It is estimated that 2% of Leicestershire's land area is ancient woodland, of which half has been replaced by new plantings in recent times. There are over 100 woods in Leicestershire believed to be ancient. The sites listed below are those over in size, and with one exception, all have SSSI status. With one group of woods near Hinckley, in the south-west, the remainder fall into three broad areas. In East Leicestershire, close to the border with Rutland, are the woods near Leighfield Forest, an extensive Royal Forest which straddled the two counties. North west of Leicester are the woods of Charnwood Forest. Further west are the woods of the coal measures toward the border with Derbyshire.
