“…Many experts and scholars have put forward different definitions [8,9] and various indicators [10][11][12] to analyze ecosystem health. Ecosystem health research has tended to examine single-ecosystem scales, such as forests [13,14], wetlands [15,16], river basins [17][18][19], marine environments [20,21], farmlands [22,23], mines [24], and cities [25][26][27]. Research on regional, multi-ecosystem scales have only begun to emerge in recent years.…”

Abstract:The purpose of this study is to propose a GIS-based mechanism for diagnosing karst rocky desertification (KRD) ecosystem health. Using the Huajiang Demonstration Area in Guizhou Province as a case study, this research offers a multi-factor indicator system for diagnosing KRD ecosystem health. A set of geologic, environmental, and socio-economic health indicators were developed based on remote sensing images from field-investigation, hydrological, and meteorological monitoring data. With the use of grid GIS technology, this study gives an indicator for diagnosing the spatial expression of desertification at a 5 m × 5 m grid scale. Using spatial overlaying technology based on grid data, the temporal and spatial dynamics of ecosystem health in the Huajiang Demonstration Area were tracked over a 10 year time span. The results of the analysis indicate that ecosystem health in the Huajiang Demonstration Area varies regionally, and has overall improved over time. The proportion of healthy area increased from 3.7% in 2000 to 8.2% in 2010. However, unhealthy and middle-health areas still accounted for 78.7% of the total area by 2010. The most obvious improvement of ecosystem health was in an area where comprehensive control measures for curbing KRD were implemented. These results suggest that comprehensive control of KRD can effectively mitigate ecosystem deterioration and improve ecosystem health in karst regions of South China.

“…But as may be expected, there is no single indicator that fully captures the health or integrity of an entire ecosystem and thus could function as a metric of restoration success. For instance, Ogden et al (2014) recommended using the abundance of a suite of waterbirds as an indicator of ecosystem health in the coastal marine environment of South Florida, while Harvey et al (2011) and Mazzotti et al (2008) concluded that American alligator abundance is "an indicator of ecosystem responses to Everglades restoration because it is sensitive to hydrology, salinity, and system productivity, all factors that are expected to change as a result of restoration." The Science Coordination Team of the South Florida Restoration Task Force established by the U.S. Congress has recommended eleven system-wide ecological indicators in order to understand how the ecosystem is responding to management efforts under the CERP (http://141.232.10.32/pm/ recover/perf_ge.aspx).…”

• Develops an integrated methodology linking Everglades hydrology to economic values • First ever estimate of anglers' willingness to pay for Everglades recreational experience • Estimates losses in economic welfare due to missing freshwater delivery targets and implicit price of water use for recreation at $41.54 AF -1 • Relevant applications to management, restoration, and climate scenario analysis This research develops an integrated methodology to determine the economic value to anglers of recreational fishery ecosystem services in Everglades National Park that could result from different water management scenarios. The study first used bio-hydrological models to link managed freshwater inflows to indicators of fishery productivity and ecosystem health, then link those models to anglers' willingness-to-pay for various attributes of the recreational fishing experience and monthly fishing effort. This approach allowed us to estimate the foregone economic benefits of failing to meet monthly freshwater delivery targets. The study found that the managed freshwater delivery to the Park had declined substantially over the years and had fallen short of management targets. This shortage in the flow resulted in the decline of biological productivity of recreational fisheries in downstream coastal areas. This decline had in turn contributed to reductions in the overall economic value of recreational ecosystem services enjoyed by anglers. The study estimated the annual value of lost recreational services at $68.81 million. The losses were greater in the months of dry season when the water shortage was higher and the number of anglers fishing also was higher than the levels in wet season. The study also developed conservative estimates of implicit price of water for recreation, which ranged from $11.88 per AF in November to $112.11 per AF in April. The annual average price was $41.54 per AF. Linking anglers' recreational preference directly to a decision variable such as water delivery is a powerful and effective way to make management decision.

“…In particular, wetland birds may be excellent indicator species because their biology and ecological roles in the functioning of wetland ecosystems is well understood (Becker ; Green & Elmberg ; Ogden et al. ) and glyphosate residues and AMPA are known to be present in wetlands (Battaglin et al. ; Mañas et al.…”

Glyphosate has become the most commonly used herbicide worldwide, with a reputation of being environmentally benign, non-toxic and safe to wildlife and humans. However, studies have indicated its toxicity has been underestimated, and that its persistence in the environment is greater than once thought. Its actions as a neurotoxin and endocrine disruptor indicate its potential to act in similar ways to persistent organic pollutants (POPs) such as the organochlorine (OC) chemicals dichlorodiphenyltrichloroethane (DDT) and dioxin. Exposure to glyphosate and glyphosate-based herbicides for both wildlife and people is likely to be chronic and at sub-lethal levels, with multiple and ongoing exposure events in both urban and agricultural landscapes. Despite this, little research attention has been given to the impact of glyphosate on wildlife populations, and existing studies appear in the agricultural, toxicology and water chemistry literature that may have limited visibility among wildlife biologists. There is a strong case for the recognition of glyphosate as an 'emerging organic contaminant' and significant potential exists for collaborative research between ecologists, toxicologists and chemists to quantify the impact of glyphosate on wildlife and to evaluate the role of biosentinel This article is protected by copyright.

Success will depend on the development of new and novel non-destructive sampling and analysis methodologies as ex post facto identification of toxins at lethal levels has limited utility. Concentrating on the chemistry and toxicity of glyphosate, we have examined the published literature to evaluate the extent to which glyphosate based herbicides can cause toxic effects in wildlife and people and the implications of chronic exposure. We then explore the idea of using birds as bioindicators of glyphosate toxicity. We hope this may encourage future research into the uptake and impact of organophosphate chemicals in target species, particularly traditional indicator species such as birds.
