Communities
Fern Gullies; Rainforest; Riparian; Wet Eucalypt Forest
Habitat Notes
Common and widespread in rainforest, wet sclerophyll forest and fern gullies from sealevel to rarely more than 500 m . The species likes dark, moist and sheltered sites and can hang in masses from waterfalls and other wet rock- faces. It also occurs as a terrestrial species on creek and river banks or, rarely, alluvial flats.
Site Tolerance
Moist; Rocky; Shady; Waterlogged
Frost Tolerance
Soil Tolerance
Fertile; Loam; Poorly-drained; Well-drained
General Notes
Fronds, or portions of fronds, containing ripe spores can be placed in a paper bag which is left upright in a dry and draught-free place. Spores should begin to release immediately and all spores are released within days unless the species has tough, leathery fronds. Spores settle at the bottom of the bag. Some species produce vast quantities of spores from one frond, others require dozens of fronds to produce the same amount. 2-4 weeks after sowing specks of green appear . These are the young prothalli and during the next 6-12 months they are at risk from overcrowding and pathogens. When the first fronds appear the sporelings can be slowly hardened by gradual removal of the container cover. Great care must be taken to avoid drying out. Prick out sporelings when the second frond appears. Suitable below powerlines.

Seed Information
Seed Collection
Collect spores when mature on the frond. unripe sori aregenerally light green then change to yellowish brown and to dark brown or black when mature. fertile segments on separate frond. see also general notes
Seed Treatment Method
Seed Storage Life
Viable Seeds Per Gram
Seed Treatment Notes
Sow spores into a pot in a water retaining medium with good drainage. Sterilise medium & containerwith boiling water and sow spores bysprinkling a small amount onto the surface of the medium. Cover immediately with clean glass or plastic wrap and leave in a warm area in strong light but not direct sunlight.
Germination Time
2-4 weeks
Suitable for Direct Seeding
No

N.B. Transplant only from nearby to avoid disease.
Yes
Cutting Notes
Ferns producing stolons such as Blechnum species can be propagated by removing offsets from the subterranean stolons. This method has a high success rate. Resets disturbance and is slow to establish.
