Structured decision-making to develop decision analysis tools for Plains Topminnow (Fundulus sciadicus) management in Nebraska.

Abstract

Decision making in conservation planning requires recognition of ecological, social, and political perspectives and the economics of management strategies. Through the process of structured decision-making, stakeholders can provide expertise, and beliefs are used for deliberation of important ecological and population processes and uncertainties to identify management strategies most likely to achieve agency and stakeholder desires. The Nebraska Games and Parks Commission (NGPC) recognized implementing structured decision making was needed for Plains Topminnow (Fundulus sciadicus, PTM), a prioritized species for management lacking an organized management plan in Nebraska. In collaboration with NGPC, we have designed decision analysis tools to aid in managing PTM in Nebraska. Two models have been developed to the α-level with a Bayesian belief network to target management and a Bayesian decision network to rank management actions at stream sites. I have outlined further sensitivity analysis and recommendations for alterations needed to complete these modeling efforts. Through this approach, a standardized, non-regulatory management plan can be used to conserve PTM in Nebraska through defensible management decisions.
