Making management decisions for conservation of imperiled species requires consideration of both social and ecological factors related to the decision context. In this dissertation, I developed tools to help support conservation decision making for two imperiled fishes – Robust Redhorse (Moxostoma robustum) and Sicklefin Redhorse (Moxostoma sp.) – in the southeastern U.S. Chapter 1 introduces the context of the studies and sets up the dissertation structure. In Chapter 2, I constructed a population estimation model to help inform managers of the population status and key parameters of Sicklefin Redhorse in Brasstown Creek, GA. The model analyzed data collected by two different sampling methods – fyke nets and PIT antenna, thereby helping demonstrate the efficacy and trade-offs of using the different sampling methods. In Chapter 3, I worked with members of the Robust Redhorse Conservation Committee to go through a structured decision-making process involving facilitated workshops, population estimation modeling, and population viability analysis to help stakeholders evaluate the probability of potential management scenarios achieving management objectives. The process used in Chapter 3 and results from the management evaluation could help the RRCC develop an adaptive management framework for conserving the species in the long-term. Learning is an important aspect of species conservation and management. In Chapter 4, I used the Robust Redhorse Conservation Committee as a case study to investigate how a diverse group of stakeholders can learn together through collaboration and deliberation (i.e., social learning). Through analysis of documents and interviews, I identified learning outcomes from the RRCC, including gaining knowledge about the species and ecosystem being managed (instrumental learning), and relationship and trust building (relational learning). I also identified several factors affecting social learning among RRCC members, such as diversity of the stakeholder group, quality and frequency of stakeholder interactions, and quality of information exchange and deliberations. Chapter 5 offers summaries of key findings from Chapters 2–4 and my reflections on conducting integrative conservation research.
