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 willfacilitate the uptake of the full range of insights and contributions from these fields into conservation policy and practice. A pesar del reconocimiento general del valor de las ciencias sociales y los crecientes llamados por un mejor compromiso con el elemento humano de la conservación, las ciencias sociales de la conservación siguen siendo malentendidas y poco utilizadas en la práctica. Las ciencias sociales de la conservación pueden proporcionar contribuciones únicas e importantes para el entendimiento de la sociedad de las relaciones entre los humanos y la naturaleza y para la mejora de las prácticas de la conservación y sus resultados. Existen cuatro barreras - ideológicas, institucionales, de conocimiento y de capacidad - para la integración significativa de las ciencias sociales dentro de la conservación. Proporcionamos una guia práctica sobre cómo sobreponerse a estas barreras paraJncorporar la perspectiva de las ciencias sociales a la ciencia, las prácticas y las políticas de conservación. En general, recomendamos promover el conocimiento sobre el alcance y las contribuciones de las ciencias sociales para la conservación, incluir a los científicos sociales desde el origen de los proyectos de investigación interdisciplinaria, incorporar la investigación de las ciencias sociales y las percepciones durante todas las fases de la planificación y la implementación de la conservación, construir la capacidad de las ciencias sociales en todas las escalas de las organizaciones y agencias de conservación y promover el compromiso con las ciencias sociales en y a través de organizaciones de conservación con influencia política. Los científicos sociales de la conservación, también, necesitan estar dispuestos a involucrarse con el conocimiento de las ciencias naturales y a comunicar percepciones y recomendaciones de manera clara. Le urgimos a la comunidad de la conservación que vaya más allá del compromiso superficial con las ciencias sociales de la conservación. Una ciencia de la conservación más incluyente y integradora - una que incluya a las ciencias sociales y naturales - permitirá una conservación más justa socialmente y más efectiva ecológicamente. Una mejor colaboración entre los científicos sociales, los científicos naturales, los practicantes y quienes elaboran las políticas facilitará una conservación más renovada y más sólida. Incorporar la perspectiva de las ciencias sociales de la conservación facilitará la absorción de la extensión completa de conocimiento y contribuciones de estos campos a la práctica y las políticas de la conservación.

A vast number of prioritization schemes have been developed to help conservation navigate tough decisions about the allocation of finite resources. However, the application of quantitative approaches to setting priorities in conservation frequently includes mistakes that can undermine their authors' intention to be more rigorous and scientific in the way priorities are established and resources allocated. Drawing on well-established principles of decision science, we highlight 6 mistakes commonly associated with setting priorities for conservation: not acknowledging conservation plans are prioritizations; trying to solve an illdefined problem; not prioritizing actions; arbitrariness; hidden value judgments; and not acknowledging risk of failure. We explain these mistakes and offer a path to help conservation planners avoid making the same mistakes in future prioritizations. Se ha desarrollado un vasto número de esquemas de priorización para ayudar a que la conservación navegue entre decisiones difíciles en cuanto a la asignación de recursos finitos. Sin embargo, la aplicación de métodos cuantitativos para la definición de prioridades en la conservación frecuentemente incluye errores que pueden socavar la intención de sus autores de ser más rigurosos y científicos en la manera en que se establecen las prioridades y se asignan los recursos. Con base en los bien establecidos principios de la ciencia de la decisión, resaltamos seis errores comúnmente asociados con la definición de prioridades para la conservación: no reconocer que los planes de conservación son priorizaciones; tratar de resolver un problema mal definido; no priorizar acciones; arbitrariedad; juicios de valor ocultos y no reconocer el riesgo de fracasar. Explicamos estos errores y ofrecemos un camino para que planificadores de la conservación no cometan los mismos errores en priorizaciones futuras.

Species interactions matter to conservation. Setting an ambitious recovery target for a species requires considering the size, density and demographic structure of its populations such that they fulfill the interactions, roles and functions of the species in the ecosystems in which they are embedded. A recently proposed framework for an IUCN Green List of Species formalizes this requirement by defining a fully recovered species in terms of representation, viability and functionality. Defining and quantifying ecological function from the viewpoint of species recovery is challenging, both in concept and application, but also an opportunity to insert ecological theory into conservation practice. We propose two complementary approaches to assessing a species’ ecological functions: a confirmation approach that starts with a list of the interactions of the species, identifying the ecological processes and the other species that are involved in these interactions, and quantifying the extent to which the species contributes to the identified ecological process; and an elimination approach that infers functionality by ruling out symptoms of reduced functionality, analogous to the Red List approach that focuses on symptoms of reduced viability. Despite the challenges, we believe that incorporation of functionality into species recovery planning is possible in most cases. It is also an essential element of an aspirational conservation vision that goes beyond preventing extinctions, aiming to restore a species to levels beyond what is required only for its own viability. This vision focuses on conservation and recovery at the species level, but also sees species as embedded in ecosystems, influencing and being influenced by the processes in those ecosystems. Thus, it connects and integrates conservation at the species and ecosystem levels.

The need to adapt to climate change has become increasingly apparent, and many believe the practice of biodiversity conservation will need to alter to face this challenge. Conservation organizations are eager to determine how they should adapt their practices to climate change. This involves asking the fundamental question of what adaptation to climate change means. Most studies on climate change and conservation, if they consider adaptation at all, assume it is equivalent to the ability of species to adapt naturally to climate change as stated in Article 2 of the United Nations Framework Convention on Climate Change. Adaptation, however, can refer to an array of activities that range from natural adaptation, at one end of the spectrum, to sustainability science in coupled human and natural systems at the other. Most conservation organizations deal with complex systems in which adaptation to climate change involves making decisions on priorities for biodiversity conservation in the face of dynamic risks and involving the public in these decisions. Discursive methods such as analytic deliberation are useful for integrating scientific knowledge with public perceptions and values, particularly when large uncertainties and risks are involved. The use of scenarios in conservation planning is a useful way to build shared understanding at the science-policy interface. Similarly, boundary organizations--organizations or institutions that bridge different scales or mediate the relationship between science and policy--could prove useful for managing the transdisciplinary nature of adaptation to climate change, providing communication and brokerage services and helping to build adaptive capacity. The fact that some nongovernmental organizations (NGOs) are active across the areas of science, policy, and practice makes them well placed to fulfill this role in integrated assessments of biodiversity conservation and adaptation to climate change.

Many of the challenges conservation professionals face can be framed as scale mismatches. The problem of scale mismatch occurs when the planning for and implementation of conservation actions is at a scale that does not reflect the scale of the conservation problem. The challenges in conservation planning related to scale mismatch include ecosystem or ecological process transcendence of governance boundaries; limited availability of fine-resolution data; lack of operational capacity for implementation; lack of understanding of social-ecological system components; threats to ecological diversity that operate at diverse spatial and temporal scales; mismatch between funding and the long-term nature of ecological processes; rate of action implementation that does not reflect the rate of change of the ecological system; lack of appropriate indicators for monitoring activities; and occurrence of ecological change at scales smaller or larger than the scale of implementation or monitoring. Not recognizing and accounting for these challenges when planning for conservation can result in actions that do not address the multiscale nature of conservation problems and that do not achieve conservation objectives. Social networks link organizations and individuals across space and time and determine the scale of conservation actions; thus, an understanding of the social networks associated with conservation planning will help determine the potential for implementing conservation actions at the required scales. Social-network analyses can be used to explore whether these networks constrain or enable key social processes and how multiple scales of action are linked. Results of network analyses can be used to mitigate scale mismatches in assessing, planning, implementing, and monitoring conservation projects. Muchos de los retos que enfrentan los profesionales de la conservación pueden ser catalogados como discordancia de escalas. El problema de discordancia de escalas ocurre cuando la planificación e implementación de acciones de conservación se llevan a cabo en una escala que no refleja la escala del problema de conservación. Los retos de la planificación de la conservación relacionados con la discordancia de escala incluyen el rebase de límites de gobernanza por los procesos ecológicos; la disponibilidad limitada de datos de resolución fina; la carencia de capacidad operativa para la implementación; la falta de entendimiento de los componentes socio-ecológicos del sistema; amenazas a la diversidad ecológica que operan en escalas espaciales y temporales diversas; discordancia entre el financiamiento y la naturaleza a largo plazo de los procesos ecológicos; tasa de implementación de acciones que no refleja la tasa de cambio del sistema ecológico; ausencia de indicadores apropiados de las actividades de monitoreo y ocurrencia de cambio ecológico en escalas menores o mayores que la escala de implementación o monitoreo. El no reconocimiento y consideración de estos retos al planificar la conservación puede resultar en acciones que no abordan la naturaleza multiescala de los problemas de conservación y que no se alcancen los objetivos de conservación. Las redes sociales enlazan organizaciones e individuos en el tiempo y espacio y determinan la escala de las acciones de conservación; por lo tanto, el entendimiento de las redes sociales asociadas con la planificación de la conservación ayudará a determinar el potencial para la implementación de acciones de conservación en las escalas requeridas. El análisis de redes sociales puede ser utilizado para explorar si esas redes constriñen o facilitan procesos sociales claves y como se relacionan las múltiples escalas de acción. Los resultados del análisis de redes pueden ser utilizados para mitigar la discordancia de escalas en la evaluación, planificación, implementación y monitoreo de proyectos de conservación.

To conserve ecological connectivity (the ability to support animal movement, gene flow, range shifts, and other ecological and evolutionary processes that require large areas), conservation professionals need coarse-grained maps to serve as decision-support tools or vision statements and fine-grained maps to prescribe site-specific interventions. To date, research has focused primarily on fine-grained maps (linkage designs) covering small areas. In contrast, we devised 7 steps to coarsely map dozens to hundreds of linkages over a large area, such as a nation, province, or ecoregion. We provide recommendations on how to perform each step on the basis of our experiences with 6 projects: California Missing Linkages (2001), Arizona Wildlife Linkage Assessment (2006), California Essential Habitat Connectivity (2010), Two Countries, One Forest (northeastern United States and southeastern Canada) (2010), Washington State Connected Landscapes (2010), and the Bhutan Biological Corridor Complex (2010). The 2 most difficult steps are mapping natural landscape blocks (areas whose conservation value derives from the species and ecological processes within them) and determining which pairs of blocks can feasibly be connected in a way that promotes conservation.Decision rules for mapping natural landscape blocks and determining which pairs of blocks to connect must reflect not only technical criteria, but also the values and priorities of stakeholders. We recommend blocks be mapped on the basis of a combination of naturalness, protection status, linear barriers, and habitat quality for selected species. We describe manual and automated procedures to identify currently functioning or restorable linkages. Once pairs of blocks have been identified, linkage polygons can be mapped by least-cost modeling, other approaches from graph theory, or individual-based movement models. The approaches we outline make assumptions explicit, have outputs that can be improved as underlying data are improved, and help implementers focus strictly on ecological connectivity. Para conservar la conectividad ecologica (la habilidad para soportar movimiento de animales, flujo de genes, cambios de rango de distribucion y otros procesos ecológicos y evolutivos que requieren áreas extensas), los profesionales de la conservación necesitan mapas de grano grueso que sirvan como herramientas de soporte para la toma de decisiones y mapas de grano fino para recomendar intervenciones en sitios especificos. A la fecha, la investigación se ha centrado principalmente en mapas de grano fino (diseño de conexiones) que abarcan areas pequeüas. En contraste, diseüamos 7 pasos para hacer mapas de grano grueso de docenas hasta centenas de conexiones en un área extensa, como un pais, provincia ecorregión. Proporcionamos recomendaciones de cómo llevar a cabo cada paso con base en nuestrasexperiencias con oproyectos: Conexiones Faltantes en California (2001), Evaluatión de la Conexión de Vida Silvestre en Arizona (2006), Conectividad de Hábitat Esencial de California (2010), Dos Paises-Un Bosque (noreste de Estados Unidos y sureste de Canadá) (2010), Paisajes Conectados del Estado de Washington (2010), y el Complejo del Corredor Biologico de Bután (2010). Los dos pasos mas difidles son el mapeo de los bloques de paisaje natural (áreas donde el valor de conservatión se dériva de las especies y sus procesos ecológicos) y la déterminatión de los pares de bloques que son factibles de conectarse de manera que promueva la conservatión. Las réglas de decisión para el mapeo de bloques de paisaje natural y la déterminatión de cuales pares de bloques sern conectados debe reflejar no solo criterios técnicos, sino también los valores yprioridades de los actores involucrados. Recomendamos que los bloques sean mapeados con base en una combination de naturalidad, estatus de protection, barreras lineales, y calidad del habitat para especies selectas. Describimos procedimientos manualesy automatizados para identificar las conexiones restaurables ofuncionales actualmente. Una vez que los pares de bloques han sido identificados, lospoligonos de conexion pueden ser mapeados por modelaje de costo minimo, otros métodos de teoria dégrafas modelos de movimiento basados en individuos. Los métodos que delineamos hacen suposiciones explicitas, tienen resultados que pueden ser mejorados a medida que mejoran los datos subyacentes y ayudan a que los implementadores se concentren estrictamente en la conectividad ecologica.

Conservation assessment is a rapidly evolving discipline whose stated goal is the design of networks of protected areas that represent and ensure the persistence of nature (i.e., species, habitats, and environmental processes) by separating priority areas from the activities that degrade or destroy them. Nevertheless, despite a burgeoning scientific literature that ever refines these techniques for allocating conservation resources, it is widely believed that conservation assessments are rarely translated into actions that actually conserve nature. We reviewed the conservation assessment literature in peer-reviewed journals and conducted survey questionnaires of the authors of these studies. Two-thirds of conservation assessments published in the peer-reviewed scientific literature do not deliver conservation action, primarily because most researchers never plan for implementation. This research-implementation gap between conservation science and real-world action is a genuine phenomenon and is a specific example of the \"knowing-doing gap\" that is widely recognized in management science. Given the woefully inadequate resources allocated for conservation, our findings raise questions over the utility of conservation assessment science, as currently practiced, to provide useful, pragmatic solutions to conservation planning problems. A reevaluation of the conceptual and operational basis of conservation planning research is urgently required. We recommend the following actions for beginning a process for bridging the research-implementation gap in conservation planning: (1) acknowledge the research-implementation gap is real, (2) source research questions from practitioners, (3) situate research within a broader conservation planning model, (4) expand the social dimension of conservation assessments, (5) support conservation plans with transdisciplinary social learning institutions, (6) reward academics for societal engagement and implementation, and (7) train students in skills for \"doing\" conservation.

The concept of metacommunity (i.e., a set of local communities linked by dispersal) has gained great popularity among community ecologists. However, metacommunity research mostly addresses questions on spatial patterns of biodiversity at the regional scale, whereas conservation planning requires quantifying temporal variation in those metacommunities and the contributions that individual (local) sites make to regional dynamics. We propose that recent advances in diversity-partitioning methods may allow for a better understanding of metacommunity dynamics and the identification of keystone sites. We used time series of the 2 components of beta diversity (richness and replacement) and the contributions of local sites to these components to examine which sites controlled source-sink dynamics in a highly dynamic model system (an intermittent river). The relative importance of the richness and replacement components of beta diversity fluctuated over time, and sample aggregation led to underestimation of beta diversity by up to 35%. Our literature review revealed that research on intermittent rivers would benefit greatly from examination of beta-diversity components over time. Adequately appraising spatiotemporal variability in community composition and identifying sites that are pivotal for maintaining biodiversity at the landscape scale are key needs for conservation prioritization and planning. Thus, our framework may be used to guide conservation actions in highly dynamic ecosystems when time-series data describing biodiversity across sites connected by dispersal are available.

Conservation funds are grossly inadequate to address the plight of threatened species. Government and conservation organizations faced with the task of conserving threatened species desperately need simple strategies for allocating limited resources. The academic literature dedicated to systematic priority setting usually recommends ranking species on several criteria, including level of endangerment and metrics of species value such as evolutionary distinctiveness, ecological importance, and social significance. These approaches ignore 2 crucial factors: the cost of management and the likelihood that the management will succeed. These oversights will result in misallocation of scarce conservation resources and possibly unnecessary losses. We devised a project prioritization protocol (PPP) to optimize resource allocation among New Zealand's threatened-species projects, where costs, benefits (including species values), and the likelihood of management success were considered simultaneously. We compared the number of species managed and the expected benefits gained with 5 prioritization criteria: PPP with weightings based on species value; PPP with species weighted equally; management costs; species value; and threat status. We found that the rational use of cost and success information substantially increased the number of species managed, and prioritizing management projects according to species value or threat status in isolation was inefficient and resulted in fewer species managed. In addition, we found a clear trade-off between funding management of a greater number of the most cost-efficient and least risky projects and funding fewer projects to manage the species of higher value. Specifically, 11 of 32 species projects could be funded if projects were weighted by species value compared with 16 projects if projects were not weighted. This highlights the value of a transparent decision-making process, which enables a careful consideration of trade-offs. The use of PPP can substantially improve conservation outcomes for threatened species by increasing efficiency and ensuring transparency of management decisions.

Spatial prioritization techniques are applied in conservation-planning initiatives to allocate conservation resources. Although typically they are based on ecological data (e.g., species, habitats, ecological processes), increasingly they also include nonecological data, mostly on the vulnerability of valued features and economic costs of implementation. Nevertheless, the effectiveness of conservation actions implemented through conservation-planning initiatives is a function of the human and social dimensions of social-ecological systems, such as stakeholders' willingness and capacity to participate. We assessed human and social factors hypothesized to define opportunities for implementing effective conservation action by individual land managers (those responsible for making day-to-day decisions on land use) and mapped these to schedule implementation of a private land conservation program. We surveyed 48 land managers who owned 301 land parcels in the Makana Municipality of the Eastern Cape province in South Africa. Psychometric statistical and cluster analyses were applied to the interview data so as to map human and social factors of conservation opportunity across a landscape of regional conservation importance. Four groups of landowners were identified, in rank order, for a phased implementation process. Furthermore, using psychometric statistical techniques, we reduced the number of interview questions from 165 to 45, which is a preliminary step toward developing surrogates for human and social factors that can be developed rapidly and complemented with measures of conservation value, vulnerability, and economic cost to more-effectively schedule conservation actions. This work provides conservation and land management professionals direction on where and how implementation of local-scale conservation should be undertaken to ensure it is feasible.
