Stock description
While the Northern Territory olive ridley turtle stock is relatively small and has a limited geographic range, it is likely that the Northern Territory has the most significant olive ridley population remaining in the Asia-Pacific region (Groom et al. 2017, in press). This stock is co-managed by the Northern Territory Government and the Dhimurru, Djelk, Laynhapuy, Anindilyakwa, Yanyuwa (Li-Anthawirriyarra) communities. These Indigenous communities have Indigenous Protected Areas in the region and nesting on the Cobourg Peninsula is provided protection within the Garig Gunak Barlu National Park. A lack of long-term monitoring has precluded stock status estimates. Many Indigenous ranger groups are now monitoring nesting in their local areas as part of land and sea management activities.
Large numbers of olive ridley turtles are reported drowned each year in ghost nets that have washed up in the Northern Territory[256]. Historically, olive ridley turtles are
