].
Although under severe pressure (the tree is classified as 'Criticaly Endangered'), the tree is still sometimes harvested from the wild for local use of its wood.
The species is severely fragmented; has a very small extent of occurrence; a very small area of occupancy; coupled with a projected continuing decline. The total population is less than 5,000 mature individuals in two locations. More than 90% are found in seven fragments around Port Boisé while the remainder are slightly inland at Forêt Nord where a smelter is being developed. This area is the focus of an ongoing restoration programme. Subpopulations in the immediate vicinity of Port Boisé are primarily threatened by fire. Genetic research indicates high levels of inbreeding as a result of fragmentation. The plant is classified as 'Critically Endangered' in the IUCN Red List of Threatened Species(2013)[
