SECTION 1: INTRODUCTION
1.1 INTRODUCTION
The parish of Portland is located at the north‐eastern section of Jamaica. The majority of the upper and middle watershed areas of the parish are within the Blue and John Crow Mountain National Park (BJCMNP), Jamaica’s first terrestrial national park opened in 1993. A proposal exists, under the protected areas system plan, to establish the Port Antonio Marine Park and Forest Corridor (PAMP) which would include approximately 20km of coastline extending from Downer’s Bluff to North East Point. The Corridor would include all the inshore marine habitats from the coast to 200m in depth as well as the interior watershed area draining into the sea between these points, up to the northern boundary of the BJCMNP.
Portland’s inshore marine environment includes a variety of seafloor habitats including corals, algae, sand, and mud plains. Historically the coral reefs in and around the Port Antonio Marine Park site has included some of the healthiest remaining examples in Jamaica and as such is of critical national priority. However, these reefs are under threat from land‐based anthropogenic activities such as the effects of sewage, solid waste, wastewater and
sediment brought to the reef by rivers, runoff and prevailing currents.1
Under the auspices of the Environmental Management Committee of the Drivers River Watershed Management Project a survey was carried out to gather information on the current status of the reefs in eastern Portland to provide up to date data for management action. The coral reef survey was coordinated and implemented by Tracey Edwards, Coordinator for the GEF‐IWCAM Environmental Monitoring Committee. This report present the result of the this survey conducted at fourteen (14) coral reef sites along the east central coastline of Portland during the period July 15 to 24, 2009.
1.2 BACKGROUND
1.2.1 THE GEF‐IWCAM PROJECT
The Integrating Watershed and Coastal Areas Management (IWCAM) Project in Caribbean Small Island Developing States (SIDS) commenced in 2005 and encompasses thirteen (13) participating SIDS. The main implementing agencies for this GEF project were the United Nations Environment Programme (UNEP) and the United Nations Development Programme (UNDP). The National Environment and Planning Agency (NEPA) is the local implementing agency for the Demonstration Project in Jamaica.
Caribbean coastal and watershed systems are among the most productive in the world, yet they are the most threatened, due to rapid land use changes and coastal developments. The GEF‐IWCAM project aims to help mitigate some of the impact of these developments across the Caribbean. The Demonstration Project therefore proposes to develop and implement a model Watershed Area Management Mechanism for the eastern Portland area, incorporating the lessons and experiences gained elsewhere in the country, and capturing relevant examples from other SIDS. The final objective of this project would be to demonstrate an effective mechanism for such a management strategy and to identify where and how this model could be replicated in other areas of the country. The map of Jamaica in Figure 1 shows eastern Portland and the location of the Divers River watershed.

1.2.2 DRIVERS RIVER WATERSHED MANAGEMENT UNIT
The Drivers River Watershed Project is among eight other demonstration projects across the Caribbean. The watershed (Figure 2) which is rated one of the least degraded in the country and was chosen to help develop Best Management Practices in environmental habits and activities. These were identified, planned and implemented through a participatory process involving agency and community partnerships. Four committees were formed to ensure the adaptation and implementation of these practices. These were;
• Governance & Enforcement
• Sanitation and Sustainable Livelihood,
• Environmental Monitoring
• Public Education and Awareness
Stakeholders were given the opportunity to choose the committee they wished to work with, based on special interest or natural talent. All of these committees reported back to the stakeholders at the monthly Stakeholders Meeting.

1.2.3 ENVIRONMENTAL MONITORING COMMITTEE
The main objectives of the Environmental Monitoring Committee were:
1. To capture baseline data for the Watershed 2. To monitor fresh water and marine sites for pollution trends. 3. To assess the status of fresh water and coastal resources and identify keystone species. 4. To identify areas of rich biological significance for conservation and protection. 5. To identify human activities, if any, that negatively impact on the natural resources of the Drivers River
Management Unit and make recommendation/s for mitigation against these harmful practices
Activities included reef assessments, mangrove monitoring/resuscitation, water quality/quantity monitoring, boat tours, household surveys, bio‐monitoring and clean‐ups (beach & community).

1.3 SITE SELECTION AND METHODOLOGY
1.3.1 SITE SELECTION
The site selection process included consultation with the members of the Environmental Monitoring Committee, representatives from the Portland Environmental Protections Associations (PEPA), NEPA and the local dive operators Lady G Divers. Monitoring sites were chosen to be representative of the entire Drivers River watershed and were based on proximity to previous assessment sites (Goreau, 1996). Fourteen (14) sites were selected, four shallow sites (Drapers, Dragon Bay, Pellew Island and Manchioneal Harbour) and ten (10) sites of intermediate depth (Dragon Point, Alligator West, Courtney’s Reef, Fairy Hill, Boston Bay, Policeman’s Harbour, Black River, See Me No More, Banana House and Horse Savannah). The location of the fourteen (14) monitoring sites is shown in Figure 3.
1.3.2 MONITORING METHODOLOGY
The initial monitoring methodology called for five 20m transects to be established at each site, parallel to the shoreline. However due to the bottom topography and reef structure, this procedure was later modified with respect to the individual sites. The methodology was maintained for most sites but where challenges existed, a single 100m transect was employed instead. Where five 20m transects were laid out, they were placed in parallel at a distance of 5m between each transect.
Images were captured along the transect at a height of 1m above the substrate. This distance was maintained with the use of a 1m PVC pipe which supported the diver. Still images was captured at every metre along the transect line. Two cameras with flash attachment were used for image capture these were a Canon Powershot and a Nikon D300 with a wide angle lens. Other equipment employed included a 100m measuring tape, nylon cord, a one metre PVC pipe and a recording slate. The monitoring dives were carried out during the period July 15‐24, 2009. All dives were carried out between 7am and 10am each day.
1.3.3 MONITORING TEAM
The monitoring team included Tracey Edwards, the Team Leader and Project Coordinator for the Portland Environment Protection Association (PEPA) and also the Environmental Coordinator/Community Animator for the IWCAM Project. Other members of the team included Dr. Thomas Goreau, President of the Global Coral Reef Alliance (GCRA) network and a worldwide consultant on coral reef ecology and restoration, Robert Hue of the Jamaica Sub‐Aqua Club (JSAC), Tyrone Brown and Elliot Sykers (Lady G Divers). Nelsia English, Research Officer for the GEF‐IWCAM Project also participated in the monitoring exercise (Plate 1).

1.3.4 DATA PROCESSING AND ANALYSIS
Images in electronic format were submitted to the Centre for Marine Sciences, University of the West Indies (CMS, UWI). A total of 1731 images were analyzed from the fourteen (14) monitoring sites. The random point count method was used to estimate the benthic substrate cover from the images. The Coral Point Count with Excel extensions (CPCe) an automated random point count method designed for the statistical analysis of marine benthic communities (Kohler & Gill, 2006) was used. The CPCe programme was used to randomly overlay 10 points on each image from which the benthic species or substrate category lying under each point was identified. Once identified the codes are entered directly into an associate Microsoft Excel Spreadsheet.
1.3.5 REPORT PREPARATION
This report was prepared by the CMS on the request of the GEF‐IWCAM/NEPA Project and in collaboration with Tracey Edwards, Environmental Coordinator/Community Animator for the GEF‐WCAM Project and Team Leader and Project Coordinator for the Portland Environment Protection Association (PEPA). The report is divided into four sections. Section 1 provides an introduction and background to the project. Section 2 contains the result of the monitoring programme. Section 3 provides some coral reef data from other locations in Jamaica and the Caribbean and Section 4 contains the conclusions and recommendations.

SECTION 2: RESULTS OF MONITORING
2.1 DRAGON POINT
2.1.1 SITE DESCRIPTION AND METHODOLOGY
The monitoring site at Dragon Point was located approximately 100m from the shoreline east of Pellew Island and about 100m from the Blue Logoon Villas. The entry point from land was at the Turtle Cove Beach and the area had an average depth of 13m. Monitoring was conducted on July 15, 2009. Five 20m transects were established and 156 images were taken at 1m intervals using a Nikon D300 camera. Resultant images were submitted in electronic format to the CMS for data analysis.
From general observations the benthic topography was comprised of an undulating terrain, sloping gently to 13m. The benthic substrate was comprised mainly of rocks and rubble with small areas of patch reef. The sandy bottoms consisted of coarse white sand similar to that found on the small adjacent beach. Coral cover was low with the site dominated by a variety of fleshy algal species. Visibility was good and but few fishes were observed. The general appearance of the reef is shown in Plate 2.

2.1.2 DESCRIPTION OF THE BENTHIC SUBSTRATE
At Dragon Point a total of ten (10) coral species were identified and these made up 5.89% of the overall benthic substrate. The most commonly occurring coral species were Porites astreoides and Siderastrea siderea which made up 1.74% and 1.34% of the benthic cover respectively. Other species identified included Agaricia

agaricites(0.67%), Diploria labyrinthiformis (0.13%), Diploria strigosa (0.13%), Meandrina meandrites (0.07%), Montastraea annularis (0.60%), Porites divaricata (0.04%), Porites furcata (0.20%) and Porites porites (0.60%). This site was dominated by various species of macroalgae (83.1%) which included Halimeda (0.54%), Padina (0.07%) and turf algae (3.08%). Also found in the area were gorgonians (0.13%), encrusting sponges (0.74%) and anemones (0.07%). Dead coral and algae (0.87%) as well as recently dead coral (0.07%) were also observed. No diseased corals were observed at this site. Pavement, rubble and sand made up 9.03% of the substrate while 0.20% was unknown. These results are presented in Table 1 and illustrated in Figure 4. Plate 3 shows images of the substrate including selected coral species.

2.9 POLICEMAN'S HARBOUR
2.9.1 SITE DESCRIPTION AND METHODOLOGY
The Policeman’s Harbour monitoring site was located 80m from the shore in water of average depth of 15m. The entry point from land was at Long Road. Monitoring was conducted on July 14, 2009. Five 20m transects were established and 117 images were taken at 1m intervals using a Canon Powershot A540 camera. Resultant images were submitted in electronic format o the CMS for data analysis.
The general benthic topography of the Policeman’s Harbour monitoring site was undulating, with some massive corals interspersed with rocks and rubble. The benthic substrate was mostly algae covered but gorgonians (sea fans and sea whips) were also observed. The visibility at this site was low and there was evidence of high sedimentation, possible as the results of inflows from the Black River. The general appearance of the reef is shown in Plate 18.

2.11 SEE ME NO MORE
2.11.1 SITE DESCRIPTION AND METHODOLOGY
The See Me No More monitoring site was located 280m from shore in water of average depth of 15m. The entry point from land was at the See Me No More River. Monitoring was conducted on July 20, 2009. Five 20m transects were established and 103 images were taken at 1m intervals using a Nikon D300 camera. Resultant images were submitted in electronic format to the CMS for data analysis.
The benthic topography was gently sloping with numerous drop offs. The patch reefs contained large boulder corals, some rocks, rubble, sand patches. Much of the reef was cover with macroaglae and the lionfish was observed in this area. The reef was influenced by the Christmas and See Me No More Rivers which resulted in suspended sediment impacting the reef. Also the currents were very strong in this area. The general appearance of the reef is shown in Plate 22.
Plate 22: See Me No More – image showing the general appearance of the reef.
2.11.2 DESCRIPTION OF THE BENTHIC SUBSTRATE
Coral cover at the See Me No More reef site was low accounting for only 2.76% of the benthic substrate. The seven (7) species identified included Agaricia agaricites (0.92%), Diploria labyrinthiformis (0.10%), Montastraea annularis (0.31%), Montastraea cavernosa (0.10%), Porites astreoides (0.10%), Siderastrea radians (0.20%) and Siderastrea siderea (1.02%).

2.13.1 MANCHIONEAL HARBOUR
2.13.1 SITE DESCRIPTION AND METHODOLOGY
The monitoring site at Manchioneal Harbour was located approximately 200m from shore in shallow water with average depths of 3m. The point of entry for this site was the Manchioneal fishing village. Monitoring was conducted on July 24, 2009. A 100m transect was established at this site and 103 images were taken at 1m intervals using a Canon Powershot A540 camera. The images were subsequently submitted in electronic format to the CMS for data analysis
The benthic topography of the Manchioneal Harbour site was generally undulating and rocky with steep but shallow drop offs. The visibility was generally low as a result of high levels of sedimentation from the Driver River and the currents were very strong. The benthic substrate was comprised primarily of rocks and rubble with some patch reefs, gorgonians and macro‐algae. A few sea urchins (Diadema and Echinometra) and encrusting sponges were observed. The general appearance of the reefs is shown in Plate 26.
Plate 26: Manchioneal Harbour: ‐ image showing the general appearance of the reef.
2.13.2 DESCRIPTION OF THE BENTHIC SUBSTRATE
The reefs at Manchioneal Harbour exhibited low coral cover (4.40%) with only four coral species identified. Diploria strigosa (2.76%) was the most abundant coral species with Diploria clivosa (1.43%), Montastraea annularis (0.10%) and Porites astreoides (0.10%) also present. Gorgonians (0.10%) and encrusting sponges (2.86%) were also observed.

2.14 HORSE SAVANNAH RIVER
2.14.1 SITE DESCRIPTION AND METHODOLOGY
The Horse Savannah monitoring site is located approximately 100m from shore and is found in water of average depth of 13m. Access from land was in the vicinity of the Horse Savannah Bridge at Ennes Bay. Monitoring was conducted on July 21, 2009. Five 20m transects were established and 102 images were taken at 1m intervals using a Nikon D300 camera. Resultant images were submitted in electronic format to the CMS for data analysis.
The benthic topography was relatively flat terrain for several metres with an additional steep drop off for an additional 13m. The area was generally affected by high wave action and strong currents. The substrate contained mainly gorgonians with few boulder corals, and very little rubble. The Horse Savannah River empties into this area which has influenced the benthic community of this reef. The surrounding communities, including Hectors River, are engaged primarily in farming and the residents use the river for various domestic purposes. The general appearance of the reef is shown in Plate 28.
Plate 28: Horse Savannah River – image showing the general appearance of the reef.
2.14.2 DESCRIPTION OF THE BENTHIC SUBSTRATE
A total of nine (9) coral species were identified at the Horse Savannah river monitoring site which accounted for 6.79% of the benthic substrate cover. Agaricia agaricites (1.54%), Porites astreoides (1.23%) Siderastrea siderea (1.85%) and were the most abundant coral species identified. Other species observed included Acropora palmata (0.93%), Meandrina meandrites (0.31%), Millipora complanata (0.10%), Montastraea annularis (0.51%), Montastraea cavernosa (0.21%) and Siderastrea radians (0.10%). Gorgonians (4.32%) and encrusting sponges (2.37%) were also observed at this site along with zoanthids (0.21%) and other live (anemones) organisms (0.21%). Macroalgae made up 81.28% of the benthic substrate and included predominantly turf algae (66.36%) with Dictyota (8.33%), Padina (1.03%) and other macroalgae (5.56%). Dead coral with algae accounted for only 2.57% of the benthic substrate and sand, pavement and rubble accounted for 2.26%. These results are presented in Table 14 and illustrated in Figure 17.

2.15 SUMMARY OF MONITORING RESULTS
2.15.1 CORALS
The level of coral cover ranged from 2.76% at See Me No More to 21.33% at Drapers (Figure 18) with a mean percentage coral cover of 7.82% along the entire east central coastline of Portland. The site at Drapers was distinctive because of the presence of a large number of sea urchins and the absence of extensive macroalgae cover. The See Me No More site was heavily impacted by river run‐off with high sediment content resulting in high algal and low coral cover. Generally those sites with greater external influents had less coral cover.
Figure 18: Comparison of coral cover for the 14 sites monitored along the east central coastline of Portland
A total of 18 coral species were recorded along the east central coast of Portland. The number of species occurring at these sites ranged from four (4) at Manchioneal Harbour to fourteen (14) at Courtney’s Reef (Figure 19). Table 15 below provides a more detailed comparison of the distribution of coral species. The most commonly occurring species were Agaricia agaricites, Montastraea annularis, Porites astreoides, Porites porites and Siderastrea siderea which were found at more than 10 of the 14 sites. While most of the other species occurred at four or more sites… there were four species that occurred at three or less sites. These were Acropora palmata, Eusmilia fastigiata, Madracis mirabilis and Porities furcata. Of significance is the presence of Acropora palmata which has now been designated

2.15.2 MACROALGAE AND DEAD CORAL WITH ALGAE
The occurrence of macroalgae was high and when combined with that dead coral and algae accounted for 68% to 87% of the benthic substrate. O significance was the sites (Pellew Island and Drapers) that had low levels of macroalgae and particularly with respect to drapers had higher coral cover and higher numbers of species. These sites are compared in Figure 20 below, which also shows that the sites with low macroalgae cover had high dead coral with algae values.
Figure 20: Macroaglae combined with dead coral with algae for the 14 monitoring sites along the east central coastline of Portland.
2.15.3 GORGONIANS AND SPONGES
Gorgonians were found at all the stations ranging from 0.10% at Manchioneal Harbor to 8.11% at Boston Bay, with approximately half the sites with gorgonians cover at 2% or, less with the remainder being between 4‐8%. (Figure 21). There were a variety of types that were present including sea fans, sea whips, sea rods and sea plumes. Initial evaluation suggests that the gorgonian cover was less at sites with higher coral cover, but this would have to be further analyzed to determine if there was in fact any correlation.
Figure 21: Comparison of gorgonian cover at the 14 sites monitored along the east central coastline of Portland.

Sponges were also found at all the monitoring sites ranging from 0.61% at Drapers to 6.42% at Banana House (Figure 22). The encrusting sponges were more common and were primarily responsible for the cover found at Courtney’s Reef and Banana House. As with the gorgonians, further analysis would be required to determine any correlation with the abundance of sponges and other benthic substrates.

2.15.4 OTHER BENTHIC SUBSTRATE CATEGORIES
Very few other living organisms (excluding sand, pavement and rubble) were identified at the sites monitored. These included the zoanthids, Palythoa sp, which was identified at five (5) sites and anemones identified at two (2) sites.

SECTION3: STATUS OF CORAL REEFS IN JAMAICA AND THE WIDER CARIBBEAN
3.1 CORAL COVER AT VARIOUS LOCATIONS AROUND JAMAICA
3.1.1 MONKEY ISLAND (PELLEW ISLAND)
Coral reef monitoring studies carried out and reported on for Monkey Island (Pellew Island), 10km east of Port Antonio (Chevannes Creary, 2001; Centre for Marine Sciences, 2006) showed coral cover comparable to those found during this study. The CPACC4 video monitoring protocol was used to conduct the monitoring over the four year period 2000‐2003. Video monitoring was carried out by NEPA while data analysis and report preparation was carried out by the CMS. Table 16, which contains the combined results from the two reports as well as the results of this study, shows that the mean coral cover at Monkey Island (Pellew Island) ranged from 6.23% to 11.80% over the four year period. This result is comparable to the 9.04% coral cover found in this study.
The macroalgae at the Monkey Island (Pellew Island) site ranged from 26.92% to 55.85% over the 2000‐2003 period compared to the low value of 3.15% observed during this study. This contrast with the much lower dead coral with algae values (5.28% to 33.95%) obtained over the four year period when compared to the 83.96% observed during this study. One possible reason for the difference observed could be the presence of the herbivore, Diadema which grazes on the macroalgae. Also, the coralline algae cover was higher, ranging from 5.14% to 23.66% over the period 2000‐2003, while none was observed during this study. The percentage of the substrate comprised of sand, rubble, rock and boulder was also higher during the 2000‐2003 period, ranging from 6.6% to 17.70% compared to 2.60% observed in this study.

3.1.2 ISLAND WIDE REEF CHECK SURVEY
The National Environment and Planning Agency conducted reef assessments of thirty‐six (36) sites island wide during the 2008‐ 2009 period (NEPA, 2009). The Reef Check protocol was used to document the conditions of the reefs and included sites within designated protected areas as well as areas slated for development. This survey showed that the Jamaican reefs exhibited variable coverage as it related to the benthic substrate. The hard coral cover ranged from 1.88% at El Punto Negrilo in Westmoreland to 38.13% at Dairy Bull in St Ann (Table 18). The overall mean percentage cover of hard corals for the island was 13.7%. When compared on a parish basis (excluding St Elizabeth, Manchester, Clarendon and St Thomas), St Ann recorded the highest mean coral cover of 20.83% while the lowest was recorded in St Catherine. The parish of Portland had a mean percentage coral cover of 9.50% which was the second lowest of the parishes assessed.

The assessment identified over thirty (30) species of corals with an average of 16 recorded per site. Eighteen (18) species were recorded for this study with an average of 16 per monitoring site. The coral species identified included Acropora palmata and Acropora cervicornis, both restricted to the north coast. The most commonly occurring species were Agaricia spp, Montastraea spp, Porites spp, Siderastrea spp, Diploria strigosa, Meandrina meandrites, Colpophyllia natans and Millipora complanata. All but A. cervicornis and C. natans were observed during this study.

3.2 CORAL COVER IN THE WIDER CARIBBEAN
3.2.1 THE EASTERN CARIBBEAN
As with other countries within the region the reefs in the Eastern Caribbean have been exposed to a variety of local ( eg pollution and sedimentation ) and regional (eg bleaching as a result of elevated sea surface temperatures) threats. Coral reef monitoring was conducted in seven (7) islands in the Eastern Caribbean (Antigua, Dominica, Grenada, St Kitts, St Lucia, St Vincent and Tobago) as part of the MACC (Mainstreaming Adaptation to Climate Change) project (Creary, 2008; Creary, 2009). Under the mandate to build capacity the MACC project undertook to strengthen the climate change and coral reef monitoring network in the region. The programme involved coral reef monitoring on two occasions for each country over the period 2007‐2009. The results of the monitoring showed that for all the islands the macroalgae combined with dead coral with algae accounted for the largest component of the reef benthic substrate. Hard coral cover ranged from 3.80% in Antigua (2008) to 29.18% in St Vincent (2007). Dominica, Grenada, St Kitts and St Lucia all had mean percentage coral cover at or around 10%. The reefs in St Vincent and Tobago showed higher levels of coral cover with the maximums of 29.18% and 15.88% recorded in each country receptively. The summary of these results are provide in Table 19 below.
During the monitoring programme a total of thirty (30) coral species were identified. The most abundant and widely distributed species identified during this monitoring programme were Porites astreoides, Montastraea annularis and Siderastrea siderea which were observed in all seven countries. Also observed in all countries but in less abundance were Agaricia agaricites, Diploria labyrinthiformis, Diploria strigosa, Madracis mirabilis, Meandrina meandrites, and Montastraea cavernosa.

3.2.1 STATUS OF CORAL REEFS IN THE WIDER CARIBBEAN.
Gardener et al (2005) evaluated 263 sites from 65 separate studies in the Caribbean over the period 1977 to 2001. The results showed a massive regional wide decline of corals with the average hard coral cover on the reefs declining from 50% to 10% (Figure 23). The study suggested that the loss in coral cover in Jamaica was due to the interaction of a number of stressors including Hurricane Allen in 1980, the onset of white band disease of Acropora palmata and the mass mortality of the sea urchin Diadema antillarum. The recent decreases in the rate of loss in coral cover may be signaling the recovery of Caribbean reefs but observations indicates that a shift in community structure has taken place. The once dominant frame builders (Acropora and Montastrea) have been replaced by non‐reef building forms (Agaricia, Porites and sponges) which as opportunistic species ,might not be able to withstand the predicted impacts of climate change such a rising sea levels and increasing sea surface temperatures.

SECTION 4: CONCULSIONS AND RECOMMENDATIONS
4.1 CONCLUSIONS
This report presents the data collected from the fourteen (14) sites along the east central coastline of Portland, extending from Dragon Point to Horse Savannah River. Below are presented the preliminary conclusions drawn from these data. Further analysis of the data and the images would be required to establish trends as it relates to geographic location, exposure of site, land based influences and any other factors that might influence benthic substrate composition.
1 The mean percentage coral cover at the fourteen (14) sites surveyed ranged from 4.83% to 21.33% with a mean percentage cover of 7.82%. This compares to the mean for Jamaica of 13.7% (NEPA, 2009), the Eastern Caribbean of 12.14% (calculated from Table 19) and the Wider Caribbean of 10% (Gardener et al, 2003).
2 The coral species observed at the sites is eastern Portland were similar to those identified in the rest of Jamaica, the Eastern Caribbean and those highlighted by Gardener et al (2003) for the Wider Caribbean. Although the traditional frame building corals such as Montastraea was observed the reefs tended to be dominated by non‐frame building encrusting and branching species such as Agaricia, Porites and Siderastrea.
3 The reefs at all except two sites (Pellew Island and Drapers) were dominated by macroalgae. Where macroalgae was not present the reef was predominantly covered with dead coral with algae. It appears that those sites at which sea urchins were observed in large numbers had the least amount of macroalgae.
4 The high sedimentation observed on some reefs appeared to be associated with sites that were in close
proximity to freshwater runoffs and/or upwelling. These sites were also associated with low coral and high macroalgae cover.
4.2 RECOMMENDATIONS
1. Surveys conducted by the Portland Environment Protection Association between March 2006 and January 2007 (PEPA, 2007) indicate that degradation on coral reefs in parts of Portland are direct and indirect consequences of human actions. It is therefore recommended that the relevant authorities which include the National Environment and Planning Agency (NEPA), the Solid Waste Management Authority (NSWMA), the Portland Parish Council Department (PPDC) collaborate with the local NGO (PEPA), the Social Development Commission and the CDC’s within the respective areas to find a solution that will reduce the effects of individual and community base actions that contribute to coral reef degradation.
2. Zoning of sections of east Portland will aid in the conservation and restoration of reefs that have potential for growth and maintenance. Zoning should include interrelating habitats such as Turtle Crawl and Manchioneal Mangrove Forest. Coral reefs that are least degraded and have potential for conservation and restoration should be at the top of the list and slated priority sites for preservation actions. These sites include Drapers, Pellew Island and Dragon Bay.
3. The importance of enforcing environmental laws cannot be overly emphasized. But without support from the governing bodies, human actions that results in damage to the reefs will continue. The National Solid Waste Management Authority and the Fisheries Division of the Ministry of Agriculture should ensure that the proper sanctions are carried out with respect to misuse and overuse of resources. The NSWMA should in respect to
Caribbean Coastal Data Centre, Centre for Marine Sciences, UWI 70
solid waste, enforce the laws to deter illegal dumping practices that would consequently impact on reef conditions.
4. The Drivers River Watershed is located east of Port Antonio; the fourteen sites assessed were confined within this area. This area receives the least interventions of the five watersheds located in the parish: it is therefore recommended that projects with an integrated approach to management of ecosystems be continued for longer than 18 months to ensure full participation, management and monitoring of the natural environment.
5. Since sedimentation has a significant effect on coral recruitment and preservation it is recommended That the Rural Agricultural Development Agency become more involved in agricultural practices and farm structures, ensuring that all registered farmers within the Drivers River Watershed follow a standard that will limit soil erosion and sedimentation in rivers and consequently the coral reefs.
