In 2020, A Rocha Australia volunteers in the Toowoomba area of southern Queensland were commissioned to start controlling invasive plants and weeds at two bushland parks managed by the council, in collaboration with a local community organization, Friends of the Escarpment Parks.

The first project is a five hectare remnant of blackbutt-dominated eucalypt forest. This is an endangered regional ecosystem in Toowoomba’s outer suburbs at Nielson Park. Invasive plants like lantana and asparagus fern are removed, allowing indigenous understorey species to establish. The other is removal of Cat’s Claw Creeper at Redwood Park, a larger council reserve on Toowoomba’s eastern escarpment below the watershed of the Great Dividing Range. This plant has smothered trees and shrubs in semi-evergreen vine thicket (‘softwood scrub’ or ‘dry rainforest’), destroying the canopy and ruining this endangered ecosystem. Threatened species include Black-breasted Button-quail and Powerful Owl, as well as fruit-bats and orchids. It is slow and laborious work but highly rewarding as mature trees are cut free and seedlings are discovered under masses of creeper, taken off the ground layer.
