Observadores del Mar (OdM) is the leading platform for marine citizen science in Spain and works towards ocean conservation and health. It is a well-established tool for generating knowledge in marine research and has successfully provided early warning of NIS reports in the Mediterranean, while also serving as an effective network for the monitoring of NIS and other indicators. Three reports of C. andromeda from Almeria, southern Spain, have been reported in OdM and thanks to the involvement of its community, 12 samples were collected for phylogenetic analysis and monitoring was done for 15 months in the study area. The results confirmed the first record of C. andromeda in Spanish Mediterranean waters representing the westernmost record in the basin. Monitoring also suggests the species establishment in the area. This study contributes to the knowledge of C. andromeda invasiveness and highlights the importance of marine citizen science in the detection and monitoring of NIS.

Sphagnum moss as a potentially renewable alternative for peat is an emerging raw material in the horticultural growing medium industry - hence Sphagnum is harvested or farmed in multiple countries worldwide. In Finland, Sphagnum harvesting is a new land use of peatlands, currently conducted on a small scale, preferentially on sites previously affected by other types of land use. However, with ample suitable harvesting areas available, such as forestry drained peatlands with low timber production, Sphagnum harvesting has the potential to become a significant land use practice. To assess the available Sphagnum harvesting land resources in Finland, we employed collaborative working methods, including repeated workshops with stakeholders and semi-structured interviews to establish criteria for site selection. Through stakeholder engagement, the criteria were selected, further modified, and used in spatial analysis to delineate potential harvesting areas and estimate land area. The criteria formulation involved several stages, including identifying existing land-use restrictions and other possible constraints on peatlands, and assessing where suitable Sphagnum yield and production costs can be achieved. The resulting area estimate ─ 241,000 hectares of potential Sphagnum harvesting area ─ is substantial, accounting for up to 3% of all peatland areas in Finland. It also exceeds the estimated area needed for Sphagnum harvesting to replace peat as a growing medium in Finland. The stakeholder engagement process revealed the need for further regulation of Sphagnum harvesting if the activity is upscaled.</p>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145197631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While traditional flood management emphasizes disaster prevention through structural interventions, it often overlooks the ecological functions of flood pulses. This study first explores how flood frequency and phases affect riverine habitat quality, integrating two-dimensional hydrodynamic modeling with ecological habitat assessment. Using the Qingyi River as a case study, we quantified the habitat responses of multiple aquatic organisms under different flood frequencies and different hydrological stages. Results show that moderate floods (with a 10-year return period) enhanced fish habitat functionality (Weighted Usable Area, WUA) by up to 120% compared to multi-year average discharge, primarily by expanding shallow zones and improving lateral connectivity. Fish species reached peak habitat suitability during flood crests, while Benthic organisms favored recession phases, revealing phase-specific ecological responses. To further account for flood risks-often neglected in ecological evaluations-we introduced a Flood Assessment Method Coupling Ecology and Risk (FAMCER) and in this method we proposed the Flood Efficiency Index (FEI) to integrate ecological gains and hazard costs. This index identifies trade-offs between ecological benefits and flood risks, showing that 10-year floods achieve an optimal balance in our case study. The flexible FEI-based framework enables targeted evaluation across different conservation priorities and supports adaptive decision-making for ecological flow releases and floodplain restoration. These findings highlight the need to shift from purely defensive flood control to integrated flood management that balances ecological enhancement with risk mitigation.</p>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145172157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Germany, current fertilizer policies rely on rigid, action-oriented guidelines that stakeholders increasingly criticize for failing to address complex environmental challenges. This study captures policy demands for improved nutrient management by engaging primary stakeholders-from agriculture, environmental protection, and academia-through a modified policy Delphi process. Iterative online working groups and a plenary scenario workshop, structured around a systematic framework on environmental policy instrument selection, elicited open-ended, demand-driven responses. Findings reveal a strong consensus for shifting from prescriptive fertilization practices to target-oriented, scientifically grounded approaches. Stakeholders advocate adopting farm-gate nutrient balancing to reduce nitrogen losses and manage phosphorus surpluses while emphasizing the need for robust monitoring systems enhanced by digital technologies. This participatory approach integrates diverse expert perspectives into policy recommendation, enhancing the legitimacy and adaptability of future fertilizer policies while reducing political dissent. Although these stakeholder-driven recommendations offer promising directions for reconciling agricultural productivity with environmental sustainability, further empirical research-including pilot projects and simulation studies-is needed to validate feasibility and refine the methodological framework.
