Council is undertaking a range of biodiversity projects across the valley. These projects address biodiversity decline by controlling weeds and replanting with native vegetation, thereby providing habitat for native species.
As part of a Fish Habitat Action Grant, Council has started removing camphor laurel and other weeds from along the Coldstream River. There is a strong link between healthy tree lined waterways and improved water quality including increased fish stocks . Removing camphor trees allows for native species to re- establish which provide habitat for insects (and are food for fish!). Stem injection is the most common method for controlling large camphor trees, however on property the landholder’s organic status prevented the use of chemicals, and instead ringbarking was used. This is a slower and more time consuming method to use, but will achieve the same results as chemical control.

Council’s bush regeneration team have recently completed some weed removal work along Chatsworth Village’s riverfront reserve. Riverfront (riparian) areas can support diverse vegetation, provide bank stability, improve water quality of the river by acting as a filter for sediment, and provide habitat for native species. However these areas are vulnerable to degradation by weeds which can out-compete native vegetation, and reduce the diversity of native species. Weeds can easily be spread through dumped garden clippings. Garden waste including palms fronds should not be dumped in the reserve, but placed in the green bins provided by Council. Dumping of garden waste can attract an on-the-spot fine of up to $4000.

This Spotted-tailed Quoll (Dasyurus maculatus) was captured on Council’s wildlife camera as part of a monitoring program near Grafton recently. Spotted-tailed Quolls are mainland Australia’s largest carnivorous marsupial (about the size of a cat), preying on possums, bandicoots, rats, insects and reptiles. They are nocturnal and require a large territory to roam, and make their dens in rock shelters and hollow logs. They are a threatened species in our area.

Koalas are long term residents of the Clarence. Koalas eat the leaves of some Eucalyptus trees and individuals favour only one or a few species. They need good quality habitat with plenty of their favourite food trees and suitable shelter sites. Some koalas have a favourite individual tree, so a single tree in your garden may just be a favourite. Koalas are vulnerable to habitat disturbance, dog attack, car strike and bushfires. Across the Clarence Valley there appears to be two distinct populations of koalas, those in the Upper Clarence which includes areas such as Shannon Creek, Waterview Heights, Clouds Creeks State Forest, Nymboida and those in the Lower Clarence which includes areas such as Ashby, Woombah and Iluka localities. Together we can ensure they remain safe and healthy. Clarence Valley Council has developed a management plan for the Koalas at Ashby, Iluka and Woombah.

Council has been working with the Maclean Flying-fox Working Group (FFWG) that was formed in late 2009 to address the conflict between humans and flying-foxes in the Maclean area.
The key objective of the FFWG was the development of a comprehensive strategy for the management of flying-foxes in Maclean.
The Maclean Flying-fox Managment Strategy consists of a range of management options and a program of short, medium and long term actions to achieve both these objectives. The strategy also aims to identify opportunities to promote positive interactions between the wider community, flying-foxes and their habitat.
