SCHEDULE 1

Honeymyrtle shrubland on limestone ridges of the Swan Coastal Plain Bioregion

The Honeymyrtle shrubland on limestone ridges of the Swan Coastal Plain Bioregion is the assemblage of plants, animals and other organisms associated with a type of warm temperate shrubland or heath.

The ecological community occurs in southwest Western Australia. It is known to occur in relatively small areas, at several locations in the Swan Coastal Plain IBRA Bioregion. It occurs on the slopes and tops of limestone ridges on the Swan Coastal Plain.

It is a shrub-dominated ecological community, with sclerophyll shrubs forming a shrubland, thickets or heathland, above a typically diverse ground layer of herbs, including sedges, Restionaceae and occasional grasses.

The ecological community is dominated by Melaleuca huegelii (chenille honeymyrtle), Melaleuca systena (coastal honeymyrtle), and/or Banksia sessilis (parrot bush); commonly over Acacia lasiocarpa (pajang), Grevillea preissii (spider net grevillea) and Spyridium globulosum (basket bush). Other common shrubs include: Acacia rostellifera (summer-scented wattle), Banksia dallanneyi (couch honeypot), Gompholobium tomentosum (hairy yellow pea), Hardenbergia comptoniana (native wisteria), Hibbertia hypericoides (yellow buttercups), Leucopogon parviflorus (coast beard-heath) and Templetonia retusa (cockies tongues).
