Mile Cross Marsh is adjacent to Sweet Briar marsh, which is a site of special scientific interest (SSSI). The marsh consists of an area of fen and an area of damp grassland.
A number of years ago a local resident dug a pond and this is used in spring by breeding frogs. There are a number of dykes dissecting the site, one of which is a storm drain which often contains foul water.
Species of interest: toads and water voles were recorded in the past, orchids.
Access: the site is used mainly as a short cut between Marriots Way and the River Walk.
Sycamore Crescent is a long narrow plantation of mature woodland adjacent to the River Wensum. The canopy is predominantly beech and oak. The under-storey contains elm and sycamore. The ground flora is composed of typical woodland plants red campion and some bluebell.
Species: woodland flora.
Access: wooden bridge over River Wensum, informal paths.
