Background: PSSA framework + Resolution A.927(22) criteria
A Particularly Sensitive Sea Area is an area recognised by the International Maritime Organization as needing special protection through IMO action because of its ecological, socio-economic or scientific significance and its vulnerability to damage from international shipping. The framework began with Assembly Resolution A.720(17) of 1991, was refined through Resolution A.885(21) of 1999, and reached its modern form in Assembly Resolution A.927(22) of 29 November 2001 on the Guidelines for the Designation of Special Areas under MARPOL 73/78 and Guidelines for the Identification and Designation of Particularly Sensitive Sea Areas. The current operative instrument is Resolution A.982(24) of 1 December 2005, the Revised PSSA Guidelines, which superseded A.927(22) but preserved most of its substantive content. The Sabana-Camagüey designation in 1997 predated A.927(22) and was prepared under the earlier A.720(17) framework, then re-evaluated in subsequent Cuban submissions to the Marine Environment Protection Committee in light of the revised criteria.
The PSSA framework rests on three criterion families: ecological, socio-cultural and economic, and scientific and educational. A coastal state proposes the designation through MEPC, identifying the area, presenting the criteria evidence, and proposing Associated Protective Measures drawn from existing IMO instruments. The APMs are the operational teeth of the PSSA: routeing measures under SOLAS Chapter V Regulation 10, mandatory ship reporting under Regulation 11, mandatory pilotage in some PSSAs, and discharge restrictions where the area is also a MARPOL Special Area. Without APMs the PSSA is essentially an awareness designation; with binding APMs it is an enforceable regulatory regime.
The Sabana-Camagüey PSSA was the first PSSA designated in the Wider Caribbean Region and the third or fourth globally depending on counting convention. The Cuban submission anchored the proposal on the ecological richness of the archipelago, the cultural and economic value to Cuban coastal communities, and the scientific significance as a long-studied tropical shallow-shelf reference ecosystem. The proposed APMs were modest, reflecting the political and operational constraints of the late 1990s: routeing recommendations rather than mandatory ATBA, marine protected area zoning under Cuban domestic law, and engagement with the Cartagena Convention 1983 regional architecture rather than IMO-binding instruments.
Ecological criteria for PSSA designation
Under Resolution A.927(22) Annex 2 and the predecessor A.720(17), the ecological criteria for PSSA designation comprise eleven elements. Uniqueness or rarity addresses ecosystems or species not found elsewhere or rare globally. Critical habitat captures areas essential for the survival, reproduction or recovery of marine species. Dependency identifies ecosystems with strong inter-species dependencies, such as coral reef systems supporting fishery resources. Representativeness captures areas typifying a habitat type, biogeographic region or ecological process. Diversity addresses high species, genetic or habitat variety. Productivity identifies areas of high natural biological productivity such as upwelling zones or fringing reef systems. Spawning or breeding grounds captures sites essential for fish, mammal, bird or turtle reproduction. Naturalness addresses areas largely free from human-induced perturbation. Integrity captures functionally complete ecological units. Vulnerability identifies areas particularly susceptible to degradation by natural events or human activity. Bio-geographic importance captures distinctive biogeographic transitions or refugia.
Sabana-Camagüey satisfies the ecological criteria across the full eleven-element catalogue. Critical habitat is met by manatee, sea turtle, crocodile, flamingo and reef-fish populations. Diversity is exceptional: the Cuban archipelago hosts the highest marine species count in the Caribbean basin per unit area, with documented diversity in corals, fish, molluscs, crustaceans, seabirds and waterbirds. Productivity is high across mangrove, seagrass and reef habitats with measured carbon fixation comparable to the most productive tropical shelf systems. Naturalness in the late twentieth century was high relative to other Caribbean shelves due to limited industrial fishing, modest coastal-tourism development and the absence of major coastal industry. Vulnerability to ship-source pollution is acute given the narrow shelf channels and the proximity of international shipping lanes through the Old Bahama Channel and the Nicholas Channel.
The Cuban submission emphasised representativeness as a tropical shallow-shelf ecosystem, the bio-geographic importance as a meeting zone between Greater Antillean and continental Caribbean assemblages, and integrity as a functionally connected mangrove-seagrass-reef continuum running 465 km along the coast. The criteria assessment was peer-reviewed by Cuban biologists at the Instituto de Oceanología and the Centro de Investigaciones de Ecosistemas Costeros (CIEC) in Cayo Coco, with participation by international partners under the GEF UNDP Sabana-Camagüey Ecosystem Project.
Socio-economic + scientific criteria
The socio-economic criteria address human-use values: economic benefit, recreation, human dependency on coastal resources, and cultural heritage. The Cuban submission documented the dependency of approximately 200,000 inhabitants of the four coastal provinces on archipelago resources, the importance of the artisanal fishery for shrimp, lobster (Panulirus argus), conch (Strombus gigas) and finfish, and the developing tourism economy at Cayo Coco and Cayo Guillermo. The Jardines del Rey tourism corridor, formally launched in 1988 with the Cayo Coco causeway and expanded through the 1990s, is the principal commercial-tourism axis of the north coast and one of two major Cuban beach destinations alongside Varadero.
Cultural heritage addresses the historical importance of the archipelago in Cuban history. The keys figured in the writings of Ernest Hemingway, who fished the Cayo Guillermo and Cayo Coco region in the 1940s, with the area serving as the setting for Islands in the Stream (published posthumously in 1970). Earlier history runs to indigenous Taíno sites on Cayo Coco and Cayo Romano, sixteenth-century Spanish exploration, eighteenth and nineteenth-century smuggling and pirate use, and the first Cuban revolutionary use of the keys for arms shipments to the mainland in the 1950s.
The scientific and educational criteria address research value, baseline, monitoring and education roles. Sabana-Camagüey has been a Cuban research focus since the Felipe Poey zoological inventories of the nineteenth century. The CIEC at Cayo Coco, established in 1991, has produced a long ecological time series including coral cover monitoring, fish biomass surveys, mangrove dynamics and seagrass productivity. The Instituto de Oceanología in Havana provides oceanographic and chemical baseline data. International scientific partnerships have included the Smithsonian Tropical Research Institute, the University of Havana, the Centro de Estudios y Servicios Ambientales (CESAM) and partners in Mexico, Canada and the European Union.
The combination of ecological, socio-economic and scientific value supported a strong PSSA submission, with vulnerability to international shipping demonstrated through pre-1997 incidents in the Old Bahama Channel and projected oil and chemical traffic growth.
Associated Protective Measures (APM): ATBA, TSS, MSR, pilotage
The PSSA framework permits four principal categories of Associated Protective Measure. The area-to-be-avoided (ATBA) is the strongest measure, drawn from SOLAS Chapter V Regulation 10, prohibiting transit by specified vessel types and sizes in a defined area. ATBAs are the operational backbone of the Tubbataha PSSA, the Galapagos PSSA and parts of the Great Barrier Reef PSSA. The traffic separation scheme (TSS) channels vessel traffic into defined lanes, drawn from the same Regulation 10. Mandatory ship reporting (MSR) under Regulation 11 requires vessels to report position and cargo at designated entry and exit waypoints, providing real-time situational awareness. Mandatory pilotage is permitted in territorial waters of the coastal state and may extend to recommended pilotage in adjacent waters; the Great Barrier Reef inner-route pilotage is the canonical example.
Additional APMs include discharge restrictions where the PSSA overlaps with or is adjacent to a MARPOL Annex I Special Area, MARPOL Annex II noxious-liquid Special Area, or other annex-specific zone; anchoring restrictions, often as a no-anchoring zone covering coral reef substrate; speed limits in defined approach corridors; and vessel-type exclusions for tankers, bulk carriers, dangerous-cargo carriers or vessels above a defined gross tonnage threshold.
The Cuban submission for Sabana-Camagüey proposed a more limited APM mix. The principal measures were routeing recommendations in the Old Bahama Channel and the Nicholas Channel rather than mandatory ATBA, non-binding pilotage advisories rather than mandatory pilotage, and reliance on Cuban domestic marine protected area zoning for in-area restrictions on anchoring, fishing and dive activity. Mandatory ship reporting and a binding traffic separation scheme were not included in the original 1997 designation. The choice of advisory APMs reflected late-1990s political constraints, the absence of dense container or tanker traffic immediately threatening the archipelago, and the Cuban preference for domestic regulation over IMO-instrument enforcement on foreign-flag vessels.
The consequence has been that the Sabana-Camagüey PSSA functions principally as an awareness and regional-cooperation designation rather than as an enforceable regime against foreign-flag transit. This contrasts sharply with the post-2000 PSSAs (Galapagos, Tubbataha, Saba Bank), which adopted binding ATBAs and mandatory reporting, drawing on the operational lessons of the Sabana-Camagüey experience.
Sabana-Camagüey: 1997 MEPC.74(40) designation
Resolution MEPC.74(40) was adopted at the fortieth session of the Marine Environment Protection Committee in September 1997. The Cuban delegation, led by the Ministerio de Ciencia, Tecnología y Medio Ambiente (CITMA) with support from the Ministerio de Transporte and the Capitanía de Puerto authorities, submitted the proposal as MEPC 39/8 in 1996 with revisions for the September 1997 session. The proposal was supported by the United Nations Environment Programme, the Global Environment Facility and the United Nations Development Programme under the GEF Sabana-Camagüey Ecosystem Project, an early flagship of the GEF International Waters portfolio.
The Resolution sets out boundary coordinates, the criteria evidence under each PSSA family, and the proposed Associated Protective Measures. The boundary follows the outer barrier reef on the seaward side and the Cuban mainland coast on the landward side, running approximately 465 km from a point near Cárdenas in Matanzas Province east-northeast to a point near Nuevitas in Camagüey Province, with an extension into Las Tunas Province along the Golfo de Guacanayabo approach.
The designation was largely uncontested at MEPC 40, with regional support from CARICOM members, Mexico and the broader Wider Caribbean Region Cartagena Convention parties. The United States did not oppose the designation, although bilateral political tensions limited subsequent cooperation. The IMO Secretariat published the designation in the IMO Ships’ Routeing publication and through routine Notices to Mariners issued by the Capitanía Nacional de Puerto with notification to UKHO, US NGA, the Canadian Hydrographic Service and commercial chart publishers.
Geography: 75,000 km² spanning Villa Clara, Ciego de Ávila, Camagüey, Las Tunas
The Sabana-Camagüey Archipelago is the largest of the four major Cuban coastal archipelagos, alongside Los Colorados off the north-western coast, Jardines de la Reina off the southern Camagüey-Ciego de Ávila coast, and Los Canarreos off the south-western coast. Sabana-Camagüey runs along the north-central Cuban coast spanning the four provinces of Villa Clara in the west, Ciego de Ávila in the central section, Camagüey in the central-eastern section, and Las Tunas at the eastern terminus.
The PSSA boundary encloses approximately 75,000 square kilometres of shallow shelf, with depths typically less than 25 metres on the inner shelf, deepening to 30 to 60 metres at the outer barrier reef edge before dropping into the deep Atlantic and Old Bahama Channel beyond. The Old Bahama Channel separates Sabana-Camagüey from the Bahama Bank to the north and is the principal international shipping channel along the Cuban north coast, used by tanker, bulk and container traffic between the Gulf of Mexico, the Atlantic and the Caribbean. The Nicholas Channel runs west of the archipelago between Sabana-Camagüey and the Salt Cay Bank, providing a secondary shipping access.
The archipelago is divided into the Sabana subgroup in the western section (Villa Clara coast, including Cayo Santa María, Cayo Las Brujas, Cayo Ensenachos and Cayo Francés) and the Camagüey subgroup in the eastern section (Ciego de Ávila and Camagüey coasts, including Cayo Coco, Cayo Guillermo, Cayo Romano, Cayo Sabinal and Cayo Cruz). The two subgroups are connected by an almost continuous chain of shoals and small keys, hence the combined name. The Bahía de Buenavista in the western section and the Bahía de Nuevitas in the eastern section are the two principal interior bays, both with significant ecological value and both partially overlaid by RAMSAR or biosphere-reserve designations.
The four-province division has administrative consequences. Each province operates a Provincial Office of CITMA, a Provincial Capitanía de Puerto, a Provincial branch of the Centro Nacional de Áreas Protegidas (CNAP) and provincial fisheries and tourism authorities, with the four-province coordination handled by the central CITMA office in Havana through the Sistema Nacional de Áreas Protegidas (SNAP) framework.
~2,517 keys (cayos): Coco, Guillermo, Romano, Sabinal
The archipelago contains approximately 2,517 keys (cayos) of varying size, from emergent sand cays of less than 1 hectare to the principal islands of several thousand hectares. The exact count varies between Cuban surveys depending on definition (mangrove islet, sand cay, vegetated key, ephemeral shoal), with most authoritative sources converging on the 2,500-key figure.
Cayo Coco is the largest single key in the archipelago at approximately 370 square kilometres, located in the Ciego de Ávila section. It hosts the Centro de Investigaciones de Ecosistemas Costeros (CIEC) scientific station, the principal Jardines del Rey tourism developments at the Pedraplén causeway terminus, and several major hotel resorts. Coco is connected to the mainland by the Pedraplén causeway constructed 1988-1992, a 27 km elevated road across the Bahía de Perros that opened the northern keys to mass tourism. The causeway includes 47 culvert bridges to permit tidal exchange, although hydrological studies through the GEF Sabana-Camagüey Project documented partial flow restriction with consequent salinity and sediment effects on the inner bay.
Cayo Guillermo is the second principal tourism key, immediately west of Cayo Coco, at approximately 13 square kilometres. It is the famous Hemingway location and hosts a smaller cluster of high-end resorts.
Cayo Romano is the largest key in the Camagüey provincial section at approximately 770 square kilometres, the most extensive single landmass in the archipelago. It is largely undeveloped, with significant flamingo, manatee and crocodile habitat, low-density cattle and goat grazing in the interior, and a small artisanal fishing settlement at Punta Caimán. Romano is connected to the mainland by a more recent causeway with limited tourism development to date.
Cayo Sabinal is east of Cayo Romano in Camagüey Province at approximately 335 square kilometres, with extensive beach and mangrove habitat, the Faro Colón lighthouse dating from 1850, low-density cattle ranching and protected status under the SNAP system. Sabinal connects to the mainland near Nuevitas through a short causeway and access to the Bahía de Nuevitas.
Smaller but ecologically significant keys include Cayo Cruz in Camagüey, Cayo Paredón Grande with its Cuban-origin lighthouse, Cayo Anclitas and Cayo Caguanes in the Sabana subgroup, and the small bird-colony cays of Cayo Mégano de Casiguas and Cayo Felipe de Barlovento.
Coral reef + mangrove + seagrass habitats
The ecological architecture of Sabana-Camagüey rests on a coupled mangrove-seagrass-reef continuum running parallel to the Cuban coast for 465 km. The outer barrier reef is one of the most extensive fringing-barrier reef systems in the Caribbean, running from approximately Cayo Cruz del Padre in the west to Cayo Sabinal in the east, with documented coral cover historically reaching 40 to 50 percent on the optimum sectors. The reef hosts approximately 50 stony coral species and 30 octocoral species, with characteristic Caribbean assemblages of Acropora palmata (formerly dominant elkhorn), Acropora cervicornis (staghorn), the brain corals Diploria and Pseudodiploria, the boulder corals Orbicella (formerly Montastraea) annularis and faveolata, and the fire coral Millepora.
The reef ecosystem supports approximately 400 fish species, with high abundance of grouper (Mycteroperca, Epinephelus), snapper (Lutjanus), parrotfish (Scarus, Sparisoma), surgeonfish (Acanthurus) and reef sharks. The Sabana-Camagüey reef is a major spawning ground for the Cuban regional fishery, with historically documented spawning aggregations of Nassau grouper (Epinephelus striatus), mutton snapper (Lutjanus analis) and cubera snapper (Lutjanus cyanopterus) at specific reef passes.
Mangrove forests cover approximately 4,000 square kilometres along the inner shelf, dominated by red mangrove (Rhizophora mangle), black mangrove (Avicennia germinans), white mangrove (Laguncularia racemosa) and buttonwood (Conocarpus erectus). Sabana-Camagüey contains roughly 25 percent of all Cuban mangrove cover, the largest single concentration in Cuba and one of the largest in the Caribbean. The mangroves provide nursery habitat for reef and pelagic fish, feeding habitat for manatees, nesting and roosting habitat for waterbirds including the flamingo concentrations, and shoreline stabilisation against tropical-cyclone storm surge.
Seagrass beds cover approximately 18,000 square kilometres of the inner and middle shelf, dominated by turtlegrass (Thalassia testudinum), manatee grass (Syringodium filiforme) and shoalgrass (Halodule wrightii). The seagrass supports queen conch (Strombus gigas), spiny lobster (Panulirus argus), sea turtles (especially green turtles grazing on Thalassia), manatees and a large fishery resource of fish and crustaceans. Sabana-Camagüey contains approximately 20 percent of all Cuban seagrass area and one of the most extensive intact seagrass meadow complexes in the wider Caribbean.
The connectivity between the three habitat types is functional and biological. Larvae spawned on the reef recruit to mangrove and seagrass nursery habitats, juveniles grow through ontogenetic habitat shifts, and adults return to the reef. Productivity transfers through the food web include detrital export from mangroves, seagrass production supporting herbivore biomass, and reef fish biomass supporting human fisheries and the broader ecosystem.
Manatee, crocodile, sea turtle, West Indian flamingo
The vertebrate fauna of Sabana-Camagüey includes a suite of charismatic and globally significant species supporting the PSSA designation.
The West Indian manatee (Trichechus manatus manatus) is present in resident populations across the inner-bay and mangrove channel habitats of Sabana-Camagüey, with estimated Cuban totals in the low hundreds and Sabana-Camagüey holding the largest single Cuban subpopulation. The species is listed as Vulnerable by the IUCN Red List and is protected under Cuban law. Threats include vessel-strike, fisheries entanglement, mangrove habitat loss and pollution, with vessel-strike particularly relevant to the PSSA. The Bahía de Buenavista, the Bahía de Nuevitas and the inner channels of Cayo Romano are the principal manatee habitats.
The American crocodile (Crocodylus acutus) occurs in the mangrove channels and estuarine reaches of Sabana-Camagüey, with the Cuban crocodile (Crocodylus rhombifer), endemic to Cuba, occurring at the south-western range margin in the Zapata Swamp further west and not principally in Sabana-Camagüey but with documented straying into the western archipelago. The American crocodile is Vulnerable on the IUCN Red List; the Cuban crocodile is Critically Endangered, with most of the global wild population in the Zapata Swamp adjacent to the Sabana-Camagüey western section.
Sea turtles include four nesting and foraging species: green turtle (Chelonia mydas), hawksbill (Eretmochelys imbricata), loggerhead (Caretta caretta) and the rarer leatherback (Dermochelys coriacea) on offshore foraging only. The keys host significant nesting beaches, with documented hawksbill rookeries on Cayo Sabinal, Cayo Romano and Cayo Coco, and green turtle rookeries on the eastern keys. The Cuban Sea Turtle Conservation Programme has monitored Sabana-Camagüey nesting since the 1990s with nest protection, hatch monitoring and threat-reduction measures.
The West Indian flamingo (Phoenicopterus ruber, sometimes Phoenicopterus ruber ruber) is the flagship species for the archipelago, with documented concentrations exceeding 10,000 individuals at peak season in the salinas and shallow lagoons of Cayo Romano, Cayo Coco and the Bahía de Buenavista.
The Sabana-Camagüey flamingo population is one of the largest concentrations in the Caribbean and a major regional breeding site, with the principal breeding colony on Cayo Romano. Threats include disturbance from tourism boats, illegal egg collection and habitat alteration. Avian fauna more broadly includes more than 200 documented species, with significant populations of roseate spoonbill (Platalea ajaja), reddish egret (Egretta rufescens), white ibis (Eudocimus albus), the endemic Cuban gnatcatcher (Polioptila lembeyei) on the keys, and migratory shorebirds and waterfowl.
Cuba’s proposed APMs: routeing recommendations + MPA zoning
The Cuban submission proposed three principal Associated Protective Measure categories. The first was routeing recommendations in the Old Bahama Channel and the Nicholas Channel, advising vessels to maintain corridor centrelines of approximately 25 to 35 km offshore from the outer barrier reef, with corresponding minimum-clearance lines for tankers and large bulk carriers. The recommendations were published through the Capitanía Nacional notices to mariners, the IMO Ships’ Routeing publication and through subsequent revisions of UKHO and US NGA charts. The recommendations were not adopted as a formal IMO traffic separation scheme under Regulation 10.
The second APM was marine protected area zoning under Cuban domestic law, leveraging the existing protected-area framework managed by CNAP. The zoning included no-take fishery zones on the most ecologically sensitive reef sectors, no-anchoring zones over coral substrate and seagrass beds within designated protected areas, restricted-tourism zones around flamingo breeding colonies, and habitat-specific protections for manatee, crocodile and turtle areas. The MPA zoning was binding on Cuban-flag vessels and on foreign vessels in Cuban territorial waters but limited in reach against transit vessels in the Old Bahama Channel international waters.
The third APM was non-binding pilotage advice for tankers and large bulk carriers transiting the Old Bahama Channel, recommending the use of Cuban or commercial pilots familiar with the corridor and the proximate hazards. Mandatory pilotage was not adopted, and uptake remained limited.
The APM mix lacked the binding ATBA and mandatory reporting that became the operational backbone of subsequent PSSAs. The Cuban submission noted at the time that the absence of dense container or large-tanker traffic immediately adjacent to the archipelago, the relatively wide Old Bahama Channel providing offshore separation, and the political constraints on multilateral instrument implementation supported the more limited APM choice. Subsequent traffic growth, post-2000 PSSA experience elsewhere and the Cuban tourism build-up have prompted periodic re-examination, although no formal upgrade has been submitted to MEPC as of 2026.
Lack of mandatory ATBA: practical impact assessment
The absence of a mandatory area-to-be-avoided has been the principal point of operational critique of the Sabana-Camagüey PSSA. Three consequences are documented in the Cuban and international academic literature.
First, routeing compliance is high but voluntary. Old Bahama Channel transit traffic monitoring through AIS analysis and Cuban Capitanía records shows broad adherence to the recommended corridor, principally because the corridor accommodates the natural great-circle routes between Gulf of Mexico, Atlantic and Caribbean ports rather than imposing a diversion. However, occasional small-vessel intrusions, vessels in distress or weather-stop, and a small minority of cost-pressured operators have been documented inside the recommended buffer. With no mandatory ATBA there is no SOLAS-anchored basis for sanction against the foreign-flag intruder, and Cuban enforcement is limited to sovereign jurisdiction in territorial seas.
Second, post-incident response capacity is constrained. The Sabana-Camagüey PSSA has had several incident histories of ship-source pollution and grounding, principally involving smaller vessels, but the absence of a binding mandatory reporting requirement under Regulation 11 limits real-time situational awareness for Cuban authorities. The 1990s-era pre-PSSA spill record from Old Bahama Channel transits and earlier incidents underlines the historical risk profile.
Third, enforcement reach is single-jurisdictional. Cuban authorities can enforce the MPA zoning and pilotage regime within Cuban territorial waters and EEZ, but the foreign-flag transit vessel in the Old Bahama Channel is governed by flag state rules and IMO instruments. The US embargo restrictions and the absence of normalised cooperation channels with the principal flag states in the corridor (Bahamas, Liberia, Marshall Islands, Panama, Singapore, Hong Kong) limit case-by-case enforcement against foreign-flag intrusions.
The Cuban CITMA periodic environmental reports and academic assessments converge on the conclusion that the Sabana-Camagüey PSSA has been a partial success as awareness designation and regional cooperation anchor, but a limited success as enforceable maritime regulatory regime. The post-2000 PSSAs (Galapagos, Tubbataha, Saba Bank) drew explicit lessons from the Cuban experience by adopting binding ATBA and mandatory reporting from the outset.
UNESCO Man and the Biosphere Reserve (since 2000) overlay
The UNESCO Man and the Biosphere Programme designated the Buenavista Biosphere Reserve in November 2000, covering approximately 313,500 hectares in the western and central section of Sabana-Camagüey across Villa Clara and Sancti Spíritus provinces. The Biosphere Reserve overlay provides a sustainable-development framework with the standard MaB three-zone architecture: core zones for strict protection, buffer zones for low-impact use, and transition zones for sustainable development.
Buenavista core zones include the Las Picuas-Cayo Cristo and the Lanzanillo-Pajonal-Fragoso Refugios de Fauna. A second related MaB Biosphere Reserve, Caguanes in Sancti Spíritus, was designated in 2002 covering approximately 20,400 hectares. The MaB and PSSA are structurally separate but operationally complementary: MaB provides the sustainable-development and research framework on land and shallow shelf; the PSSA provides the maritime regulatory framework; CNAP and the Cuban environmental ministries coordinate across both. The relationship to the UNESCO MaB programme anchors Sabana-Camagüey in the global network of approximately 700 Biosphere Reserves.
RAMSAR Buenavista site overlay
The Convention on Wetlands of International Importance (Ramsar Convention 1971) is the principal international instrument for wetland conservation. Cuba acceded to the RAMSAR Convention in 2001 and has progressively designated six Wetlands of International Importance along its coast.
The Buenavista RAMSAR site was designated in November 2002, covering approximately 313,500 hectares in the western Sabana-Camagüey section, identical in extent to the Buenavista Biosphere Reserve. The site qualifies under multiple Ramsar criteria including Criterion 1 (representative wetland type), Criterion 2 (vulnerable, endangered or critically endangered species), Criterion 3 (biological diversity), Criterion 4 (life-cycle stage support), Criterion 5 (more than 20,000 waterbirds at peak), and Criterion 6 (more than 1 percent of a waterbird species population, satisfied by the West Indian flamingo concentration). Other Cuban Ramsar sites include the Ciénaga de Zapata, the Refugio de Fauna Río Máximo (in Camagüey adjacent to the eastern PSSA section), the Humedal Delta del Cauto, the Gran Humedal del Norte de Ciego de Ávila and the Ciénaga de Lanier.
The Río Máximo Ramsar site, designated in 2002 at approximately 22,580 hectares, lies along the Camagüey north coast within the broader PSSA sphere and contains another significant flamingo concentration. The combined Buenavista and Río Máximo Ramsar sites cover the most ecologically important wetland sectors of Sabana-Camagüey.
The Ramsar overlay provides international legal recognition, periodic ecological reporting through Ramsar Information Sheets, eligibility for the Ramsar Small Grants Fund and Wetlands for the Future funding, and reputational signalling for tourism and conservation finance. As with the MaB, the Ramsar regime is structurally separate from the IMO PSSA but operationally complementary.
Centro Nacional de Áreas Protegidas (CNAP) management
The Centro Nacional de Áreas Protegidas (CNAP) is the Cuban national protected-area authority, established in 1995 within CITMA. CNAP administers the Sistema Nacional de Áreas Protegidas (SNAP) which as of 2026 comprises more than 250 designated protected areas covering approximately 20 percent of the Cuban land area and 25 percent of the Cuban marine and shelf territory, one of the highest national protected-area coverage figures in the Latin American and Caribbean region.
Within Sabana-Camagüey, CNAP administers a network of approximately 30 protected areas at varying IUCN management category levels. Category Ia (strict nature reserve) and Category II (national park) areas include the Caguanes National Park, the Cayos de Ana María ecological reserve and several Refugio de Fauna sites for flamingo, manatee and turtle protection. Category IV (habitat/species management area) and Category VI (managed resource protected area) cover the productive fishery zones and broader mangrove-seagrass-reef matrix.
CNAP administration includes ranger deployments at the principal sites, scientific monitoring through CIEC and Instituto de Oceanología, bilateral and multilateral cooperation with international partners, and the integration of the IMO PSSA designation with the SNAP framework. The four Provincial CNAP offices coordinate through the central Havana office.
CNAP funding is principally through the Cuban national budget supplemented by international cooperation funds (UNDP, GEF, UNEP), bilateral support (notably Spain, Italy, Germany, Mexico, Canada), tourism fees from Jardines del Rey concessions, and donor philanthropy. The funding has historically been constrained relative to the protected-area scope, with consequences for ranger density, vessel availability for marine patrols, and scientific monitoring continuity.
The CNAP role in PSSA operations is substantial but indirect. CNAP enforces the MPA zoning element of the PSSA APMs, conducts the ecological monitoring that supports periodic IMO reporting, and provides the institutional anchor for the Buenavista MaB and Ramsar designations. CNAP does not directly enforce the maritime traffic-routeing element, which is the responsibility of the Capitanía Nacional de Puerto and the Cuban Border Guard.
IMO MEPC PSSA submission process (Resolution A.927(22))
The IMO MEPC PSSA submission process under Resolution A.927(22) Annex 2 and the operational guidance of MEPC/Circ.510 (1996) follows a defined sequence refined through approximately twenty PSSA proposals between 1990 and 2026, with the Sabana-Camagüey 1997 designation being one of the early test cases.
The first stage is internal preparation by the proposing coastal state, including ecological inventory under the eleven A.927(22) ecological criteria, socio-economic and scientific criteria documentation, vulnerability-to-shipping analysis, and identification of proposed Associated Protective Measures. The second stage is submission to MEPC as a formal document with a one-year lead before the target session. The third stage is MEPC plenary discussion requiring consensus from member states. The fourth stage is adoption of the MEPC Resolution designating the area as a PSSA with boundary coordinates and APM specifications. The fifth stage, where the APMs include routeing measures or mandatory reporting, is referral to NCSR (formerly NAV) and to the Maritime Safety Committee (MSC) for adoption of the SOLAS-anchored measures. The sixth stage is implementation: chart updates, notice to mariners, integration into the IMO Ships’ Routeing publication and operational deployment.
The Sabana-Camagüey process compressed several of these stages because the proposed APMs were principally non-IMO measures (Cuban domestic MPA zoning, advisory routeing, advisory pilotage). The MEPC.74(40) Resolution adopted the PSSA designation directly without parallel NAV referral for binding routeing, with consequent operational simplicity but reduced enforcement strength.
Post-1997 management challenges: enforcement + embargo
The Cuban PSSA management since 1997 has faced four sustained challenges. The first is funding constraint. The Cuban national budget through the Special Period of the 1990s and the recovery decades has been insufficient to staff and equip Sabana-Camagüey at the level of comparable PSSAs in higher-income coastal states. CNAP and Capitanía resources have been spread across the entire Cuban coast and protected-area system rather than concentrated on a single PSSA.
The second is the United States embargo. The Cuban Democracy Act of 1992, the Helms-Burton Act of 1996 and successor extensions of the United States embargo have constrained bilateral cooperation, restricted Cuban access to US-origin technology and equipment, and limited the participation of US scientific institutions, NGOs and conservation funders. The embargo restrictions have also limited Cuban participation in some hemispheric maritime regulatory cooperation frameworks where the United States plays a coordinating role. Notable exceptions include scientific cooperation under specific licences from the US Treasury Office of Foreign Assets Control, with periodic shifts in licensing scope between US administrations.
The third is vessel and aerial patrol capacity. Cuban Border Guard and Capitanía vessels available for Sabana-Camagüey patrol are limited in number and ageing, with consequent gaps in patrol coverage and response time to reported intrusions or pollution incidents. Aerial surveillance is limited and not comparable to the sustained satellite-AIS and aircraft coverage available for Tubbataha or the Great Barrier Reef.
The fourth is tourism pressure. The Jardines del Rey tourism corridor at Cayo Coco and Cayo Guillermo developed substantially after 1997, with consequent pressure on coral reef, beach, mangrove and seabird habitats. While tourism provides revenue and political support for conservation, the carrying-capacity pressures on the keys remain a sustained management challenge.
Despite these challenges the Cuban PSSA management record contains documented successes: the establishment of CIEC at Cayo Coco, the implementation of MPA zoning and ranger deployment, the integration with MaB and Ramsar overlays, and the maintenance of substantial ecological values across most of the archipelago through almost three decades of changing economic and political conditions.
Plan de Acción Nacional 2017-2030 expansion
The Plan de Acción Nacional sobre Diversidad Biológica de la República de Cuba 2016-2020 and its successor Plan de Acción Nacional 2021-2030 under CITMA articulate the Cuban national biodiversity strategy and include explicit goals for marine protected area expansion, integration with the IMO PSSA framework, and climate-adaptation measures.
The 2017-2030 plan envisages expansion of the Cuban marine and coastal protected area network from approximately 25 percent to approximately 30 percent of the marine territory, with priority targeting of unprotected or under-protected sectors of Sabana-Camagüey, Jardines de la Reina, the Los Colorados archipelago and the Los Canarreos archipelago. Specific Sabana-Camagüey expansion priorities include extension of the Buenavista MaB and Ramsar zones, additional CNAP designations on the Cayo Romano-Cayo Sabinal axis, and dedicated turtle-nesting and flamingo-breeding refuges.
The plan also commits to engagement with IMO MEPC on possible upgrade of the Sabana-Camagüey PSSA APMs, including evaluation of mandatory reporting under SOLAS Regulation 11 and possible ATBA designation in the most ecologically sensitive sectors, although no formal MEPC submission has been tabled as of 2026.
Climate-adaptation measures include sea-temperature monitoring across the archipelago, coral-bleaching response protocols, mangrove restoration in storm-damaged sectors, and strengthening of CIEC scientific capacity. The 2017-2018, 2023 and 2024-2025 mass bleaching events affected Sabana-Camagüey reefs, with documented coral cover declines and consequent recovery management challenges.
Relationship to Cartagena Convention 1983 + SPAW Protocol 1990
The Cartagena Convention 1983 for the Protection and Development of the Marine Environment of the Wider Caribbean Region, adopted at Cartagena de Indias on 24 March 1983 and entered into force on 11 October 1986, is the principal regional environmental framework convention for the Wider Caribbean Region. Cuba is a contracting party to the Cartagena Convention. The Convention secretariat is the UNEP Regional Coordinating Unit for the Caribbean (CAR/RCU) in Kingston, Jamaica.
The Cartagena Convention has three operative Protocols: the Oil Spills Protocol of 1983 covering cooperation in oil pollution emergencies; the Specially Protected Areas and Wildlife Protocol (SPAW) of 1990 covering protected area designation and species conservation; and the Land-Based Sources of Marine Pollution Protocol (LBS) of 1999 covering land-based pollution control. The SPAW Protocol 1990 adopted at Kingston on 18 January 1990 entered into force on 18 June 2000 and provides the regional framework for marine protected area designation.
Sabana-Camagüey is recognised under the SPAW Protocol as a SPAW-listed Protected Area through the protocol’s Annex listing process, providing regional-cooperation status, eligibility for SPAW Regional Activity Centre support based at Guadeloupe (CAR-SPAW-RAC), and integration with Cuban CNAP and IMO PSSA frameworks. Other Cuban SPAW-listed sites include Jardines de la Reina, the Ciénaga de Zapata, the Guanahacabibes Biosphere Reserve and several smaller sites.
The relationship between the IMO PSSA and the Cartagena Convention SPAW is structurally distinct but operationally complementary. The IMO PSSA addresses ship-source threats and operates through the IMO regulatory framework; the SPAW Protocol addresses broader area protection and operates through UNEP CAR/RCU coordination. Both regimes recognise Sabana-Camagüey as a regional priority site and contribute to the broader Wider Caribbean Region protected-area network.
Comparison to MARPOL Annex I Special Areas
A frequent point of confusion is the relationship between the PSSA framework and the MARPOL Annex I Special Area framework. The two are structurally and operationally distinct, although they share the underlying purpose of addressing ship-source pollution risk in ecologically valuable areas.
A MARPOL Special Area under MARPOL Annex I and parallel provisions in Annexes II, IV, V and VI is a defined sea area where ship-source discharges of oil, noxious liquid substances, sewage, garbage or air emissions are restricted more stringently than the general convention rules. The Annex I Special Areas as of 2026 include the Mediterranean Sea, the Baltic Sea, the Black Sea, the Red Sea, the Gulfs Area, the Gulf of Aden, the Antarctic Area, the North-West European Waters, the Oman Area of the Arabian Sea and the Southern South African Waters. The principal restrictions under Regulation 15 oil discharge criteria inside Special Areas are tighter than the general convention rules: oil-content limits typically require zero discharge or very low ppm concentrations rather than the general 15 ppm.
A PSSA under the IMO PSSA framework is a designation through MEPC Resolution that recognises ecological, socio-economic and scientific value and identifies Associated Protective Measures from existing IMO instruments. The PSSA itself does not impose discharge restrictions; the discharge restrictions, if any, are implemented through the parallel MARPOL Special Area designation or through separate IMO instruments.
The Wider Caribbean Region was designated as a Special Area under MARPOL Annex V (garbage) in 1991 and entered into operation in 1993, but is not a Special Area under Annex I (oil) as of 2026. Sabana-Camagüey therefore inherits the Annex V garbage Special Area status but does not benefit from Annex I oil discharge restrictions beyond the general convention rules. Several proposals for designation of the Caribbean as an Annex I or VI Special Area have been discussed at MEPC but have not been adopted.
The practical consequence is that the Sabana-Camagüey PSSA does not by itself impose the most stringent oil discharge restrictions. Vessels in the Old Bahama Channel and the Nicholas Channel transit under the general MARPOL Annex I 15 ppm oil discharge limit and the broader MARPOL Convention regime, supplemented by the Annex V garbage Special Area restrictions. The PSSA designation supplies the ecological-criteria recognition and the Associated Protective Measure architecture (routeing, MPA zoning, advisory pilotage), but the discharge regime is governed separately.
Place in the global PSSA list (18 designations as of 2026)
The Sabana-Camagüey PSSA is one of approximately 18 IMO-designated PSSAs as of 2026. The list, in approximate chronological order, includes the Great Barrier Reef (Australia, 1990, extended 2005); the Sabana-Camagüey Archipelago (Cuba, 1997); Malpelo Island (Colombia, 2002); Florida Keys (United States, 2002); the Wadden Sea (Denmark-Germany-Netherlands, 2002); Paracas National Reserve (Peru, 2003); Western European Waters (2004); the Canary Islands (Spain, 2005); the Galapagos Archipelago (Ecuador, 2005); the Baltic Sea (2005); Papahānaumokuākea (United States, 2007); the Strait of Bonifacio (France-Italy, 2011); the Saba Bank (Netherlands, 2012); the Torres Strait GBR extension (2005); the Jomard Entrance (Papua New Guinea, 2016); and the Tubbataha Reefs Natural Park (Philippines, 2017).
Sabana-Camagüey holds three significant historical positions: it is the first PSSA designated in the Wider Caribbean Region, predating Florida Keys (2002) and Saba Bank (2012); it was an early-period PSSA designated under the pre-A.927(22) framework, providing operational lessons that shaped the revised guidelines; and it is the largest single-state PSSA in the Wider Caribbean at 75,000 square kilometres, ahead of Florida Keys (approximately 9,500 square kilometres) and Saba Bank (approximately 2,680 square kilometres). For the global picture of the PSSA framework including all designated areas and the historical evolution from A.720(17) through A.982(24), the PSSA overview provides the parent reference. The peer Tubbataha Reefs PSSA (2017) and Saba Bank PSSA (2012) supply direct points of comparison for tropical-reef and shallow-shelf single-state designations.
Formula, assumptions, and limits
Formula
The Sabana-Camagüey PSSA boundary geometry is constructed as a coastal-shelf envelope along the Cuban north-central coast, bounded landward by the mainland coastline and seaward by the outer barrier reef edge, with provincial-administrative segmentation. The principal area metrics are:
The biological inventory metrics include:
The overlay-area metrics include:
Derivation
The 75,000 square kilometre PSSA boundary derivation reflects the Cuban submission to MEPC 39/8 (1996, revised 1997). The seaward boundary is the outer barrier reef line at typical depths of 30 to 60 metres. The landward boundary is the Cuban mainland coastline. The longitudinal boundary runs from approximately 81 degrees west near Cárdenas in Matanzas Province to approximately 76 degrees west near the Punta de Maternillos area in Camagüey Province, with the Las Tunas extension running further east. The four-province administrative coverage (Villa Clara, Ciego de Ávila, Camagüey, Las Tunas) provides the operational segmentation for CNAP, Capitanía and provincial CITMA management.
The 2,517 keys figure is a mid-1990s Cuban hydrographic and ecological survey count, which has been refined modestly in subsequent surveys. The mangrove and seagrass area derivations are CIEC and Instituto de Oceanología measurements through ground-truthed remote sensing. The flamingo population estimate is from CIEC and partner surveys at the Cayo Romano breeding colony and the Bahía de Buenavista feeding grounds during peak season, with annual variability driven by salinity, food availability and weather conditions.
Assumptions
The architecture rests on five assumptions. First, the recommended routeing in the Old Bahama Channel and the Nicholas Channel accommodates the natural great-circle shipping flows without imposing material diversion cost, supporting voluntary compliance. Second, Cuban domestic MPA zoning under CNAP provides effective in-area enforcement against Cuban-flag and territorial-water vessels, even without binding APMs against foreign-flag transit. Third, the Capitanía Nacional and Border Guard surveillance capacity, although constrained, provides adequate detection for the most consequential intrusions. Fourth, the integration with MaB, Ramsar and SPAW frameworks compounds protection beyond the IMO PSSA element. Fifth, the absence of a binding ATBA reflects historical political and operational constraints rather than ecological judgment, and remains open to upgrade through future MEPC submission.
Worked example
A Suezmax tanker of 160,000 dwt loaded at the Bahamas SOLOMON terminal bound for Galveston follows a great-circle through the Old Bahama Channel approximately 30 km north of the Sabana-Camagüey outer barrier reef. The recommended routeing imposes no measurable diversion; the operational cost is the broader awareness of the protected area, additional voyage planning attention, and adherence to general MARPOL Convention discharge restrictions plus the Annex V garbage Special Area discharge restrictions for the Wider Caribbean Region.
A 35,000 dwt product tanker on the Houston-Cienfuegos route passes through the Yucatán Channel and approaches Cienfuegos through the southern Cuban coast, not directly through Sabana-Camagüey. The PSSA imposes no operational cost beyond awareness and broader regional environmental compliance.
A 5,000 dwt general cargo vessel on a coastal Cuban-flag run between Havana and Nuevitas transits the Nicholas Channel and the Old Bahama Channel inside the recommended corridor, subject to the Cuban domestic MPA zoning, the Capitanía routeing advice, and the broader Cuban environmental and maritime regulations. Pilotage is recommended at the Nuevitas approach.
Edge cases and limits
Edge cases include: distress or genuine emergency, where SOLAS V/10 permits any vessel to deviate from any routeing measure with appropriate reporting; vessels in territorial waters, where Cuban sovereign jurisdiction applies and the MPA zoning, fisheries and tourism regulations bind directly; foreign sovereign-immune vessels including foreign navy vessels, where direct enforcement is constrained but bilateral arrangements may apply; tourism and dive expedition vessels licensed at Jardines del Rey, where TCC specific operational restrictions apply; artisanal Cuban fishing vessels, subject to Cuban fisheries regulations and CNAP MPA zoning; and the persistent challenge of the United States embargo restrictions on bilateral cooperation, which limit the integration of US-flag vessels into joint surveillance or response arrangements.
The principal operational limit is the absence of binding ATBA and mandatory reporting, which constrains the regulatory reach against foreign-flag transit through the Old Bahama Channel. The principal scientific limit is the temporal continuity of CIEC monitoring through the changing Cuban economic context. The principal political limit is the embargo and the consequent constraint on multilateral engagement.
Regulatory basis
The regulatory basis is sixfold. The IMO PSSA designation is Resolution MEPC.74(40) of September 1997. The PSSA framework is Resolution A.720(17) of 1991, refined through A.885(21) of 1999, A.927(22) of 29 November 2001, and A.982(24) of 1 December 2005. Routeing recommendations are referenced under SOLAS Chapter V Regulation 10. Discharge restrictions are anchored in MARPOL Annex I, in particular Regulation 15 oil discharge criteria, and the broader MARPOL Convention. The Cuban domestic basis is the Ley 81 del Medio Ambiente of 1997, the Ley 33 de Protección del Medio Ambiente of 1981, the Decreto-Ley 201 del Sistema Nacional de Áreas Protegidas of 1999, the Decreto-Ley 212 de Gestión de la Zona Costera of 2000, and the implementing regulations administered by CITMA, CNAP, the Ministerio de Transporte and the Capitanía Nacional. The international legal context is UNCLOS Articles 211 and 192, the Convention on Biological Diversity of 1992 (Cuba is a party), the RAMSAR Convention (Cuban accession 2001), the UNESCO MaB programme, the Cartagena Convention 1983 and the SPAW Protocol 1990.
Common errors
Five errors recur in commercial and academic discussion of Sabana-Camagüey. First, conflating the PSSA designation with a mandatory ATBA, when in fact the APMs are advisory routeing and MPA zoning rather than binding ATBA. Second, assuming the Wider Caribbean Region is a MARPOL Annex I Special Area, when it is currently only a MARPOL Annex V garbage Special Area. Third, conflating the Buenavista MaB Biosphere Reserve, the Buenavista Ramsar site and the broader Sabana-Camagüey PSSA, which have overlapping but not identical boundaries (the MaB and Ramsar at approximately 313,500 hectares cover the western section, while the PSSA at 75,000 square kilometres covers the entire archipelago). Fourth, underestimating the role of CNAP and the Cuban SNAP framework as the principal in-area management authority, distinct from the maritime authorities. Fifth, treating the Sabana-Camagüey PSSA as comparable in enforcement profile to Galapagos or Tubbataha, when in fact the operational profile reflects the more limited APM mix and the broader Cuban political and economic context.
