· Biomass reduction by grazing needs to be managed to enhance the range of grassland values, including rare plants, stony knolls and riparian verges.
The Craigieburn Grassland Interim Mangagement Statement, produced in 1998, includes much relevant information.
An area of approximately 100 ha of open space along and surrounding Merri Creek between Barry Road and Cooper Street including the 52.6 ha Cooper Street Grassland Reserve managed by Parks Victoria.
The Plains Grassland area is of national significance as habitat for two nationally significant species. The grassland was rated as having State (floral) significance (DCE 1990) and is one of the largest areas of relatively undisturbed native grasslands in the Melbourne area.
The Merri Creek and the River Red Gums along the escarpment are rated as State significance on the basis that the trees infrequently provide habitat for endangered species.
Cooper Street Grassland, together with Craigieburn Grassland and the link between, is listed on the Register of the National Estate (Australian Heritage Commission 1998). The listing was on the basis that the
Maintain intact riparian link upstream to Craigieburn Grassland and downstream to Barry Road Gorge.
DCE (1990) listed Cooper Street Grassland, as one of eight highly significant grasslands in the Melbourne area in private ownership. It recommended investigating its purchase by the government and reservation for conservation.
A small section (22 ha) was subsequently acquired by the state government as a Crown Land Reserve and is managed for conservation. A further 21 ha was added to the reserve in compensation for construction of the Craigieburn Bypass, and the Merri Creek frontage was transferred to Crown Land as part of a deal with the Istra Social Club which owned it as part of the title to their Clubroom area.
Approximately 40 ha of the grassland was lost in 2007-8 to industrial development.
At the southern end of the site there is a stream and floodway zone managed by Melbourne Water. In 2003 a group of wetlands were constructed on part of this site for stormwater treatment.
Strong consideration must be given to acquiring the creek frontage east side adjacent to the reserved land (and linking adjacent sites) from the private owners. In addition to protection of the important species and communities occurring there, and maintaining the habitat corridor - having control of the creek-line is important for protecting the reserved areas from incursions such as the infamous "Jerilderie Cattle Invasion of Merri Creek" of Nov 2002 - late April 2003. (Friends of Merri Creek 2003, p. 4-5)
There is less than 2% of Victoria’s original volcanic plains grasslands remaining. These grasslands are listed as critically endangered by the Federal Government. Click here for fact sheet. (external pdf).
This is why the Craigieburn Grassland Reserve is so important. The grassland covers approximately 400 hectares between Craigieburn Rd East and OHerns Rd in Melbourne's outer north. It contains Nationally Significant endangered plants such as the Matted Flax-lily Dianella amoena (external pdf) and Curly Sedge Carex tasmanica (external pdf). The grassland is also home to Nationally significant fauna such as the Striped Legless Lizard, the Plains-wanderer and the Golden Sun Moth.
To visit the Craigieburn Grassland Reserve permission must first be obtained from Parks Victoria.
Golden Sun Moth
The Golden Sun Moth is a sun loving moth that is found in the Craigieburn Grassland. The moth was only rediscovered in this area in 2003. Individuals start emerging from their cocoons around mid-November and are rarely seen later than mid-February. They live out their short adult life span in only a few days. See the Golden Sun Moth Lifecycle.
This critically endandered animal has made a friend in the Friends of Merri Creek who have planted 7,500 small wallaby grasses in the Craigieburn Grassland Reserve. These wallaby grasses are the favoured food for the Golden Sun Moth caterpillar . The female is thought to lay her eggs in the base of the grasses.
The grasses also provide a playground for the mating dance, with the male moth patrolling the grasslands between 11am and 2pm on sunny days, flying rapidly about a metre above the grass searching for females to mate with while dodging predatory dragonflies and birds.
Females rarely fly. They sit on the ground and flash their brilliantly coloured wings of metallic gold to attract the male (photo above: female Golden Sun Moth).
The Friends of Merri Creek and Merri Creek Management Committee have undertaken surveys of this critically endangered species. Look at a summary of the results of the Golden Sun Moth surveys. Click here for a more detailed report on the Golden Sun Moth surveys (pdf).

Craigieburn Grasslands is made up of Plains Grassland, Grassy Wetland, Stony Knoll Grasslands and Escaprment Shrublands
The Plains Wanderer is a small, rare ground-dwelling bird found in lowland grasslands, such as Craigieburn Grassland.
