Plantations of such trees typically involves aerial drops of seed, followed by burning. Treeferns are common in rainforest and the understorey of eucalypt forests all over the east coast of Australia. The trunk is segmented and based on previous year's fronds. It is possible to cut the trunk at any point and replant the treefern. The roots descend all the way down the trunk and will take to the soil even if cut off well above the treefern's original base.
Some species grow marvellously tall and slender in protected locations.
Smaller ferns live on trees - both living and dead. This is the Little Franklin at a quiet, deep spot. Looking north over the Little Franklin valley as we walk home. Note differing colours of eucalypts indicating different species in different areas. In the foreground are the deeper green, mottled colours of multiple species of rainforest trees.
