This document outlines a prioritization protocol for optimally allocating conservation resources among threatened species. It describes a 9-step process to (1) define conservation objectives, (2) list biodiversity assets, (3) weight the assets based on various criteria, (4) list potential management projects, (5) calculate costs, (6) predict benefits, (7) estimate likelihood of success, (8) consider constraints, and (9) rank projects to choose the optimal set that maximizes threatened species protection given limited resources. It also references an online prioritization tool used by the Idaho Department of Fish and Game to implement this protocol.
