Olive Ridley Turtles' Mass Nesting: Science and Conservation
Olive Ridley turtles gather in large groups to lay eggs, a process called arribada.
They return to the same beaches where they were born, guided by a sort of map of the earth's magnetic field.
While populations have been growing, human actions, such as artificial incubation of eggs, are helping to increase their numbers.
However, overcrowding and temperature changes are becoming concerns.
It's vital to protect nesting sites and balance tourism with the need to safeguard these turtles.
The community has an important role in guarding the nests and helping conservationists.
Olive Ridley turtles are known for mass nesting events called arribadas.
A record seven lakh turtles nested at Odisha's Rushikulya beach in March.
These turtles have a geomagnetic map imprinted at their nesting sites and return with remarkable precision.
Human interventions like artificial incubation of eggs have helped boost turtle populations.
Tourism and human interaction can stress the turtles and disrupt their nesting behavior.
