RFI - Ecological Assessment Report

Criteria for selection of vegetation to be retained shall be in general accordance with the
following points and as determined at the site inspection (see Point 4 above). Trees to be
considered for retention are to include those that:
1. Are currently of habitat value and are likely to continue to be of such value with the
   development in place.
2. Habitat trees are considered to be trees that provide or potentially provide a number of
   resources for arboreal and avian fauna, and may include:
     •       refuge/nesting/roosting opportunities – that is trees with hollows, fissures or cracks and
             dead (stag) trees;
     •       significant forage resources e.g. pollen, nectar, foliage, arthropods, for common fauna
             (eg. Banksia spp.); and
     •       significant forage resources for koala and glossy black-cockatoo (eg. E.tereticornis and
             A.littoralis).
3.       Specific approval is required for the removal or lopping of known Koala habitat trees in
         accordance with Residential Single Lots condition 36 and Residential High Density
         condition 34.
4.       Trees considered important for koalas in areas to be cleared (or adjacent to areas to be
         cleared) include E.tereticornis, E.robusta, C.intermedia, L.confertus, M. quinquenervia.
5.       Trees considered important for glossy black-cockatoos in areas to be cleared (or adjacent
         to areas to be cleared) include:
         •     all large trees (eg. E.tereticornis, E.robusta, C.intermedia) that may provide nesting
               resources;
         •     A.littoralis that exhibit suitable form and health; and
         •     A.littoralis that show signs of foraging activity.
6.       Do not affect existing or proposed infrastructure such as buildings, sewer lines,
         communication links, etc. Trees within 5m of a proposed structure will not be retained
         unless specifically nominated as important for retention.
7.       Are not likely to be affected by building works.
8.       Do not present a safety or maintenance issue (including long term safety and maintenance
         considerations).
9.       Are healthy and vigorous with an expected life span of at least 50 years. An arborist’s
         report shall be included in the relevant operational works applications in this regard.
         Consideration is to be given to risk to public safety and property from limb shedding and
         future obligations to carry out pruning.
10. Are of aesthetic value (including providing screening capabilities, form and shade).
11. Retention considerations are to take into account RHD condition 32 and RSL condition
    32.
12. Are critical for the retention of slope stability.
