The line graph gives information about how many of four types of turtles resided in India over a 32-year period.
It is clear that turtles of all breeds were in similar numbers at the beginning of the period. Through the years, Leatherback and Green turtles’ populations dwindled, with the former going down remarkably, while All other Species increased in number slightly, except for Olive Ridley turtles whose number jumped noticeably.
In 1980, every turtle breed started with 100 specimens. All figures fluctuated wildly from then on, and in 1998, turtles of the Olive Ridley type gradually reached around 140 individuals, while all species remained practically the same in number. Coming to the end of the period, the number of Olive Ridleys bumped up significantly in comparison to the initial number, making up slightly over 130 units, and All Species witnessed a marginal increase to 110 members.
In 1998, Green and Leatherback turtles’ colonies saw some shrinking, with the former falling to 95 turtles and the latter to just under 70. In the following years, the downward trend continued for both kinds. So, in 2012, only 90 Green turtles remained when there were only about 60 Leatherbacks in existence.
