My new locale in West Gippsland has brought me closer to the tall wet forests of the Baw Baw and Strzelecki Ranges. I am beginning to come to terms with a whole different set of ecosystems, habitats, and their associated flora and fauna.
Over a couple of recent days I have been visiting the beautiful Mt Worth State Park just south of Yarragon. A couple of the Mt Worth ‘friends’ are introducing me to some of the noteworthy species that can be seen within the park.
One of the first things I needed to sort out in my brain was the differences between the two principal Tree-ferns, Soft Tree-fern, (Dicksonia antarctica), and Rough Tree-fern, (Cyathea australis).
Apparently it goes like this ...
Prefers more damp situations deep in gullies, beside creeks, etc. They have fibrous or hairy trunks, the fronds are often convex in cross section and their stipes, the stalk that supports the fronds, are smooth. Soft Tree-ferns often have epiphytes of various sorts growing on them.

Can tolerate drier places on hillsides, etc. When the old fronds drop off, the old knobbly bits of stipe remain visible on the trunk. The fronds are much flatter in cross section. The stipes themselves are rough toward the base, like sandpaper.

While all this ‘research’ was going on, I was entertained by numerous birds and I often found it hard to concentrate on the ferns. Just within the carpark of the picnic area it wasn’t difficult to tick at least half a dozen rather nice species – Rose Robins, Eastern Whipbirds and the very shy Olive Whistler amongst them.

Thanks Merrin and Paul – great fun!
