Description:
A native of South-eastern Queensland, Fishbone Fern is a groundcover with
fronds up to 1m high. It forms large clumps growing outwards from a central core
within a short time
Many water tubers are attached to the dense rhizome network
Tiny brown spores are on the underside of fronds.
Dispersal:
Its spores, held on the underside of the frond, are spread by wind. It is also
spread by water and dumping. It spreads vegetatively from its thin wiry underground
rhizomes.
Impact on Bushland:
The root system spreads effectively to seal off the soil surface and reduce the
penetration of rainwater. It effectively outcompetes other groundcovers.
Control:
| Manual: |
The whole plant is easily dug out. |
| |
The water tubers will not regrow, but as they are closely attached to the
thin rhizome network, it is best to remove the entire root system. |
| |
Dispose of carefully and systematically weed out new regrowth. |
| Chemical: |
Please contact your local control authority for
advice on chemical control. |
