État de la populationTexte officiel évaluation IUCNExpert
A rarely collected habitat specialist, known from only few, isolated collections, but recorded as locally abundant in these sites. The southern part of this species' range falls within the Pondoland region, which due to its inaccessibility is one of South Africa's botanically most poorly explored areas. This species has, however, been collected in all the well-collected sites within Pondoland such as Umtamvuna Nature Reserve, Mkambati Nature Reserve, as well as around Port St Johns, indicating that it is also likely to occur in undersampled areas in between. The KwaZulu-Natal Coast, which forms the northern part of this species' range is better sampled, however, it is also >90% irreversibly modified, with little or no suitable wetland habitat remaining. More surveys are needed to verify the number of existing subpopulations.

Description complète des menacesTexte détaillé évaluation IUCNExpert
This species is endemic to South Africa's most threatened biome, Indian Ocean Coastal Belt. Less than 50% of natural vegetation remains intact, and continues to decline rapidly. Within the northern part of this species' range, coastal grasslands have been predominantly converted to timber plantations, and remaining natural areas continue to be lost to expanding settlements and subsistence agriculture. This species has not been recorded in the coastal belt between Maputaland and Pondoland, however, this area is also extensively and irreversibly modified, predominantly to sugarcane plantations. Within the Pondoland region, the southern part of this species' range, habitat loss and degradation due to overgrazing and expanding human settlements and subsistence agriculture is also ongoing.
