Vegetation Benchmarks Scrub, heathland and coastal complexes Vegetation Condition Benchmarks version 2 Scrub, Heathland and Coastal Complexes SAL Acacia longifolia coastal scrub Community Description: This community normally occurs in a narrow strip along the coast, usually on parallel dunes, with Acacia longifolia subsp. sophorae dominant. It can vary from pure Acacia longifolia to mixtures with other species including Leucopogon parviflorus and Banksia marginata. The understorey is generally sparse.

Vegetation Condition Benchmarks version 1 Scrub, Heathland and Coastal Complexes SBM Banksia marginata wet scrub Community Description: Banksia marginata wet scrub is a dense wet scrub dominated by Banksia marginata usually occurring along creek lines and forest fringes within south-west buttongrass moorland. Common and abundant species include Melaleuca squarrosa, Leptospermum scoparium and sometimes L. nitidum and L. lanigerum. Gahnia grandis is usually present in the understorey and Empodisma minus or Calorophus species together with Bauera rubioides can form a dense tangle around the tree stems. There may be a few emergent trees of Eucalyptus nitida. This is the appropriate benchmark to use in assessing the condition of the listed Banksia marginata wet scrub community (Schedule 3A, Nature Conservation Act 2002).

Vegetation Condition Benchmarks version 1 Scrub, Heathland and Coastal Complexes SBR Broadleaf scrub: Olearia/Bedfordia facies Community Description: Broadleaf scrub is a closed-canopy scrub 4-8 m high which occurs where fire-frequencies are low, generally as patches within wet forest or openings in rainforest or along cliff tops in the south-east. Dominant small trees include any of Notelaea ligustrina, Pomaderris apetala, Beyeria viscosa, Bedfordia salicina, Prostanthera lasianthos and Olearia argophylla. In coastal sand sheet shrubberies Pomaderris apetala may share dominance with Cenarrhenes nitida and sometimes Monotoca glauca with a few Dicksonia antarctica and Anopterus glandulosus above a sparse fern ground layer. There may be sparse emergent eucalypts. This benchmark is one of 2 benchmarks available to assess the condition of SBR and is suitable for assessment of the core Olearia-Bedfordia-dominated expression of this vegetation. A separate benchmark is available for assessing the condition of the listed Notelaea-Pomaderris-Beyeria forest community (Schedule 3A, Nature Conservation Act 2002).

Vegetation Condition Benchmarks version 3 Scrub, Heathland and Coastal Complexes SCA Coastal scrub on alkaline sands Community Description: Coastal scrub on alkaline sand are scrubs in which the canopy varies from closed to open and patchy and dominant species depends on fire frequency and local species complement. Facies dominated by Myoporum insulare are distinct from those dominated by Leptospermum laevigatum. Diagnostic species include Zygophyllum billardierei, and Beyeria lechenaultii var. latifolia. Younger examples of the formation may be dense scrubs. In some older examples the understorey may be open and grassy and small byes may occur. In undisturbed examples, the understorey cover is often 100%. Regardless of location, this community is distinguished from other scrubs by having coastal species over a predominantly grassy and herbaceous understorey on deep alkaline sands.
