Land Use and Management • When mixed with other less fertile land types in a paddock ,
Recommendations black basalt areas are at risk of overgrazing . Monitor land condition and adjust management to reduce grazing pressure if necessary .
• When in poor condition , can be rehabilitated or converted to sown pastures .
• Suitable for cropping in stone-free areas that have access to irrigation .
• Rotational wet seasons spelling to maintain perennial pasture composition .
• Heavy grazing encourages germination of introduced weeds , particularly parthenium .
• Maintain at least 50 % ground cover at end of dry season to maximise infiltration and reduce soil erosion .
Land Use Limitations • Flooding and waterlogging .
• Restricted access in wet conditions .
• May be heavily grazed by feral deer .
• Weed invasion ( parthenium ).
• Establishment problems with improved pastures due to crusting / cracking or coarse self-mulching surface .
Conservation Features and • Extensively thinned , cleared or cultivated in many areas .
Related Management • Springs associated with these communities are significant for local fauna and may support endemic flora .
• Discharge areas may have associated salinity risk .
• These areas ( including springs ) may be subjected to high total grazing pressure .
• Subject to invasive weed species such as parthenium , rubbervine , grader grass and mimosa .
