[1][2] Felsham Hall and Monkspark Woods are designated a 63.3 National Nature Reserve, also called Bradfield Woods,[3][4][5] and are managed by the Suffolk Wildlife Trust.

[6] These woods have a history of coppicing dating to before 1252, producing a very high diversity of flora, with over 370 plant species recorded.

Uncommon woodland flowers include oxlip, herb paris and ramson.

There is also a rich variety of fungi, with two species not recorded elsewhere in Britain.
