État de la populationTexte officiel évaluation IUCNExpert

There is little information available on the status of populations of B. alpestris, but populations appear to be stable in most of their range. The range can be divided into two types: firstly highland rivers and glacial lakes where the species is relatively undisturbed by human influence and secondly lowland sites which are under heavy anthropogenic influence and face several threats. The populations in around 15-20 sites are threatened (Kozlowski et al. 2009b).

Description complète des menacesTexte détaillé évaluation IUCNExpert

There are several threats such as hydrological changes, pollution, and eutrophication which affect the populations. Especially the lowland populations suffer from those threats as they are mainly surviving in very isolated, polluted and transformed ponds (Kozlowski et al. 2009, G. Kozlowski pers. comm. 2010).

Mesures de conservation recommandéesStratégies de conservation IUCNExpert

Baldellia alpestris is protected under the legislation of the Spanish province Castilla y Leon. A microreserve has been created for this plant. It also occurs in protected areas in Portugal. The threatened lowland populations require conservation attention such as appropriate site management and protection. Monitoring of the populations is recommended.
