Long-term Risks to Marbled Murrelet (Brachyramphus Marmoratus) Populations

📖 The Scoop

This report analyzes the conservation risk, or the confidence of success, associated with nesting habitat management strategies for the marbled murrelet in British Columbia. The framework for the analysis was a habitat-linked population viability analysis using an integrated package of models of marbled murrelet demography, habitat associations, habitat management, and environmental change to project relative population size & persistence probability at various forest management assumptions. The analysis focusses on changes in persistence probability as an unambiguous measure of risk, applied primarily at the scale of the marbled murrelet conservation regions proposed by the Canadian Marbled Murrelet Recovery Team. The report also assesses coast-wide risk using a bet hedging probability theory approach to combining regional risks. A key component of the analysis was the inclusion of uncertainty and how robust different management strategies might be in light of those uncertainties. Bayesian decision analysis was applied to determine the optimal choice of habitat amount to set aside. Appendices include details of the models used in the analysis.
