This is a species with restricted range (area of occupancy of less than 2,000 km2). Recorded from Mt. Rwenzori and less common on Mt. Elgon. It is often found as pure stands which could be a disadvantage in case of fires, disease as whole population can be easily wiped out.  The species is also impacted by a quest for more grazing land for the surrounding communities and congestion by tourists resulting in degradation of bogs. It is therefore listed as Vulnerable.
