Data loggers were deployed in sea turtle nests to record incubation temperatures. Sea turtles have temperature dependent sex determination (TSD) so researchers can predict the sex of the hatchlings based on incubation temperatures. Temperatures above 32°C produce female hatchlings, temperatures below 28°C produce male hatchlings and temperatures near 29°C produce mixed ratios. For more information on the data loggers employed to monitor sea turtle hatchling gender Based on temperature predictions it appears that predominately male-biased and mixed ratio clutches are being produced on Keewaydin Island. This research is a collaborative effort among Rookery Bay NERR, The Conservancy of Southwest Florida and the University of Alabama, at Birmingham. |

Coastal Changes
Shoreline Change
Reserve staff has been using GIS technology to map the Keewaydin Island shoreline annually since 1998. This effort was initially conducted to examine the effects of Australian pine removal from the island. Results of this monitoring indicate that shoreline change in areas where Australian pines were removed was comparable to other areas where the trees were not present. The most noteworthy changes continue to occur along the south tip of the island, which is actually accreting (expanding).
The island’s shoreline is also mapped directly following major storm events to document their impacts on this dynamic coastal area.
Keewaydin Habitats
Habitats on Keewaydin Island prior to Australian pine removal (1995)
In the mid-1990’s, Reserve staff mapped the nonnative and native communities on Key Island using satellite positioning technology, and planned a massive habitat restoration. Restoration funds included more than $1 million of federal, state and private funds. In 1998, contractors were employed to cut down and burn 350 acres of Australian pine trees on Key Island and nearby Coconut Island.
As a result, Keewaydin Island has grown to provide more habitat benefiting many species, and sea turtle nesting on Key Island beaches increased significantly.
