Abstract

Based on the goals set forth in the Dutch Biodiversity Policy Programme, The Netherlands has a traditionally strong commitment to protect biodiversity and marine mammals both internationally and in its own national and Kingdom waters. Last year the responsible ministry, namely the Netherlands Ministry of Economic Affairs, Agriculture and Innovation (EL&I), developed a management plan for the biological resources of the recently declared Dutch Caribbean Exclusive Economic Zone. The Dutch Caribbean EEZ was formally declared on June 10, 2010, and amounts to more than 90.000 km2 of diverse tropical marine habitats. One of the key ambition coming forth from that plan was to develop a Dutch Caribbean Marine Mammal Sanctuary (MMS). This report provides the necessary review and background on which to base such an endeavour. Our updated review establishes beyond doubt that the Dutch Caribbean EEZ has a rich and diverse marine mammal fauna which merits more extensive protection. Even though the fauna is only poorly known, based almost exclusively on incidental sightings and strandings, it amounts to a minimum of 19 marine mammal species, and possibly up to more than 30. Without exception, all documented species appear on protected species lists of one or more treaties ratified by the Kingdom, and/or its constituent countries. Large differences are apparent between the leeward and windward sectors of the Dutch Caribbean EEZ, both in terms of species composition and conservation issues. Throughout the region, cetaceans are playing an increasingly important role in island economies as an important natural attraction for eco-based recreation and tourism, and in this respect the Dutch Caribbean also possesses major potential. We here propose the establishment of a MMS as the cornerstone to sustainable conservation and management of these charismatic animals. Ecological arguments for the establishment of habitat protection by means of the concept of sanctuaries are outlined, as are the many environmental issues that would eventually need to be addressed within the sanctuary. Legal designation of a marine mammal sanctuary (MMS) would form the first and most important step which provides the framework for all broader (international cooperation) and in depth (knowledge and conservation development) initiatives. Once established, the fuller implementation of a marine mammal sanctuary should be seen as a gradual process, involving development of knowledge, policy, rules and regulations, public and stakeholder participation. In this the Netherlands would follow and importantly reinforce the efforts of other nations who have already established MMS’s within the region. Favourable pre-conditions for the establishment of a MMS in the Dutch Caribbean include the fact that a) all cetaceans are already have a legal status in the Dutch Caribbean EEZ which calls for actual protection, b) the most deleterious fishing practices are already significantly limited and controlled within Kingdom waters, c) the key enforcer, namely the Coastguard, is already strongly present (largely due to other reasons), d) the islands generally have a strong tradition of marine protected areas in coastal habitat, e) the incremental costs for research and enforcement needed to establish a sanctuary is modest, f) public support is high, thanks to the generally high level of development and awareness of the public, g) indigenous fishery practices do not conflict with cetacean conservation, and h) whale watching interests are only in their infancy. We conclude our review by proposing the following key action points to establishing a MMS: a) Legal designation of the EEZ (one or both sectors) as MMS, along with establishment of legal guidelines for interacting with cetaceans (whale watching). b) Establish bonds of cooperation with sister sanctuaries in the region (France, USA, Dominican Republic), (e.g. regional stranding and sightings data network). c) Conduct baseline quantitative surveys of cetacean distribution and assessments in light of sources of deleterious sound sources and risks of vessel strikes. d) Review and adapt existing national and insular legal frameworks to improve these, preferably by developing separate and standardized marine mammals legislation. e) Develop information systems to promote the development of a whale (cetacean) watching industry. f) Train and equip marine parks and island veterinarians to conduct elementary autopsies and collect basic stranding specimens for analysis of causes of mortality, contamination levels and genetics, and link them to international academic institutions who will accept and analyse the specimens in regional context. g) Develop species action plans (e.g. humpback). h) Conduct cetacean surveys and management reviews every 5 years to assess marine mammal status and conservation progress.
