We’re excited to hit the ground running for the 2025 Arum Lily control season! Just like last year, we’re aiming for strong participation across the Shires of Capel and Harvey and the Cities of Bunbury and Busselton as we work together to tackle this extremely aggressive, invasive declared pest plant.

The Leschenault Biosecurity Group (LBG) is partnering with the environmental and natural resource management teams in the Shires of Capel and Harvey, the Cities of Bunbury and Busselton for implementation of this State Natural Resources Management (SNRM) funded program to tackle Arum Lily infestations through ground-based reconnaissance, mapping, treatment, and monitoring. This targeted initiative aims to address and control Arum Lily spread in eligible sites, helping to protect and preserve local ecosystems with much needed grant funding. LBG is providing overall administration of this program in addition to other project implementation tasks.
