Bunyip State Park with Latrobe Valley Naturalists



A few days ago some Heyfield Birdwatchers joined some of the Latrobe Valley Field Naturalists for a walk around the Button Grass Walk in the Bunyip State Park and I was introduced to some new and fascinating plants. Birds too, such as the Southern Emu-wren, Brush Cuckoo and Blue-winged Parrot and Restless Flycatcher were some of the better ‘gets’ for the day.

This walk is a good place to see a representative of one of the oldest plants still living – Bushy Clubmoss, a fern ally that is a descendant of a giant tree that grew 300 million years ago and reached heights of 20 metres.

Another interesting plant we ticked was Fairy Aprons. These odd little things are bladderworts  and are carnivorous – they have tiny bladder-like traps that capture minute prey that swim in water saturated soil.
How could something this attractive be carnivorous?

The Buttongrass that the walk is named after grows in damp nutrient poor soils and is a sedge, not a grass. It has button-like flowers on the end of long stalks and is more plentiful in Tasmania where it is thought to be an important food source for the Orange-bellied Parrot.

Thanks Alix, Ken, David, et al for a great day.
