Description complète des menacesExpert
Although 48% of this habitat has already been lost to ploughing - it occurs amongst rocks so is relatively safe, the ploughing between sites is likely to be affecting geneflow between populations.

Grazing is also a potential threat especially as these areas are all used for livestock and livestock concentrate around these seasonal moist areas (the farmer adjacent to the Nieuwoudtville reserve has no Cynalle aquatica despite having the correct habitat type due to over grazing.) S. Todd also observed no seed set due to grazing pressure.

Climate change is a very high potential threat facing this species.
