Plants and animals
You can occasionally find forests of reeds by Flade Lake. On the tidal meadows several species of orchids grow, including early marsh orchid and western marsh orchid, but also sea asters and common cottongrass.
Flade Lake has a good fish population with a great number of species, including perch, roach, bream, pike, whitefish, eel and especially zander. Both Flade Lake and Ørum Lake have a rich bird life. There are large numbers of waterfowl and wading birds. Breeding birds include greylag goose, shelduck, Eurasian teal, common ringed plover, redshank and black-tailed godwit. Of the lake’s resting birds note in particular the common pochard, common merganser and red-breasted merganser, golden plover, whimbrel and the bearded reedling.
