Third Australian Workshop on Native Seed Biology for Revegetation
The Newlands mine is situated in the northern Bowen Basin in Queensland and has been operating since 1983. In this time, approximately 1400 ha of spoil dumps have been created of which 764 ha are now rehabilitated. Rehabilitation requirements at the site include the establishment of native species ecosystem on recontoured spoil dumps. Newlands have utilised the novel 'benched' or 'internally drained' landform to improve native species establishment through reduced erosion, improved water retention for plant uptake and accelerated mine soil development.

The rehabilitation site within the closed Rhonda Mine had been used for coal and most of the surrounding area was left unvegetated due to the extraction of clay and brick materials and or landfill uses. The rehabilitated site is a small area about 100 m X 500 m and was probably a regulatory requirement for progressive rehabilitation of the Rhonda mine as the site was first area mined. Creating a visual buffer close to the road may have been another motivation for rehabilitating this site. Austral Bricks only recently bought the area and therefore records of planted species at the rehabilitated site were obtained from Hugh Taylor at Taylor Mining Services. The rehabilitation program ran from 1992 to 1995. No topsoil was used, the trees were planted directly into the waste material. Earlier trials had found these materials to be successful plant growth media. Approximately 3000 trees comprising six to eight Eucalyptus and Corymbia species were planted through tube stock on the rehabilitated site. There were no understory plants included in the rehabilitation program and after a three seed trial plot was unsuccessful, only Chloris gayana (Rhodes grass) was sown. A 1:250 000 scale map and vegetation description of Ipswich by Elsol (1991) provided a list of the common local species.
