An area of 39.1 hectares in the north-west corner of Geddington Chase has been designated a biological Site of Special Scientific Interest (SSSI).

[1][2] Geddington Chase is a surviving fragment of the medieval Royal Forest of Rockingham.

Most of the Chase is commercially managed, and the SSSI is an area of semi-natural wet ash/maple woodland on Midland boulder clay.

The ground flora is diverse, with plants including bluebell, dog's mercury, tufted hair-grass, and a few wild daffodils.

[3] The site is private land with no public access.
