État de la populationExpert

No quantitative population data are available for this species. It is known from 14 specimens, It is locally abundant in suitable habitat in the high Chimanimani (J. Timberlake, pers. obs.), but was rather scarce in the lowlands at Maronga in the southern Chimanimani (I. Darbyshire, pers. obs). In this latter area, it is likely that small populations occasionally establish from seed washed down from the mountains, but it was also well established at one wet grassland site.

Description complète des menacesExpert
Illegal artisanal gold mining activity on the Mozambique side of the border is concentrated in the river valleys and alluvial plains which support this species, but evidence from 2014 and 2016 fieldwork demonstrated that disturbance associated with low scale mining has led to significant population increases for this species (J. Timberlake, pers. obs). Mining activity is currently diminishing in scale due to exhaustion of accessible gold. The abundance of this species may therefore decrease naturally as the habitat becomes less disturbed and becomes recolonised by other species. Based on current evidence, this species cannot be considered to be threatened.
