Structure and physiognomy

    • The canopy is generally dense and less than 10 m in height (Keith 2004; Beard et al. 2013).

    • Foliage of dominant shrubs or trees is sclerophyllous and varies in size from nanophyll, (0.25 – 2.5 cm2) to microphyll (20 – 45 cm2).

    • Sometimes forms a dense canopy with a projected foliage cover of 70 – 100% which can limit light penetration, reducing the understorey to shade tolerant grasses and sedges (Keith 2004; Beard et al. 2013).
