We are now five years into our project and are progressing well against all our objectives.  We have been  overwhelmed by the positive response the Rivers of Carbon project and approach is attracting in our local community. Highlights include:

  • 56 sites, 771.2 ha and 123.3 km stream (target met of 120 kms)
  •  Rapid Appraisal of Riparian Condition and site assessment conducted on all Rivers of Carbon sites
  • Linking of Rivers of Carbon data with Boorowa River Recovery data (to enable analysis of 20 years of riparian rehabilitation data to be reviewed)
  • Production of the Edition 37 RipRap Magazine on ‘Rivers of Carbon – Rivers of Life’
  • Presentation at the 18th International Riversymposium
  • Upload of five Rivers of Carbon stories to the Riverspace website – www.riverspace.com.au
  • River of Carbon Yass River Linkages and Rivers of Carbon – Upper Murrumbidgee projects progressing well
  • Fish surveys being conducted on Yass and Boorowa Rivers in November-December 2016
  • Production of RipRoc story telling platform
  • Installation of a rock wall in Blakney Creek to protect Southern Pygmy Perch from alien fish

All of out Rivers of Carbon project use the same model of focusing on sites with high recovery potential for biodiversity and carbon sequestration, as well as connecting riparian areas so that we have contiguous corridors of vegetation along streams.  The co-investment approach we are using provides testimony to the success of the Rivers of Carbon model. The biggest challenge for Rivers of Carbon at the moment is the increasing demand and keeping up with requests!

In the photo below you will see one of our sites along Jeir Creek (that flows into the Murrumbidgee) that we are excited about, as the landholder is fencing   back at least 25 metres to create a riparian corridor.  This site has high recovery potential and links to previous work upstream and downstream – we are filling in gaps to connect the creek and create a continuous riparian corridor.  Luke Pearce from DPI Fisheries will be doing a fish survey on this site to see what is living here.  We think it could potentially be a site to release Southern Pygmy Perch in the future.

We have a mix of riparian and wetland sites, with a few of these linking to remnant grassy box woodland or shrubby forest.  We also have some gully erosion sites that we are stabilising to prevent sediment travelling into the river.  We are categorising our sites according to three Themes:

Theme 1: Biodiverse plantings
Theme 2: Recruitment and regeneration of native vegetation
Theme 3: Managing invasive species

tube-stockPrior to work commencing,each site is thoroughly assessed for its recovery potential, its habitat significance, riparian linkages, cost effectiveness in terms of outcomes, and carbon sequestration opportunities.  We also ensure that we collaborate with the relevant Catchment Management Authority to assess the priority of the site in-line with their Catchment Action Plan.

To date we have 56 sites and all of these have had a  Rapid Appraisal of Riparian Condition Assessment  undertaken to provide baseline information against which we can track progress against over the life of the project.  We also record other details to complement the Rapid Appraisal of Riparian Condition assessment, for example, stream type, stream class and bank profile.  We have a webpage focusing on our monitoring and evaluation approach as we feel it is vital we track before and after riparian rehabilitation works are undertaken.

Once we have planned the works to be undertaken on site with the landowner, we prepare individual species lists for each site based on pre-1750’s vegetation (GIS mapped) and any remnants that are on site.  Plants are also chosen with regard to their position in the landscape and moisture availability.  Planting tubestock is a key part of the Rivers of Carbon project, as many sites cannot be direct seeded due to high fertility, grass competition and accessibility.  For example, only two of the currently approved 24 sites has been suitable for direct seeding and are due to go ahead this year.

Seed propagation of plants for is ongoing, and is part of Greening Australia’s broader effort to grow 100 000 known provenance plants in association with the seed collection program (undertaken over December/January) for all projects.  Riparian community species are part of the species mix, and are being grown specifically for Rivers of Carbon.  Seed for growing tubestock is sourced from local provenances and each plant grown can be traced back to the origin of the seed.  Tubestock and seedstock are chosen based on the specifics of each site.


 In a recent review of past restoration sites we have recorded some recruitment of native vegetation to fenced sites – with regeneration of Eucalypts, and significant regeneration of native grasses in sites that still retained these remnants.  In many of our Theme 1 sites (Biodiverse Plantings) however, pasture grasses dominate, and fertility is high.  This limits the ability and speed at which native vegetation is recruited. These sites are mostly being planted using tubestock.

Theme 2 (protecting and enhancing native vegetation) sites have a higher level of natural regeneration overall compared with Theme 1 sites as there is vegetation remaining on site.  These sites also tend to be native pastures, rather than exotic pastures, and this makes it easier for regeneration to occur.  We have found that regeneration of native grasses is significant depending on the level of disturbance, once fenced out bare ground is very quickly colonised. Overstorey and mid storey regeneration is starting to occur at some sites, however, this process can take some time. A number of sites still require mid story to be reinstated.

Our Theme 3 (managing invasive species) sites are mainly focusing on Crack Willow, as this is the main willow species to be targeted in the Rivers of Carbon project area.  Willows are a particular problem in smaller streams where they invade the entire stream causing erosion of banks and stream widening. They also reduce diversity of habitat for macro-invertebrates and use a considerable amount of water. Any willow control being undertaken will be in conjunction with rehabilitation of habitat and associated fencing and revegetation as an imperative. Funding available for willow control is limited. Control will involve stem injection with Glyphosate at some sites, while other sites will require an excavator with specialised attachment (log grab, saw, rake and sprayer). The most appropriate option depend on cost, safety and specific site requirements (in terms of ongoing management). These methods have proved successful in the Rivers of Carbon project area in the past.

We are continuing our work with the Southern Pygmy Perch and the community that is established in the Pudman is still there and breeding.  This is brilliant, as the Southern Pygmy Perch is endangered and had been wiped out in many other NSW streams.  We have recently installed a rock wall on Blakney Creek to protect the Southern Pygmy Perch from invasion by Redfin and European Carp – you can read more on that story here.

To get a more detailed understanding of the work we are doing, here are four stories from landholders who are part of the Rivers of Carbon team:

In addition, we have a range of River of Carbon products designed to assist people who want to learn more about riparian rehabilitation.  All of these are in the resources section of our site and you might also want to read about the theory and practice behind our project on our ‘What is a river of carbon’ page.  The RipRoc story telling site is also a great way to keep up to date with what we are doing.
