Marine Invasive Species
The flora and fauna
of the Wider Caribbean Region (WCR) is diverse and has significant ecological,
aesthetic, economic and amenity value to the countries and territories of the
region. Increasingly, invasive species
are seen as a threat to indigenous biodiversity, through their impacts on
natural and semi-natural habitats and ecosystems and are now widely cited as
the second greatest global threat to biodiversity, after habitat destruction.
The impacts of invasive species can be ecologically complex, operating at
ecosystem, habitat, community, species and genetic levels.
The issue of invasive species as an environmental and
sustainable development threat is increasingly recognized by a number of
treaties such as the Convention on Biological Diversity (CBD). Article 12 of
the Specially Protected Areas
and Wildlife (SPAW) Protocol outlines that each Party shall take all
appropriate measures to regulate or prohibit intentional or accidental
introduction of non-indigenous (=alien) or genetically altered species to the
wild that may cause harmful impacts to the natural flora, fauna or other
features of the WCR.
Little is known or
documented on the status of marine invasive species in the Caribbean beyond a
few instances (e.g. Perna viridis - green mussel). Indeed, a 2003 compilation
listed of 552 invasive species in the insular Caribbean, only 18 of which were
marine (Kairo et al., 2003*). The authors speculated that this was at least in
part because technological advances facilitating
the reporting of marine species (e.g. improvements in diving equipment) were
recent. In addition, there was often difficulty in determining whether newly
reported marine species were introduced aliens or merely native species that
had formerly gone unobserved. It was concluded that there was a gap in
knowledge regarding the status of introduced organisms in the marine
environment, and the threat that these may constitute.
Therefore, in keeping
with the approved workplan and budget of the regional SPAW programme.
UNEP-CAR/RCU has commissioned the Caribbean and Latin America Regional Centre
(CLARC) of CAB International (CABI) to undertake a desk study to “produce a
compilation of information on national and regional capacities and experiences
on marine invasive species management programmes in the Wider Caribbean,
including ballast water management”.
CABI-CLARC is
currently collating available information from various public domain sources.
However, many organizations / agencies in the Caribbean do not have public
domain sites and there are thus large information gaps. There are also constant
organizational changes within the public administration systems. Thus, in order
to collect the necessary updated information for the study, a simple
questionnaire (see 'related content' below) is available for your completion. It is aimed at capturing relevant information based
on (up-to-date) facts and figures, often only available within the country(s).
This questionnaire is being circulated to all focal points for a three-week
period for response. Collated information will be shared with List-serve
members for validation in order to minimize errors.
Your cooperation in
providing the requested information in a timely manner will facilitate a speedy
completion of the list so that further, follow-up activities can be planned in
accordance with the needs identified through this study. Completed
questionnaires should be sent to Mrs. Vyjayanthi Lopez at v.lopez@cabi.org
by March 22, 2006.
Sincerely,
CEP Secretariat.
