Abstract

Formulating effective management plans for addressing the impacts of invasive non-native species (INNS) requires the definition of clear priorities and tangible targets, and the recognition of the plurality of societal values assigned to these species. These tasks require a multi-disciplinary approach and the involvement of stakeholders. Here, we describe procedures to integrate multiple sources of information to formulate management priorities, targets, and high-level actions for the management of INNS. We follow five good-practice criteria: justified, evidence-informed, actionable, quantifiable, and flexible. We used expert knowledge methods to compile 17 lists of ecological, social, and economic impacts of lodgepole pines (Pinus contorta) and American mink (Neovison vison) in Chile and Argentina, the privet (Ligustrum lucidum) in Argentina, the yellow-jacket wasp (Vespula germanica) in Chile, and grasses (Urochloa brizantha and Urochloa decumbens) in Brazil. INNS plants caused a greater number of impacts than INNS animals, although more socio-economic impacts were listed for INNS animals than for plants. These impacts were ranked according to their magnitude and level of confidence on the information used for the ranking to prioritise impacts and assign them one of four high-level actions – do nothing, monitor, research, and immediate active management. We showed that it is possible to formulate management priorities, targets, and high-level actions for a variety of INNS and with variable levels of available information. This is vital in a world where the problems caused by INNS continue to increase, and there is a parallel growth in the implementation of management plans to deal with them.

Funding: The research and the workshop (December-2019; Centro Científico Tecnológico Patagonia Norte, San Carlos de Bariloche, Argentina) described in this manuscript were funded by the CONTAIN programme under the Latin American Biodiversity Programme as part of the Newton Fund (NE/S011641/1), with contributions from NERC, the Argentine National Scientific & Technical Research Council (CONICET,-2019-74-APN-DIR#CONICET), the Brazilian São Paulo Research Foundation (FAPESP 2018/14995-8), and the Chilean Agency for Research and Development (ANID; formerly CONICYT).

Acknowledgments
Thanks to the colleagues who replied to our informal questions about the usefulness of the methods and procedures described here. This informal survey of colleagues to obtain an initial critical evaluation was aligned with the policies relevant to the authors who contacted the participants. No one else had access to the responses and identities of the respondents. Servicio Agrícola y Ganadero, Gobierno de Chile, is one of the CONTAIN project partners, and it is represented by ER in this paper. However, the opinions and results presented in this document are entirely those of ER and may not represent SAG position on the topic. The Associate Editor and two reviewers provided feedback that helped improve a previous version of the manuscript.
