There are currently two monitored survey areas on Gnaraloo: the Gnaraloo Bay Rookery and the Gnaraloo Cape Farquhar Rookery which are both located in the southern section of the Ningaloo Marine Park. Sea turtle species which been recorded as nesting in these rookeries include endangered loggerhead (Caretta caretta), endangered green (Chelonia mydas) and possibly critically endangered hawksbill (Eretmochelys imbricata) turtles. Loggerheads are the dominant nesting species in both rookeries.
The Gnaraloo Bay Rookery is a significant mainland (as opposed to island) nesting rookery for loggerheads in Western Australia.
The first ever on-ground reconnaissance surveys of the Gnaraloo Cape Farquhar Rookery were undertaken during 2011/12 after aerial surveys conducted by the GTCP during 2009/10 and 2010/11. The on-ground surveys recorded the majority of nesting activities as loggerheads, but green turtles also used the rookery for nesting purposes. The majority of research questions concerning the Gnaraloo Cape Farquhar Rookery cannot yet be answered, including: (1) the seasonal number of turtle nests at the rookery; (2) the start, peak and end of the turtle nesting period at the rookery; and (3) the relationship, if any, between the Gnaraloo Bay Rookery and the Gnaraloo Cape Farquhar Rookery as it is possible that sea turtles use both locations for mating, nesting, foraging and/or resting purposes.
The research and data collected by the GTCP are provided to Government agencies (State and Australian) who are responsible for decision-making on environmental protection and conservation, universities (country wide), sea turtle experts and made publicly available.
