Abstract: The Caribbean
Islands Biodiversity Hotspot is exceptionally important for global biodiversity
conservation due to high levels of species endemism and threat. A total of 755
Caribbean plant and vertebrate species are considered globally threatened,
making it one of the top Biodiversity Hotspots in terms of threat levels. In
2009, Key Biodiversity Areas (KBAs) were identified for the Caribbean Islands
through a regional-level analysis of accessible data and literature, followed
by extensive national-level stakeholder consultation. By applying the
Vulnerability criterion, a total of 284 Key Biodiversity Areas were defined and
mapped as holding 409 (54%) of the region’s threatened species. Of these, 144
(or 51%) overlapped partially or completely with protected areas. Cockpit
Country, followed by Litchfield Mountain - Matheson’s Run, Blue Mountains (all
Jamaica) and Massif de la Hotte (Haiti) were found to
support exceptionally high numbers of globally threatened taxa, with more than
40 such species at each site. Key Biodiversity Areas, building from Important
Bird Areas, provide a valuable framework against which to review the adequacy
of existing national protected-area systems and also to prioritize which
species and sites require the most urgent conservation attention.

INTRODUCTION
The Caribbean Islands
Biodiversity Hotspot is exceptionally important for global biodiversity
conservation, due to high levels of species endemism and threat. The Caribbean is home to approximately
11,000 plants species, of which 72% are endemic to the region. The vertebrates
are also characterized by extremely high levels of species endemism: 100% of
189 amphibian species, 95% of 520 reptile species, 74% of 69 mammal species and
26% of 564 species birds are unique to the Caribbean Islands. In terms of endemism
at the genus level, it ranks third among the world’s 34 Biodiversity Hotspots
with 205 plants and 65 vertebrate genera endemic to the islands (Smith et al.2004). Species restricted to the Caribbean Islands Biodiversity Hotspot
represent 2.6% of the world’s 300,000 plants species and 3.5% of the world’s
27,298 vertebrate species (Wege et al. 2010).
The high level of biological
diversity in the Caribbean is due to several factors. During the early
Cretaceous (120 to 140 million years b.p.), a
chain of volcanic islands (called Proto-Antilles) began to emerge along the
eastern edge of the Caribbean Plate in the Pacific Ocean. The plate drifted
eastward serving as a stepping-stone route for limited exchange of terrestrial
organisms between the Nearctic and Neotropicalregions. By the Eocene (58 million years b.p.), the core of the Greater Antilles achieved their present
positions (Brown & Lomolino 1998). The Lesser
Antilles are the active remnants of an ancient
volcanic chain, and are younger than the Greater Antilles. Several islands have
particularly rugged and mountainous landscapes separated by large stretches of
sea, which resulted in the isolation of populations and eventually to
speciation.
The Caribbean has suffered
from high levels of habitat loss since the arrival of Europeans in the 1490s.
This destruction has reduced the hotspot’s original estimated 229,549km2of natural vegetation to just 22,955km2 (or just 10%). The loss of
native habitat combined with other threat factors, such as introduced (alien
invasive) species, has resulted in severe and
widespread degradation of the Caribbean’s unique biodiversity. Currently, 755
plants and vertebrate species are at risk of extinction, making the region one
of the biodiversity hotspots holding the most globally threatened species.
National governments and
donor agencies have primarily invested in developing protected areas systems to
halt biodiversity loss. However, these are rarely comprehensive in their
overlap with unique species and habitats, are frequently inadequately managed,
and often fail to protect important places for biodiversity. Key Biodiversity
Areas (KBAs) in the Caribbean can be used as a tool for reviewing the efficacy
of existing national protected-area systems. KBAs provide a site-based
framework against which gaps in protected-area coverage can be identified and
candidate sites for expansion. This paper has three objectives. First, to explain the identification process for Caribbean KBAs
that was conducted within the context of developing the Caribbean Islands
Ecosystem Profile for the Critical Ecosystem Partnership Fund. Second,
to evaluate how the identified KBAs are represented in the region’s existing
protected-area systems, therefore highlighting key gaps in them, and to
prioritize among the KBAs for conservation action. Finally,
to evaluate the effectiveness of the KBA approach in guiding conservation
priorities in the Caribbean Islands Hotspot.
METHODS
The Caribbean Islands Hotspot
(Image 1) includes the biologically and culturally diverse islands of The
Bahamas (Image 2), Greater Antilles (Puerto Rico (Image 5), Jamaica (Image 3),
Cuba (Image 2) and Hispaniola [comprising the countries of the Dominican Republic
and Haiti] (Image 4)), Virgin Islands, Cayman Islands, Lesser Antilles (Image
5) and the Netherlands Antilles (Image 6). It does not include Trinidad and Tobago. So defined, the hotspot
represents a complex geopolitical region of 12 independent nations, and six
British and three U.S. overseas territories, two French overseas départements, two French overseas collectivités,
three special municipalities of the Netherlands and two constituent countries
within the Kingdom of the Netherlands. The hotspot encompasses more than four million km2 of ocean
(not included in the analysis) as well as c. 230,000km² of land area, with
the four islands of Cuba, Hispaniola, Jamaica and Puerto Rico making up about
90% of this. The coastal area included in the analysis embraces territorial
waters up to 12 nautical miles. The elevational range
spans from over 3,000m above sea level to 40m below sea level and encompasses a
diverse array of habitats and ecosystems.
The Caribbean KBAs were
identified as an integral part of developing the Caribbean Islands Hotspot
Ecosystem Profile for the Critical Ecosystem Partnership Fund during 2009 (Wege et al. 2010). For the Caribbean Islands Hotspot, only
the Vulnerability criterion was applied to select KBAs, with the confirmed presence
of globally threatened species triggering the definition of a KBA. The
Irreplaceability criterion was not applied due to lack of quantitative data for
other taxa in the hotspot. This
criterion is currently only used to define KBAs for birds, as this is the only
group for which the concept of restricted-range species has been quantitatively
defined: species with global breeding ranges of less than 50,000km2(Stattersfield et al. 1998). However, to
prevent a bias toward site priorities for birds, KBAs in the Caribbean Islands
Hotspot are identified only based on the Vulnerability criterion.
The KBA identification
process comprised a desk-based, regional-level analysis of accessible data and
literature, followed by national-level stakeholder consultations coordinated byBirdLife International, in collaboration with the
Durrell Wildlife Conservation Trust, the University of Bath and the New York
Botanical Garden, and with technical support from Conservation International.
Important Bird Areas (IBAs), documented by BirdLife partners and collaborating organizations in 2008 (BirdLife International 2008), were used as a scientifically
robust starting point for KBA identification.
This foundation of IBAs was
supplemented by applying the Vulnerability criterion to non-avian taxa to
define terrestrial KBAs based on the occurrence of globally threatened species
as categorized on the 2008 IUCN Red List (a global, standardized assessment of
species threat status). The taxonomic groups used to define KBAs were land-based
mammals, birds (through the IBA process previously mentioned), amphibians,
reptiles and plants. Sea turtle nesting beaches were included in the analysis
where more than 100 crawls annually had been recorded (Dow et al. 2007). KBAs
were delineated using a geographic information system (GIS) and by taking into
consideration the distribution of available habitat for the globally threatened
species, and also land/ protected area management units. The degree of
protection of the KBAs was analyzed against the 2010 World Database on
Protected Areas (WDPA).
National profile coordinators
in The Bahamas (Bahamas National Trust), Dominican Republic (Grupo Jaragua), Haiti (Société Audubon Haïti), Jamaica (BirdLife), Lesser Antilles (BirdLifein Barbados) and Puerto Rico (Sociedad Ornitológica Puertorriqueña)
facilitated a review of priorities within their own countries. In Cuba, it was
not possible to conduct the analysis for taxonomic groups other than birds.
National workshops were held in Dominican Republic, Haiti and Jamaica during
June 2009, with a region-wide workshop held in July 2009 on Antigua as a formal
part of the 17th Regional Meeting of the Society for the
Conservation and Study of Caribbean Birds.
RESULTS
A total of 284 Key
Biodiversity Areas were defined for all the countries and territories contained
within the Caribbean Islands Biodiversity Hotspot (Table 1). The 284 KBAs in the Caribbean Islands
Hotspot cover just over 50,000km2, or roughly 22% of the terrestrial
and coastal portion of the hotspot. Half of the KBAs are either fully or
partially protected according to the 2010 WDPA (Images 1–6).
In total, 409 globally
threatened plants and vertebrate species triggered the Vulnerability criterion
to define KBAs (hereafter referred as trigger
species). No data were available
for the other 346 globally threatened species, most of which were plants, at
the time of this analysis. Plants had the highest number of globally threatened
species, while for vertebrate species groups, amphibians and then birds were
the most abundant groups (Table 2). However, globally threatened birds were
responsible for defining the largest number of KBAs, followed by amphibians and
plants (Table 3). The
majority of KBAs were defined by the presence of multiple globally threatened
trigger species, with almost half of all KBAs (141 or 49.64%) supporting two to
10 trigger species and 28 (or 9.86%) by 11 to 44 species. Cockpit Country in
Jamaica supports an incredible 60 globally threatened species, followed by
Litchfield Mountain–Matheson’s Run, Blue Mountains (both with 44) and
Massif de la Hotte in Haiti (with 42). On the other hand, 114 (or 40%) KBAs
were identified for a single trigger species (Table 4).
A total of 173 (or 42.29%) of
the trigger species have distributions confined to just one KBA (see Table 5).
However, 25 KBAs hold populations of more than one of these “single-site”
species with Cockpit Country, Blue Mountains and Massif de la Hotte each supporting populations of more than 20 such
species. An important result of the KBA process was the identification of 56 KBAs which contained the only record of a globally
threatened species in the Caribbean Islands Biodiversity Hotspot. No fewer than
19 of these KBAs were identified in 2010 as global Alliance for Zero Extinction
(AZE) sites (Tables 4 and 5)—defined by the presence of Critically
Endangered or Endangered species confined to just a single site. One hundred and sixty nine (169 or
41.32%) of the trigger species occur only in two to five KBAs and the other 67
(16.38%) trigger species occur in more than six KBAs (Table 4).
DISCUSSION
The countries with the
greatest numbers of Key Biodiversity Areas are the large islands of the Greater
Antilles and multi-island countries such as The Bahamas. This is to be expected
as the principles of island biogeography dictate that the larger (and older)
the island, the greater the species diversity. Higher species diversity on each
of the Greater Antilles, combined with greater ecosystem, habitat and
altitudinal diversity, has led to larger numbers of endemic species and
consequently higher numbers of globally threatened taxa. Small islands in
archipelagos such as The Bahamas often result in taxonomic isolation and the
presence here of globally threatened species occupying very small ranges (often
confined to a single island) has in turn led to the definition of relatively
large numbers of KBAs. In Cuba, the KBAs included only IBAsas it was not possible to incorporate the results of analyses of other
taxonomic groups or consultations with experts for the definition of other
sites.
The amount and quality of
available data on the distribution of globally threatened species among
Caribbean KBAs vary between taxonomic groups but the sites identified will
almost certainly be important for other groups for which data are not currently
available. However, there are likely to be additional sites holding globally
threatened species that have not been identified during this process. This is
because reptiles, plants (especially cacti and orchids) and bats have not been
systematically assessed against Red List criteria. Neither have freshwater fish
(of which there are numerous endemics in the region), such that just five have
so far been categorized as globally threatened, and no KBAs were defined for
this group.
In addition to the occurrence
of globally threatened species (the Vulnerability criterion), KBAs can also be
defined on the basis of the presence of restricted-range species (the
Irreplaceability criterion): their inclusion as a next step may result in a
better coverage of the poorly represented taxonomic groups mentioned above.
Sites regularly supporting significant populations of restricted-range species
are global conservation priorities because there are few or no other sites in
the world where conservation action for these species can be taken. However,
there are no quantitative data for restricted-range species (other than birds)
in the hotspot and thus this criterion could not be applied.
The main threats to the
terrestrial biodiversity of the insular Caribbean, as prioritized during the
national ecosystem profiling workshops in order of highly significant regional
threat or impact are: invasive species; residential and
commercial development; severe weather events and global climate change;
agricultural expansion and intensification; over-exploitation of natural
resources; mining and energy production; pollution; transportation; and
geological events. There is a complex mix of interacting socio-economic, political, cultural
and environmental factors that are driving environmental change and threatening
biodiversity (and thus the KBAs) in the insular Caribbean. Principal among
these are the increasing human population and material consumption, poverty and
inequitable access to resources, the inherent economic and environmental
vulnerability of the islands to external forces, such as changes in global
trade regimes, and climate change. Some of these, such as poverty, are local or
national issues, while others, such as climate change, require attention at the
global level. All these drivers can be either exacerbated or mitigated by
public policies and institutional arrangements, at national, regional and
international levels.
A number of constraints need
to be overcome to address the environmental threats and achieve more effective
conservation of biodiversity and ecosystem services. The main ones discussed
during the national workshops and consultations in order of highly significant
regional barrier are: weak and ineffective policy; poor land-use planning;
limited capacity and resources for biodiversity conservation; inefficient
institutional frameworks; poor participation by stakeholders; limited technical
and scientific knowledge for decision-making; and lack of awareness of
biodiversity and ecosystem services (particularly their value) among
decision-makers and the general public.
Most countries have
significantly updated, or are in the process of updating (e.g. Haiti and St.Vincent), their policies and legislation on biodiversity,
environmental management and sustainable development while their obligations
under international agreements have helped drive this process (Brown et al.
2007). However, there exists significant variation among countries with regard
to comprehensiveness and effectiveness, particularly concerning the protection
of threatened biodiversity and ecosystems (BirdLifeInternational 2008), and there is a need for specific analyses of “gaps” in
legislation and policies, which very few countries have undertaken (an
exception being Jamaica [NEPA 2003]). Overall, national public policy
frameworks for environmental management remain largely oriented toward control,
regulation and a reactive approach to environmental issues, although new
approaches and instruments, including environment service markets, have begun
to be promoted by some donors, governments and NGOs as means of changing
destructive patterns of behavior.
Environmental policy in the
Caribbean tends mostly to address environmental issues and impacts rather than
their underlying root causes/drivers, such as human population increase. In the
case of climate change, Caribbean countries do not consider themselves to be
net contributors and therefore policy responses are largely limited to
adaptation. All the countries in the hotspot are active participants in the
main multilateral environmental agreements. All are signatories to the three
“Rio Conventions”—the UN Convention on Biological Diversity, UN
Convention to Combat Desertification, and the UN Framework Convention on
Climate Change —and most are members of the other key biodiversity
related agreements, such as the Ramsar Convention,
the World Heritage Convention and the Convention on International Trade in
Endangered Species, but not the Convention on Migratory Species.
At the regional level, the
main agreement is the Convention for the Protection and Development of the Marine
Environment of the Wider Caribbean Region (Cartagena Convention) and its three
Protocols. These together
constitute the only legal instrument for regional cooperation on environmental
issues for the wider Caribbean, although not all signatory countries are
properly meeting their commitments, e.g. required legislation not enacted,
management plans not developed, and biodiversity action plans not in place.
Key Biodiversity Areas can
achieve the following:
(i) Help Caribbean
nations honour their commitments to multilateral
environmental agreements
(ii) Provide the basis for
protected area gap analyses (as is the case in Haiti where KBAs are being used
in the development of the national system for protected areas plan)
(iii) Provide a prioritized
framework within which to monitor the status of biodiversity in the region.
