List of local nature reserves in Northamptonshire

[4] A ridge of low Jurassic hills runs through the county, separating the basins of the Welland and Nene rivers.

The county has good communications as it is crossed by two main railway lines and the M1 motorway, and it has many small industrial centres rather than large conurbations.

Twelve are managed by the Wildlife Trust for Bedfordshire, Cambridgeshire and Northamptonshire, and two are also Sites of Special Scientific Interest, Ramsar internationally important wetland sites, and Special Protection Areas under the European Union Directive on the Conservation of Wild Birds.

The largest site is Titchmarsh Nature Reserve at 72.7 hectares (180 acres), which has nationally important numbers of goosanders, wigeons and gadwalls in winter.

[7] The smallest is Great Oakley Meadow, which has prominent surviving ridge and furrow from the medieval ploughing system.
