RESUMEN

Advancing transformative change for sustainability requires population-wide behavior change. Yet, many behavioral interventions tackling environmental problems only examine average effects on the aggregate, overlooking the heterogeneous effects in a population. We developed and preregistered a novel audience segmentation approach to test the diverse impact of conservation messaging on reducing demand for exotic pets (private action - i.e., desire to own exotic pets or visit wildlife entertainment places) and fostering citizen engagement for system-wide change (civic action - e.g., signing a petition or participating in a protest against the exotic pet trade). Through an online survey with US participants (n = 2953), we identified 4 population segments (early adopters, early majority, late majority, and laggards), representing varying levels of commitment to wildlife conservation and then randomly assigned each segment to one of 3 messaging conditions. Messages highlighting negative consequences of the exotic pet trade and the power of collective action for system change effectively promoted private action among all segments except early adopters (ηp 2 = 0.005). Among civic actions, only the collective action message motivated early adopters and the early majority to sign petitions (φC = 0.193 and φC = 0.097, respectively). Furthermore, the 4 segments showed distinct reasoning for action and inaction on wildlife conservation, with certain relational values, such as care, serving as both motivations and barriers to action. These findings highlight the need for targeted behavioral interventions across diverse populations.


Estrategia de segmentación del público en los mensajes de conservación para transformar el mercado de mascotas exóticas Resumen El progreso en el cambio transformativo para la sustentabilidad requiere de cambios conductuales a nivel poblacional. Sin embargo, muchas intervenciones conductuales que abordan los problemas ambientales sólo analizan los efectos promedio sobre el agregado, lo que ignora los efectos heterogéneos sobre la población. Desarrollamos y preinscribimos una estrategia novedosa de segmentación del público para evaluar los diversos impactos de los mensajes de conservación sobre la reducción de la demanda de mascotas exóticas (acción privada [es decir, el deseo de poseer mascotas exóticas o visitar sitios de entretenimiento con fauna] y promover la participación ciudadana para un cambio sistémico [por ejemplo, firmar una petición o participar en una protesta contra el mercado de mascotas exóticas]). Realizamos una encuesta en línea con participantes estadunidenses (n = 2953) para identificar cuatro segmentos de la población (adoptadores tempranos, mayoría temprana, mayoría tardía y rezagados), los cuales representan diferentes niveles de compromiso con la conservación de fauna, y después le asignamos aleatoriamente a cada segmento una de las siguientes condiciones de mensaje: las consecuencias negativas del mercado de mascotas exóticas, el poder de la acción colectiva para el cambio sistémico e información neutral como control. Los mensajes que resaltaban las consecuencias negativas del mercado de mascotas exóticas y el poder de la acción colectiva promovieron de forma eficiente la acción privada en todos los segmentos excepto los adoptadores tempranos (ηp 2 = 0.005). Entre las acciones cívicas, sólo el mensaje de acción colectiva motivó a los adoptadores tempranos y a la mayoría temprana a firmar peticiones (φC = 0.193 y φC = 0.097, respectivamente). Además, los cuatro segmentos mostraron un razonamiento distinto para la acción e inacción para la conservación de fauna, con ciertos valores de relación, como el cuidado, fungiendo como motivación o barreras para la acción. Estos resultados enfatizan la necesidad de tener intervenciones conductuales focalizadas entre las diferentes poblaciones.

RESUMEN

Privately protected areas (PPAs) are a potentially innovative conservation tool. Legal recognition is necessary for their success, especially where there are institutional challenges to nature conservation, such as in South America. Although PPAs have increased in South America since the early 2000s, there is a critical information gap pertaining to their legal frameworks. We analyzed the level of landowner commitment to and governmental support for PPAs across countries in South America that officially recognize PPAs. We analyzed the legal framework governing PPAs and reviewed literature on them. This process was done in English and Spanish. The information we gathered was validated by 16 conservation experts from 10 South American countries. Because Peru is 1 of only 2 South American countries where local communities create and manage PPAs, we studied Peruvian PPAs in more detail by examining official creation documents and interviewing 13 local conservation professionals. We found inadequate minimum duration of PPAs and vague guidelines for conducting economic activities within them and a lack of governmental support (e.g., financial and technical support) for PPAs. Support was limited to the exemption from rural property taxes, which are relatively low compared with countries outside South America. In Peru, PPAs run by individuals and communities needed different legal frameworks because they were created with different objectives and had different sizes and duration of commitments. The prompt improvement of legal frameworks across South America is necessary for PPAs to achieve their aim of being places for enduring nature conservation in the region.


Una revisión legal de la conservación voluntaria entierras privadas de América del Sur Resumen Las áreas protegidas privadas (APP) son una herramienta de conservación con potencial innovador. Para ser exitosas, las APP necesitan reconocimiento legal, especialmente cuando existen obstáculos institucionales para la conservación de la naturaleza, como sucede en América del Sur. Aunque las APP han aumentado en esta zona desde principios de la década del 2000, existe un vacío de información con respecto a sus marcos legales. Analizamos el nivel de compromiso de los terratenientes y el apoyo gubernamental hacia las APP en los países de América del Sur que reconocen de forma oficial las APP. Analizamos el encuadre legal que rige a las APP y revisamos la literatura existente sobre ellas; realizamos este proceso en inglés y en español. Dieciséis expertos de la conservación de diez países sudamericanos validaron la información recopilada. Ya que Perú es uno de los dos países de la zona en donde las comunidades locales crean y manejan las APP, nos enfocamos en sus APP y examinamos a detalle los documentos oficiales de creación y entrevistamos a 13 profesionales de la conservación locales. Encontramos una duración mínima inadecuada de las APP y directrices vagas para la realización de actividades dentro de ellas, así como una falta de apoyo gubernamental (p. ej.: apoyo económico y técnico). Este apoyo se limitaba a la exención de los impuestos sobre la propiedad rural, los cuales son relativamente bajos en comparación con los países fuera de América del Sur. En Perú, las APP a cargo de individuos y comunidades necesitaban diferentes encuadres legales porque fueron creados con diferentes objetivos y tenían diferentes tamaños y plazos para los compromisos. Se necesita una rápida mejora de los marcos legales en América del Sur para que las APP logren el objetivo de ser sitios para que perdure la conservación de la naturaleza en la región.

RESUMEN

BACKGROUND: Patient-ventilator dyssynchrony is commonly due to patient pathophysiologic factors and imprecise ventilator settings. In unusual circumstances, such dyssynchrony can also be due to faults within the equipment preventing from its normal operation during assisted mechanical ventilation. CASE DESCRIPTION: We report a patient showing an unusual pattern of dyssynchronous breathing related to a blocked scavenging system caused by the failure of its rod valve to open. Collection of water condensate inside its reservoir bag leading to a weight drag and deformation of its shape was found to be the cause. Specifically, our patient manifested as failure to trigger with the development of high positive end-expiratory pressure (PEEP) and paradoxical pressure changes during pressure support ventilation. CONCLUSION: Water condensation distal to the ventilator exhaust gas outlet may not be immediately apparent. Clinicians should remain alert with patient-ventilator dyssynchrony, especially with an unusual pattern, as it may signify equipment faults, such as expiratory gas flow obstruction within the scavenging system.

RESUMEN

Our paper, "The Insignificance of Thresholds in Environmental Impact Assessment: An Illustrative Case Study in Canada" received a critique that challenged us on a number of grounds. Namely, that we defame EIA practitioners, that we advocate EIAs to become a scientific enterprise, that we do not recognize the complexity inherent in EIA, and that EIA undergo an independent assessment by regulators. We respond to all of these points, and argue that conflict of interest is an institutional issue (not one of corrupt practitioners), and that we critique the science that forms the basis of evidence in EIA. Further, we show that the complexity and uncertainty in the critique cannot explain the findings from our paper that all cases of impact threshold exceedance were determined to be not significant in EIA. Finally, we compare the significance determinations in proponent reports to final regulator decisions and determine that they are overwhelmingly identical (93-95%). Regulators are financially independent of proponents, but their decisions on significant are heavily dependent on the information and analysis provided by the proponent reports. As regulators rely on these reports, environmental impact assessments must be based on rigorous and transparent analysis.

RESUMEN

Earth is experiencing multiple global changes that will, together, determine the fate of many species. Yet, how biological communities respond to concurrent stressors at local-to-regional scales remains largely unknown. In particular, understanding how local habitat conversion interacts with regional climate change to shape patterns in ß-diversity-differences among sites in their species compositions-is critical to forecast communities in the Anthropocene. Here, we study patterns in bird ß-diversity across land-use and precipitation gradients in Costa Rica. We mapped forest cover, modeled regional precipitation, and collected data on bird community composition, vegetation structure, and tree diversity across 120 sites on 20 farms to answer three questions. First, do bird communities respond more strongly to changes in land use or climate in northwest Costa Rica? Second, does habitat conversion eliminate ß-diversity across climate gradients? Third, does regional climate control how communities respond to habitat conversion and, if so, how? After correcting for imperfect detection, we found that local land-use determined community shifts along the climate gradient. In forests, bird communities were distinct between sites that differed in vegetation structure or precipitation. In agriculture, however, vegetation structure was more uniform, contributing to 7%-11% less bird turnover than in forests. In addition, bird responses to agriculture and climate were linked: agricultural communities across the precipitation gradient shared more species with dry than wet forest communities. These findings suggest that habitat conversion and anticipated climate drying will act together to exacerbate biotic homogenization.

RESUMEN

Environmental assessment is the process that decision-makers rely on to predict, evaluate, and prevent biophysical, social, and economic impacts of potential project developments. The determination of significance in environmental assessment is central to environmental management in many nations. We reviewed ten recent environmental impact assessments from British Columbia, Canada and systematically reviewed and scored significance determination and the approaches used by assessors, the use of thresholds in significance determination, threshold exceedances, and the outcomes. Findings of significant impacts were exceedingly rare and practitioners used a combination of significance determination approaches, most commonly relying upon reasoned argumentation. Quantitative thresholds were rarely employed, with less than 10% of the valued components evaluated using thresholds. Even where quantitative thresholds for significance were exceeded, in every case practitioners used a variety of rationales to demote negative impacts to non-significance. These reasons include combinations of scale (temporal and spatial) of impacts, an already exceeded baseline, model uncertainty and/or substituting less stringent thresholds. Governments and agencies can better protect resources by requiring clear and defensible significance determinations, by making government-defined thresholds legally enforceable and accountable, and by requiring or encouraging significance determination through inclusive and collaborative approaches.

RESUMEN

We sought to take a first step toward better integration of social concerns into empirical ecosystem service (ES) work. We did this by adapting cognitive anthropological techniques to study the Clayoquot Sound social-ecological system on the Pacific coast of Canada's Vancouver Island. We used freelisting and ranking exercises to elicit how locals perceive ESs and to determine locals' preferred food species. We analyzed these data with the freelist-analysis software package ANTHROPAC. We considered the results in light of an ongoing trophic cascade caused by the government reintroduction of sea otters (Enhydra lutris) and their spread along the island's Pacific coast. We interviewed 67 local residents (n = 29 females, n = 38 males; n = 26 self-identified First Nation individuals, and n = 41 non-First Nation individuals) and 4 government managers responsible for conservation policy in the region. We found that the mental categories participants-including trained ecologists-used to think about ESs, did not match the standard academic ES typology. With reference to the latest ecological model projections for the region, we found that First Nations individuals and women were most likely to perceive the most immediate ES losses from the trophic cascade, with the most certainty. The inverse was found for men and non-First Nations individuals, generally. This suggests that 2 historically disadvantaged groups (i.e., First Nations and women) are poised to experience the immediate impacts of the government-initiated trophic cascade as yet another social injustice in a long line of perceived inequities. Left unaddressed, this could complicate efforts at multistakeholder ecosystem management in the region.

RESUMEN

Despite broad recognition of the value of social sciences and increasingly vocal calls for better engagement with the human element of conservation, the conservation social sciences remain misunderstood and underutilized in practice. The conservation social sciences can provide unique and important contributions to society's understanding of the relationships between humans and nature and to improving conservation practice and outcomes. There are 4 barriers-ideological, institutional, knowledge, and capacity-to meaningful integration of the social sciences into conservation. We provide practical guidance on overcoming these barriers to mainstream the social sciences in conservation science, practice, and policy. Broadly, we recommend fostering knowledge on the scope and contributions of the social sciences to conservation, including social scientists from the inception of interdisciplinary research projects, incorporating social science research and insights during all stages of conservation planning and implementation, building social science capacity at all scales in conservation organizations and agencies, and promoting engagement with the social sciences in and through global conservation policy-influencing organizations. Conservation social scientists, too, need to be willing to engage with natural science knowledge and to communicate insights and recommendations clearly. We urge the conservation community to move beyond superficial engagement with the conservation social sciences. A more inclusive and integrative conservation science-one that includes the natural and social sciences-will enable more ecologically effective and socially just conservation. Better collaboration among social scientists, natural scientists, practitioners, and policy makers will facilitate a renewed and more robust conservation. Mainstreaming the conservation social sciences will facilitate the uptake of the full range of insights and contributions from these fields into conservation policy and practice.

RESUMEN

Coastal environments are some of the most populated on Earth, with greater pressures projected in the future. Managing coastal systems requires the consideration of multiple uses, which both benefit from and threaten multiple ecosystem services. Thus understanding the cumulative impacts of human activities on coastal ecosystem services would seem fundamental to management, yet there is no widely accepted approach for assessing these. This study trials an approach for understanding the cumulative impacts of anthropogenic change, focusing on Tasman and Golden Bays, New Zealand. Using an expert elicitation procedure, we collected information on three aspects of cumulative impacts: the importance and magnitude of impacts by various activities and stressors on ecosystem services, and the causal processes of impact on ecosystem services. We assessed impacts to four ecosystem service benefits - fisheries, shellfish aquaculture, marine recreation and existence value of biodiversity-addressing three main research questions: (1) how severe are cumulative impacts on ecosystem services (correspondingly, what potential is there for restoration)?; (2) are threats evenly distributed across activities and stressors, or do a few threats dominate?; (3) do prominent activities mainly operate through direct stressors, or do they often exacerbate other impacts? We found (1) that despite high uncertainty in the threat posed by individual stressors and impacts, total cumulative impact is consistently severe for all four ecosystem services. (2) A subset of drivers and stressors pose important threats across the ecosystem services explored, including climate change, commercial fishing, sedimentation and pollution. (3) Climate change and commercial fishing contribute to prominent indirect impacts across ecosystem services by exacerbating regional impacts, namely sedimentation and pollution. The prevalence and magnitude of these indirect, networked impacts highlights the need for approaches like this to understand mechanisms of impact, in order to develop strategies to manage them.

RESUMEN

Agroforestry management in smallholder agriculture can provide climate change mitigation and adaptation benefits and has been promoted as 'climate-smart agriculture' (CSA), yet has generally been left out of international and voluntary carbon (C) mitigation agreements. A key reason for this omission is the cost and uncertainty of monitoring C at the farm scale in heterogeneous smallholder landscapes. A largely overlooked alternative is to monitor C at more aggregated scales and develop C contracts with groups of land owners, community organizations or C aggregators working across entire landscapes (e.g., watersheds, communities, municipalities, etc.). In this study we use a 100-km2 agricultural area in El Salvador to demonstrate how high-spatial resolution optical satellite imagery can be used to map aboveground woody biomass (AGWB) C at the landscape scale with very low uncertainty (95% probability of a deviation of less than 1%). Uncertainty of AGWB-C estimates remained low (<5%) for areas as small as 250 ha, despite high uncertainties at the farm and plot scale (34-99%). We estimate that CSA adoption could more than double AGWB-C stocks on agricultural lands in the study area, and that utilizing AGWB-C maps to target denuded areas could increase C gains per unit area by 46%. The potential value of C credits under a plausible adoption scenario would range from $38,270 to $354,000 yr-1 for the study area, or about $13 to $124 ha-1 yr-1, depending on C prices. Considering farm sizes in smallholder landscapes rarely exceed 1-2 ha, relying solely on direct C payments to farmers may not lead to widespread CSA adoption, especially if farm-scale monitoring is required. Instead, landscape-scale approaches to C contracting, supported by satellite-based monitoring methods such as ours, could be a key strategy to reduce costs and uncertainty of C monitoring in heterogeneous smallholder landscapes, thereby incentivizing more widespread CSA adoption.

RESUMEN

Stakeholders' nonmaterial desires, needs, and values often critically influence the success of conservation projects. These considerations are challenging to articulate and characterize, resulting in their limited uptake in management and policy. We devised an interview protocol designed to enhance understanding of cultural ecosystem services (CES). The protocol begins with discussion of ecosystem-related activities (e.g., recreation, hunting) and management and then addresses CES, prompting for values encompassing concepts identified in the Millennium Ecosystem Assessment (2005) and explored in other CES research. We piloted the protocol in Hawaii and British Columbia. In each location, we interviewed 30 individuals from diverse backgrounds. We analyzed results from the 2 locations to determine the effectiveness of the interview protocol in elucidating nonmaterial values. The qualitative and spatial components of the protocol helped characterize cultural, social, and ethical values associated with ecosystems in multiple ways. Maps and situational, or vignette-like, questions helped respondents articulate difficult-to-discuss values. Open-ended prompts allowed respondents to express a diversity of ecosystem-related values and proved sufficiently flexible for interviewees to communicate values for which the protocol did not explicitly probe. Finally, the results suggest that certain values, those mentioned frequently throughout the interview, are particularly salient for particular populations. The protocol can provide efficient, contextual, and place-based data on the importance of particular ecosystem attributes for human well-being. Qualitative data are complementary to quantitative and spatial assessments in the comprehensive representation of people's values pertaining to ecosystems, and this protocol may assist in incorporating values frequently overlooked in decision making processes.

RESUMEN

Cultural ecosystem services (ES) are consistently recognized but not yet adequately defined or integrated within the ES framework. A substantial body of models, methods, and data relevant to cultural services has been developed within the social and behavioral sciences before and outside of the ES approach. A selective review of work in landscape aesthetics, cultural heritage, outdoor recreation, and spiritual significance demonstrates opportunities for operationally defining cultural services in terms of socioecological models, consistent with the larger set of ES. Such models explicitly link ecological structures and functions with cultural values and benefits, facilitating communication between scientists and stakeholders and enabling economic, multicriterion, deliberative evaluation and other methods that can clarify tradeoffs and synergies involving cultural ES. Based on this approach, a common representation is offered that frames cultural services, along with all ES, by the relative contribution of relevant ecological structures and functions and by applicable social evaluation approaches. This perspective provides a foundation for merging ecological and social science epistemologies to define and integrate cultural services better within the broader ES framework.

RESUMEN

The ecosystem services concept is used to make explicit the diverse benefits ecosystems provide to people, with the goal of improving assessment and, ultimately, decision-making. Alongside material benefits such as natural resources (e.g., clean water, timber), this concept includes-through the 'cultural' category of ecosystem services-diverse non-material benefits that people obtain through interactions with ecosystems (e.g., spiritual inspiration, cultural identity, recreation). Despite the longstanding focus of ecosystem services research on measurement, most cultural ecosystem services have defined measurement and inclusion alongside other more 'material' services. This gap in measurement of cultural ecosystem services is a product of several perceived problems, some of which are not real problems and some of which can be mitigated or even solved without undue difficulty. Because of the fractured nature of the literature, these problems continue to plague the discussion of cultural services. In this paper we discuss several such problems, which although they have been addressed singly, have not been brought together in a single discussion. There is a need for a single, accessible treatment of the importance and feasibility of integrating cultural ecosystem services alongside others.

RESUMEN

The demand for better representation of cultural considerations in environmental management is increasingly evident. As two cases in point, ecosystem service approaches increasingly include cultural services, and resource planners recognize indigenous constituents and the cultural knowledge they hold as key to good environmental management. Accordingly, collaborations between anthropologists, planners, decision makers and biodiversity experts about the subject of culture are increasingly common-but also commonly fraught. Those whose expertise is culture often engage in such collaborations because they worry a practitioner from 'elsewhere' will employ a 'measure of culture' that is poorly or naively conceived. Those from an economic or biophysical training must grapple with the intangible properties of culture as they intersect with economic, biological or other material measures. This paper seeks to assist those who engage in collaborations to characterize cultural benefits or impacts relevant to decision-making in three ways; by: (i) considering the likely mindset of would-be collaborators; (ii) providing examples of tested approaches that might enable innovation; and (iii) characterizing the kinds of obstacles that are in principle solvable through methodological alternatives. We accomplish these tasks in part by examining three cases wherein culture was a critical variable in environmental decision making: risk management in New Zealand associated with Maori concerns about genetically modified organisms; cultural services to assist marine planning in coastal British Columbia; and a decision-making process involving a local First Nation about water flows in a regulated river in western Canada. We examine how 'culture' came to be manifest in each case, drawing from ethnographic and cultural-models interviews and using subjective metrics (recommended by theories of judgment and decision making) to express cultural concerns. We conclude that the characterization of cultural benefits and impacts is least amenable to methodological solution when prevailing cultural worldviews contain elements fundamentally at odds with efforts to quantify benefits/impacts, but that even in such cases some improvements are achievable if decision-makers are flexible regarding processes for consultation with community members and how quantification is structured.

RESUMEN

Fisheries are important sources of nutrients for people, but fisheries science and management do not consider nutrient information. The result is that fisheries are conducted without knowledge of how exploited species portfolios produce nutrients, how these yields have changed over time, and how they may change in the future. Here, we develop approaches for nutrient-informed analysis, and illustrate their use by applying them to catches from northwest Atlantic fisheries from 1950 to 2014. Relative to catch weights, nutrient yields showed more change over time and greater degrees of concentration in fewer taxa. Species that were minor from a weight perspective were identified as key sources of specific nutrients. Atlantic herring (Clupea harengus) emerge as a cornerstone of regional nutrient yields, with recent yields of some nutrients so disproportionately reliant upon herring as to indicate a potential lack of resilience. Insights such as these emphasize the need for nutrient informed approaches to fisheries assessment.

RESUMEN

Mainstreaming of ecosystem service approaches has been proposed as one path toward sustainable development. Meanwhile, critics of ecosystem services question if the approach can account for the multiple values of ecosystems to diverse groups of people, or for aspects of inter- and intra-generational justice. In particular, an ecosystem service approach often overlooks power dimensions and capabilities that are core to environmental justice. This article addresses the need for greater guidance on incorporating justice into ecosystem services research and practice. We point to the importance of deep engagement with stakeholders and rights holders to disentangle contextual factors that moderate justice outcomes on ecosystem service attribution and appropriation in socio-political interventions. Such a holistic perspective enables the integration of values and knowledge plurality for enhancing justice in ecosystem services research. This broadened perspective paves a way for transformative ecosystem service assessments, management, and research, which can help inform and design governance structures that nourish human agency to sustainably identify, manage, and enjoy ecosystem services for human wellbeing.

RESUMEN

To achieve a sustainable future, it is imperative to transform human actions collectively and underlying social structures. Decades of research in social sciences have offered complementary insights into how such transformations might occur. However, these insights largely remain disjunct and of limited scope, such that strategies for solving global environmental challenges remain elusive. There is a need to integrate approaches focusing on individuals and social structures to understand how individual actions influence and are in turn influenced by social structures and norms. In this paper, we synthesize a range of insights across different schools of thought and integrate them in a novel framework for transformative social change. Our framework explains the relationships among individual behaviors, collective actions, and social structures and helps change agents guide societal transitions toward environmental sustainability. We apply this framework to the global wildlife trade-which presents several distinct challenges of human actions, especially amidst the Covid-19 pandemic-and identify pathways toward transformative change. One key distinction we make is between different individual actions that comprise the practice itself (e.g., buying wildlife products; private action) and those that push for a broader system change in practice (e.g., signaling (dis)approval for wildlife consumption; social-signaling action, and campaigning for policies that end unsustainable wildlife trade; system-changing action). In general, transformative change will require an integrative approach that includes both structural reforms and all three classes of individual action.

RESUMEN

The future of biodiversity and ecosystem services hinges on harmonizing agricultural production and conservation, yet there is no planning algorithm for predicting the efficacy of conservation investments in farmland. We present a conservation planning framework for countryside (working agricultural landscapes) that calculates the production and conservation benefits to the current baseline of incremental investments. Our framework is analogous to the use of reserve design algorithms. Unlike much countryside modeling, our framework is designed for application in data-limited contexts, which are prevalent. We apply our framework to quantify the payoff for Costa Rican birds of changing farm plot and border vegetation. We show that installing windbreaks of native vegetation enhances both bird diversity and farm income, especially when complementing certain crop types. We make predictions that differ from those of approaches currently applied to agri-environment planning,: e.g., although habitat with trees has lower local species richness than farm plot habitats (1-44% lower), replacing any plot habitat with trees should boost regional richness considerably. Our planning framework reveals the small, targeted changes on farms that can make big differences for biodiversity.

RESUMEN

Ecosystem services are impacted through restricting service supply, through limiting people from accessing services, and by affecting the quality of services. We map cumulative impacts to 8 different ecosystem services in coastal British Columbia using InVEST models, spatial data, and expert elicitation to quantify risk to each service from anthropogenic activities. We find that impact to service access and quality as well as impact to service supply results in greater severity of impact and a greater diversity of causal processes of impact than only considering impact to service supply. This suggests that limiting access to services and impacts to service quality may be important and understanding these kinds of impacts may complement our knowledge of impacts to biophysical systems that produce services. Some ecosystem services are at greater risk from climate stressors while others face greater risk from local activities. Prominent causal pathways of impact include limiting access and affecting quality. Mapping cumulative impacts to ecosystem services can yield rich insights, including highlighting areas of high impact and understanding causes of impact, and should be an essential management tool to help maintain the flow of services we benefit from.
