Attention is has shifted to the rehabilitation of small areas and will eventually will conclude with the complete remediation of the Brukunga Mine.
The clay was heaped to form regular shaped bunds on the mine bench. The bunds were topped with a variety of scavenged covers of soil, mulch, pea-straw, bio-solids, and horse manure.
The trees provide a part screen of the footwall backdrop. The vegetated bunds will be surveyed in the summers of 2014/2015 to determine the effectiveness of each cover treatment.
In Autumn 2001, the former metallurgical plant site was covered with imported soils and horse manure, and sown to pasture grass. That June, Urrbrae High School students planted the area with tube stock. The combined vegetation of trees and established grass successfully reduced runoff from the area and prevented erosion of the surface cover.
