T he focus then shifted to the creation of a biosecure area for the leaf-toed gecko, a species unique to Barbados. Connor Blades (UWI MPhil 2020) presented insights into the gecko’s limited distribution and the fencing measures implemented to protect it from invasive threats. Biologist Dr. Darren Browne took the audience on a journey into the world of flatworms, emphasising the ongoing citizen science project’s collaboration with governmental bodies. His research highlighted the dangers posed by these worms to earthworms, essential for maintaining healthy soil structure and supporting food production. Dr. Browne cautioned against the potential spread of flatworms through the movement of topsoil. Ecologist Dr. Henri Vallès navigated the waters to discuss the GEF (Global Environment Facility)-funded pilot projects on marine invasives, focusing on the much- feared lionfish. Contrary to expectations, research indicated no negative impact on native fishing communities or fish catches in Barbados. Dr. Vallès recommended continued targeting of lionfish by commercial and recreational spear-fishers to maintain ecological balance. The discussion concluded with insights into sun corals, introduced to the Caribbean in the 1950s. Dr. Vallès and his graduate student Robert Bourne , conducted a coast-wide survey, revealing the presence of sun corals on artificial structures. A sun coral removal experiment suggested that manual removal could be a cost-effective measure to control sun coral abundance on these structures. The UWI. Cave Hill scientists’ dedication to combating invasive species reflects a commitment to environmental sustainability and underscores the university’s role as a key player in Barbados’s conservation efforts.
