Justification

This species is classed as Least Concern as it is widespread with stable populations and no major threats in most of its range. Populations in the south however are declining due to changes to hydrological regimes and need conservation attention.

Population

Population
C. acuta is widespread and abundant in Europe and populations are apparently stable in the northern part of the range. Occurrences in much of southern Europe are scattered and populations are locally decreasing due to drainage and hydrological measures.

Threats

Major Threats

There are no major threats to the survival of this species in most of its range. However, drainage and other measures affecting groundwater led to population declines in parts of southern Europe and locally elsewhere.

Carex acuta

Illustration of Carex acuta

Carex acuta or Acute Sedge, Slender Tufted-sedge,[2] Slim Sedge can be found growing on the margins of rivers and lakes[2] in the Palaearctic terrestrial ecoregions in beds of wet, alkaline or slightly acid depressions with mineral soil.

Carex acuta does not tolerate prolonged desiccation. The community is distributed, in particular, in northern France, the Low Countries, Central Europe south to the Sava and Drava valleys of Croatia, the northern Morava valley of Serbia and Romania, north to Poland, the Kaliningrad District, Lithuania and Latvia, in southern Scandinavia, in the Dnieper basin of northern Ukraine and southern Belarus, in the lower Volga Valley.[3]
