Effective Area-based Conservation Measures Research Articles

Establishing a protected area network in Xinlong with other effective area-based conservation measures.

Protected areas (PAs) are pivotal to biodiversity conservation, yet their efficacy is compromised by insufficient funding and management. So-called other effective area-based conservation measures (OECMs) present a paradigm shift and address PA limitations. Such measures can expand conservation areas, enhance connectivity, and improve the existing system. To assess the conservation status of biodiversity in Tibetan cultural areas in China, we investigated the spatial distribution of wildlife vulnerable to human disturbance (large- and medium-sized mammals and terrestrial birds) in Xinlong, a traditional Tibetan cultural area. In particular, we compared a PA (Xionglongxi Nature Reserve) and OECMs targeting species conservation. We also investigated the relationship of wildlife with human temporal and spatial activities. The OECMs complemented areas not covered by PA, especially in rich understory biodiversity regions. More species in OECMs tolerated human presence than species in the PA. Existing biodiversity reserves failed to cover areas of high conservation value in Tibet and offered limited protection capacity. Expanding PAs and identifying OECMs improved Xinlong's system by covering most biodiversity hotspots. Building on the tradition of wildlife conservation in Tibet, harnessing OECMs may be an effective means of augmenting biodiversity conservation capacity. We recommend further evaluation of OECMs effectiveness and coverage in Tibetan area as a way to enhance the current PA system.

A cost-effective approach to identify conservation priority for 30 × 30 biodiversity target on the premise of food security

There is a growing consensus on expanding protected and conserved areas for biodiversity conservation. Nevertheless, it remains uncertain where to expand conserved areas as well as what appropriate management modalities to choose. Moreover, conserved areas expansion should be balanced with crop-related food security challenges. We developed a framework to identify cost-effective areas for expanding protected areas and other effective area-based conservation measures (OECMs), and applied it to China. By combining templates for biodiversity conservation priorities at global scale and the priority conservation areas based on 2413 vertebrates' extinction risk in China, we identified areas with high biodiversity conservation value. We then categorized the priority areas according to human impact, indicating the potential cost of management. As a result of combining the two aspects above, we identified the most cost-effective areas for expanding protected areas and OECMs while excluding both the current and predicted croplands that can be used for food security. The results show that China could expand its protected areas to 22.81 % of the country's land area and establish OECMs in areas accounting for 9.82 % and 17.37 % of the country's land area in a cost-effective approach in two scenarios. In the ambitious scenario, protected and conserved areas would account for a maximum of 40.18 % of terrestrial area, with an average 62.67 % coverage of the 2413 species' suitable habitat. To achieve the goals of protected and conserved areas in Kunming-Montreal Global Biodiversity Framework, countries could apply this framework to identify their protected areas and OECM expansion priorities.

Other Effective Area-Based Conservation Measures (OECMs) in Australia: Key Considerations for Assessment and Implementation

Other effective area-based conservation measures (OECMs) have been a feature of global biodiversity targets since 2010 (Aichi Targets, Kunming-Montreal Global Biodiversity Framework), although the concept has only relatively recently been formally defined. Although uptake has been limited to date, there is much interest in identifying OECMs to contribute to the target of protecting at least 30% of terrestrial, freshwater and ocean areas by 2030, in conjunction with protected areas. Australia has a long history of protected area development across public, private and Indigenous lands, but consideration of OECMs in policy has recently begun in that country. We review principles proposed by the Australian Government for OECMs in Australia and highlight where these deviate from global guidance or established Australian area-based policy. We examined various land use categories and conservation mechanisms to determine the likelihood of these categories/mechanisms meeting the OECM definition, with a particular focus on longevity of the mechanism to sustain biodiversity. We identified that the number of categories/mechanisms that would meet the OECM definition is relatively small. A number of potentially perverse outcomes in classifying an area as an OECM are highlighted in order to guide proactive policy and program design to prevent such outcomes occurring.

Use of ecosystem services and land ownership to prioritize conservation areas on Jeju Island, Republic of Korea

In the face of ecological challenges, sustainable implementation of conservation strategies necessitates a delicate balance between ecosystem services, biodiversity, land ownership, and cost considerations. This study presents a conservation strategy for Jeju Island, Republic of Korea, an area renowned for its unique ecological features. We developed the strategy by evaluating 12 scenarios involving the establishment of protected areas (PAs) and the use of other effective area-based conservation measures (OECMs). The purpose of this evaluation was not to enhance ecosystem services and biodiversity directly but rather to identify strategies that could achieve these goals in a financially feasible way, considering the various cost and land ownership factors. Our findings revealed that conservation prioritization targets are primarily located in the central and eastern regions of Jeju Island, where ecosystem services are concentrated, and levels of biodiversity are high. The expansion of conservation targets from 17% to 30% entailed increased costs, largely due to the increased inclusion of private lands and agricultural areas. The introduction of OECMs provided a means to improve ecological network and representation within conservation networks. We also found that applying penalties to improve the boundary lengths of PAs could lead to more cost-effective conservation strategies. Although expanding conservation targets to 30% led to significant shifts in land ownership patterns and increased conservation costs, the benefits to biodiversity and provision of ecosystem services were substantial. This study provided valuable insights into the determination of conservation planning through the harmonization of biodiversity prot ection, provision of ecosystem services, and consideration of economic costs related to patterns of land use and ownership. The results can aid policymakers and stakeholders in making informed decisions about resource allocation in biodiversity conservation.

Examination of Neediness of Other Effective Area-based Conservation Measures in Conservation of Threatened Migrant Birds and Breeding Residents in Sri Lanka

Sri Lanka offers habitats to 522 avifauna species at present, including 278 migrant species. Many migrant species are waterbirds and 75% of migrants depend on Sri Lankan w Sri Lanka is a party to the Convention on Biological Diversity and has legal obligations to conserve biodiversity. Except for the migratory avifauna, the bird species in schedule IV of the Flora and Fauna Protection Ordinance receive legal protection outside PAs. Sri Lanka is also a party to the Convention of Migratory Species (CMS) which holds states responsible for the protection of migrant species, however, according to the National Report–2019, No arrangements and agreements affecting migratory species changed recently, and no waterbirds are included in Appendix I. Against this backdrop, the objective of the study was to examine the appropriate and effective conservation approach. Gangewadiya area in the Lower Kala Oya Basin in Puttalam is one of the four richest waterbird regions in Sri Lanka having ideal habitat for migratory waterbirds, was selected as the study area to examine the neediness for other area-based conservation measures. The study was limited to the threatened, migratory avifauna species, and desk review, conceptual modeling, and Pressure-State-Response methods were chosen to identify and analyze threats and responses. The Biodiversity Baseline Survey Report, 2017; reported 39 Migratory Birds (M) and 142 Breeding Residents (BR) including 03 Critically Endangered (CR), 01 Endangered (EN), and 02 Vulnerable (VU) species in the study area. Sterna Nilotic Gmelin, 1,789, Sterna albifrons Pallas, 1,764, and Merops philippinus Linnaeus, 1,766 are BR & M, CR species, not found in Appendix II of CMS. Falco tinnunculus is an Uncertain M, EN found in schedule IV of FFPO, while mentioned in Appendix II of CMS. Charadrius dubius and Charadrius alexandrines are BR & M, VU is identified as the Appendix II taxa for which Sri Lanka is a Range State that demands international cooperation for conservation. These threatened, migratory/breeding residents range not managed as PAs and are adversely impacted due to conversion of land uses, changes in salinity, hydrology, water pollution, and expansion of prawn and salt production. This poses threat to species already nationally threatened, and species called for international obligation for conservation; since disturbances in strategic points along the flyways, breeding, and wintering grounds can badly affect them. Therefore, Other Effective Area-based Conservation Measures are required to minimize the key threat to ranges of migratory birds and breeding residents of Sri Lanka.

The contribution of private land conservation to 30x30 in Germany

In line with Target 3 of the Kunming-Montreal Global Biodiversity Framework, the European Union (EU) aims to protect 30% of its land and sea by 2030 (known as 30x30). Germany has been a vocal supporter of this goal in the international arena but has yet to achieve sufficient protected area coverage domestically. We estimate that Germany needs to report an additional 4.65 million hectares of protected land to achieve 30x30. This article examines the potential of privately protected areas (PPAs) and other effective area-based conservation measures (OECMs) to contribute to this goal. We explore the German Federal Nature Conservation Act and identify the legal hurdles for the designation and recognition of PPAs. Furthermore, we argue that OECMs have the potential to contribute significantly to 30x30 in Germany. We estimate that close to one million hectares of land could be classified as OECMs and outline potentially qualifying sites. In conclusion, we discuss the prerequisites for upscaling private land conservation in Germany, focusing on required conditions for establishing OECMs and incentivising conservation easements and long-term conservation leases through national funding programmes.

Assessing the potential of Other Effective area-based Conservation Measures (OECMs) for contributing to conservation targets: A global scoping review protocol

This scoping review (ScR) protocol aims to establish the methodological approach for identifying and mapping the evidence regarding the actual contribution of Other Effective area-based Conservation Measures (OECMs) to spatial conservation targets. Emphasis will be placed on examining the research conducted, including the methodologies applied. OECMs, introduced by the Convention on Biological Diversity (CBD) in 2010, refer to areas outside of protected areas, such as fisheries restricted areas, archaeological sites, and military areas, that effectively conserve biodiversity in-situ over the long term. OECMs are recognized rather than designated. Many countries currently endeavor to identify, recognize and report OECMs to the CBD for formal acceptance to support the implementation of spatial conservation targets. Studies that assess the contribution of OECMs to spatial conservation targets will be considered. Potential OECMs with primary, secondary or ancillary conservation objectives established by all sectors in the terrestrial, freshwater and marine realm worldwide will be considered. Peer-reviewed and grey literature will be considered without imposing limitations based on publication year, stage, subject area and source type. Both experimental and observational studies in English, French, German, Greek, Italian, and Spanish will be reviewed. The ScR will follow the Joanna Briggs Institute (JBI) methodology. The protocol will be guided by the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) extension for scoping reviews. The search will encompass bibliographic databases such as Scopus, Web of Science and Google Scholar. Grey literature sources will include databases, pre-print archives and organizational websites. The Covidence platform will be utilized for data management and extraction.

Coverage and beyond: how can private governance support key elements of the Global Biodiversity Framework’s Target 3?

A vast cross-societal effort will be needed to achieve the ambition of protecting and conserving 30% of the earth’s lands and oceans by 2030, as called for in Target 3 of the Kunming-Montreal Global Biodiversity Framework. While focus is often given to the 30% coverage aspect of this target, other elements – on the location and effectiveness of protected and conserved areas – are equally important. As the implementation of Target 3 progresses, it is increasingly acknowledged that non-profit organisations, for-profit organisations, and individual landowners play a key role by choosing to manage their lands and waters to deliver conservation outcomes. However, privately protected and conserved areas lack recognition by many governments charged with reporting progress on the target. For countries and territories where these areas have been reported, we use the World Database on Protected Areas to explore their contribution towards elements of Target 3, particularly coverage, connectivity and ecological representation. In addition, we explore how privately governed ‘other effective area-based conservation measures’ contribute to Target 3 in countries and territories where they have been identified. Our results demonstrate that privately protected and conserved areas play a significant role in some countries’ efforts to meet Target 3. Since these areas are known to be under-reported, we stress the need for scaled up efforts for their recognition and documentation. This is vital not only for Target 3 tracking and implementation, but to ensure private actors receive appropriate recognition and support for their role in tackling the biodiversity and climate crises.

Developing a framework to improve global estimates of conservation area coverage

AbstractArea-based conservation is a widely used approach for maintaining biodiversity, and there are ongoing discussions over what is an appropriate global conservation area coverage target. To inform such debates, it is necessary to know the extent and ecological representativeness of the current conservation area network, but this is hampered by gaps in existing global datasets. In particular, although data on privately and community-governed protected areas and other effective area-based conservation measures are often available at the national level, it can take many years to incorporate these into official datasets. This suggests a complementary approach is needed based on selecting a sample of countries and using their national-scale datasets to produce more accurate metrics. However, every country added to the sample increases the costs of data collection, collation and analysis. To address this, here we present a data collection framework underpinned by a spatial prioritization algorithm, which identifies a minimum set of countries that are also representative of 10 factors that influence conservation area establishment and biodiversity patterns. We then illustrate this approach by identifying a representative set of sampling units that cover 10% of the terrestrial realm, which included areas in only 25 countries. In contrast, selecting 10% of the terrestrial realm at random included areas across a mean of 162 countries. These sampling units could be the focus of future data collation on different types of conservation area. Analysing these data could produce more rapid and accurate estimates of global conservation area coverage and ecological representativeness, complementing existing international reporting systems.

Marine spatial planning for connectivity and conservation through ecological corridors between marine protected areas and other effective area-based conservation measures

Maritime Spatial Planning (MSP) promotes the sustainable human activities development and uses in the marine space, playing a role in their effective management. The enhancement of connectivity is crucial for the conservation of biodiversity and landscape planning. Ecological Corridors (ECs) are an important type of connectivity for biodiversity conservation in fragmented habitats. The EU Biodiversity Strategy 2030 includes ECs into the network of protected areas and allows for the creation of additional protected areas. MSP studies considering ECs remain still lacking, especially for the design of networks between Marine Protected Areas (MPAs) and Other Effective area-based Conservation Measures (OECMs). In this paper, knowledge, and tools for investigating marine ECs were reviewed, with a systematic bibliometric analysis to summarize the current scientific research. Previous studies integrating ecological connectivity into planning for marine conservation have focused on models of larval dispersal, adult movements, and dispersal of single species by using benthic habitat proxies. Few studies were found on ECs in marine environments: in the coral Caribbean reef systems in the Gulf of Mexico; within benthic habitats along the Pacific coast of Canada; between MPAs in British Columbia (Canada); and by analyzing migratory species in the Yangtze estuary (China). Commonly used approaches to project and map ECs in marine environments are least-cost and circuit theories allowing to incorporate movement with cost or resistance to movement, depending on species and preferred habitats. The systematic bibliometric analysis returned 25 studies, most of which were from North America (40%) and European countries (36%) and the largest share of papers (68%) from 2018 to 2022. This review pinpointed the need of integrating different disciplines to investigate connectivity and the need by policymakers and practitioners to recognize the importance of ecological connectivity, even there are significant challenges for integrating connectivity into policies, planning, and conservation.

Mexico on Track to Protect 30% of Its Marine Area by 2030

Mexico has committed to protecting 30% of its marine territory by 2030 to comply with Target 3 of the Kunming–Montreal Global Biodiversity Framework, adopted during the 15th Conference of the Parties to the Convention on Biological Diversity. In this paper, we demonstrate the feasibility of meeting this commitment by determining the marine extent of conservation measures based on legally established Marine Protected Areas and areas that meet the criteria to be considered as Other Effective area-based Conservation Measures (OECMs) and determining the marine extent of areas proposed in various conservation planning exercises that can be created as any of the area-based instruments that exist in Mexico. The total coverage of existing and proposed areas was calculated by merging the dataset to remove duplicates and dissolving the boundaries between polygons to determine the total area. Spatial analysis was carried out in ArcGIS using geoprocessing tools. Currently, more than 25% of Mexico’s marine area is legally protected or conserved, with federal marine protected areas covering more than 22% of the Exclusive Economic Zone. The legally established areas that can be considered OECMs cover about 3% of the marine territory. We found that more than 9% of Mexico’s Economic Exclusive Zone contains areas of high conservation importance that are not covered by any area-based instrument. This study shows that Mexico has the potential to protect or conserve 32.8% of its marine territory by 2030.

A global assessment of forest integrity within Key Biodiversity Areas

Forest ecosystems cover one third of the terrestrial land surface, with those that are still functioning and largely intact being critically important for the conservation of threatened and endemic biodiversity. Key Biodiversity Areas (KBAs) are sites contributing significantly to the global persistence of biodiversity; >16,000 KBAs have been identified to date, almost half of which are of importance to forest species, including one-fifth that are important for one or more globally threatened species. It is important to track changes in forest integrity within KBAs to determine which important areas are under the greatest threat (so as to identify the actions needed), and also to track the overall effectiveness of conservation interventions. We utilised the Forest Landscape Integrity Index (FLII), which has been mapped globally at a 300 m resolution, to measure trends in forest integrity across 6844 KBAs of importance for forest biodiversity. In total 54 % (3.9 million km2) of these KBAs was forested, of which 44 % (1.7 million km2) is considered still to be of high integrity. South America, Africa and Asia were regions with the largest areas of high integrity forest within KBAs, while Oceania and Australasia had proportionally the highest amount of high forest integrity within their KBAs. We found that forest integrity was proportionally higher in larger KBAs, KBAs with larger proportions of forest, KBAs located close to other forested KBAs, and in protected KBAs. Unprotected and partially protected high-integrity forested KBA areas (making up 26 % of the current forested KBA estate) are among the highest priorities for assessing required conservation actions, including restoration to increase connectivity and reduce fragmentation and edge effects, and/or efforts to expand protected areas or other effective area-based conservation measures' (OECMs).

Canada and ocean climate adaptation: tracking law and policy responses, charting future directions

This research article provides a law and policy summary of climate change adaptation initiatives in Canada at the ocean-climate nexus. Three levels of governance are examined (national, provincial, and Indigenous) with a focus on the Atlantic region. The research method was the review of relevant and newly amended laws, regulations and policy statements, and related commentaries. The roles of the federal government are first described with key developments including the launch of a Climate Adaptation Platform in 2012 to share adaptation experiences and information and release of a National Adaptation Strategy and accompanying Adaptation Action Plan in November 2022. Federal adaptation efforts in the areas of fisheries, aquaculture and shipping are also reviewed along with progress in establishing marine protected areas (MPAs) and other effective area-based conservation measures. Provincial adaptation initiatives are next summarized with a focus on the four Atlantic provinces. Those provinces have established a regional hub, CLIMAtlantic, to provide climate information and advance climate-related research and training. Each province has developed a climate action plan which includes climate adaptation priorities. Indigenous-led climate engagement and adaptation initiatives are finally described including the publication in 2019 of a National Inuit Climate Change Strategy, regional initiatives of the Atlantic Policy Congress of First Nations Chiefs Secretariat, and the development of climate adaptation plans by select First Nation communities in the Atlantic region. The paper concludes by discussing future law and policy directions to make Canada more “climate ready.” Adoption of climate adaptation strategies for governmental departments and agencies with ocean and coastal responsibilities should be a priority. Incorporating climate change adaptation responsibilities through legislative and regulatory changes also needs to be considered, for example, by amending Canada’s Oceans Act to recognize the role of oceans in climate adaptations and mitigation, to authorize the designation of MPAs as climate refuges and to require adaptive and dynamic MPA management plans through strict monitoring and timely review provisions. Indigenous peoples must be effectively included in all climate adaptation discussions and planning.

Progress developing the concept of other effective area-based conservation measures.

In 2010, the introduction of other effective area-based conservation measures (OECMs) into international policy caused a paradigm shift in area-based conservation, which included consideration of areas outside formal protected areas and places where biodiversity conservation may not be a management objective for the site. Despite the importance of this shift for global conservation, conservation science and policy have been slow to engage with the concept of OECMs. As the world moves toward protecting 30% of the Earth by 2030, it is imperative to develop evidence-based guidance for how to identify effective conservation measures, especially tools to help evaluate and monitor the biodiversity outcomes associated with potential OECMs. To understand the current progress in developing the concept of OECMs, I evaluated the peer-reviewed literature to consolidate and synthesize current knowledge. I conducted a thematic analysis of papers to identify the types of challenges and opportunities being discussed and lessons from studies evaluating the effectiveness of OECMs. Only 105 studies mentioned OECMs, and those that did rarely move beyond superficial mention of OECMs as part of area-based conservation. Around one-half of studies listed potential risks or benefits of OECMs but none provided evidence these issues have materialized. Twenty-three studies attempted to identify potential OECMs, although specific case studies were rare. The 7 studies that evaluated existing OECMs were highly critical of how they had been implemented to date. Studies that evaluated conservation outcomes were extremely rare, and suggested effectiveness must be judged on a case-by-case basis. The current literature not only leaves many gaps in the science required to operationalize the concept of OECMs, but also often raises additional questions that need to be addressed. If these gaps are not filled by robust science, the promised benefits for biodiversity from OECMs may never be realized.

Positive effects of two decades of passive ecological restoration in a historically polluted marine site

The Mediterranean Sea is one of the most exploited regions of the world’s oceans. Here industrial activities have determined either acute or long-term impacts on coastal marine ecosystems. In this study, we investigated macrofauna distribution and diversity, and food-web functioning in a coastal area of the Mediterranean Sea facing an industrial chemical plant abandoned in the ‘90s to assess benthic ecosystem health. This area has been identified as a Site of National Interest (SNI) since 2002 and has been closed to any human activity awaiting to be remediated according to national laws. Our results indicate that, two decades after the SNI declaration (a decade after the plant decommissioning), there is no longer any sign of the impact of historical contaminations on macrofauna and benthic food web functioning. Overall, all the thirty-six sites showed high/good ecological quality according to the score assigned by AMBI and M-AMBI indexes, reflecting the absence of chronic impacts. Our findings reveal, for the first time, the positive effects of passive restoration (i.e., unassisted, or spontaneous recovery following cessation of anthropogenic impacts) on historically impacted coastal ecosystems since their health conditions, in terms of both abiotic (environmental variables and contaminant concentration) and biotic (macrofauna diversity and community composition, and benthic food-web structure) factors, were indistinguishable from surrounding non-impacted areas. These findings also suggest that other effective area-based conservation measures (OECMs) could be useful not only for biodiversity conservation of vulnerable and priority habitats in larger ocean sectors but also to promote the passive recovery of historically contaminated ecosystems.

Assessing the potential of Other Effective area-based Conservation Measures (OECMs) for contributing to conservation targets: A global scoping review protocol.

Other Effective Area-Based Conservation Measures, Biodiversity Stewardship and Statutory Intervention – A South African Perspective

Area-based approaches are a central component of global efforts to conserve biodiversity. While the focus of many countries has been mainly on protected areas, other effective area-based conservation measures (OECMS) have been accorded global recognition in the past decade as a vital complementary approach to protected areas. This recognition has been reemphasised in the Kunming-Montreal Global Biodiversity Framework adopted by parties to the Convention on Biological Diversity in December 2022, with its Target 3 ratchetting up area-based coverage targets to 30 per cent by 2030. A growing focus and reliance on OECMs to contribute towards achieving this target is anticipated. The international community has in the past few years introduced some guidance to identify, secure, manage, monitor and verify the anticipated long-term biodiversity conservation outcomes of OECMs. Some commentators have argued for domestic legal intervention to complement this general international guidance. The South African Government has recognised the potential contribution of OECMs towards the achievement of domestic and global area-based biodiversity targets in its National Protected Areas Expansion Strategy (2018) but has alluded to the need for legal intervention to ensure that they achieve positive and sustained long-term outcomes for the in situ conservation of biodiversity. Some domestic commentators have highlighted the strong link between biodiversity stewardship (particularly conservation areas) and OECMs, advocating that these conservation areas should form the priority focus of domestic efforts to identify OECMs. This article scopes this potential link and specifically considers whether the current domestic legal and policy framework applicable to these conservation areas is sufficiently robust to ensure that only appropriate areas are identified as OECMs and that once recognised, they are governed and effectively managed in the long term. It highlights several frailties of the existing framework and drawing from anticipated legal reform in the Western Cape relating to biodiversity stewardship, it proposes a possible model for future national legislation regulating OECMs.

Assessing the effectiveness of potential protected areas and OECMs in conserving biodiversity against subsurface resource extraction impacts

The direct and indirect impacts of resource extraction activities are an increasingly important planning and management challenge for organizations responsible for protected areas and other effective area-based conservation measures (OECMs). The development of subsurface resources in protected areas or OECMs can have significant implications for the ways in which such areas are established and their overall effectiveness in conserving biodiversity. In this article, we introduce a decision-support tool, developed through expert consensus and real-world application, that can be used to assist organizations to evaluate the effectiveness of conservation mechanisms (laws, regulations, and associated policies) and other management tools from potential subsurface resource extraction activities. The tool provides a novel and comprehensive method to determine whether a potential protected area or OECM is effective in managing all subsurface activities that may have an impact on biodiversity. While developed in Canada, the tool has universal applicability for conservation managers globally working to achieve standards of protection for biodiversity. We conclude by discussing the ways in which Parties to the Convention on Biological Diversity (CBD) can consider resource extraction rights and impacts in national efforts to effectively achieve the goals and targets of the recently adopted Kunming-Montreal Global Biodiversity Framework (GBF).

A Conceptual Framework for Biodiversity Monitoring Programs in Conservation Areas

Maintaining and improving the state of biodiversity is a primary factor guiding management activities in conservation areas, including protected areas (PAs) and other effective area-based conservation measures (OECMs). Due to the complex nature of conservation programs, a common management approach cannot be prescribed. Robust monitoring programs supporting management activities are required to evaluate the state of species and habitats. However, limited resources, poor data management practices, and competing requirements of stakeholder groups increase the challenges that must be addressed through realization of monitoring programs. We propose a framework of seven basic questions to guide conservation area managers to implement effective biodiversity monitoring techniques. The result is identification of indicators, site characteristics, and resources to promote the development of a biodiversity monitoring program. We call for adoption of a strategic guideline providing this framework to harmonize decision making processes across national and international networks. Implementation of this robust framework will support comparative monitoring data, contributing to systematic approaches for adaptive management in PAs and OECMs and improving the body of knowledge surrounding global biodiversity.

Saving two fish with one wreck: Maximizing synergies in marine biodiversity conservation and underwater cultural heritage protection

The oceans harbor critical areas of marine biodiversity and underwater cultural heritage, both of which require active protection and preservation for the future. Here, we consider how the presence of underwater cultural heritage can be used to bolster the conservation of marine biodiversity, and vice versa. We perform spatial analyses showcasing where sea-space of high cultural and natural value overlaps. Subsequently, we identify three potential synergies that could lead to better outcomes for underwater cultural heritage and marine biodiversity: (1) overlap in the definitions of world heritage, Marine Protected Areas (MPAs), and other effective area-based conservation measures (OECMs); (2) synergies between shipwreck management and fisheries management; and (3) synergies around sustainable tourism and livelihoods. We then contextualize our argument using a case study in Indonesia involving the governance of the HMAS Perth (I) wreck and its Maritime Conservation Zone. Our discussions are relevant to marine managers and policy makers, as well as practitioners involved in economic activities that benefit from, and can impact, marine biodiversity and underwater cultural heritage, such as fishing and dive tourism.
