The Bulga Complex is undertaking several initiatives which will see the restoration of heavily cleared and degraded farming land around our operations. Over a century of agricultural activities such as tree clearing and grazing has caused erosion, removal of woodland understorey and loss of important plant and animal habitats. Restoration initiatives at the Bulga Complex aim to link the remnant woodland communities together to create habitat corridors and maintain biodiversity of the area, creating a healthy and viable environment for future generations.
Southern Area Restoration
In the southern area of our underground operations, removing stock has seen natural regeneration of trees and shrubs. The natural regeneration has been complemented with extensive planting of native trees and shrubs.
Linking Remnant Vegetation
Some areas of cleared land have been planted with tree seed in order to link remnant vegetation providing wildlife corridors.
Restoring the Northern Drainage Line
The Northern Drainage Line Restoration Project aims to re-establish vegetation and stabilise the landscape after mining under the area. The area is showing strong initial success, with a mixture of riparian and woodland species establishing and progressing towards the correct ecological parameters for the Central Hunter Riparian Forest / Red Gum Woodland Complex community classification. Final rehabilitation will take place in 2011 following the completion of mining Longwall 14 and associated subsidence.
Restoring the Southern Drainage Line
In 2007, a drainage line in the south of the mine area was restored. The eroded channel, a tributary of Wollombi Brook, was stabilised to prevent further erosion and a dense corridor of vegetation was planted using native tree and shrub species. These riparian zones are important natural bio-filters and help to control erosion and encourage the return of wildlife.
Some of the seed used was collected from our woodlands with the aim of re-establishing local species and genetic diversity. Cattle have been excluded from grazing in the area to allow the riparian zone to flourish.
