Loss of biodiversity and habitats is one of the greatest threats to the environment and education has a critical role to play in addressing this issue. This paper describes a teaching activity for first-year university students studying sustainable resource management at the University of Newcastle which established a partnership between education, government and the community to rehabilitate a nature reserve where biodiversity values were threatened by weed invasion. Students research the problem (weed invasion), quantitatively assess the impacts of weed invasion and management interventions, and work alongside a community-based bushcare group and government agency during on-ground rehabilitation of the reserve. Key outcomes for students have been knowledge and skills relevant to a critical issue for the Australian environment; a more optimistic attitude towards environmental issues and their potential to develop solutions; a positive perspective about the role of community involvement; continued participation in community bushcare groups outside the classroom; and personal involvement in solving a critical environmental issue.
