The Craigieburn Grassland Conservation Reserve of 340 hectares is just 25 km from Melbourne and is located east of Merri Creek and mainly between O’Herns Rd and Craigieburn East Road, Craigieburn. Another smaller section of grassland, O’Herns Grassland is located to the south of O’Herns Rd, Craigieburn.

Grasslands are home to unique and rare animals and plants. A large number of grassland plants and animals are considered to be rare or threatened in Victoria, hence the need for the protection and management of these remaining areas of grasslands.
