Bordering the Merri Creek and now surrounded by industrial uses, the reserve supports large areas of Plains Grassland and patches of Red Gum Plains Grassy Woodland. Along the Merri Creek are stands of Woolly Tea-tree, Riparian Scrub and Escarpment Shrublands. Bababi Marning (Cooper Street) Grassland Nature Conservation Reserve is an important part of the larger Merri Creek Marran Baba Parklands which is a critical biodiversity corridor through Melbourne's northen suburbs from Mt Ridley all the way to Yarra Bend Park
Between Cooper Street, Metrolink Circuit and Merri Creek in the northern Melbourne suburb of Campbellfield
None apart from a pedestrian path connecting the southern section of the reserve to Whittlesea Public Gardens on the east side of Merri Creek and Merri Creek Parklands to the south.
In 1990 the Victorian Department of Conservation and Environment 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.
Bababi Marning (Cooper Street) Grassland Nature Conservation Reserve has a high degree of habitat variation and is of State to National significance for its flora and fauna and has Plains Grassland, a relatively intact Brown-back Wallaby-grass seasonal wetland, Escarpment Shrubland and Riparian Scrub. The Woolly Tea-tree riparian scrub is considered to be the most intact in northeastern Melbourne. The endangered Amphibromus pithogastris was present at the site but located in the area now under development. The rare species Agrostis aemula var. setifolia is also present. In terms of fauna, the Cooper Street site is considered to be of State significance due to the presence of the nationally significant Golden Sun Moth, Growling Grass Frog and Striped Legless Lizard, also Swift Parrots have been sighted at the southern end of the grassland.
