Seekoeivlei Nature Reserve is a crucial habitat for over a quarter of the Free State’s endangered birds, and consists of a floodplain ecosystem, drained by the Klip River, with a number of small seasonally-flooded oxbow lakes.
Seekoeivlei is a breeding site for the whiskered tern, crowned and blue cranes and the endangered wattled crane. The little bittern and yellowbilled stork, both seldom seen, join the white-winged flufftail as rare species found here, and, as part of a large-scale rehabilitation project the wattled crane and the hippopotamus have both been reintroduced. The wetlands was named after the hippo last seen at the reserve in 1894 and stretches for about 20 kilometres.
