Our Work
The Yarran Dheran Advisory Committee holds a range of environmental based community activities. These activities aim to increase local community awareness and knowledge of the environmental values of the Reserve, and they provide people with an opportunity to learn more about the local ecology and how to help care for it.
Yarran Dheran Advisory Committee
The City of Whitehorse appoints a committee of volunteers to provide practical support and advice to Council on issues relating to the management of the reserve. The advisory committee’s main focus is to protect and enhance Yarran Dheran’s biodiversity and to foster community appreciation of its environmental values. The advisory committee conducts various activities such as regular working bees, activities with school groups, presentations and guided walks which encourage greater community interest in the reserve and the local flora and fauna. It also particpates in Clean Up Australia Day and National Tree Day each year. The advisory committee meets every three months.
Contact yarrandherancommittee@gmail.com if you are interested in being a member of the advisory committee, if you would like to become a member of the Friends group that undertakes monthly working bees, or if you would like to join any of the activities described below
Environmental Events
The advisory committee organises public environmental information events that are held in the Yarran Dheran Information Centre throughout the year as part of the committee’s Annual Calendar of Events.
These events include a guest speaker with particular expertise on a specific aspect of the flora and fauna of the local area and are normally followed by a guided walk. The events are open to the public and are free of charge. The number of people able to attend each event is normally limited so prior booking is required. A list of upcoming events and relevant contact details can be viewed on the home page.

Melbourne Water’s Waterwatch program is a citizen science program which monitors the current health of our local waterways.
It assesses what is currently impacting on the health of our local waterways and identifies opportunities for stream rehabilitation and education programs and projects.
Over the past 150 years our catchments have undergone significant change, due to urban development, vegetation removal, grazing, increases in hard surfaces and construction of stormwater systems.
These have all meant that the health of our local waterways is under threat, impacting on the survival of all aquatic life, including native fish, and the macro and micro organisms that live in the creek.
At Yarran Dheran, we test water samples taken from specified points along the Mullum Creek on a monthly basis for water quality, using water quality indicators to test for phosphorus, electrical conductivity, turbidity, pH, ammonium and dissolved oxygen and report results to Melbourne Water.
For records of sampling results for our two sites, see Quarry Road and Tandarook Crescent Donvale.

This is a citizen science activity which you are welcome to join.
The committee conducts a quarterly survey of frog species heard in the ponds at Yarran Dheran as part of Melbourne Water’s Frog Census and the Australian Museum Frog ID program at FrogID – The Australian Museum.
These surveys are held in January, April, July and October during the early evening and provide an opportunity to learn how to use the Melbourne Water Frog Census app and to identify the calls of the seven species of frogs that may be found at Yarran Dheran.
The community is encouraged to record frogs in their own locations and for records of Yarran Dheran Seasonal Frog Records (sightings and/or calls see Yarran Dheran Seasonal Frog Register_July_2025 Note that records are updated as they are confirmed by Frog Census or by Frog ID.
Please contribute to our own data by providing any information from personal surveys when you receive confirmation.
