles is not fully understood, this would prove to be difficult. The second proposed conservation method describes “headstarting”. This involves capturing eggs and raising the turtles until they reach maturity. Since a spotted turtle does not reach maturity until age twelve, this method would be very costly, and may not even work. The last protection method proposed is to protect the turtle eggs. Unfortunately, the spotted turtle nests are very hard to find, so this method would also be hard to implement. Though the proposed protection methods seem unreasonable, the authors were able to recognize the life stages at which the spotted turtle is most vulnerable to increases or decreases in the population. Using stage-classified matrices, researchers can learn more about where to focus conservation efforts in order to save populations and species at risk of extinction.
Why has the population of turtles decreased? | Yahoo Answers
The population of turtles in the Hawaiian islands is increasing at ca
The breeding population of Green Turtles here is about 100 females, nesting in the Lara/Toxeftra area mainly (105 females have been tagged so far). The Loggerhead population is somewhat larger and is now estimated at over 500 females. Turtles are tagged and their reappearance on the nesting beaches (and in the nets of fishermen around the Mediterranean) is recorded. The number of nests found each year on our beaches is also an indication of the size of populations and of trends.

Exploitation of turtles in the Mediterranean, from the 1920s to the 1970s, has decimated turtle populations. Tens of thousands of turtles, mainly green turtles, were shipped from the north-eastern Mediterranean, to Egypt, where there was a market for them, and to Europe where there was great demand for turtle soup. The intensive use of beaches, for tourism and recreational purposes, is now threatening turtles in the Mediterranean by depriving them of their nesting grounds. Many turtles also drown or are killed when caught in fishermen's nets or on long lines. Turtles and especially the Green turtles are, as a result, on the verge of extinction in the Mediterranean. It is tentatively estimated that the current annual nesting population of turtles is about 500 female Green turtles and about 3,000-5,000 Loggerheads.
