Clones-Roslea Area IPA has been recognised as one of 165 Important Plant Areas in the UK.

The key features of this IPA are:

  • The species richness of stoneworts in surface standing waters
  • One of the best UK examples of threatened habitats of:
    Nutrient-poor waters with Stonewort algae
  • This low-lying area, on the borders of Monaghan and Fermanagh around the Finn River, is notable for its concentration of small calcareous ‘marl’ lakes.

    Levels of nutrients in marl lakes are low, providing a habitat to which stoneworts are particularly suited, which has resulted in this area being of particular value for its stonewort population.
