This species has a wide range and most of the population reduction is thought to have taken place more than three generations ago. There is evidence of decline today, but it seems to be a fairly slow rate of decline and confined to the smaller subpopulations. The population has become very fragmented due to historic clearance of large areas of habitat and as a result the remaining plants are increasingly isolated from each other and as a result regeneration is declining. In some cases there is no regeneration taking place and when the trees die there is local extinction, but it is hard to quantify what proportion of the population is impacted by this. If there were further information on the decline rates or of the area of occupancy, then it it might be close enough to the threatened thresholds to qualify for Near Threatened. The plant is classified as 'Least Concern' in the IUCN Red List of Threatened Species(2013)[

Species in this genus are generally adapted to growing in primary woodland. The seedlings are very shade tolerant, establishing well in the deeper shade of a woodland and then growing up to the light. They can sometimes be found growing in secondary vegetation, but they do not usually persist, being outcompeted by other, more light-tolerant species[

Propagation

Seed - best sown as soon as it is ripe in a cold frame. Some of the seed should germinate in the following spring though much of it might take another 12 months. Stored seed requires a period of cold stratification and can take 18 months or more to germinate. Prick out the seedlings into individual pots as soon as growth is observed and grow them on in light shade in the greenhouse for at least the next couple of winters, making sure to pot them on into larger pots as and when required. Plant them out into their permanent positions in early summer when the plants are at least 20cm tall.
