Abstract
The impacts of climate change and human activities on the landscape threaten biodiversity as well as ecosystem services worldwide. Efforts to pursue more sustainable environmental management are hindered by scientific uncertainty, the unpredictability of social and ecological responses to change, and the dependence of conservation success on coordinated actions across governmental jurisdictions and boundaries of land ownership. To coordinate actions across landscapes with the flexibility to address complexity and uncertainty, environmental decision-making can aim to manage ecological resilience rather than optimizing actions for a specific resource, as has historically been the norm in natural resources management. Ecological resilience is the ability of an ecosystem to cope with shocks and continue functioning without crossing a threshold that changes its identity. Yet, in many settings, cross-scale ecological knowledge is not provided in a manner that effectively informs policy to promote coordinated actions at relevant spatial and temporal scales to manage resilience.
Riverine ecosystems exemplify this problem with biophysical processes and flows that change rapidly, span political and property boundaries, and depend on three-dimensional connectivity. Restoring and maintaining the multidimensional connectivity that sustains ecosystem services requires adaptive policy processes to coordinate riverine land management practices along river networks. This dissertation presents new approaches to harness untapped capacity to link actions across boundaries by intersecting riverine ecological understanding with existing laws and policies.
Contrasting perspectives embedded in connectivity conservation issues at the social-ecological interface are addressed in each chapter. Chapter One presents a science-based policy process with a social-ecological categorization scheme to clarify the role of science in fostering policy to coordinate conservation actions across scales and heterogeneous landscapes. Chapter Two presents a novel methodology for identifying place-based opportunities to coordinate corridor conservation across boundaries by mapping and quantifying existing legal capacity. Chapter Three presents a strategy for cloud-based environmental monitoring to increase the timeliness and relevance of remote sensing data in providing feedback for adaptive management and policy evaluation. The findings contribute to the exchange of information across the science-policy interface to facilitate coordination across scales and lay out future steps for transdisciplinary research to address barriers to managing ecological resilience.
