État de la populationTexte officiel évaluation IUCNExpert
Specific to vernal pools. Seeds are not adapted for long distance dispersal as they drop into the water. Many vernal pools do not have this species occurring in them indicating that dispersal is limited.
Estimated total population size: >10,000;

Description complète des menacesTexte détaillé évaluation IUCNExpert
Habitat being degraded due to heavy grazing and trampling of plants floating in shallow pools, observed by Helme at Vanrhysdorp subpopulation and by Raimondo at some Nieuwoudtville subpopulations. Agriculture is also posing a low to moderate level threat as some farmers plough up these seasonal pools. This has occurred in Nieudoutville in 2005, but it is not general practice as crops do not grow well in seasonally inundated areas (D. Raimondo pers. comm. 2006). P.Goldblatt and J.Manning (pers. comm. 2005) also state that mining is a potential threat.
The specialized habitat requirements of this species may result in it becoming more threatened.
