PLANNING & ENVIRONMENT COMMITTEE MEETING AGENDA                                            9 APRIL 2019

    type is seldom found in the field. Where the source of degradation is less dramatic, such
    as eutrophication of the aquifer via nutrient pollution from surrounding land use
    practices, or alteration to the drainage patterns of the aquifer, the understorey of the
    community can become dominated by weed species such as Para Grass (Brachiaria
    mutica) and the canopy species exhibit progressive die-back. This scenario is repeated in
    many of the Melaleuca communities which are downstream of agricultural or pine
    plantation areas where nutrient pollution of the aquifer has occurred. "

    The Vegetation Community present on the property is best defined as Melaleuca
    quinguenervia tall open forest to tall woodland, The Forest Assessment Unit and
    Queensland Herbarium Department of Environment have mapped and classified this
    regional ecosystem in South East Queensland in the project "Forest Ecosystems Mapping
    and Analysis " as part of the Queensland CRA/RFA process.
    This vegetation community is classified as vulnerable, and results of this survey indicate
    that the extent preclearing of this vegetation community was 51,000 ha, and the current
    extent is 18,500ha. 7% of this vegetation community is in protected areas and 2% in State
    Forests. Further to this the effects of clearing between 1995-1997 indicate a loss of 700
    hectares (or 3.6% of 1995 area} during this period.
    The Vegetation Community described in the Forest Ecosystem Mapping and Analysis
    report is as follows:
    Regional ecosystem 12.3.5
    Description: Melaleuca guinguenervia tall open forest to tall woodland on Cainozoic
    alluvial plains in coastal areas. Understorey depends upon duration of waterlogging with
    sedges and ferns especially Blechmum indicum in wetter microhabitats and grasses and
    shrubs in drier microhabitats. Other tree species that may be present as scattered
    individuals or clumps include Lophostemon suaveolens, Eucalyptus robusta,
    E. tereticornis, Corymibia intermedia, Livistona australis, Endiandra sieberi. Melastoma
    affine and Glochidion sumatranum and Euodia elleryana are often in understorey.
    Provinces: 4, 8, 10.
