Rekawa: A Global Turtle Research Hotspot
Rekawa Beach, located on Sri Lanka's southern coast, hosts one of the Indian Ocean's most important nesting populations of olive ridley sea turtles, with smaller populations of green and hawksbill turtles. The beach has been the subject of long-term research since the 1980s, making it one of the best-documented turtle populations in the region and an ideal site for researchers seeking to build on decades of baseline data.
Research Opportunities at Rekawa
Nesting ecology and reproductive biology:
- Nesting frequency, clutch size variation, and reproductive output across seasons
- Sand temperature effects on sex determination and embryonic development
- Nest success rates and predation dynamics by monitor lizards, crabs, and feral dogs
- Hatchling emergence patterns and orientation behavior
- Tagging programs for long-term population tracking and dispersal studies
Genetic and genomic research:
- Population genetics to assess genetic diversity and gene flow within and between nesting populations
- Parentage analysis to document multiple paternity and reproductive success variation
- Genomic approaches to disease detection and immune function assessment
Human interaction and conservation:
- Fishing pressure documentation including net entanglement and bycatch
- Effectiveness of conservation interventions (nest protection, hatchery programs)
- Community attitudes and engagement in turtle conservation
Logistics and Field Access
Rekawa Beach is 25 kilometers from Daro's Enclave. The beach is managed by the Rekawa Lagoon Sanctuary Foundation, an established research organization that facilitates scientific work and can provide guidance, field assistants, and accommodation. Most researchers combine independent research activities with collaboration with this established program.
Nesting activity occurs year-round, with peaks in monsoon transition periods (March-April and October-November). Night surveys for nesting turtles and hatchling emergence documentation are standard research methods.
Seasonal Calendar
Year-round nesting: Unlike temperate populations, tropical sea turtles at Rekawa nest throughout the year. Nesting peaks during warmer months, while winter months show lower activity.
Optimal research months: March-May and September-November offer high nesting activity combined with favorable weather for field work.
Integration with Daro's Enclave
Research residency at Daro's Enclave provides a home base for extended Rekawa studies. The villa's fiber internet enables real-time data backup and remote collaboration with advisors. The quiet environment supports analysis work during non-survey hours. Most turtle researchers spend mornings at Rekawa and afternoons analyzing data or conducting literature review at Daro's Enclave.
Getting Started with Turtle Research
Rekawa welcomes independent researchers and research teams. Prior experience with sea turtle monitoring is advantageous but not required. Most research involves systematic field observation, tissue sampling, and careful data recording. Contact the research residency program to discuss your research questions and find the right fit.
