Environmental Issues

An example of Rocla's environmental efforts is the work being done at Gaskell Avenue.

Gaskell Avenue is Rocla's largest sand pit in Western Australia located 25 kilometres north east of Perth in the state forest. Set on 530 hectares of Banksia woodland our extractive industry licence is dependant upon successful rehabilitation performance.

Previous attempts to re-establish this woodland have been unsuccessful and so Rocla has sponsored the Kings Park Plant Science Division to conduct a program to research and develop restoration of Banksia woodland species after sand extraction. The Plant Science Division is one of the premier revegetation research organisations in Australia.

The research study has focused on all aspects of the rehabilitation programme from topsoil movement and compaction to seed and seedling survival rates after final planting. Progressive reports have resulted in changes to the rehabilitation process which has effected major improvements over subsequent years.

Rocla has become the Perth leader in rehabilitation techniques with Banksia woodland and the results are being used by Kings Park as the platform for urban woodland regeneration throughout Perth.
