Tuart (Eucalyptus gomphocephala) trees grow along a 400-kilometre band from Jurien Bay, on the northern margin of the Swan Coastal Plain, to the Sabina River, just east of Busselton.
It is estimated that before Europeans arrived there were more than 111,600 hectares of tuart woodland. Following clearing for agriculture and urban development, it is estimated that only 35 per cent remains. Remaining tuart woodlands have been disturbed by grazing, altered fire regimes and past timber harvesting.
Most tuart woodlands are now found at Ludlow, Yanchep and Yalgorup national parks. Significant tuart woodlands are also conserved in Bold Park and Kings Park, Myalup and McLarty, and at sites near Yanchep, Woodman Point, Port Kennedy and the Harvey Estuary. Smaller remnants of tuart are scattered across its natural range from Jurien to south of Busselton.
About 67 per cent of the existing tuarts are on freehold land.
Some approved clearing of tuart woodlands continues for urban and industrial land uses, road construction and the development of public infrastructure.
The 2003 Atlas of Tuart Woodland on the Swan Coastal Plain captures detailed data on tuart occurrence using high-resolution aerial photography. The mapping represented the most accurate assessment of tuart woodlands, and estimated that just over 30,300 hectares of tuart woodlands remained.
