This initial consortium was expanded to include a large number of organisations across the Overseas Territories. TCOT Final Report: Section 6 Page 2 6.

Summary and Recommendations Additionally, we make a major overarching recommendation to the UK Government to support the Summary conservation and management of marine biodiversity At least three species of marine turtle (leatherback, green in the UK OTs under the Environment Charters. and hawksbill turtles) nest in the British Virgin Islands (BVI) but in critically low numbers (see table 6.1). Although there The Overseas Territories of the UK have long been may have been a modest recovery of some species in recent acknowledged as being rich in biodiversity (Proctor & years, much needs to be done to ensure the continued Fleming 1999). The small islands or island archipelagos existence of marine turtles nesting in the BVI and facilitate of the Caribbean UK Overseas Territories currently their recovery. Foraging marine turtles (generally green do not or are unable to carry out sufficient monitoring, and hawksbill turtles) are widespread in BVI coastal waters research, management and educational outreach required of the BVI and, based on preliminary work carried out as to ensure the sustainability of their marine and coastal a result of TCOT, appear to be locally abundant at some natural resources. TCOT strongly recommends that the sites, despite having been subject to direct exploitation for UK Government further contributes to marine biodiversity a long period of time. Direct exploitation still occurs at levels conservation and management in the UK Overseas much reduced from the recent past but we estimate that Territories through provision of funding and expertise >150 green turtles and >50 hawksbills are likely taken per under the FCO/DfID Overseas Territories Environment year in a directed fishing effort. Programme (OTEP), Defra’s Darwin Initiative and through the provision of bespoke scholarships for tertiary education TCOT recommends that the Government of the British in biodiversity/conservation related subjects for citizens of Virgin Islands takes all necessary steps to ensure the the OTs.
