Problem-framing involves defining and delineating a problem to suggest practical and measurable solutions for addressing it. We are examining how the conservation conflict changes over time in Lac Saint-Pierre (LSP), part of the St. Lawrence River Basin in Québec, Canada. Such conflicts arise when there are differing perspectives, interests, or actions regarding conservation goals and objectives. In recent decades, the LSP floodplain has undergone significant changes, particularly the conversion of perennial crops to intensive annual crops, which are deemed incompatible with the ecological needs of yellow perch. This species has experienced a notable decline in LSP since the 1990s, prompting Québec authorities to impose a moratorium on yellow perch fishing in 2012 to safeguard stocks. This moratorium has catalyzed efforts at the policy level to restore its habitat. However, it has also engendered tensions between agricultural activities and conservation endeavors aimed at restoring yellow perch habitat, constituting the conservation conflict under investigation. To investigate this issue, we adopt a post-normal science approach characterized by reflexivity, inclusivity, and transparency in addressing epistemological and ontological uncertainties among LSP stakeholders. Our findings offer insights into stakeholders' perspectives on the problem-framing process and its outcomes, highlighting both supportive actions enhancing the effectiveness of certain strategies among LSP stakeholders and barriers hindering their mobilization. These results underscore the importance of incorporating diverse stakeholder perspectives during the problem-framing process to enhance the robustness of the science–policy interface.</p>","PeriodicalId":51337,"journal":{"name":"Conservation Science and Practice","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2024-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/csp2.13163","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142429110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using São Tomé and Príncipe as a case study, we illustrate how MSP was employed as an operational framework for establishing an MPA network. Drawing on the experiences of people directly involved in this co-design process, we reflect on the main challenges and opportunities in achieving social–ecological integration, and highlight recommendations for conservation practitioners and planners. Applying MSP was perceived to contribute substantially to multiple project goals, with some (e.g., incorporating perspectives and needs of vulnerable groups) more challenging to achieve. While MSP enhanced conceptual, disciplinary, methodological and functional integration, practical challenges in implementation hindered the extent to which each of these was achieved.

We interviewed 34 technical assistance staff supporting biodiversity programming at USAID to explore how technical assistance is used to support evidence use and the extent to which technical assistance can fulfill the functions of “evidence bridges”—intermediaries who help practitioners access and use bodies of evidence for decision-making. We found that the current technical assistance model supporting evidence employs varied strategies to support evidence use, some of which are more closely aligned with the functions of evidence bridges than others. We conclude that the current technical assistance model could strengthen support for evidence use through engagement with evidence bridges to promote uptake of synthesized evidence.

While state-managed protected areas remain key instruments for forest conservation, private actors are increasingly funding and implementing a broad range of conservation initiatives. Private actors are transforming the Amazonian conservation landscape and its governance, however, many aspects of private conservation, especially the diversity of local practitioners and the challenges they face, remain understudied. Drawing on a case study of Madre de Dios in the Peruvian Amazon, we aim to generate a better understanding of private conservation practitioners and their various approaches to conservation on private and public land. We used an extensive review of literature and databases, in addition to 13 semi-structured interviews with various private conservation practitioners, to map privately conserved areas, and to gather perceptions about challenges, opportunities, and future pathways for private conservation. A total of 590 privately conserved areas, covering over one million hectares, were identified and mapped in Madre de Dios. We find that, while most initiatives are managed by individuals and families, for-profit companies manage half of the total area privately protected. Furthermore, we find that private conservation initiatives face significant barriers and pressures. These barriers include complex bureaucratic processes, legal contradictions and incoherencies, corruption, weak law enforcement, and financial insecurity. Conservation policies largely favor national and international actors and less so local, grassroots initiatives run by individuals and communities. Finally, we highlight the need for more accessible and inclusive policies that recognize the contribution of less powerful actors, to foster more effective conservation efforts for the future of the Amazon.</p>","PeriodicalId":51337,"journal":{"name":"Conservation Science and Practice","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/csp2.13228","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142430151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Systematic conservation planning and return on investment analysis can be helpful tools for determining where protection efforts could deliver the most efficient and effective reserve design, and supporting decision-making when trade-offs among objectives are required. Here, we propose a framework for efficient “30×30” implementation and apply it to the state of California (USA). Because conservation of a region's full suite of biodiversity is the primary objective of the global initiative, we prioritized representation in our analysis. We used Zonation to identify networks that close the gap in representation of major habitat types in California's protected area network and that also conserve the places important for biodiversity or climate change mitigation. We identified networks that are efficient relative to metrics likely to be important in implementation including land acquisition cost, number of transactions, and conservation benefit per hectare, and we illustrate not only trade-offs associated with these metrics but also differences in the co-benefits achieved. Five of the eight major habitat types in California are not currently protected at a 30% level statewide, and if representation was achieved solely through private land acquisition, targets could be met for as little as $5.84 billion, with as few as 364 transactions, or with 2.18 million additional conserved hectares. Implementation of 30×30 will likely require more flexibility than a single network design. A “no regrets” action would be to protect properties that were prioritized across all networks and additional implementation should include properties with characteristics of any of the individual networks. Our analytical framework and implementation guidance can be applied to other geographies and jurisdictions to increase the likelihood of both meeting 30×30 targets and delivering the conservation benefits they aim to secure.</p>","PeriodicalId":51337,"journal":{"name":"Conservation Science and Practice","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/csp2.13232","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142430152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We evaluate key evidence relating to the Hunting Trophies (Import Prohibition) Bill that was discussed in the UK Parliament between 2022 and 2024. We characterize the UK's role in international hunting trophy trade by analyzing CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) trade data for 2000–2021 and 2015–2021. For CITES-listed species imported to/exported from the UK as hunting trophies in these periods we use data from the International Union for Conservation of Nature (IUCN) Red List of Threatened Species to determine whether hunting designated as “trophy hunting” is (i) likely a major threat contributing to species being of elevated conservation concern, (ii) likely or possibly causing localized declines, or (iii) not a threat. We then use the Red List to determine whether such hunting provides, or potentially provides, benefits for species and/or people. Finally, we evaluate the UK Government's impact assessment of the bill. In 2000–2021 an estimated 3494 hunting trophies from 73 CITES-listed species and subspecies were exported to the UK involving an estimated 2549 whole organism equivalents (WOEs), that is, individual animals. Imports involved 158.86 ± 66.53 (mean ± SD) trophies/year (115.83 ± 32.27 WOEs/year). In 2015–2021, 79% of imports were from countries where populations of the hunted species are stable, increasing, or abundant. Legal hunting for trophies is not a major threat to any of the species or subspecies imported to the UK, but likely or possibly represents a local threat to some populations of eight species. This hunting does, or could potentially, benefit 20 species and subspecies, and people. Among other concerns, the impact assessment failed to adequately consider the costs and benefits to local communities in countries where such hunting occurs.

The spectacular monarch migration is under threat from the loss of habitat and the decline of their milkweed host plants. In the northern part of their range, roadsides could potentially produce millions of monarchs annually due to high densities of milkweed; however, roadside milkweed can accumulate chemicals from roads, such as sodium from road salt. Controlled lab studies have shown mixed effects of sodium on monarch development: small increases can be beneficial as sodium is an important micronutrient in brain and muscle development, but large increases can sometimes decrease survival. It is unclear how dietary sodium affects performance in ecologically relevant conditions and the migration itself. In this experiment, we raised monarchs outdoors, in migration-inducing conditions, on milkweed sprayed with three levels of sodium chloride. We released 2464 tagged monarchs and held an additional 246 for further lab assays. While our recovery rates to the wintering grounds were low (<i>N</i> = 7 individuals), individuals from all three sodium chloride treatments made it to Mexico.
