Blackberry and crack willow infestations along the upper Tarwin River and its tributaries were targeted in a coordinated weed control campaign. Working with several landholders, SGLN contractors and volunteers removed dense infestations across approximately 3 km of streambank.
Willows in particular cause significant problems in the Tarwin catchment by destabilising banks, increasing sedimentation and shading out native riparian vegetation. Removal is an ongoing priority for catchment health.
