Olive ridley sea turtle

The Olive ridley sea turtle (Lepidochelys olivacea) is a member of the Testudines order and the Cheloniidae family. While recognized primarily as a marine species, its nesting habits create unique challenges for agriculture in tropical coastal zones, where farming activities often intersect with the turtles' reproductive cycles.

The primary crops affected by the presence of these turtles include coastal coconut plantations, vegetable garden patches, and nursery seedlings planted near sand dunes. Since these turtles occupy sandy soils to lay their eggs, any agricultural venture located in these specific coastal micro-habitats risks physical disturbance during the nesting season.

The biology of the species is defined by the phenomenon of mass nesting or "arribada." During this period, thousands of individuals emerge from the sea to lay eggs. This massive movement across coastal soil leads to significant mechanical disturbance of the substrate, which directly threatens the integrity of cultivated land and the health of the plants growing within the nesting radius.

The damage caused is primarily mechanical: digging nesting pits disrupts the root zones of established plants and buries young seedlings. Furthermore, the constant tramping and compacting of the soil by the turtles result in a loss of soil structure, which hinders root development and reduces the overall yield of the affected agricultural plots.

Managing the impact of Olive ridley sea turtles requires a balance between environmental conservation and farming interests. Recommended protective measures include the implementation of physical barriers such as fencing, the strategic scheduling of planting cycles to avoid peak nesting months, and the deployment of non-lethal deterrents to guide nesting activity toward non-cultivated beach sectors.
