Plants occur primarily on steep to precipitous stony sites, but previously they occurred on flatter land which has since been cleared. There has been massive seed collecting from natural habitats and leaves are exported in large numbers for decorative purposes. Current populations are considered to be stable and so the plant is classified as 'Least Concern' in the IUCN Red List of Threatened Species(2010)[

Species in this genus form structures known as coralloid roots. These roots branch off from the taproot or secondary roots and are distinctive in that they grow laterally or upward, forming a nodular mass at the apex. These coralloid roots occur slightly below or slightly above the soil surface and generally contain cyanobacteria, also known as blue-green algae. These are able to fix atmospheric nitrogen and make it available as a nutrient to the plant. The ability to extract this important nutrient from the air explains how many cycad species are able to survive on almost sterile soils[
