Abstract
The management of Scotch broom (Cytisus scoparius) in the Mount Arrowsmith Biosphere Region (MABR) poses a significant management challenge. As an invasive species, Scotch broom has severely impacted local biodiversity, increased fire risks, poses health challenges, and imposed socio-economic burdens. Individual actors and organisations are presently involved in Scotch broom management efforts, with action implemented on different scales and stemming from different reasons. While this approach has realised some benefit, a comprehensive management plan with criteria for prioritising actions is currently lacking. The importance of setting priority criteria for management strategies for invasive species is highlighted by Odom et al., (2005). A key reason for setting priority criteria is to help efficiently allocate resources available for Scotch broom management and foster consensus in its efforts. This study aimed to define priority criteria to be used in developing a Scotch broom management plan within the Mount Arrowsmith Biosphere Region (MABR). The criteria were defined based on multiple factors deemed important for effective management, based on literature as well as themes emerging through interviews conducted. Importantly, there is emphasis on the involvement of Indigenous peoples in the Scotch broom management process, acknowledging traditional knowledge systems and indigenous peoples’ deep connection to the land. By integrating multiple environmental, social and economic considerations, we sought to provide MABR with strategies for prioritizing Scotch broom control efforts. Actions taken in this project included brainstorming, literature reviews, interviews, thematic analysis, and reflections. Given limited resources, we developed a spatially explicit decision making method to identify effective management actions and minimize the likelihood of reinvasion. The priority criteria defined in this study as well as the action plans aim to optimize resource allocation for Scotch broom prevention and control efforts, contributing to the sustainability of the region. In conclusion, this study offers a crucial element for developing a comprehensive management plan for Scotch broom in the MABR, by considering ecological, social, cultural, and economic dimensions to enhance sustainability and resilience in the region.
