État de la populationExpert

This species has been recorded at 11 localities and is known from only 14 collections and eight sight records, but is noted as frequent within its range, particularly frequent on the Mozambique side of the Chimanimani massif on schist grasslands in 2014 (A. Mapaura pers. obs.) and 2016 (T. Shah pers. obs.). Five sub-populations have been calculated through the grid adjacency method (Moat 2007). A population survey was conducted in the Mozambican Chimanimani mountains in May 2016, using a random stratified sampling method: 25 quadrats were sampled in 100 x 50 m macro plots. The total number of individuals was 160, with 140 mature individuals and 17 recruitment stage individuals (Shah 2016). The population data cannot be extrapolated for the wider massif due to the lack of reliable absence data, however this data now provides a framework for monitoring number of individuals in the future.

Description complète des menacesExpert
Morella chimanimaniana occurs primarily on open schist grasslands, which are prone to burning by natural fires on the Mozambique side of the Chimanimani massif. Although the species is adapted to natural burning regimes, there has been an increase in the frequency of burning, associated with the illegal artisanal gold mining and associated human activity within the National Reserve. As well as degrading the habitat quality this may prevent individuals from successfully regenerating and in turn impact the number of mature individuals. The impacts of burning on schist grasslands were observed in 2016 – the burning was fairly recent and individuals from some sub-populations were severely fire-damaged. However, it is also possible that fire frequency is now starting to decrease as illegal artisanal gold mining decreases on the high mountains, but this is not confirmed.

Threats to the Musapa Mt site are unknown. It is not protected, but does not appear to be threatened by agricultural encroachment according to recent satellite imagery.
