. The IUCN cites "land clearance" as the justification for the vulnerable status of ''Normanbya normanbyi''. While much of the area where it grows is protected under both Queensland's National Park system and the World Heritage listing, there is also a significant portion of lowland rainforest that is privately-owned, uncleared land, and which has an uncertain future in regard to the preservation of the natural habitat.


Cultivation

''Normanbya normanbyi'' is visually very similar to the very popular Foxtail palm (''Wodyetia bifurcata'') but is not as widely planted as the latter. It may be grown from fresh seed and is also available at many plant nurseries. It requires a shady position when young, well-drained soil and plentiful water.
