Gahirmatha arribada beach are most dynamic and eroding at a faster rate over the years from 2008-09 to 2010-11, especially during the turtles breeding seasons. Impact of armouring cement tetrapod on olive ridley sea turtle nesting beach at Gahirmatha rookery of Odisha coast has also been reported in this study. This study documented the area of nesting beach has reduced from 0.07 km2to 0.06 km2. Due to a constraint of nesting space, turtles were forced to nest in the gap of cement tetrapods adjacent to the arribada beach and get entangled there, resulting into either injury or death. A total of 209 and 24 turtles were reported to be injured and dead due to placement of cement tetrapods in their nesting beach during 2008-09 and
2010-11 respectively. Olive ridley turtles in Odisha are now exposed to many problems other than fishing related casualty and precautionary measures need to be taken by the wildlife and forest authorities to safeguard the Olive ridleys and their nesting habitat at Gahirmatha.
