Conclusions
- nesting season
Only seven turtles nested at Cook's Islet
during the twenty-five-night survey, and few turtles crawled at
the other islets, indicating an alarmingly low number of breeding
turtles in the nesting season. These results are corroborated
by Palmerston fishermen, all of whom
commented on the paucity of turtles this season. Ongoing tracking
of the satellite-tagged turtle will provide insight into the migratory
habits of Palmerston turtles, as
will genetic analyses.
Given
such low reproductive potential, the annual turtle harvest (5
to 8 turtles last season) could seriously jeopardize the population's
survival. Turtles can be an important resource for the future
of Palmerston, both as a link to Palmerston's rich heritage through
low-level harvesting and as a catalyst for sustainable development
through ecotourism. However, only careful management based on
scientific research can ensure the turtles' welfare. This survey,
if carried out each year, will enable the Palmerston community
to monitor turtle nesting trends and to set sustainable harvesting
quotas.
