Rivers of Carbon –
We are honoured to work on the ancestral lands of the Ngarigo and Ngunawal people, and we recognise their continuing connection with, and knowledge about land, waters and community. We pay our respects to them and their cultures; and to Elders past, present and emerging.

Why Upper Bidgee?
The Upper Murrumbidgee River is a special place, with rich biodiversity, cultural heritage and communities keen to protect and restore the social and environmental assets the region contains. Our projects in this stretch of river are varied, and include adventurous volunteering, fish habitat creation, riparian revegetation, erosion control and community engagement. Our overarching focus is on connecting riparian habitat along the river as it has been historically cleared, and heavily impacted by erosion and large amounts of sand deposition.
We like to protect what is in good condition first, and then link those areas to enable species like fish to move up and down the river. To do this we are improving connectivity between the high quality habitats of the Bredbo and Colinton Gorges which lie upstream and downstream of the Bumbalong Valley. Along with landholders we are removing weeds, stabilising banks and planting native vegetation. By addressing the issues in the Bumbalong Valley, we are creating a continuous 40km river corridor connecting both Gorges. Revegetation works in this part of the reach are also helping to protect and extend an old growth Eucalyptus viminalis floodplain woodland remnant. Some of the trees in this remnant are estimated to be up to 300 years old.
A similar situation exists in a stretch of river between the Colinton (in NSW) and Gigerline Gorges (in the ACT) in an area known as the Boathole/Angle Crossing area, with degradation of riparian corridor due to the infestation of woody weeds reducing riparian condition along the river. With our latest funding from the NSW Environmental Trust we are now extending our efforts to include the Strike-a-Light River, where we will stabilise the upstream catchment to reduce inputs of sand sediment at source, addressing the cause of the problem rather than remediating it downstream. Another site is at Bush Heritage Australia’s Scottsdale Reserve, where we will try to re-establish an area of river tussock (Poa labillardieri) grassland. Such grasslands are naturally found along the valley floors and have important stabilising, filtering and habitat values. Unfortunately these grasslands have in the past been extensively cleared on alluvial floodplain areas of the upper Murrumbidgee.
Our ongoing works to improve the upper Murrumbidgee River will help protect and enhance the habitat of Murray cod, Macquarie perch, Murray River crayfish, Water rats (otherwise known as Rakali), Platypus and Eastern long necked turtles, which are all known in the project area. If you know this beautiful part of the world, or perhaps even have the great luck to live there.
Upper Murrumbidgee River Project Area
Outcomes achieved so far:
13 landholders involved
Working across 13 sites
4.6km of riparian area fenced
27.5ha of riparian area protected and 44ha revegetated
Planting of 12,200 plants
4 erosion control sites
277ha of weed control
6 activities, 500+ people engaged
Crown Lands willow removal project
Willows are among the worst weeds in Australia because of their invasiveness, potential for spread, and economic and environmental impacts. The purpose of this sub-project was to treat invasive willow species along the upper Murrumbidgee River to enhance high quality native riparian vegetation found within the Bredbo Gorge.
This work has helped to protect an area of priority native fish habitat, and prevented further weed incursion of willows into riparian rehabilitation works which have been implemented downstream as part of the Rivers of Carbon Upper Murrumbidgee River Rehabilitation project.
