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}

Finally, we review historical data to determine if conditions have changed in either the spring or summer burn seasons over 42 years. Although burn severity generally declined with fuelbed greenness in the spring, summer burns could effect as high of severity as spring burns despite having greener fuelbeds. What little phenological change seems to have occurred at the study location over 42 years-slightly greener fuelbeds and slightly lower relative humidity in spring-likely offset each other to some degree.

However, little information is available on the status of individual streams at fine-scale geographic levels. To address this issue, we evaluated air and in-stream temperature time-series over a seven-year period among 10 streams on Laurel Hill in southwestern Pennsylvania. Thermal sensitivity (E, the slope of the air-instream temperature relationship) was calculated for each stream during the Brook Trout growth seasons (April-September) to determine potential effects on resident fish. Values of E varied interannually within and among streams in terms of annual maximum growth season temperatures, days of Brook Trout thermal stress (>18 °C), and estimated number of days to hatch. A value of E approximating 0.42 served as an inflection point above which periods of thermal stress rose sharply. E was also positively related to estimated days to hatch. Overall, the data from this study document differing responses to warming from streams as close as 2 km apart, suggesting a need for conservation measures at a local level. The use of paired in-stream and riparian temperature data loggers provides an inexpensive way to identify and to monitor streams that may be particularly vulnerable to warming. Data from this study indicated that warming has detrimental implications for resident eastern Brook Trout and, without consideration of groundwater and riparian canopy protection, along with revised stocking paradigms, continuing existential impacts can be expected. Identifying which streams are most susceptible to warming impacts on Brook Trout using a simple metric, such as thermal sensitivity, will allow for more targeted conservation efforts by fishery/watershed managers to protect this at-risk native species.</p>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144232888","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}

Biological systems, by contrast, typically demonstrate truly spectacular resilience, evidenced by the capability to self-repair deterioration and injury over millennia. Definitions of resilience commonly assemble multiple concepts describing the achievement of 'resilience' and the means by which this is achieved. Breaking down these concepts as they are applied to biological and technological systems allows useful analysis of the concepts that inhibit or promote resilience in technological systems.

We present a method to predict climate-driven shifts in target attribute states for suspended and deposited fine sediment, as specified in existing environmental policy for Aotearoa-New Zealand. The policy uses a river environment classification derived from climate, topography, and geology inputs to determine spatially-distributed target attribute states. We calculated and mapped class membership of the classification and resulting target attribute states for future climate scenarios from regional projections. Apparent spatial patterns in shifts to warmer and drier climate classes are anticipated for a considerable proportion of river segments under the highest future emissions scenario towards the end of century. Climate-driven shifts in class membership led to shifted target attribute states corresponding to either increased or decreased sediment targets depending on location, and the emergence of conditions that have no specified environmental targets because they fall outside of existing classes. Findings highlight the potential impact of climate change upon both target attribute states and actual fine sediment states which should be considered when devising environmental classifications and setting target attribute states.

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}
