Uncovering data gaps in biodiversity research within Brazilian Atlantic Forest restoration

Bringing together and synthesizing data from several primary studies and scales represents a powerful method for identifying patterns and gaps within forest restoration science. In this study, we employ a pioneer quantitative database‐driven review combined with spatial analysis to delineate research trends across biodiversity studies within the Brazilian Atlantic Forest (BAF). We gathered a total of 90 primary studies that met our inclusion criteria, collectively providing 822 observations (comparisons between restoration sites and reference forests) spanning restoration areas with ages ranging from 1 to 90 years old. Vascular plants and invertebrates dominated in terms of data availability, whereas soil microorganisms were the subject of limited inquiry. There is an evident disparity in the number of evidences for different forest types across regions, with mixed forest being underrepresented in relation to seasonal forest and dense forest (rainforest). On the contrary, we observed an even distribution of biodiversity outcomes across the age categories we defined for reference forests (i.e. secondary forest, secondary advanced, and old‐growth forest). Geospatial analysis revealed a concentration of research efforts within the southeastern region of the BAF. However, a significant research deficit remains for the northeast and south regions, crucial for comprehending biodiversity responses to restoration in environmental extremes. By integrating both qualitative and quantitative approaches, this framework review provides a roadmap for deepening our understanding of biodiversity responses to restoration in the BAF. Ultimately, it serves as a bridge between quantitative findings and nuanced contextual insights, guiding future research and similar studies across diverse ecosystems worldwide.

Transformation in the forest: the role for restoration in the transition away from native forestry in Australia

The native forestry industry is being reconsidered, or actively phased out, across most parts of Australia. This kind of transition has happened elsewhere in the world but, in Australia, there is no clarity from governments about what those forestry areas will become, from an ecological or legal perspective. In this research, we investigate the ecological, climatic, and governance contexts for this transition away from native forestry, placing our results in the context of the Global Biodiversity Framework's push to restore 30% of the Earth's land, coasts and oceans. We demonstrate important gaps in government planning for the future of former native forestry coupes, arguing that “after forestry” many of these places will need active intervention to recover these ecosystems and address historic land degradation. This case study combines legal analysis with a review of the restoration literature to illustrate the importance of the governance framework within which restoration science is evolving. We demonstrate the complexity of governing restoration at large scales as the climate changes, as well as potential opportunities to reconcile fragmented governance arrangements, to ensure that this transition results in resilient forest ecosystems in currently degraded areas.

Ten golden rules for restoration to secure resilient and just seagrass social‐ecological systems

Societal Impact StatementSeagrass meadows are a globally important habitat subject to significant loss. As efforts to restore these sensitive habitats are hampered by their high cost and low levels of reliability, rigorous guidance is required to improve effectiveness and ensure they are cost‐effective. Here, we define 10 golden rules for how we can undertake seagrass restoration. We do this by considering that for seagrass restoration to be successful, it needs to take place with people and not against people. The framework we present aims to direct efforts for seagrass restoration that are holistic and achieve broad goals for people, biodiversity and the planet.SummaryThe world has lost a significant proportion of its seagrass, and although glimmers of hope for its recovery exist, losses and degradations continue. First and foremost, evidence highlights the need to put the world on a global pathway to seagrass net gain. Achieving this outcome requires that conservation of what remains is a priority, but reaching net gain requires seagrass coverage to increase at rates unlikely to be achieved naturally; large‐scale active restoration is required to fill this gap. Novel finance mechanisms aligned to the climate emergency and biodiversity crises are increasingly leading to larger scale restoration projects. However, no clear framework exists for developing or prioritising approaches. With seagrass restoration expensive and unreliable, rigorous guidance is required to improve effectiveness and ensure it is cost‐effective. Building on evidence from terrestrial and marine sources, here, we apply the ‘10 golden rules’ concept, first outlined for reforestation and later applied to coral reefs, to seagrass restoration. In doing so, we follow international standards for ecological restoration and view seagrass restoration in a broad context, whereby regeneration can be achieved either by planting or by enhancing and facilitating natural recovery. These rules somewhat differ from those on reforestation and coral reef restoration, principally due to the relative immaturity of seagrass restoration science. These 10 golden rules for seagrass restoration are placed within a coupled social‐ecological systems context, and we present a framework for conservation more broadly, to achieve multiple goals pertaining to people, biodiversity and the planet.

An introduction to key ecological concepts, financial opportunities, and risks underpinning aspirations for nature positive.

Global biodiversity is in decline, and businesses and society are being required to urgently create new operating models to ameliorate the crisis. Among the strategies proposed to do this, implementing the concept of nature positive has captured worldwide attention. Critical to its success will be effective collaboration between ecologists and businesspeople, driven by a shared understanding of key nature positive terminology, concepts, and risks. To this end, we introduce three core aspects: the ecological concepts in the definition of nature positive (health, abundance, diversity, and resilience), a typology of financial instruments that may be applied to achieving nature positive, and an overview of risks to biodiversity and society. The pivotal findings include that ecological complexity and uncertainty belie the simplicity of the definition of nature positive and that managing risk requires embedding aspirations into existing and emerging biodiversity conservation and restoration science and policy. Although it is challenging, nature positive deserves pursuit.

The Benefits of Informal Learning Garnered Through Participation in the Curriculum and Community Environmental Restoration Science (STEM + Computer Science) Project

The Curriculum and Community Environmental Restoration Science (STEM + Computer Science) Project has several goals, with its primary focus on connecting the students of New York City with the enormous potential of restoring New York Harbor to its former self. Through the collaboration of numerous partners representing all of the facets of the city to the marginalized students living in hundreds of under-resourced communities, out-of-school experiences such as participation in the annual Science Symposium and the environmental fieldwork conducted along the shores of New York Harbor flourished. The CCERS STEM + C Project enables the merging of these entities for the good of its participants and the enormous benefit to the environment's restoration. This study consists of student surveys administered to and completed by 513 students attending schools throughout New York City's five boroughs. Of those who responded to the ethnicity section of the survey, 43.7% represent minority students. Data indicated a significant increase in STEM motivation by the CCERS STEM + C participating students, particularly those who identify as members of the under-represented minority group.

The Billion Oyster Project and Curriculum and Community Enterprise for Restoration Science Curriculum: Summary of STEM+C and ITEST Program Impacts on NYC Teachers and Students

For over a decade, the Billion Oyster Project and Curriculum and Community Enterprise for the Restoration of New York Harbor (BOP-CCERS) Educational Program has supported New York City teachers and students through experiential learning in science education. The program has been supported by over $10 million dollars of award support from the National Science Foundation (NSF) and has involved multiple community stakeholder collaborations led by Pace University. Within the University, the initiative spanned three different schools and colleges with collaboration through many academic departments. Two grants in the project have been the Science, Technology, Engineering, and Mathematics plus Computing (STEM+C) and Innovative Technology Experiences for Students and Teachers (ITEST) program. The purpose of this article is to summarize the major impacts this integrated program has had on New York City teachers and students designed to provide teachers with experiential education support and engage students to improve their STEM education and encourage further STEM studies and career pathways. Results from over a decade of programming, vast amounts of data collection and analysis, and multiple research studies have indicated considerable achievements for the program involving both support for teachers and engagement for students. The long-term outcome is improved student STEM achievement and recruitment and retention of diverse students in STEM college programs and careers.

Global trends in applying decision science in mangrove restoration: are we missing some dimensions?

Mangrove restoration involves complex decision-making processes and can often lack adequate stakeholder engagement and empowerment to inform effective restoration outcomes. Decision science has the potential to overcome such challenges by facilitating structured approaches to make informed, participatory, and defensible decisions through the use of decision-support frameworks and tools. In this paper, we conduct a bibliometric and scoping review of peer-reviewed scientific literature to identify how decision science has been applied to advise mangrove restoration efforts and the extent to which social, economic, and ecological variables have been used to inform these studies. We find a steady increase in the number of mangrove restoration studies that employ decision science from 1990 to 2022, with an annual growth rate of 4.4%. We identified over 300 decision support tools used in mangrove restoration literature. Spatial data was the most documented tool to support mangrove studies. We also find that most papers focused on ecological variables (85.5%), while social (27.2%) and economic (15.1%) variables received less attention. Studies that used decision support frameworks were also sparse, where the most featured framework was Systematic Conservation Planning. The number of studies explicitly incorporating social and economic variables was limited, and there was also a scarcity of studies incorporating variables associated with governance. Regardless of the dominance of ecological variables, this review highlights a shift towards incorporating social dimensions into decision tools, emphasizing concepts like vulnerability to climate change, ecosystem services, and social benefits. Collaboration among countries, scientists, and practitioners is crucial to operationalise a socio-ecological framework within decision science. Enhancing the utility of scientific research for practitioners remains a critical goal in addressing the challenges faced by mangrove restoration projects globally.

The Curriculum and Community Environmental Restoration Science (STEM + Computer Science) Project – Attaining a STEM Mindset Through Improved Technological Ability

Increasing students’ confidence in their technological ability has been found to have a broader impact on their content knowledge in several subject areas, but most strikingly, in STEM (science, technology, engineering, and mathematics). A sample of 513 students in grades 6 through 12 in the New York City public school system were questioned on their perceived technological ability after participating in The Curriculum and Community Environmental Restoration Science (STEM + Computer Science) Project, hereafter referred to as the CCERS STEM + C Project. Also explored was the students’ access to technology to determine if this would be a factor in student self-efficacy in technology ability. Analysis revealed that science self-efficacy and technology ability were both strengthened through participation in the project. Additionally, the study found that working alongside STEM professionals and exposure to STEM careers were also contributing factors. The study aims to determine if increased access to technology would, in turn, increase students’ self-efficacy in their technology knowledge and skills and have a positive effect on their self-confidence in STEM content. The results of the study contribute to the body of research that suggests greater access to technology may be an important factor in students’ self-agency and academic achievement.

Students’ Self-Efficacy and Confidence in Technological Abilities Resulting from Participation in “The Curriculum and Community Environmental Restoration Science (STEM + Computer Science)”

The rationale for this research is the ever-increasing reliance on technology in all aspects of life, but especially in the realm of education. Technology tools, use, and approaches that support inclusive student learning are supported by the empirical evidence found in this report. The research emphasized self-efficacy levels achieved in the student learning of technology-supported integrated science, technology, engineering, and mathematics (STEM). The Curriculum and Community Environmental Restoration Science STEM + Computer Science (CCERS) makes use of web-based authentic STEM content, providing interactive technology on a dynamic environmental science platform and providing real-world environmental conundrums. Results of this study indicate that CCERS respondents have higher confidence in their technological abilities than those of the non-CCERS respondents. In addition, under-represented groups (URG) CCERS respondents, on average, have higher confidence in their technological abilities than URG non-CCERS respondents. This suggests that CCERS has a positive impact on participants' confidence in their technological abilities, a key indicator in pursuing STEM careers. This study provides practical implications for current and future research in technology-supported learning in integrated STEM learning environments and student outcomes.

Public preference for the rewilding framework: A choice experiment in the Oder Delta

Abstract Rewilding is an emerging paradigm in restoration science and is increasingly gaining popularity as a cost‐effective ecosystem restoration option. A rewilding framework was recently proposed that contains three integral components: restoring trophic complexity, allowing for stochastic disturbances and enhancing species' potential to disperse. However, as of yet, there has been limited quantitative analysis looking at public preference for rewilding and each of its elements. We used a discrete choice experiment approach to determine public preference for rewilding in the Oder Delta. The unique geographical context of the Oder Delta, spreading evenly across two countries, allowed us to analyse differences between the German (n = 1005) and Polish (n = 1066) samples. In both countries, we found that respondents were willing to pay for rewilding interventions when compared against a status quo option. Notably, preferences were strongest for restoring trophic complexity through promoting the comeback of large mammals. In addition, we found respondents living locally to the study region had significantly different preferences than the nationwide samples, exhibiting negative willingness to pay for the restoration of natural flooding regimes and the presence of large predator species.

“Out, Damned Spot”: The art and science of forensic restoration

Forensic restoration focuses on remediation of indoor environments that are contaminated with potentially hazardous biological materials. Some of the more challenging cases are those where someone has died alone and remained undiscovered for some time. Decomposition begins almost immediately after death: blood stops circulating and starts to pool and coagulate, and cells undergo autolysis. Our commensal microbes, critical to health during life, turn against us after death and start consuming us from within. Anaerobic microbial processes produce odorous volatile organic compounds and fluids that seep into the floor. Insects can oviposit in the body, resulting in masses of larvae feeding on the body. When ready to pupate, larvae leave, acting as vectors which can spread contamination around the site. Remediating a home where an unattended death has occurred involves removal of fluid-soaked items and a load reduction to remove soil, followed by a thorough cleaning to remove organic materials and prepare surfaces for disinfection, all while keeping operators safe from potential infectious agents. It’s certainly not a job for everyone, but one couple is trying to bring a higher level of science-based practices and training to the industry.

Historical trajectory of restoration practice and science across the Brazilian Atlantic Forest

Restoration is fundamentally a hopeful intervention that can meaningfully improve the condition of human‐degraded and destroyed ecosystems. Both restoration science and practice have gained special attention given the recently declared UN Decade of Ecosystem Restoration. Here, we present an overview of the historical development of forest restoration on the Brazilian Atlantic Forest with an emphasis in methodological and technical assumptions. We gathered information from primary and secondary studies to show how forest restoration concepts and strategies evolved over the years. Given the importance of reviews for informing management and policy as well as research, our study provides a summarized information on forest restoration approaches or practices that can help practitioners and non‐initiated to understand how this field evolved in Brazil and how lessons learned can be useful for forest restoration in other countries.

Convergence and divergence in science and practice of urban and rural forest restoration.

Forest restoration has never been higher on policymakers' agendas. Complex and multi-dimensional arrangements across the urban-rural continuum challenge restorationists and require integrative approaches to strengthen environmental protection and increase restoration outcomes. It remains unclear if urban and rural forest restoration are moving towards or away from each other in practice and research, and whether comparing research outcomes can help stakeholders to gain a clearer understanding of the interconnectedness between the two fields. This study aims to identify the challenges and opportunities for enhancing forest restoration in both urban and rural systems by reviewing the scientific evidence, engaging with key stakeholders and using an urban-rural forest restoration framework. Using the Society for Ecological Restoration's International Principles as discussion topics, we highlight aspects of convergence and divergence between the two fields to broaden our understanding of forest restoration and promote integrative management approaches to address future forest conditions. Our findings reveal that urban and rural forest restoration have convergent and divergent aspects. We emphasise the importance of tailoring goals and objectives to specific contexts and the need to design different institutions and incentives based on the social and ecological needs and goals of stakeholders in different regions. Additionally, we discuss the challenges of achieving high levels of ecological restoration and the need to go beyond traditional ecology to plan, implement, monitor, and adaptively manage restored forests. We suggest that rivers and watersheds could serve as a common ground linking rural and urban landscapes and that forest restoration could interact with other environmental protection measures. We note the potential for expanding the creative vision associated with increasing tree-containing environments in cities to generate more diverse and resilient forest restoration outcomes in rural settings. This study underscores the value of integrative management approaches in addressing future forest conditions across the urban-rural continuum. Our framework provides valuable insights for policymakers, researchers, and decision-makers to advance the field of forest restoration and address the challenges of restoration across the urban-rural continuum. The rural-urban interface serves as a convergence point for forest restoration, and both urban and rural fields can benefit from each other's expertise.

Characteristics and gaps in the assessment of progress in mine restoration: insights from five decades of published literature relating to native ecosystem restoration after mining

Desires that mine sites are restored to self‐sustaining native ecosystems providing benefits for people have been longstanding. However, achieving and demonstrating progress toward mine restoration goals is complex and requires sustained assessment of numerous disparate components. The recently released Society for Ecological Restoration Mine Site Restoration Standards (SER MSRS) recommend utilizing restoration science assessments to determine whether sites are developing toward similarity with targeted ecosystems and exhibiting self‐sustainability. We conducted a global review of publications that assessed restoration to native ecosystems after mining. Our objectives were to (1) document case studies of long‐term assessments of mine restoration and (2) evaluate the extent to which restoration assessment has reported the achievement of varied mine restoration goals on a global scale, including (3) whether any ecosystem components and restoration attributes are underrepresented in published assessments. Among the 712 publications we collated, we documented case studies with sustained reporting on similar restoration and significant increase over time in the quantity and breadth of attributes and ecosystems assessed. Nevertheless, notable gaps remain, or underreporting persists. For example, there have been relatively few assessments targeting understanding of key ecosystem processes, resilience, and threats to ecosystem persistence that are necessary for demonstrating “self‐sustainability.” Our review also revealed limited consideration of ecosystem services that rarely involved impacted communities. We recommend efforts to collate and expand assessments of similar restoration trajectories, placing more focus on indicators that enable the evaluation of characteristics and progress toward a self‐sustaining socioecological ecosystem, to help achieve the goals of mine site restoration.

Grassland restoration with plant material transfer – bridging the knowledge gap between science and practice

In Central Europe, species-rich grasslands have strongly diminished over the last century. The transfer of seed-containing plant material from donor sites with a desired species composition to restoration sites is a well-established method to restore species-rich grasslands. Despite a plethora of available literature, restoration projects with plant material transfer often fail or do not reach the planned goals. Practitioners’ knowledge is a highly important but underexplored source of information on factors deciding about success of restoration projects. At the same time, it is unclear to which degree scientific findings on success factors are known and considered by practitioners, and if science actually investigates the most relevant aspects for practice. To bridge the gap between practitioners’ knowledge and restoration science, we conducted semi-structured interviews with 33 practitioners involved in plant material transfer projects. Using qualitative content analysis, we analysed the interviews for success factors, and compared them to success factors of plant material transfer as investigated in peer-reviewed European studies on the method. We found that science investigated a broad range of practical, technical, and ecological success factors, and that practitioners were generally well aware of this evidence, trying to make use of the knowledge. Failure of practitioners’ projects often resulted from organizational obstacles, which were founded in lacking trust and low experience levels among the involved people. We advise unexperienced practitioners to involve more experienced practitioners in their projects if possible. Furthermore, we emphasize the importance of identifying relevant local stakeholders and building trustful regional networks. Interdisciplinary scientific studies considering success factors beyond practical and ecological aspects are required to support widespread effective grassland restoration with plant material transfer.

The Billion Oyster Project and Curriculum and Community Enterprise for Restoration Science Curriculum: ITEST Program Impacts on NYC School Student Scientific Identity

The Billion Oyster Project and Curriculum and Community Enterprise for the Restoration of New York Harbor with New York City Public Schools (BOP-CCERS) program is a National Science Foundation (NSF) supported initiative that involves multiple stakeholder collaborations and is led by Pace University. Within Pace, the initiative crosses over three different schools and colleges and across multiple departments. Pace University’s NSF project of focus in this article is the Innovative Technology Experiences for Students and Teachers (ITEST) program. The purpose is to increase student motivation and preparation for pursuing STEM careers. This article presents results of programming to increase student scientific identity. Findings revealed that students in the 11th grade had the highest level of scientific identity compared to other high school grades. These findings indicate that 11th grade may be an ideal timeframe for interventions to improve scientific identity. Moreover, project participants had higher levels of engagement in STEM-related activities, were more likely to watch videos made by scientists, and read articles written by scientists than those in the control group.

Recognising Indigenous plant-use histories for inclusive biocultural restoration

Indigenous Peoples have manipulated environments and species for millennia. However, restoration science often overlooks ancient human plant dispersal, niche construction, and selection pressures that may have resulted in plant ‘cultural traits’. Concerted efforts to acknowledge Indigenous plant-use histories in restoration could help to abate the coextinction of species and cultures.

Characterizing canopy complexity of natural and restored intertidal oyster reefs (Crassostrea virginica) with a novel laser‐scanning method

The structural complexity of oyster reef canopy plays a major role in promoting biodiversity, balancing the sediment budget, and modulating hydrodynamics in estuarine systems. Although oyster canopy structure is both spatially and temporally heterogeneous, oyster canopies are generally characterized using simple first‐order quantities, like oyster density, which may lack the ability to sufficiently parameterize reef roughness. In this study, a novel laser‐scan approach was used to map the surface of intact reference and restored reefs (restoration age: 1–4 years) during low tide, when the oyster canopy was fully exposed. Measurements were used to estimate hydrodynamically relevant roughness characteristics over the entire reef surface (>140 m2; 0.50 m resolution), providing estimates of the canopy height (hc), standard deviation (), rugosity index (R), and fractal dimension (D). Average canopy heights ranged from 3.6 to 4.9 cm, with canopy height standard deviations between 1.4 and 2.0 cm. Mean rugosity indices and fractal dimensions were relatively low on the youngest (1 year) restored reef (R = 1.28;D = 2.67), with substantial increases observed for more mature reef canopies (4 years:R = 1.56;D = 2.71). Structural complexity was consistently greater on reef margins than in reef interiors. Increases in complexity were linked to restoration age, with older reefs exhibiting more complex oyster canopies. The highest fractal dimension was observed on the intact reference reef, highlighting the importance of sustained reef growth for maintaining higher‐order structural complexity. Results provide spatially explicit surface roughness characterizations for healthy, intertidal oyster reefs, with applications in both restoration science and natural and nature‐based feature design.
