The meadows along the bank of the Shannon are known as the "Callows", (from the Irish word "Cala" which means a riverside meadow).
These lands are flooded in
winter. Since the land has to dry out before the grass can be harvested, the
callows are cut late in the summer.
For this reason, the corncrake, which has
become extinct in the rest of Europe, survives in the callows of Lusmagh.
The Callows contain many unique species of plant, including the Lusmagh Orchid.
