This document summarizes a research project aiming to develop culturally appropriate models for engaging indigenous communities in biosecurity issues. The project is a collaboration between researchers in Australia and New Zealand. It establishes an Indigenous Reference Group and Industry Advisory Network to help guide the development of engagement models. The models will be tested and refined with the goal of enhancing indigenous communities' ability to manage biosecurity threats in culturally sensitive ways. One engagement model presented is based on traditional Aboriginal practices for detoxifying cycad nuts, using the process as a metaphor for relationship-building and knowledge-sharing. End users praise the research for centering indigenous perspectives to strengthen biosecurity protection of native plants.
