Description complète des menacesTexte détaillé évaluation IUCNExpert
Agricultural transformation to wheat is a severe past and present threat (J. Manning pers. comm. 2005). These vernal pools are completely surrounded by wheat fields, the farmers are unaware of the biodiversity within the pools pools are being degraded by being filled in and by allowing large numbers of stock to trample in the pools.
Of the five farms visited by CREW in 2005 in the Sandvlei Kooperfontein area all had vernal pools in degraded conditions. Only one pool at the entrance of Sandvlei had this species still on it.
