Thevenard Island has been monitored by the NWSFTCP since 2016 as one of its primary monitoring sites. The island is a rookery for flatback, green, and hawksbill turtles and considered a medium density nesting site for flatbacks. Volunteers and staff conduct both tagging at night and morning track counts to assess the population of turtles nesting on the island. Once an active site for Chevron oil and gas operations, the island has now been rehabilitated to its former state, but a resort still operates on the island's eastern end.
