Summerhill Lough ASSI
Physiographical interest of this largely spring-fed lough is related to the presence of calcium carbonate deposits, or marl, which are precipitated out of the calcium-rich water to produce a marl lake. This is a relatively rare lake type in Northern Ireland. Biological interest is related to the presence of vegetation communities which reflect these calcareous conditions, including a limited Stonewort Charophyte community.
