Capacity shortfalls hinder the performance of marine protected areas globally

Marine protected areas (MPAs) are increasingly being used globally to conserve marine resources. However, whether many MPAs are being effectively and equitably managed, and how MPA management influences substantive outcomes remain unknown. We developed a global database of management and fish population data (433 and 218 MPAs, respectively) to assess: MPA management processes; the effects of MPAs on fish populations; and relationships between management processes and ecological effects. Here we report that many MPAs failed to meet thresholds for effective and equitable management processes, with widespread shortfalls in staff and financial resources. Although 71% of MPAs positively influenced fish populations, these conservation impacts were highly variable. Staff and budget capacity were the strongest predictors of conservation impact: MPAs with adequate staff capacity had ecological effects 2.9 times greater than MPAs with inadequate capacity. Thus, continued global expansion of MPAs without adequate investment in human and financial capacity is likely to lead to sub-optimal conservation outcomes

Equitable and effective area‐based conservation: towards the conserved areas paradigm

In 2018, the Parties to the Convention on Biological Diversity (CBD) adopted a decision on protected areas and other effective area-based conservation measures (OECMs). It contains the definition of an OECM and related scientific and technical advice that has broadened the scope of governance authorities and areas that can be engaged and recognised in global conservation efforts. The voluntary guidance on OECMs and protected areas, also included in the decision, promotes the use of diverse, effective and equitable governance models, the integration of protected areas and OECMs into wider landscapes and seascapes, and mainstreaming of biodiversity conservation across sectors. Taken as a whole, the advice and voluntary guidance provides further clarity about the CBD Parties’ understanding of what constitutes equitable and effective area-based conservation measures within and beyond protected areas and provides standardised criteria with which to measure and report areas’ attributes and performance. This policy perspective suggests that this CBD decision represents further evidence of the evolution from the ‘new paradigm for protected areas’ to a broader ‘conserved areas paradigm’ that embodies good governance, equity and effective conservation outcomes and is inclusive of a diversity of contributions to conservation within and beyond protected areas

Evolution of microhabitat association and morphology in a diverse group of cryptobenthic coral reef fishes (Teleostei: Gobiidae: Eviota)

Gobies (Teleostei: Gobiidae) are an extremely diverse and widely distributed group and are the second most species rich family of vertebrates. Ecological drivers are key to the evolutionary success of the Gobiidae. However, ecological and phylogenetic data are lacking for many diverse genera of gobies. Our study investigated the evolution of microhabitat association across the phylogeny of 18 species of dwarfgobies (genus Eviota), an abundant and diverse group of coral reef fishes. In addition, we also explore the evolution of pectoral fin-ray branching and sensory head pores to determine the relationship between morphological evolution and microhabitat shifts. Our results demonstrate that Eviota species switched multiple times from a facultative hard-coral association to inhabiting rubble or mixed sand/rubble habitat. We found no obvious relationship between microhabitat shifts and changes in pectoral fin-ray branching or reduction in sensory pores, with the latter character being highly homoplasious throughout the genus. The relative flexibility in coral-association in Eviota combined with the ability to move into non-coral habitats suggests a genetic capacity for ecological release in contrast to the strict obligate coral-dwelling relationship commonly observed in closely related coral gobies, thus promoting co-existence through fine scale niche partitioning. The variation in microhabitat association may facilitate opportunistic ecological speciation, and species persistence in the face of environmental change. This increased speciation opportunity, in concert with a high resilience to extinction, may explain the exceptionally high diversity seen in Eviota compared to related genera in the family. © 2012 Elsevier Inc

Quantifying the Reporting, Coverage and Consistency of Key Indicators in Mangrove Restoration Projects

Mangroves are often cleared for aquaculture, agriculture, and coastal development despite the range of benefits for people and nature that they provide. In response to these losses, there are multiple global, and regional efforts aimed at accelerating mangrove forest restoration, resulting in many restoration projects being implemented and managed by different groups with highly diverse objectives. The information reported from these restoration projects is extremely variable, limiting our ability to identify whether desired objectives have been met or key factors that determine effective and durable restoration have been applied. To address this problem, we developed a holistic monitoring framework that captures the key indicators of restoration, spanning project aims, intervention type, costs, and ecological and socioeconomic outcomes. Subsequently, using a systematic literature search, we examined 123 published case studies to identify the range and quality of reported information on restoration, relative to our framework. We found that there were many gaps in reporting, for multiple indicators. Sections related to site conditions prior to restoration (reported in only 32% of case studies) and socioeconomic outcomes (26%) were consistently missing from most project reporting. Conversely, information on the type of intervention was reported for all case studies, and the aims of the project (reported in 76% of case studies) and ecological monitoring (82%) were far more prevalent. Generally, the restoration literature did not follow any specific framework in terms of reporting which likely contributed to the gaps in the information recorded. These gaps hinder comparisons between case studies, inhibiting the ability to learn lessons from previous restoration attempts by identifying commonalities. The need for more structure and consistent reporting supports the development of a standard restoration tracking tool that can facilitate the comparison of restoration efforts, aiding the implementation of future projects.</jats:p

The rapid expansion of Indonesia’s marine protected area requires improvement in management effectiveness

Indonesia’s marine ecosystems are among the most diverse in the world, supporting extensive critical habitats with strong connections to coastal communities. To keep pace with increasing pressures on the environment, conservation efforts need to be strengthened and expanded. The Government of Indonesia has committed to protecting marine ecosystems through establishing 32.5 million ha of marine protected areas (MPAs), with 20 million ha effectively managed, by 2030. Therefore, collating data on the status and progress of marine conservation efforts nationally is important to show the extent to which this target is being reached. Here we provide an overview of the status and trends of spatial coverage and management effectiveness of MPAs in Indonesia. As of 2020, Indonesia had made good progress in reaching its target – with 23.9 million ha MPA established and some —albeit slow— increases in MPA management effectiveness. Moving forward, we recommend that marine protection efforts in Indonesia need to balance MPAs expansion with improvement in effectiveness. Improvement of management effectiveness will require significant efforts, including improving institutional coordination, ensuring adequate human and financial resources, and strengthened monitoring, evaluation, and learning to inform adaptive management. Future MPA expansion should focus on addressing specific gaps in the existing network, such as increasing coastal habitat representation, and connectivity, or increasing recognition of a diversity of governance approaches (e.g., by communities or private entities). Progress over recent decades, however, suggests Indonesia is making progress on its marine protection goals and is well placed to meet potential future targets

The inclusion of fisheries and tourism in marine protected areas to support conservation in Indonesia

With the rapid growth of Indonesia’s marine protected area (MPAs) estate in Indonesia, reaching 23.9 million hectares by January 2020, attention needs to be focused on strengthening the effectiveness of MPA management. Consolidating and expanding protection of Indonesia’s marine resources is critical with increasing pressure from a fast-expanding population, illegal, unreported, and unregulated fishing, pollution, coastal development, unsustainable tourism and climate change. Biodiversity conservation must therefore concurrently consider multiple economic sectors such as fisheries and tourism, and their synergies with MPA management. This paper aims to outline the current landscape of fisheries and marine tourism pertaining to area-based conservation in Indonesia, to inform and support improved integration into effective MPA management. Four areas to focus efforts were identified: diversification of governance types of community-based management, improved coordination between fisheries and MPAs during planning and management implementation, the development and support of pathways for sustainable tourism, and planning for future conditions. Sustainable development for fisheries and tourism must be incorporated into all aspects of MPA management, whilst recognising that current management systems are insufficient to ensure long-term sustainability for natural resources and local communities, and strategies need to increase resilience of social-ecological systems in anticipation of future conditions
