État de la populationTexte officiel évaluation IUCNExpert

The taxon appears to be fairly common in most of its range. The number of individuals is not known.

Description complète des menacesTexte détaillé évaluation IUCNExpert

Alteration of habitat by changes in water level and overgrowth by woody species through succession are likely to be direct threats to this species however the taxon seems to be resilient to disturbance as it is often found on roadside ditches and volcanic slopes. The recovery potential of the taxon is likely to be good given its creeping rhizomatous mat-forming habit. The fact that this species has become naturalized in Portugal, Italy and Spain indicates that the species can adapt to foreign environments and is able to generate self sustaining and spreading populations with no human assistance (specimen data, Global Compendium of Weed, accessed 6th of June 2008).

Mesures de conservation recommandéesStratégies de conservation IUCNExpert

Eleocharis benefits from legal protection where it appears threatened e.g., in Maryland, Arkansas and Wyoming and some of the range occurs in protected areas. Wetlands are fragile ecosystems where a careful hydrological balance should be maintained and successional processes curtailed. Several areas where this species is found may be in need of maintenance or restoration. Population decline or spread should be monitored.
