2. The Meden Trail
The Local Nature Reserve is located on a disused railway track and features areas of grassland and woodland. A portion of the site is designated as a Site of Special Scientific Interest (SSSI). It is leased to the Nottinghamshire Wildlife Trust, which manages parts of the area on behalf of Mansfield Council. The reserve contains some of the best remaining calcareous grassland in the county, along with notable examples of calcareous woodland, scrub, and interesting limestone crags and fissures. The River Meden flows through the Vale, providing important marsh and aquatic habitats, with alder trees lining the riverbanks. The reserve is open to the public and is part of the larger Pleasley Trails network. Photo: Nottinghamshire Wildlife Trust

3. Maun Valley Park
Maun Valley Park Local Nature Reserve is the largest reserve in the district, covering 17 hectares of protected habitats along the River Maun, from Bath Lane to New Mill Lane. The reserve features ancient oak woodland, grasslands, water meadows, riverside areas, and wetland habitats. It is divided into two sections, North and South, by Old Mill Lane. Designated as a Local Nature Reserve in 2004, it holds significant value for both local residents and wildlife. The sandy banks and exposures of Sherwood sandstone along the river provide habitats for various insects and numerous types of fungi. The River Maun flows along the western edge of the reserve at the base of the escarpment, and it has played a vital role in the historical development of Mansfield, particularly in supplying water power to a variety of mills.
