How Hill Track
How Hill Track is a 3.1 hectare biological Site of Special Scientific Interest east of Mildenhall in Suffolk. It is in the Breckland Special Protection Area under the European Union Directive on the Conservation of Wild Birds. This is described by Natural England as a grassland site which provides suitable conditions for seven rare plants, including perennial knawel, small alison, purple-stem cat's tail and sickle medick. There is access to this site, which is now mainly woodland, from a footpath which runs along its southern edge.
