    How River Landholders can Help

    River landholders hold an important role in maintaining river health and supporting the recovery of the Bellinger River Snapping Turtle. 

    1. Restore river banks

    Improving the condition of the riparian vegetation and stabilising riverbanks is important for maintaining water quality and habitat for aquatic animals in the Bellinger and Kalang rivers. Without action to protect and restore these important areas, it is likely we will see a gradual decline in the health of our waterways through reduced water quality, the loss of riparian vegetation for birds and wildlife, and the smothering of macroinvertebrates, native fish and seagrass habitats with sediments washed into the river from eroding riverbanks.

    Native vegetation plays a vital role in river bank restoration. Whilst erosion and deposition of sediment are natural river processes, the accelerated rates of erosion seen today are the result of removal of native vegetation over time through land clearing, over-grazing and other development pressures. This in turn leads to the loss of productive land and valuable habitat and impact on water quality and aquatic habitats downstream. The affects of accelerated erosion are especially significant during floods.

    Disturbance or destruction of river bank vegetation and weed invasion has also severely limited the ability of river banks to repair themselves through natural regeneration of vegetation between flood events.

    In their current state, river banks need active assistance and management to maintain and improve their stability and resistance to erosion. Planting river banks with native species which are adapted to the pressures of this dynamic environment is a valuable way to ensure our river estuaries remain healthy.

    The vegetation naturally occuring on estuarine river banks changes as the river water becomes less salty upstream. The Bellinger and Kalang estuaries have four vegetation zones characterised by particular groupings of plant species and their preferred location on the river bank. See the following for more info:

    2. Best Practice Stock Management

    Best practice for stock management should address the following aspects: Fencing, off-river Stock watering points, Formed access points.  Stock management is vital for riparian health to reduce:

    • Damage to riparian vegetation from grazing and trampling, leaving banks exposed.
    • Compaction of soil by hard hooves, subsequent erosion and degradation of the river structure.
    • Pollution resulting from sediment washing into the water course from erosion sites.
    • Stirring of sediment and damage to aquatic habitats caused by cattle loitering in streams.
    • Pollution resulting from cattle defecation.
    • Weed growth, through high nutrient loads from dung.
    • Stock exposure to water borne parasites, disease and footrot.

    3. Best Practice Fox Management

    Turtle nest predation by foxes are a major threat to the Bellinger River Snapping Turtle. Wild dogs kill and maul stock, threaten populations of native animals, have a social impact on farming and rural families, and are a reservoir for disease spread.

    Some misconceptions around baiting are that 1080 doesn’t work and that it kills wildlife, particularly quolls. In a 2007 baiting trial of 19 spotted-tail quoll, it was found that most, if not all quolls survived.

    It is important that landholders make use of all legal control methods. These include:

    • Baiting
    • Trapping
    • Shooting
    • Fencing

    Group baiting gives best control options. It is important to target optimum times of the year, be proactive, strategic, and targeted.

    Trapping is a great method for follow up after coordinated baiting programs or for targeting specific dogs. There are legal requirements involved.

    A recent letter to the Bellingen Shire Courier Sun by a farmer in Kalang called for more landholders in the Kalang Valley to join in our winter baiting program in 2019. To join, landholders have to do a free four-hour course with the Ag Dept to obtain a licence to bait. To enquire about the times and locations of baiting courses, contact Mick Elliott of the Grafton Ag Dept on 0408 352 174.

    4. Best Practice OSMS Management 

    On-site Sewage Management Systems (OSMS) are the treatment systems that collect wastewater from the home for the treatment and discharge into a septic system located within the property of unsewered areas of the shire. By maintaining best practice OSMS management, river landholders can contribute significantly to keeping our rivers healthy. For more info see:

    Volunteer With Us


    We are currently seeking Roving Volunteers and Holler Volunteers...

    Roving Volunteers

    Each month, more than 20 volunteer citizen scientists test across 22 sites along the Bellinger and Kalang rivers. Our roving volunteers are an invaluable part of the program. 

    Roving volunteers support the testing at core sites and step in if our water testing volunteers are ill or away. Also, if one of our volunteers move, or their commitments change, we fill these positions from our roving volunteers, who are fully trained, thus, we have no down-time when vacancies arise. 

    Being a Roving Volunteers involves being called upon as needed. Water testing is conducted on the second Tuesday and Wednesday of each month and roving volunteers are given site information and kit pick-up location information with as much notice as possible. 

    We estimate that roving volunteers might be called upon once every two or three months to test and recommend allowing 4 hours for testing, including travel time.

    Roving volunteers are trained in basic water quality testing by OzGREEN Co-Founder and CEO, Sue Lennox, and are supported by our Bellingen Riverwatch Program Coordinator, Amy Denshire. Volunteers also get to take part in fun educational workshops and events (e.g. bird spotting, aquatic plant identification, water bug blitzes etc.).

    It usually requires about two or three training sessions before volunteers feel comfortable to conduct testing on their own. Please download the latest version of the Volunteer Manual here (draft version) if you would like to read up on the training prior to get a feel for what's involved. 

    "I’ve loved sharing the information learnt with my children, and watching them learn, asking questions, and playing an active part in it." - Skye, Volunteer


    Holler Volunteers

    We are currently building a worldwide base of Holler Volunteers, who will help us get the word out about the plight of the turtle and help build support for this innovative citizen science project. Holler volunteers may be interested in volunteering to distribute flyers/posters, attend market stalls, collect donations, talk to prospective sponsors or assist with social media.

    Water Testing Volunteers

    A core part of Bellingen Riverwatch is the dedicated team of local volunteer citizen scientists, who undertake monthly water quality testing across 22 sites along the Bellinger and Kalang rivers. Volunteers have been trained in water quality monitoring techniques by lead scientists in the field and participate in extra optional training and workshops as the project unfolds (e.g. bird identification, water bug identification, etc). Watch video 


    Cassandra Vockler

    "I recently moved to Bellingen and my niece, Skye, invited me to come along with her when she was doing the water testing. Having recently retired from a career in science I thought it would be a great way to help collect vital data needed to further understand the increasing stresses we put on our environment. Good data collection is at the core of good science so it is fundamental that we collect as much as possible.It also helps me integrate into the community and  I get to spend time by the river with my niece.


    Skye Condon

    "In our little town of Bellingen, we are very lucky to have the Bellingen Riverwatch project making it possible for locals to become more educated and involved. I’ve loved sharing the information learnt with my children, and watching them learn, asking questions, and playing an active part in it. I’ve loved learning from the team and seeing their passion and enthusiasm around the project. I'd definitely recommend citizen science to anyone. It’s educational, inspiring...it’s a way to get involved in science and help."


    Jane Grebert

    I am grateful to have the opportunity to contribute to gathering baseline and ongoing data of our local river health. Various land uses in the catchment concern me such as unmanaged stock, clear fell forestry, and excessive or inappropriate fertiliser and pesticide use. I hope that my small efforts can help add to a bigger picture that will ultimately improve our care of the local catchment area and therefore the river health, for all the life it supports.

    What is Bellingen Riverwatch?

    In 2015, the Bellingen River Snapping Turtle (BRST) suffered a significant mortality event due to a disease outbreak in the Bellinger River. Since the mortality event, a disease investigation has identified a virus (Bellinger River Virus or BRV), previously not known to science, as the agent most likely to be responsible. A total of ~430 turtle deaths were recorded. The infected turtles suffered blindness, internal organ necrosis and developed sudden inflammatory lesions.

    Prior to this event, the population size for the species was estimated at 1600 – 4500 individuals. The current Bellinger River Turtle population is estimated to be between 200 and 300 individuals and predominantly juveniles and is listed as ‘Critically Endangered’ under the NSW Threatened Species Conservation Act 1995 and the Commonwealth Environment Protection and Biodiversity Conservation Act 1999. The BRST is endemic to this area and occupies about 55 km stretch of the Bellinger River. 

    During the mortality event, healthy BRST from an area yet to be impacted by the virus were removed from the river by the Office of Environment and Heritage (OEH). 16 animals were placed in temporary quarantine at Western Sydney University (WSU) and now are now part of a captive breeding program at Taronga Zoo. A second population of 19 juveniles was secured from the wild after the mortality event and will join the captive breeding program housed at Symbio Wildlife Park. The offspring from this program will be released back into the Bellinger River in future years.

    To maximise the Bellingen River Snapping Turtle's persistence in the wild, it is important that the river’s water quality is monitored consistently.

    Bellingen Riverwatch was born from a need to collect continuous, , scientifically rigorous water quality data to inform management decisions for the scientists involved in the recovery of the BRST. 

    This unique citizen science program engages 32 local community volunteers and 5 schools to collect monthly water quality data. Scientists from OEH carry out a comprehensive bi-annual water quality and macroinvertebrate survey, and assist with data analysis and interpretation. Read more


    1. To meaningfully engage the community to collect long-term, scientifically robust data to support recovery actions for the Critically Endangered Bellinger River Snapping Turtle ('Myuchelys georgesi') and other threatened species.
    2. To adopt a whole ecosystem approach and collect water quality data, monitor riparian vegetation, report turtle sightings and evidence of turtle nests, conduct water bug surveys, improve habitat and other monitoring activities directly contributing to science.
    3. To enable easy access and use of the data collected to aid decision making, guide research, inform policy, raise awareness and improve community understanding about the environment and threatened species.
    4. To increase awareness and understanding of river health and threatened species conservation leading to an increase in community environmental stewardship and responsible behaviour by tourists.
    5. To connect the community to expertise provided by various subject experts (e.g. scientists, ecologists, academics).
