Kojonup Reserve stands out from the nearby cleared wheat belt country as a chaotic, magical bushland filled with chattering bird life.

The largest protected area of wandoo woodlands in the region, it shows us what this country was like before the destructive policies of the 1960s, when a million acres of WA bushland a year was burned, buried and bulldozed for broad-acre farming.

The reserve's canopy buzzes with insects, perfect prey for insectivorous birds such as the Golden Whistler. Many local bird species, such as the declining Rufous Treecreeper, nest in hollows in mature wandoo.

On the ground, fallen logs provide habitat for foraging birds such as White-browed Babblers, and even the scattered bark and leaf litter are important, protecting against soil erosion and providing food and shelter for invertebrates, reptiles and small mammals.

The woodlands' nectar-rich flowers feed honeyeaters almost year round, and the trunks of the sheoak trees make perfect springboards for lightning-fast Red-tailed Phascogales to leap around the canopy.

All this has been protected thanks to the generosity of our supporters.

What we’re doing

As a consequence of land clearing in this part of the world, large tracts of land are now threatened by salinity, and Kojonup Reserve is no exception.

The southwest corner of the property has been particularly hard hit, with areas of the native bushland dead or salt-affected. However, tree-planting in neighbouring properties seems to be yielding results, with the saline groundwater table remaining steady in recent years.

The only weed of significance on the reserve is Bridal Creeper and this is controlled every year to minimise its spread.

Phascogales on a mission

When dusk settles at Kojonup, if you know where to look, this reserve can put on a show you'll never forget.

Tiny marsupials called Red-tailed Phascogales, no bigger than the size of a couple of matchboxes, fly through the air, leaping two metres at a time and gripping the sides of trees, almost as if their feet were wrapped in Velcro.

Once common in this area, Red-tailed Phascogales have declined dramatically in numbers, and now have the dubious distinction of being nationally endangered.

Brought to Kojonup Reserve in May 2010 and 2011 from various sites in the WA wheat belt, 30 individuals – 16 females and 14 males – were released just ahead of their mating season. Their mission: to contribute to increasing the number of self-sustaining populations in the region.

Together with the WA Department of Biodiversity, Conservation and Attractions, we're monitoring the breeding success of the Kojonup population, which may help to save this species from extinction.

Cultural values

Kojonup is an Aboriginal name said to mean ‘place of the stone axe' (kodja) and the stone used to make it (kodj).

The O'Halloran family owned Kojonup Reserve between 1926 and 1996, and were so intent on protecting its woodlands that when it came time for them to sell they spent 10 years finding the appropriate buyer – Bush Heritage.
