Coal & Allied – Hunter Valley Operations 5.2.10 Native Seed Strategy During 2009 Coal & Allied continued implementation of the seed strategy developed in 2008. The main aims of the strategy are to: Select species that were present in pre-disturbance ecological communities; and Improve the diversity of the understorey and groundcover. The seed strategy will guide native seed collection, treatment and application techniques across HVO and MTW to maximise seed availability and quality for use in rehabilitation activities. 5.2.11 Habitat Audit ENSR Australia Pty Ltd conducted an audit of the habitat resources at HVO in areas ahead of the mining operations. This audit focused on presence/absence of tree hollows and stags with a view to the practical application of harvesting this material for use in the mine rehabilitation programme. The project objectives were aligned to the habitat requirement of the key fauna species as listed in previous EIS's for the site. Suitable trees were tagged with clearly identifiable weather proof tags with details recorded by GPS and ground truthing, with GIS data (using MapInfo software) provided to HVO Environmental staff for inclusion in their data sets. 5.2.12 Water Containment, Control and Distribution Rehabilitated areas have graded banks to control movement of waters derived from the newly rehabilitated country in order to minimise erosion. Sediment dams are also constructed where appropriate. Refer to Section 3.3 Erosion and Sediment Management for further detail. AEMR 2009 180
