The status of marine turtles in Montserrat (Eastern Caribbean)

The status of marine turtles in Montserrat (Eastern Caribbean) is reviewed following five years of monitoring (1999-2003). The mean number of nests recorded during the annual nesting season (June-October) was 53 (± 24.9 SD; range: 13-43). In accordance with earlier reports, the nesting of hawksbill (Eretmochelys imbricata) and green (Chelonia mydas) turtles was confirmed on several beaches around the island. Only non-nesting emergences were documented for loggerhead turtles (Caretta caretta) and there was no evidence of nesting by leatherback turtles (Dermochelys coriacea); however, it is possible that additional survey effort would reveal low density nesting by these species. Officially reported turtle capture data for 1993-2003 suggest that a mean of 0.9 turtle per year (±1.2 SD; range: 0-4) were landed island-wide, with all harvest having occurred during the annual open season (1 October to 31 May). Informed observers believe that the harvest is significantly under-reported and that fishermen avoid declaring their catch by butchering turtles at sea (both during and outside the open season). Of concern is the fact that breeding adults are potentially included in the harvest, and that the open season partially coincides with the breeding season. The present study has shown that although Montserrat is not a major nesting site for sea turtles, it remains important on a regional basis for the Eastern Caribbean.
