Pteridium esculentum

Restricted Trade Species — ACT: Restricted Trade Species▾

Restricted Trade Species — ACT: Restricted Trade Species

Bracken (Pteridium) is a genus of large, cosmopolitan, coarse ferns in the family Dennstaedtiaceae. Brackens are noted for their large, highly divided fronds and are found on all continents except Antarctica; their typical habitat is moorland. The word bracken is of Old Norse origin, related to Swedish bräkencode: swe promoted to code: sv and Danish bregne, both meaning fern. In the past, the genus was commonly treated as having only one species, Pteridium aquilinum, but the current trend is to subdivide it into about ten species. Like other ferns, brackens reproduce by spores rather than seeds or fruit. The immature fronds, known as fiddleheads, are sometimes eaten, although some contain carcinogenic compounds.

How to spot it

Bracken is one of the oldest ferns, with fossil records from the Eocene period 55 million years old having been found. The plant sends up large, triangular fronds from a wide-creeping underground rootstock, and may form dense thickets. This rootstock may travel a metre or more underground between fronds. The fronds may grow up to 2.5 m (8 ft) long or longer with support, but typically are in the range of 0.6–2 m (2–6+1⁄2 ft) high.

Polystichum proliferum

Endangered — ACT: Restricted Trade Species, SA: Endangered▾

Endangered — ACT: Restricted Trade Species, SA: Endangered

Polystichum proliferum, commonly known as mother shield fern is an Australian endemic fern. The genus name Polystichum is derived from Greek poly - many, and stichos - rows referring to the many rows of sori. The species name is derived from Latin, Proli – offspring and fer - bearing referring to the proliferous buds, a prominent feature of the species.

How to spot it

Polystichum proliferum is a terrestrial fern that can grow to 130 cm in height. The rhizome and frond bases are covered in persistent scales which are glossy brown with pale edges. Fronds can reach up to 100 cm in length and 30 cm wide, are dark green when mature but lighter and paler when young. Sori (spore clusters) occur in rows on either side of the midrib and are covered with by a large umbrella-like indusium (protective covering) hence the common name “mother shield fern”.

Greater glider

Petauroides volans

EPBC-listed Endangered (uplisted 2022)▾

EPBC-listed Endangered (uplisted 2022)

Australia's largest gliding marsupial, the (southern) greater glider was uplisted from Vulnerable to Endangered under the EPBC Act in July 2022 after severe habitat loss from logging and the 2019-20 bushfires. It is a nocturnal, solitary specialist that feeds almost exclusively on eucalypt leaves and buds.

How to spot it

Look up into tall, hollow-bearing eucalypts at night with a spotlight - the eyeshine glows a bright orange-red. Body 35-46cm plus a long, non-prehensile bushy tail up to 60cm; fur ranges from a dark almost-black morph to pale mottled grey, always with a lighter belly. Unlike sugar or yellow-bellied gliders it is silent and solitary, gliding in long slow swoops between tall trees rather than bounding through the canopy.
