Banksia Oblongifolia - Distribution and Habitat

Distribution and Habitat

Banksia oblongifolia occurs along the eastern coast of Australia from Wollongong, New South Wales in the south to Rockhampton, Queensland in the north. There are isolated populations offshore on Fraser Island, and inland at Blackdown Tableland National Park and Crows Nest in Queensland, and also inland incursions at the base of the Glasshouse Mountains in southern Queensland, at Grafton in northern New South Wales, and Bilpin and Lawson in the Blue Mountains west of Sydney.B. oblongifolia grows in a range of habitats—in damp areas with poor drainage, along the edges of swamps and flats, as well as Wallum shrubland, or coastal plateaux. It is also found in open forest or woodland, where it grows on ridges or slopes, or heath. Soils are predominantly sandy or sandstone-based, though granite-based and clay-loams are sometimes present.

Associated species in the Sydney region include heathland species such as heath banksia (Banksia ericifolia), coral heath (Epacris microphylla) and mountain devil (Lambertia formosa), and tick bush (Kunzea ambigua) and prickly-leaved paperbark (Melaleuca nodosa) in taller scrub, and under trees such as scribbly gum (Eucalyptus sclerophylla) and narrow-leaved apple (Angophora bakeri) in woodland. The Agnes Banks Woodland in western Sydney has been recognised by the New South Wales Government as an Endangered Ecological Community. Here B. oblongifolia is an understory plant in low open woodland, with scribbly gum, narrow-leaved apple and old man banksia (B. serrata) as canopy trees, and wallum banksia (B. aemula), variable smoke-bush (Conospermum taxifolium), wedding bush (Ricinocarpos pinifolius), showy parrot-pea (Dillwynia sericea) and nodding geebung (Persoonia nutans) as other understory species.
