RSPB bird sanctuary at Leighton Moss. SD477750.
Mosses took up a large part of the Lancashire Plain until the middle of the eighteenth century. The extent of the mosses led to isolated, scattered and poorly populated communities exemplifying the description of Lancashire as an impoverished backwater. Over a century, the drainage of the mosses yielded very productive arable land of rich dark soils. Few mosses remain. Leighton Moss is a surviving example and is an RSPB reserve.
