The concept of ecological integrity is increasingly being used to guide monitoring efforts across North American public land agencies. We provide a history of this concept and outline its primary components on the basis of the scholarly literature. We then examine established structures
Predating definition of integrity processes that incorporate the best available science, spatial and temporal concerns, and management relevance into frameworks for measuring and reporting on ecological integrity.
To understand how this is applied in practice, we provide examples from two land-management
Predating definition of integrity in North America that have used ecological integrity as a concept to organize their monitoring programs. Laws, agency guidance, organizational structure, and collaborative processes strongly influence the outcomes of ecological integrity—monitoring programs. Further research in this area would be valuable to better understand how different types of land-management agencies can effectively monitor ecological integrity across various spatial and temporal scales and in the context of climate change.
Effectively monitoring and reporting on ecological conditions is a crucial component of natural-resource management. Tracking progress toward management goals requires a consistent monitoring program and the development of benchmarks and thresholds for assessing management actions on a continual basis Harwell et al.
A well-designed monitoring program can also help to detect trends in resource conditions, threats to resources, and the effectiveness of mitigation or adaptation strategies, both of which are important as resources are affected by climate change SpellerbergLarson et al. Increasingly, land-management agencies, often in response to new legal requirements, are employing the concept of ecological integrity to facilitate and structure their monitoring efforts. Internationally, the concept has been promoted and used as a guiding framework for restoration and monitoring efforts in protected areas Timko and InnisKeenleyside et al.
In North America, ecological integrity increasingly is being recognized as an appropriate framework for measuring and communicating progress toward conservation and restoration goals BarbourParrish et al. For instance, the US Forest Service uses ecological integrity as a concept to guide its assessment, land-use planning, and monitoring of forest ecosystems. It is important for managers and stakeholders to understand the scientific foundations of ecological integrity and to operationalize it in a way that captures the complexity of the concept and also is measurable, of relevance to managers, and can be understood and supported by stakeholders and the public.
To support improved practice in light of new policy requirements, we conducted a review of the scientific literature defining ecological integrity and looked at strategies for identifying and prioritizing
Predating definition of integrity objectives for ecological integrity and communicating outcomes. In particular, we describe the structures and processes that incorporate the best available science, spatial and temporal concerns, and social and managerial priorities into an operational framework for measuring and reporting on ecological integrity.
We also look at how the concept has been applied in practice by two land-management agencies in order to highlight the practical applications and tradeoffs that occur when organizations use different strategies for monitoring ecological integrity at multiple scales.

The notion of ecological integrity is not new. Decades later, the maintenance of biological integrity and ecological integrity were enshrined as legal mandates under the US Clean Water Act of and the Parks Canada Act ofspurring significant academic debate about the meaning and practical application of the concept see Woodley et al.
Since the late s, practical and measurable approaches to ecological integrity in

Today, ecological integrity is most commonly understood as a holistic concept and framework that focuses on conserving native biodiversity, using the natural or historic range of variation as a reference point, and promoting resilience i. Ecological integrity emphasizes the importance of ecological processes such as natural disturbance regimes that provide the structures and functions on which the full complement of species in an ecosystem or landscape depend Angermeier and "Predating definition of integrity"Andreasen et al.
Furthermore, ecological systems that retain their native species and natural processes are hypothesized to be more resistant and resilient to natural and anthropogenic stresses over time Parrish et al. Ecological integrity frameworks also typically emphasize the intrinsic value of native biodiversity, beyond its functional role in supporting the renewal and reorganization of ecosystem function and

Ecological integrity is commonly characterized in terms of the ecological components of composition, structure, and function at multiple levels of hierarchical organization, from species to landscapes Andreasen et al.

Predating definition of integrity biotic interactions, such as herbivory and predation; biological processes, such as primary productivity; and abiotic processes, including hydrological processes and fire regimes Dale and Beyeler Evaluating ecological integrity requires an understanding of the dynamic spatial and temporal relationships, links, and interactions among ecosystem components at multiple levels of the ecological hierarchy.
A rigorous, scientifically based understanding of an ecosystem facilitates the identification of the key attributes of composition, structure, and function that are most crucial for biodiversity conservation and ecological resilience. For example, key attributes of composition or biodiversity may be species or functional groups of species e. Processes such as fire also may be considered key attributes.
In addition to composition, structure, and function, it is often also helpful when building a conceptual model of ecological integrity to characterize the ecological drivers, such as climate regimes or geology, that determine or influence the variation in ecological components Parrish et al. In some applications, dominant disturbance regimes are also characterized as drivers in order to more clearly illustrate the role of critical-ecosystem processes and their effects on other attributes see Mitchell et al.
The identification of the key attributes of ecological integrity requires the specification of spatially explicit ecosystems or landscapes for assessment and measurement. The subjective nature of ecological boundaries can make identifying focal ecosystems challenging. Although an ecosystem may be defined on the basis of management goals or compositional
Predating definition of integrity such as dominant vegetation, it also must take into consideration the spatial Predating definition of integrity temporal scales of dominant processes and interactions across the wider landscape Andreassen et al.
A nested, multiple-scale approach for evaluating ecological integrity at both the ecosystem and landscape level may be essential for ecological systems in which cross-scale interactions and processes, such as large-scale disturbances, are particularly relevant for native biodiversity or ecological function. In order to assess and measure ecological integrity, it is useful to compare the current state and ranges of variation in ecosystem components with desired states and ranges of variation through the use of benchmarks or reference points.
This is done to evaluate the influence of anthropogenic or biological stressors on key ecosystem attributes and assess progress toward management goals, such as restoration Karr and ChuParrish et al.
There are different approaches for determining benchmarks and reference points, each with relative strengths and weaknesses.
One approach relies on the use of historical ecology to identify the natural or historic range of variation. Assessing HRV requires reconstructing and interpreting historic conditions
Predating definition of integrity the range of variability in those conditions from limited, often site-specific data sources that may not exist for many ecosystems.
Climate change also complicates the use of HRV as a benchmark for ecological integrity, because shifting species distributions and disturbance interactions may produce novel ecosystems without historical analog.
Furthermore, HRV may also be inappropriate for irrevocably degraded systems, or systems in which restoration to HRV is not socially acceptable or feasible Safford et al. That being said, using HRV as a benchmark for ecological integrity may still be useful for assessing or evaluating restoration actions in modified ecosystems, such as southwestern Ponderosa pine forests, where the restoration of historic disturbance regimes and forest structures is predicted to increase resilience to climate-related stressors, such as drought, insects, and disease outbreaks Fule Furthermore, understanding HRV is crucial for providing context about the temporal dynamics and distribution of ecosystems, including the variation and interactions among ecological processes, climatic drivers, stressors, and ecosystem
Predating definition of integrity, and offering insight into relevant ecological thresholds that may result in state changes Safford et al.
Another approach uses reference conditions in pristine or relatively pristine ecosystems to evaluate and compare ecological attributes in more degraded systems.
The ecological attributes of stream systems in undegraded or protected areas have been widely and successfully used to evaluate the effects of human development and use in more managed watersheds or landscapes Karr and Chu By using existing reference conditions, the relative ecological integrity of ecosystems may be evaluated over time, allowing inference into the effects of human use or management actions, even when, given the effects of climate change, returning to historic conditions may not be the goal Hanberry et al.
However, reference conditions must be chosen carefully. For example, in their survey of aquatic and riparian conditions in public lands in the interior Columbia Basin, Kershner and
Predating definition of integrity found that some ecological attributes associated with management objectives were not significantly different between reference and managed sites, potentially a legacy of historic land uses.
Where it is impractical to thoroughly evaluate an appropriate HRV or use reference conditions in undegraded systems, benchmarks may still be determined through the use of expert opinion. In addition, the reliance on a natural or historic range of variation for evaluating ecological integrity can be problematic in light of climate change, invasive species, and irrevocably altered or degraded systems Safford et al.
At the same time, ecological integrity is increasingly being recognized as an appropriate framework for measuring

A history and overview of...
By identifying and measuring key attributes of drivers, stressors, composition, structure, function, and disturbance processes, managers may set goals and evaluate trends in ecological integrity over
Predating definition of integrity see Parrish et al.
Although debates about how to define and operationalize ecological integrity will continue to evolve as managers and stakeholders work to apply the concept, ecological integrity is increasingly being used as a framework for designing and executing monitoring strategies at multiple scales. Measures of ecological integrity must be based on indicators that are useful for conveying information about the composition, structure, and function of selected ecosystems over time and across spatial scales.
Ideally, indicators should provide quantitative measures of the status and trend of key ecosystem drivers and
Predating definition of integrity, reflect
Predating definition of integrity influence of natural versus anthropogenic stressors, and serve to identify the causes of environmental change at different hierarchical levels of ecological organization Andreassen et al.
Monitoring indicators will necessarily be a subset of possible measures. This subset must provide enough information to understand the status of ecological integrity, be feasible to measure and cost effective, and provide results with sufficient statistical power for management and decisionmaking see Noon et al.
Limiting indicators is challenging, but a particularly persistent challenge is selecting indicator species for monitoring ecological integrity, because of the varying responses of species to stressors and their limited ability to represent impacts to associated taxa Carignan and Villard Indicators must also be chosen on the basis of whether they assist managers and stakeholders in understanding and communicating ecosystem status.
An indicator-selection process must also incorporate social and economic considerations, such as feasibility, relevance, cost, and acceptance Niemeijer and DegrootTulloch et al. Therefore, developing measures of ecological integrity requires prioritization, often through a deliberative process, of the world of possible measures according to criteria.
One important method for selecting indicators is the use of conceptual ecosystem models that highlight the interactions between key ecological components at different scales and the potential indicators that can be measured to assess them.
Conceptual models are necessary for clarifying causal links and feedback loops and for making explicit
Predating definition of integrity assumptions about the influence of drivers and stressors on ecological attributes.
They are also an important communication tool, useful for simplifying and conveying the current understanding about ecological systems and the effects of management to stakeholders. Because of the considerable uncertainty within ecological systems, as well as differing views and understandings between experts, the development of conceptual models should be a deliberative and inclusive process Gentile et al.
Indicators may also be identified through a Delphi process —essentially a set of sequential surveys of experts used to iteratively identify and prioritize potential indicators see Amici and Battisti —or collaborative workshops and expert-based panels Oliver These processes explicitly incorporate expert opinion and are useful for identifying, out of a long list of potential attributes and indicators, a limited number of indicators of structure, function, and composition.
Predating definition of integrity same Predating definition of integrity, collaboration with managers is essential, because indicators must provide clear and policy-relevant information for decisionmaking. Managers will be able to aid in specifying objectives and identifying indicators that will best measure progress toward desired conditions and are feasible to monitor Failing and GregoryTulloch et al.
The inclusion of stakeholders is also desirable because social legitimacy and support are often paramount for effective and consistent monitoring efforts Moir and BlockBiber A deliberative process involving the use of criteria to filter monitoring indicators can be designed to address these many issues Niemeijer and Degroot In order to provide useful guidance for policy and management, measures of ecological integrity must be articulated in a format that is accessible and can effectively communicate status and trends to both managers and the public.
One option is to develop a composite index derived from aggregated measures of different indicators that can be compared with baseline measures from high-integrity systems or historical reconstructions.

The most well-known example is the Index of Biological Integrity developed by Karr and Dudley for use in water-quality assessment, which has been used to demonstrate the influence of different stressors and provide quantitative measures of integrity in US and Canadian waterways Karr and Chu Developing composite indices for terrestrial systems is possible but has proven more difficult because of the complexity of terrestrial systems and the value judgments needed to determine the respective weights of different indicators
Predating definition of integrity. Conditions and trends are often communicated through the use of scorecards, which sometimes are required by law and have been used in various ecosystem-management and —ecosystem-restoration contexts, including the implementation of the Northwest Forest Plan, the Upper Great Lakes regional initiative, and wetland restoration in South Florida Harwell et al.
Regardless of whether ecological thresholds are known, assessment points can be based on HRV or baseline conditions to track trends and changes, can provide a signal to managers and stakeholders that further evaluation is warranted, and can represent agreed-on points at which management actions must be reevaluated or changed Groffman et al. In this section, we examine efforts to measure and report levels of ecological integrity with two land-management examples: We base all information herein on public documents describing the content of these monitoring programs, including reports and any available information on processes that the two agencies used in their development, implementation, and interpretation of monitoring requirements and programs.
We also supplemented this with several informal and confidential interviews for clarification purposes. Both of these regionally integrated monitoring programs are well known for their development of ecological-integrity monitoring for upland terrestrial systems Tierney et

Each network shares funding and staff, with five to seven full-time, professional specialists devoted to the development and implementation of the program Fancy et al. Monitoring in each inventory and monitoring network is organized under the concept of vital signs.

Data available at http: Species integrity can be challenged, and even eroded, if closely related species can hybridize and produce fertile offspring of comparable fitness to that of parental species. Ecological selection, including predation, is often presumed to contribute to reduced hybrid fitness, but field evidence for a predation cost to hybridization remains elusive. Here we provide proof-of-concept for predation on hybrids being a postzygotic barrier to gene flow in the wild.
Cyprinid fishes commonly produce fertile, viable hybrid offspring and therefore make excellent study organisms to investigate ecological costs to hybrids. We electronically tagged two freshwater cyprinid fish species roach Rutilus rutilus and bream Abramis brama and their hybrids in Tagged fish were returned to their lake of origin, exposing them to natural predation risk from apex avian predators great cormorant, Phalacrocorax carbo.
Scanning for regurgitated tags under cormorant roosts 3—4 years later identified cormorant-killed individual fish and allowed us to directly test for a predation cost to hybrids in the wild. Hybrid individuals were found significantly more susceptible to cormorant predation than individuals from either parental species.
Such ecological selection against hybrids contributes to species integrity, and can enhance species diversification.
Fostering Integrity in Enquiry. In the completion, a commitment to the ethical pedestal of truthfulness, entirely an understanding of its meaning to science, is quintessential to enhance impartiality and diminish affect unduly. Unfortunately, the ethos of concern after scientific misconduct continues to dominate the research-ethics movement. That focus is damaging because it turns the attention to seeking and discovery wrong-doers and determining punishment rather than discussing generic issues of doing the right thing, preventing harms, seeking benefits, and understanding the right-making and wrong-making characteristics of stunts.
The focus on scientific misconduct adjusts ethical issues come synonymous with proper issues and the search for principled understanding synonymous with carrying out an investigation. Integrity is essential to the functioning of the research enterprise and personally important to the vast lion's share of those who dedicate their lives to science.
Until now research misconduct and detrimental research practices are facts of life. They be required to be understood and addressed.
