Mt Matilda
Wongan Hills is a series of mesas (flat topped hills), with Mt Matilda the highest at 434 metres above sea level. Unlike other hills in the region, Mt Matilda is not granite. It is laterite, or limestone gravel, which supports an abundance of rare, natural flora.
Mt Matilda Reserve is home to 1400 plant species of which 28 are rare. This is the rarest flora population in Western Australia and 22 of the plant species are found only in Wongan Hills.
Most important of all is the Wongan triggerplant (Stylidium coroniforme subsp. Coroniforme). This subspecies of the triggerplant is only found in the Wongan Hills, and by 1980 the known population had declined to one plant. This was caused by inappropriate fire regimes, trampling by stock, salinisation, weed competition, and human traffic. Since then, several recovery plans for the plant and have seen a sizable recovery in its population.
You can walk the Mt Matilda Trail (7.3km long) with 9 lookouts to enjoy spectacular views. There is also a shorter Wildflower Trail (4.8km).
