This project will focus on cats claw creeper control along Harpers Creek, upstream from its junction with the Mary River. The project aims to target sites furthest upstream, in keeping with the strategy to eradicate from the top of the catchment to prevent propagules being washed downstream by passive flow and flood waters, and infesting lower sites. Weed control methods will incorporate a mix of techniques including backpack and vehicle-mounted foliar spray, splatter-gun, cut-stump and basal barking on a site-by-site basis depending on the size of the plant, site access and weather conditions.


The Upper Mary Valley supports the ecological community of Lowland Rainforest of Subtropical Australia. Most of this rainforest occurs along streams and is susceptible to the smothering effects of Madeira vine and cats claw creeper. Eradicating weed vines is critical to the recovery of this rainforest.

The aquatic environment of the Upper Mary is home to the Mary River turtle, Mary River cod, Australian lungfish and giant barred frog. These species are threatened by the collapse of riparian vegetation and stream banks as a result of smothering weed vines.

Projects like this that work toward the stabilisation of ecosystems in the upper Mary valley have benefits for flood-control, biodiversity conservation, landscape connectivity, and reduction in sediment released to the Great Sandy Strait and the southern reaches of the Great Barrier Reef.
