The Callows is a stretch of the River Shannon at Shannonbridge that has a shallow gradient which results in seasonal flooding when heavy rain occurs. This has resulted in the formation of callows areas (wet grassland areas) which are rich in flora and fauna and a conservation area which is designated as an (NHA) Natural Heritage Area, (SAC) Special Area of Conservation and (SPA) Special Protection Area. The corn crake, which is rare and is protected nationally, is seen in the Callows area. Ducks, gulls, swans, and breeding waders including the northern lapwing, common redshank, Eurasian curlew and common sandpiper are also recorded within the area.
