Although Foxes Lair remains the centre of the world, I thoroughly recommend a drive in the Yilliminning area in Spring. Head east out of Narrogin on Herald Street/Harrismith Road for about 15kms, turn left on to Birdwhistle Road then right into the reserve. The map below show a circuit through wonderfully diverse bush and farmland. Click on the image to see a larger version.
First some flowers in wandoo-sheoak woodland on the north side of the rock. Of special note are slender spider orchid (Caladenia flaccida subsp. Pulchra), green spider orchid Caladenia falcata and similar but less common smooth-lipped spider orchid Caladenia integra. Magnificent plants!
The rock itself is a granite inselberg (bedrock outcrop), rising to approximately 48m, with commanding views across the farmland and remnant vegetation. I love the small oases of mosses and plants including the early September lemon orchid that nestle in water gaining areas and gnarled Kunzea pulchella with its stunning red flowers in late spring, that thrives in cracks in the rock. The rock was originally strewn with exfoliated sheets of weathered granite that sheltered rock dragon lizards. Unfortunately most have been destroyed by 4WD vehicles (a pox on them!)
