This notice is about the 1km permissive footpath that starts at Three Bridge Mill, goes along Padbury Brook, see SP6727 : Padbury Brook near Three Bridge Mill, and then rejoins the public footpath to the village of Hillesden. The footpath was established under the Department for Environment, Food & Rural Affairs' farm conservation scheme, and a badge on a nearby gate says 'DEFRA Conservation Walks'. As well as a map of the route, the sign says that 'beside the path is an arable margin that buffers the stream from arable operations whilst creating a habitat for invertebrates & small mammals'.
