État de la populationTexte officiel évaluation IUCNExpert
P. acutifolius appears to be scarce throughout its range and in most areas from which information is available, is reported to be declining.
In Switzerland, P. acutifolius has apparently been lost from four out of five populations (Welten and Sutter 1982).
In Bulgaria, it is reported from only two sites (Assyov and Petrova 2006).
In Slovenia, it is recorded from only four tetrads (Jogan 2001).
In the UK, " P. acutifolius appears to be in gradual, long-term decline. Since 1960 it has decreased in Norfolk and become extinct in the London area and critically endangered in Dorset. However, several vigorous populations survive in Sussex" (Preston et al. 2002).
In France, it is reported from more than 20 departements and there is no suggestion of a decline, although it is protected in four departements.

Description complète des menacesTexte détaillé évaluation IUCNExpert
The cause of the reported declines is not clear, clearly a part is due to the loss and degradation of wetland habitats, but it seems likely that there is a more fundamental factor affecting P. acutifolius and it may be that although it tends to occur in naturally mesotrophic to eutrophic systems, it is unable to tolerate anthropogenic hyper-eutrophication.
In the Czech Republic, the decline is caused by the abandonment of traditional management of fishponds in favour of more intensive fish farming (Kaplan 2010).

Mesures de conservation recommandéesStratégies de conservation IUCNExpert
P. acutifolius is protected in France in the Alsace, Rhône-Alpes, Franche-Comté and Lorraine regions. It is listed as Critically Endangered in the Swiss Red Data Book (Moser et al. 2002) and in the Czech Republic (Procházka 2001). and in the UK and is listed as Vulnerable (level 3) in Germany (Ludwig and Schnittler 1996).
In the UK, it is included in three local Biodiversity Action Plans (Dorset, Norfolk and Sussex) and the National BAP.
More research on the species ecological requirements and potential threats as well as monitoring of the population trend are needed.
