[3] Polystichum proliferum is widespread and abundant from sea-level to 1300m a.s.l.,[4] but predominantly occurs in the tablelands and ranges of New South Wales, Victoria, Australian Capital Territory and Tasmania.

[3] Polystichum proliferum will however, occur in drier vegetation types such as coastal scrub and dry sclerophyll, due to its hardy characteristics such as the ability to tolerate salt-laden winds and poor soil quality.

The close association and similar appearance between the two species has often led novice plant to collectors to misidentify Polystichum proliferum as Dicksonia antarctica.

[1] Vegetative reproduction occurs when bulbils develop at end of the larger fronds grows into small plant.

[4] This characteristic allows Polystichum proliferum to colonise large areas vegetatively, often becoming the dominant ground cover after a disturbance and is a desirable trait for those who cultivate the species in home gardens.
