U.S. Virgin Islands – MPA Management


How do we use our Marine Space? Mapping Human Uses of the East End Marine Park

Location
St. Croix, U.S. Virgin Islands

The Challenge
The St. Croix East End Marine Park (STXEEMP) is the U.S. Virgin Islands’ first and largest marine protected area. Its waters are cherished for a variety of commercial and recreational uses by fishers, recreational boaters, charters, hotels, and marinas. The Park also contains extensive mangroves, seagrass beds, coral reefs, sea turtles, beaches, and fish species, which provide invaluable ecosystem benefits. While the extent and health of the biological resources are well understood, human use and social dimensions of the Park are not well researched or documented.

A central objective of marine spatial planning (MSP) is the identification and reduction of conflicts among human uses, and between human uses and the environment. In order to achieve this objective, it is necessary to have accurate and thorough spatial data representing both important and sensitive benthic habitats as well as the location, temporal distribution, and intensity of human activities. Unlike datasets related to physical and biological information, coastal human use information is less common in geographic information systems (GIS). However, collecting and putting this information into GIS allows for it to be visualized and analyzed for the purpose of MSP and management. This project filled those human activity data gaps through a coastal use mapping project.

With support from the National Oceanic and Atmospheric Administration’s Coral Reef Conservation Program (NOAA CRCP), The Nature Conservancy (TNC) and the Virgin Islands Department of Planning and Natural resources (USVI DPNR) convened partners and stakeholders to conduct the STXEEMP Coastal Use Mapping Project. Designed to collect information on how a community is using a coastal or marine area, a representative group of stakeholders were invited to provide input on how they use the waters and coastal areas of the Park. In order to ensure accurate representation from users of the STXEEMP, project partners assembled a list of every human activity within the STXEEMP. Key stakeholders from each activity were invited to workshops to represent their knowledge of that activity. This data will help resource managers understand both the range and intensity of key activities.

Workshops were held with stakeholders on St. Croix on April 16 and 17, 2015, to map key uses in the coastal environment, with a particular focus in the St. Croix East End Marine Park. Representatives from different marine sectors (recreation, watersports, marina, charter boating, SCUBA diving, and fishing industries) as well as NGOs and territorial and federal governmental partners met to provide first-hand information on the spatial and temporal distribution of human use activities in nearshore areas of USVI.

This information was captured using the method of “Participatory GIS Mapping.” Participatory mapping provides participants a map on which to indicate the location of their activities, while moderators generate representative spatial data files in real time. E-Beam™ technology, an interactive tool that allows users to draw electronically on a map, was used to aid the participatory mapping method. During the workshops, maps of the STXEEMP were projected on the wall in front of the group. Representative stakeholders of each activity (i.e. snorkeling) walked to the front of the room and electronically mapped the location while the group provided input.

This work represents an ongoing effort by TNC, USVI DPNR, NOAA CRCP, and members of the Caribbean Regional Ocean Partnership (CROP) to update human use data throughout the USVI in support of resource managers and regional MSP.

How Successful has it been?
The following human activities and subsequent mapping layers were created during the STXEEMP Human Use Mapping Workshop in April 2015:

  • Boat Ramps and Slips
  • Marinas
  • Moorings
  • Recreational and Commercial Boating
  • Motorized and Non-motorized Personal Watercraft
  • Dive and Snorkeling Sites
  • Marine Restoration
  • Camping Beach Areas
  • Fish and Conch Fishing Area
  • Surfing

Data collected during the mapping workshops has been made available to workshop participants on the CROP Data Portal to the general public and resource managers as maps, GIS mapping layers, and analytical products reflecting the variety and extent of ocean uses. The summary report will be available electronically at reefconnect.org. Where possible, layers were combined to create a regional file for the entire territory of the USVI.

These data are available to local and regional managers for the purposes of marine spatial planning, management, conflict reduction amongst user groups, and resource protection.

Lessons Learned and Recommendations
In order to conduct a participatory mapping process, several key factors come into play including:

  • Participatory mapping depends on human resources and knowledgeable stakeholders must attend workshops and share their valuable information on human activities. Effort should be put towards recruitment of these stakeholders.
  • Technical resources including personnel that can manipulate GIS spatial files is critical.
  • Base maps of existing data are critical to getting accurate results.
  • E-Beam™ technology facilitates the collection of real time data in a participatory manner.

Funding Summary
This project was conducted by The Nature Conservancy with support from the National Oceanic and Atmospheric Administration’s Coral Reef Conservation Program (NOAA CRCP) through Cooperative Agreement #NA13NOS4820145. Through this Partnership, TNC and NOAA work on site level management and conservation strategies for the STXEEMP. The STXEEMP management and staff supported the project by identifying stakeholders, creating outreach materials and advertising the event.

Minimizing the Short-Term Impacts of Marine Reserves on Fisheries While Meeting Long-Term Goals for Recovery

No-take marine reserves are often proposed as management tools to recover small-scale fisheries, which, if enforced, can improve mid to long-term harvests and profits. However, the short-term losses may prevent fishers from supporting and implementing no-take reserves, resulting in a loss of recovery of fisheries. Trade-offs between short-term loss in profits and long-term benefits to small-scale fisheries were quantified, using a multispecies model of coral reef fisheries for one case study. Impacts of reserves at different time scales depend on the social and management context, but the key to gaining support for marine reserves is to quantify the trade-offs at different time scales for stakeholders and policy makers. Policies for implementing marine reserves that are flexible can offer options with less short-term losses for fisheries that can be more appealing to fishermen, while still reaping the long-term recovery benefits.

The Micronesia Challenge: Assessing The Relative Contribution Of Stressors On Coral Reefs To Facilitate Science-To-Management Feedback

The Micronesia Challenge is an international conservation strategy initiated by the political leaders of 6 tropical island nations to conserve at least 30% of marine resources by 2020. Growing population and a shift towards cash-based economies have started to erode the traditional sources of sustainable reef management and have increased pressure upon marine resources. This study examined the effects of human populations on the diversity, function and status of coral reef ecosystems across Micronesia by assessing ecosystem condition to evaluate conservation goals of the Challenge, examining the distribution and variance of ecosystem condition as indicators of ecological stability and looking at the role of two stressors – fishing and pollution – in driving ecosystem metrics. Results showed that fishing pressure was a primary determinant of ecosystem condition across the majority of locations studied. Reef habitats that were most impacted by localized stressors also had the least stable ecosystem condition scores. In conclusion, habitats close to urban centers may require more management effort and may show less of a positive response to management than distant sites. Also, fish assemblages appeared to have a hierarchical influence upon coral-reef ecosystems compared with localized pollution. Prioritizing management upon herbivore size and diversity may best preserve the trophic relationships responsible for ecosystem services that coral reefs provide to the Micronesian island nations.

Evaluating The Relative Conservation Value Of Fully And Partially Protected Marine Areas

Marine protected areas (MPAs) offer various states of protection and are often viewed as a conflict between conservation and fishing. This study synthesized research that compared partially protected areas (PPAs), no-take reserves (NTRs) and open access areas (Open), to assess the potential benefits of different levels of protections of fish populations. Response to protection was examined in relation to MPA parameters and the exploitation status of fish. 40 relevant studies were included in the meta-analysis. The results suggested that PPAs significantly enhance density and biomass of fish relative to Open areas. NTRs yielded significantly higher biomass of fish within their boundaries relative to PPAs. The authors conclude that MPAs with partial protection confer advantages, such as enhanced density and biomass of fish, compared to areas with no restrictions. The strongest responses occurred for areas with total exclusion. MPAs with a combination of protection levels are a valuable spatial management tool especially in regions where stopping all activities is not politically and socio-economically viable.

Marine Zoning In St. Kitts And Nevis: A Design For Sustainable Management In The Caribbean

This paper details a marine zoning process for the island nation of St. Kitts and Nevis in the Eastern Caribbean, incorporating the use of marine spatial planning (MSP) and marine zoning to address multiple uses in the same ocean space. Multiple uses include coastal protection, food security, tourism amenities, biodiversity protection and climate change adaptation. MSP is an approach facilitating a balanced co-existence between marine sectors with competing interests and attempts to combine marine management strategies by describing the local context, outlining key activities and discusses planning process outcomes. Key activities include engaging stakeholders, establishing clear objectives, building a multi-objective geodatabase, generating tools to assist stakeholders and decision makers consider zoning plan options and using a participatory process to outline zone locations. The paper concludes that this approach helped provide an integrated view of marine space and uses for St. Kitts and Nevis and the stakeholders were able to develop a shared vision for their waters. There were also challenges throughout the MSP process and lessons learned were generated to help improve future marine planning and zoning process.

The Intrinsic Vulnerability To Fishing Of Coral Reef Fishes And Their Differential Recovery In Fishery Closures

Coral reef fisheries play a role in livelihoods and local economies around the world, but the impacts of fishing on targeted species of reef fish is poorly understood. The authors of this study examined the vulnerability of different species of coral reef fish to fisheries and evaluated the effectiveness of no-take reserves and periodically-harvested closures. Using life history traits to characterize the vulnerability of fish species to fishing, they found that larger-bodied carnivorous fish have a higher vulnerability compared to smaller-bodied herbivores and detritivores. In no-take areas, moderately to highly vulnerable species take a significantly longer time (decades) to recover than less vulnerable species. Based on these findings, they make the following recommendations for managers:

    • Expand studies of reef fish to improve estimates of vulnerability; Maintain long-term (20-40 year) no-take areas for full population recovery
    • Enforce compliance of no-take areas
    • Control timing and intensity of periodic closures for long-term fishery benefits
    • Use periodic and closures and no-take areas together as fishery management tools

Micronesia – Predator Outbreaks


A Well-Developed Community-Based Marine Protected Area Proves Resilient to a Crown-of-Thorns Sea Star Outbreak

Location
Nimpal Channel Marine Conservation Area, Yap, Federated States of Micronesia

The Challenge
Yap State is situated in the westernmost region of the Federated States of Micronesia (FSM). The main island of Yap State is located within the Indo-Pacific center of biodiversity. The island is approximately 100 square kilometers, with a densely vegetated and hilly landscape. It is home to 7400 residents spread over 10 municipalities, a relatively small population compared to the other states of Micronesia. The population and urban center are slowly growing, placing increasing pressure on the islands’ natural resources for subsistence and economic gain.

The Nimpal Channel is located off the central-western coast of Yap. Both Okaw and Kaday villages have their fishing grounds associated with the Nimpal Channel. The villages are within the municipality of Weloy, home to approximately 1000 residents. In 2005, a men’s village meeting was called to address the ongoing problem of overfishing in their channel, and decided to seek help and information from outside their community. In 2006, a rapid ecological assessment (REA) was conducted across Yap Proper, including the Nimpal region, so that stakeholders could get a better sense of the current status of their resources. The coral-reef monitoring and assessment team for the REA process consisted of many knowledgeable fishermen from Okaw and Kaday villages, as well as regional scientists with local and global expertise. Following data collection and reporting efforts, and realizing that Nimpal’s resources were not as well off as many other places in Yap due to both natural causes and local fishing pressures, these two villages began discussing their desire to set aside part of their reefs as no-take fishing areas.

While the Nimpal Channel is very narrow (approximately 0.5 kilometers in width) and has only a limited mangrove stand associated with it, the two communities proposed to make it a Marine Conservation Area (MCA). Through the REA process, marine scientists recommended areas for protection that were larger, deeper, and had more extensive connections with nearshore mangrove habitats known to nourish juvenile fish populations. To marine scientists, the area that Okaw and Kaday proposed to set aside was clearly influential for the locally-owned marine resources, yet was smaller in size and harbored less biological diversity in comparison to other larger and more extensive channel systems nearby. In short, this was not the most ideal area to bolster fishery resources based upon ecological criteria alone. However, the timing was right, and the two communities strongly supported management in that area. Shortly after, in May 2008, Okaw and Kaday, in partnership, publically declared the Nimpal Channel as a Marine Conservation Area with technical support from the Yap Community Action Program.

Within only 1-2 years, monitoring results began to document improved fishery resources in the conservation area. These positive results were an immediate testament to strong community support for management, and dedicated local enforcement. Four years after formalizing the Nimpal Channel Marine Conservation Area, in 2012, a more formal scientific assessment of the channel reefs highlighted that the reef’s condition is second-highest among other MCAs in the region despite having one of the smallest extents. The MCA exceeded the expectations of many marine scientists and changed the way they thought about establishing new marine protected areas going forward. In this case, strong social acceptance and enforcement was more important than ecological criteria.

In late spring 2009, Acanthaster planci, commonly known as the crown-of-thorns sea star (COTS), began populating the coral reefs around Micronesia (from Pohnpei westward to Yap). A. planci is a carnivorous species of starfish that preferentially preys upon hard corals such as Acropora spp. and Montipora spp. A. planci were first quantified in monitoring programs off the southwest coast of Yap, and anecdotal reports from fishermen and data suggested a northward migration up the west coast of the island.

Actions Taken
Healthy coral reef systems with high levels of fishery resources have been shown to be resistant to the threat of an A. planci outbreak based upon recent evidence from places like the Great Barrier Reef and Fiji. While the exact mechanism remains elusive, there appears to be some added resistance to these natural disturbance events from healthy fish populations through predation and/or other biological interactions. Reefs that have already been stressed by increased sedimentation, reefs with low numbers of predators due to overfishing, and reefs with low coral diversity have proven most vulnerable to A. planci predation.

This outbreak of A. planci was not a new threat for Yap. A. planci outbreaks have been described as natural, cyclical events. There are a few theories on why the outbreaks occur. Some experts theorize that COTS outbreaks occur when the sea stars ‘sense’ oceanic conditions are most conducive for their larval offspring to successfully develop, and hence the initial outbreaks may be triggered by some form of nutrient enrichment in the surface waters near coral reefs. Following spawning from initial population outbreaks, it has also been hypothesized that larvae may get caught in ocean currents and somehow influence secondary starfish outbreaks downstream. In Yap, the single most significant COTS event was documented in the early 1970s, although there is local knowledge of smaller outbreaks over the years.

To the local community, the sea stars are well known, but their lifecycles remain mysterious. Locals understand the origins of threats to the reefs like bleaching, sedimentation, and overfishing; however outbreaks of the crown-of-thorns sea stars just suddenly occur without any obvious proximal cause. During the 2009 A. planci outbreak there was no official attempt on Yap to remove the sea stars from their reefs, but fishermen noted their presence. In the case of the Nimpal MCA, the communities did not choose to remove starfish because of adherence to the established no-take MCA policy.

How Successful Has it Been?
The recovery of the coral reefs to the A. planci outbreak in Yap varied. A recent study revisited the study sites where coral populations were monitored as part of the 2006 REA survey and found interesting results. Many reefs along the western coast of Yap showed an expected decline in coral colony sizes and diversity, yet there was one unique exception. The Nimpal Channel MCA appeared to be more resilient to the disturbance event compared with sites to the north and south of this channel. Remarkably, no sea stars were found in the protected area during surveys shortly after the COTS event. In fact, monitoring of the area during the disturbance revealed an increase in coral colony sizes, no significant change in diversity within coral groups, and consistently high fish biomass. Reefs in the protected area showed high abundances of Porites spp. (the less desired coral for A. planci) but Acropora spp. also remained throughout the disturbance period. The area’s resistance to COTS is hypothesized to be due to an intact predator fish population and high coral diversity.

In contrast, formerly diverse reefs with extensive coral growth, such as off the southwestern tip of Yap, had the greatest coral reef damage after the sea star outbreak, with little recovery reported as of 2013. Other coral reefs to the north of the Nimpal Channel MCA started to recover in 2012, but recovery has been a slow process and remains ongoing. These findings suggest that the establishment of the locally-managed MCA may have benefitted the resilience of Nimpal’s reefs, and might be supporting recovery along adjacent reefs.

This case study highlights the importance of well-managed marine protected areas for weathering disturbance events. Nimpal Channel MCA appeared to provide added resistance to the COTS disturbance through a series of highly influential, but still poorly understood, ecological processes.

While the Nimpal Channel MCA was initially established to aid fish stock recovery, it was later found to have added benefits of enhanced resistance to COTS. The success of the Nimpal Channel Marine Conservation Area in both enhancing fish populations and mitigating the damage done by the 2009 disturbance continues to be a very popular and productive discussion at regional management meetings across Micronesia. This example shows that marine protected areas have additional benefits that we are only beginning to understand. Certainly the list of benefits will grow into the future.

Lessons Learned and Recommendations
People, rather than biology and science, are most important to think about when establishing a marine protected area. Without the community’s dedication to protecting their channel, the Nimpal Channel Marine Conservation Area would never have been established. Based on biological considerations and the small size of the managed area, scientists felt other areas were better suited to set aside as a protected area; it was only through the community’s will and support that their protected area was established. Science is used to drive management recommendations, but other factors might be more relevant for successful management.

The success of a marine protected area is dependent on community involvement and knowledge. The success of the Nimpal Channel MCA is due to community-based decisions based in traditional ecological knowledge and supported by scientific measures. Consequently, the Nimpal Channel MCA is one of the few functioning protected areas in Yap.

Quantitative monitoring is essential for responding to increased frequency and intensity of disturbances. Identify critical biological thresholds in your management area. Reef ecosystems are complex systems that can behave in a non-linear manner (for instance, the decline of a predator fish population might not have the effect of reducing a reef’s resistance to an A. planci outbreak until the predator fish population declines past a critical threshold). Part of this non-linear behavior is related to trophic interactions (interactions between predators and prey, for example). Science has not fully explained trophic interactions and thresholds in coral reef systems. Disturbances are becoming more and more frequent; there might be a COTS outbreak one year and a bleaching event the next year. Because of the increasing frequency and severity of threats to coral reefs, it is important to collect quantifiable data to be able to perceive rates of change. For example, monitoring fish biomass in your area can be a good starting point to understanding how fish biomass is related to reef resilience. The relative level of biomass within different trophic levels may be related to the maintenance of coral reefs through time.

Recovery Potential Of The World’s Coral Reef Fishes

Fishing is the primary source of reduced reef function globally. Marine reserves are a critical tool to help fish populations recover, however, there are no benchmarks to determine if the protection is effective, or whether a reserve has recovered enough to be fished again. By studying remote and marine protected areas, they estimate how many fish would be on a coral reef without fishing, and how long it should take newly protected areas to recover. This helps to assess the impact of reef fisheries, and make informed management decisions that include timeframes for recovery.

Specifically, this paper presents the first empirical estimate of coral reef fisheries recovery potential, compiling data from 832 coral reefs across 64 localities (countries and territories. The authors estimate the expected density of reef fish on unfished reefs; quantify the rate of reef fish biomass recovery in well-enforced marine reserves; characterize the state of reef fish communities within fished and managed areas; predict the time required to recover biomass and ecosystem functions; and explore the potential returns in biomass and function using off-reserve management throughout the broader reefscape. The research team studied the fish biomass on coral reefs around the world and discovered that near-pristine reefs contain 1,000 kg of fish per hectare. Using this figure as a benchmark, they found that 83% of fished reefs have lost more than half of their fish biomass (volume of fish).

The authors discuss how reef fish populations were better off when fishing activities were restricted (e.g., including limitations on the species that could be caught, the gears that could be used, and controlled access rights). The authors determined that once protected, fished reefs take about 35 years to recover, while heavily depleted reefs take almost 60 years. Although the influence of marine reserves can be detected within several years, this global analysis demonstrated that full recovery of reef fish biomass takes decades to achieve. Importantly, this suggests that most marine reserves implemented in the past 10–20 years, will require many more years to achieve their recovery potential. This has important implications for managing expectations of MPAs and also reinforces the need for continued, effective protection and consideration of other viable management options. The authors also found that in reef areas where MPAs cannot be implemented, a range of fisheries can have substantial effects on fish functional groups that support important reef processes.

Towards A Network of Locally Managed Marine Areas (LMMAs) In The Western Indian Ocean

This study describes the increasing use of community based management of marine resources in the Western Indian Ocean (WIO) and assesses locally managed marine areas (LMMAs), producing the first regional inventory. LMMAs are managed for sustainable use and utilize a combination of management tools; in this paper their geography, number, size, and governance structure were described and they were compared to areas managed by government initiatives. A synthesis of the 74 coral-related marine protected areas (MPAs) in eleven countries/territories within the WIO found only 29.6% to be ecologically effective.  Approximately 7% of the regions’ continental shelf receives protection, with 76% of reefs at risk from local threats, the most predominant of which was overfishing. This study also evaluated the potential for MPAs to contribute to the Convention on Biodiversity Target protecting 10% of coastal and marine ecosystems by 2020. Overall, LMMAs in 4 of the 11 countries/territories surveyed have the legal structures to support community-based management, which is lacking in the remaining 7 countries/territories. For LMMAs to be more effective, authors suggest the establishment of a network for LMMA practitioners in the region.

Marine Protected Area Networks: Assessing Whether the Whole is Greater than the Sum of Its Parts

This study looks at whether MPAs in a given network have synergistic benefits on ecological, economic, and social management levels. A proposed analytical framework assessed whether ecological effects across entire an MPA network are greater than the sum of the effects occurring within each individual MPA and evaluates an MPA network in Hawai’i using monitoring data. The West Hawai’i network analyses consists of nine MPAs along with eight smaller, pre-existing protected areas that protect 35% of the coast from aquarium trade fishing. In order for MPA networks to be effective it was established that quantitative monitoring for indicators (biological, ecological, socio-economic, etc.) should be evaluated inside and outside the MPA network before and after MPA establishment. Planning processes should involve all players (managers, scientists, stakeholders) to determine desired goals of the MPA network as well so that monitoring programs collect relevant data to speak to those goals.
