Practitioner Insights into Weed Management on California’s Rangelands and Natural Areas
14. Dezember 2019
Abstract Working rangelands and natural areas span diverse ecosystems and face both ecological and economic threats from weed invasion. Restoration practitioners and land managers hold a voluminous cache of place-based weed management experience and knowledge that has largely been untapped by the research community. We surveyed 260 California rangeland managers and restoration practitioners to investigate invasive and weedy species of concern, land management goals, perceived effectiveness of existing practices (i.e., prescribed fire, grazing, herbicide use, and seeding...
A Heuristic Method for Determining Changes of Source Loads to Comply with Water Quality Limits in Catchments
13. Dezember 2019
Abstract A common land and water management task is to determine where and by how much source loadings need to change to meet water quality limits in receiving environments. This paper addresses the problem of quantifying changes in loading when limits are specified in many locations in a large and spatially heterogeneous catchment, accounting for cumulative downstream impacts. Current approaches to this problem tend to use either scenario analysis or optimization, which suffer from difficulties of generating scenarios that meet the limits, or high complexity of...
Searching for Networks: Ecological Connectivity for Amphibians Under Climate Change
12. Dezember 2019
Abstract Ecological connectivity depends on key elements within the landscape, which can support ecological fluxes, species richness and long-term viability of a biological community. Landscape planning requires clear aims and quantitative approaches to identify which key elements can reinforce the spatial coherence of protected areas design. We aim to explore the probability of the ecological connectivity of forest remnants and amphibian species distributions for current and future climate scenarios across the Central Corridor of the Brazilian Atlantic Forest...
Critical Review of Exposure and Effects: Implications for Setting Regulatory Health Criteria for Ingested Copper
12. Dezember 2019
Abstract Decades of study indicate that copper oral exposures are typically not a human health concern. Ingesting high levels of soluble copper salts can cause acute gastrointestinal symptoms and, in uncommon cases, liver toxicity in susceptible individuals with repeated exposure. This focused toxicological review evaluated the current literature since the last comprehensive reviews (2007–2010). Our review identified limitations in the existing United States and international guidance for determining an oral reference dose (RfD) for essential metals like copper. Instead...
Informal Emptying Business in Mandalay: Its Reasons and Financial Impacts
11. Dezember 2019
Abstract Globally, 2.8 billion people use on-site sanitation facilities, which need regular emptying of accumulated fecal sludge. Illegal dumping from informal emptying businesses, one of the major challenges in environmental management, is widely observed. Considering Mandalay, Myanmar, this study aimed to determine why informal emptying businesses are selected and estimate the lost revenue for a formal emptying service provider (FP) due to the informal businesses. We interviewed 400 households on their recognition and experiences regarding emptying services and...
Determinants of Landscape Irrigation Water Use in Florida-Friendly Yards
11. Dezember 2019
Abstract Efforts to mitigate outdoor water use in Florida’s urban landscapes increasingly include promotion of regionally appropriate landscaping based on its documented effectiveness. Targeted initiatives, however, require an understanding of mechanisms underpinning low irrigation use in single-family homes with Florida-Friendly Landscaping (FFL). This paper reports survey research conducted in southwest Florida to identify factors associated with irrigation practices among FFL clients. Results indicate that approximately half of survey participants irrigated less...
Cleanup and Complexity: Nuclear and Industrial Contamination at The Santa Susana Field Laboratory, California
11. Dezember 2019
Abstract Environmental contamination, a legacy of industrial activity borne by numerous sites around the world, poses health risks for surrounding communities and presents serious cleanup challenges. One such site, the Santa Susana Field Laboratory (SSFL), served as an aerospace and nuclear energy research facility for over 50 years, during which time radioactive and other hazardous materials were unintentionally and intentionally released into the surrounding environment. These releases, including the partial meltdown of a sodium reactor, were hidden from the public for...
Citizen-Science and Participatory Research as a Means to Improve Stakeholder Engagement in Resource Management: A Case Study of Vietnamese American Fishers on the US Gulf Coast
07. Dezember 2019
Abstract This study examines the engagement of Vietnamese American commercial fisheries stakeholders in the US Gulf Coast with state and federal agencies and the role that citizen science and participatory research may play in improving this engagement. Using a mixed methods study including surveys, interviews, and focus groups, findings highlight language, lack of trust, and outreach misfit as key barriers to engaging Vietnamese American stakeholders as demanded for collaborative resource management or co-management. However, findings also demonstrate the potential role...
Effects of Mowing and Prescribed Fire on Plant Community Structure and Function in Rare Coastal Sandplains, Nantucket Island, MA, USA
04. Dezember 2019
Abstract Coastal sandplains provide habitat for a suite of rare and endangered plant and wildlife species in the northeastern United States. These early successional plant communities were maintained by natural and anthropogenic disturbances including salt spray, fire, and livestock grazing, but over the last 150 years, a decrease in anthropogenic disturbance frequency and intensity has resulted in a shift towards woody shrub dominance at the expense of herbaceous taxa. This study quantified the effects of more than a decade of dormant season disturbance-based vegetation...
Proposal for a National Blueprint Framework to Monitor Progress on Water-Related Sustainable Development Goals in Europe
03. Dezember 2019
Abstract The 17 Sustainable Development Goals (SDGs) underpinned by 169 targets presents national governments with huge challenges for implementation. We developed a proposal for a National Blueprint Framework (NBF) with 24 water-related indicators, centered on SDG 6 (clean water and sanitation for all), each with a specific target. We applied the NBF to 28 EU Member States (EU-28) and conclude that: The current SDG 6 indicators are useful for monitoring...
Measuring Recreation Benefit Loss under Climate Change with Revealed and Stated Behavior Data: The Case of Lac Saint-Pierre World Biosphere Reserve (Québec, Canada)
01. Dezember 2019
Abstract Based on a case study carried out on the Lac Saint-Pierre (LSP) World Biosphere Reserve (Québec, Canada), this paper estimates ecosystem service loss, more precisely the loss related to cultural and recreational activities of the LSP due to the fall of its water level under the pressure of climate change. We measure two dimensions of this loss. As a first step, the extrapolation of our representative survey reports $100 million annual loss in terms of recreation revenue due to the trip reduction to LSP, which is about 60% of current level. Subsequently, the...
Differences in Spatiotemporal Patterns of Vehicle Collisions with Wildlife and Livestock
01. Dezember 2019
Abstract Road ecology research has tended to focus on wildlife-vehicle collisions (WVCs) while omitting or failing to differentiate domestic (i.e., livestock) animal-vehicle collisions (DAVCs). This has limited our understanding of where, when, and how frequently DAVCs occur, and whether these patterns differ from those for WVCs. We used a 10-year collision data set for the U.S. state of Montana to compare temporal and spatial patterns of DAVCs versus WVCs at multiple scales. WVCs exhibited two diel peaks (dawn and dusk) versus only one prominent peak (late...
Implementation of the Water Framework Directive: Lessons Learned and Future Perspectives for an Ecologically Meaningful Classification Based on Phytoplankton of the Status of Greek Lakes...
01. Dezember 2019
Abstract The enactment of the Water Framework Directive (WFD) initiated scientific efforts to develop reliable methods for comparing prevailing lake conditions against reference (or nonimpaired) states, using the state of a set biological elements. Drawing a distinction between impaired and natural conditions can be a challenging exercise. Another important aspect is to ensure that water quality assessment is comparable among the different Member States. In this context, the present paper offers a constructive critique of the practices followed during the WFD...

Toxic Site Identification Program in Azerbaijan
01. Dezember 2019
Abstract The need to protect communities from hazardous waste is an important agenda for any nation. Although pollutant management and policy development are attempted in many developing countries, it is not always successful due to limited funds, project resources, and access to trained experts to conduct toxic site identification projects. For this reason, Pure Earth created the Toxic Site Identification Program (TSIP). The goal of the TSIP program is to provide reliable information and data that identifies location of toxic sites and the level of toxic severity. TSIP...
Assessing the Establishment and Implementation of Environmental Flows in Spain
01. Dezember 2019
Abstract The alteration of natural flows due to water withdrawals and the presence of hydraulic infrastructure poses significant threats to the integrity of riverine ecosystems. The establishment of environmental flows (EF) has been conceived as a water management tool to mitigate the impact of in-stream flows alteration. To date, a large body of literature has focused on methods to define EF, but less attention has been paid to documenting and assessing their actual implementation on the ground. This article provides a framework to describe and assess the process of...
