The control of invasive, non-native plants is of increasing concern in ecosystem management as invasive
plant species are found to be threatening natural resources through the disruption of biodiversity, habitat
structure, and ecosystem processes across the world. State Government leadership in invasive plant
management policy is required to ensure efforts are coordinated and cost effective. As resources for
managing invasive plants are limited, the need to evaluate and rank non-native species is a primary
concern before expensive management is attempted so that the most threatening species may be addressed
An objective, repeatable and clearly defined methodology for prioritizing invasive plant management
within Department of Natural Resources, Division of Agriculture (DOA) was developed. The
development process reviewed literature on the philosophy of decision analysis and various case studies
in its application to natural resource projects and act as a guide for the development of an initial process
framework. Subject matter experts were engaged to develop the decision criteria using a Delphi survey
technique to collect information on experts’ current priorities and tolerances for invasive plants. The final
product includes a process diagram, a summary worksheet, and a detailed record of the evaluation
decision, rationale, and supporting resources.
