Ecological connectivity in the River Lérez Basin (Galicia, NW Spain), including three Natura 2000 sites: River Lérez, Serra do Cando, and Serra do Candán, was assessed. Land cover maps for the years 2013 and 2023 were created using Landsat 8-9 images and the random forest machine learning method. Hardwood forest habitat patches and ecological corridors were identified. Betweenness Centrality (BC) metric, along with other global structural connectivity indices such as Integral Connectivity Index (IIC), Connectivity Probability (CP), and Equivalent Connectivity (EC), were calculated. iNaturalist records were then downloaded to observe how the distribution of records resembled that of habitat and corridors for 2023. Some indices, such as the splitting patch index (SPLIT), effective meshsize (EM), edge length (EL), and edge density (ED), were also calculated at the patch level. Results showed that the area of hardwoods increased by 2.16% across the basin. The spatial patch patterns were similar in both years. Additionally, hardwood structural connectivity appeared to have improved over the study period, with IIC rising in 20.00%, PC increase by 16.67-18.92%, and EC 8.04-8.68%. However, some patches from 2013 had higher BC values due to the loss of certain connections. iNaturalist record distribution showed similarities with habitat patch and path distribution, with a lower average distance (406.06 m) compared to random points (854.12 m) for 2023. The patch indices indicated a reduction in fragmentation, with SPLIT decreasing by 53.95%, EM and EL increasing by 173.66% and 14.21%, respectively, while ED decreased by 9.29%. The integration of satellite imagery has been proven effective for generating land cover data for connectivity analysis. It also demonstrates that indices and graph-based approaches offer a data-efficient alternative to traditional models. Furthermore, the incorporation of citizen science platforms, despite some biases, complements technical methods by providing real-world insights into species distribution. This combination is considered a promising approach for future research.</p>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144315686","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 addition to the primary intended initial benefit, (protecting drinking water quality to prevent typhoid and similar disease outbreaks), additional benefits included reduced flooding, improved and more stable yield, reduced water treatment costs, and protection of native ecosystems. In relation to the latter benefit, over that period, much of the Australian landscape has been modified for various forms of development and recreational activities, leaving these water catchments as some of the last broad areas of remnant habitat for vulnerable and endangered ecosystems and species. Despite these widely appreciated and well-understood benefits, there has been continuous pressure from a diverse range of interest groups to open these areas. As government-owned organisations, the Australian water utilities consider all such requests from the community. Among the interest groups that make representations to access drinking water sources are a wide range of recreators. Pressure from such groups is increasing as populations grow. To help inform decisions on how to respond to such representations, this study predicted gastrointestinal disease burdens from recreation on a currently protected drinking water supply reservoir in Australia. This study considered a range of scenarios, described in terms understandable to the community, and predicted health implications using screening-level quantitative microbial risk assessment (QMRA). The assessment was limited to microbial risks to drinking water quality - risks from chemical or physical hazards were not considered, nor was ecosystem protection. The QMRA predicted that six reasonably foreseeable scenarios could result in microbial risks that exceeded the health-based target benchmark given in the Australian Drinking Water Guidelines (ADWG). Therefore, additional water treatment would be required to reduce those risks to acceptable levels. However, even with the introduction of additional treatment, permitting increases in the levels of recreational activity in the source water was found to be inconsistent with many of the Guiding Principles of the ADWG and with a landmark state Supreme Court planning decision that had interpreted how those principles should be applied in drinking water catchments. Therefore, the results did not support permitting recreational access to the reservoir, and the importance of source protection was reinforced.</p>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144300889","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}

Recent global goals focus on '30 × 30': extending conservation spaces to 30% of the globe by 2030, rendering the question of how to deal with the many people that inevitably live on these lands acute. While not solely reliant on protected areas, this approach incorporates various land types to meet this target, potentially including restrictions on its use. In India, acquiring land for elephant corridors is one example of extending conservation spaces into surrounding agrarian landscapes. This research investigates such a case in South India where farmers whose lands are identified for acquisition already struggle with challenges in the agrarian landscape, including neglect of agriculture by the state, rising financial debt, uncertain and changing weather patterns. Land use restrictions around protected areas, along with lack of compensation for wildlife-induced crop losses, have increased livelihood pressures, forcing farmers to diversify their income sources. Building on the conservation and agrarian literature, this article posits the concept of the 'Conservation-Agrarian Squeeze' (CAS) to make sense of the dual forces acting on farmers. This concept describes cases where land enclosure for conservation beyond PAs is facilitated by distress in agrarian landscapes. It also engages with and builds on existing terms such as the grab, induced volition, rendering surplus, and expulsion.</p>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144223945","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}

Managing these expanding species is a challenge because the factors that influence population dynamics vary with weather. The challenge is even greater for game specie, as other human factors must be considered. The wild turkey naturally expanded its distribution northward into southern Quebec, without humans transplanting turkeys from other regions. However, the northern expansion is currently limited by extreme weather events. We used matrix modelling to explore the respective and interactive effects of weather and harvest levels on demographic parameters of three populations at different expansion stages but all at the northern edge of the species distribution. Our results suggest that populations at the expansion front (fast-paced life history) can sustain higher hunting rates than well-established populations (slow-paced life history), but that the proportion of adult males declines more rapidly in response to a given level of harvest. Furthermore, populations at the expansion front under harsh to extreme conditions could not tolerate any level of harvest. Finally, fall hunting had the greatest influence on population dynamics mainly because harvesting of all females is permitted, while spring hunting is restricted to bearded birds only (<1% of turkeys harvested in spring are bearded hen). Optimal hunting regimes for populations at the limit of their distribution vary with weather and expansion stages. A conservative solution would be to allow fall hunting only in well-established populations, but adaptive management where fall harvest at the expansion front would be implemented during more mild winters. Our model approach is relatable to the very many populations currently expanding poleward in response to climate change by considering different adaptive management policies in established and expanding populations.</p>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144140977","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}

Our objective was to evaluate factors affecting WVC location and intensity across New Hampshire, USA, with a focus on habitat connectivity. We assessed the relationship between WVCs and five connectivity models using generalized additive models and compared connectivity effects to road and land cover characteristics. We found that a barrier-sensitive wildlife species connectivity model was the best predictor of WVC hotspots and had a strong, negative nonlinear relationship with collision intensity. We also found that a simple forest variable performed almost as well as the complex connectivity model. WVC hotspots did not differ from adjacent roads or regional roads in terms of connectivity, except that traffic volume was higher at hotspots. Our findings suggest that the relationship between habitat connectivity and WVCs depends on broader landscape context and likely exhibits nonlinearity. Our work also demonstrates that some connectivity models are better predictors of WVCs than others, emphasizing the role of species-specific habitat connectivity assessments.

The purpose of the program was to develop cumulative effects assessment monitoring frameworks for six different watersheds across Canada. In this paper, we evaluated the impact of the CWRC on the capacity for decision-making in these watersheds using an adapted Research Contribution Framework as a methodological guideline. Data were collected through 14 semi-structured interviews and a document analysis of eight primary CWRC reports along with secondary information (57 journal publications). From the interviews, primary documents, and a scoring exercise, we found that the CWRC was successful in contributing to research uptake and research use, but that it may have fallen short in its overall research impact. We determined that some nodes (Muskoka, Northumberland Strait, Slave River) were able to institutionalize their cumulative effects monitoring frameworks in that an organization continues to collect data that will be used to inform policy and management. Factors contributing to research contribution included strong leadership and interest from governments and communities for maintaining at least some aspects of the monitoring program beyond the end of the Consortium.
