The Bardney Limewoods National Nature Reserve is a collection of small woodlands near Bardney in Lincolnshire. The reserve includes about half the Limewoods in the area. Cocklode Wood, part of the Bardney Limewoods, is the best surviving spread of medieval limes in England.
The Limewoods are diverse in tree species and ground species, but are dominated by the Small-leaved Lime Tilia cordata. Linguistic and placename evidence suggests that the very name of Lincolnshire is anciently associated with the Lime, Linde being the Saxon name for the tree.
Bardney Limewoods NNR is managed by the Forestry Commission. A visitors centre is maintained at Chambers Wood Farm. The NNR is said to include a quarter of the county's ancient woodland.
