Bardney is surrounded by ancient woodlands composed primarily of lime trees, known collectively as Bardney Limewoods. Lime forests are rare in the United Kingdom, where oak is generally the dominant climatic climax species. The flora of the woodlands is indicative of ancient woodland, including "Allium ursinum", "Hyacinthoides non-scripta" and "Circaea lutetiana", as well as several species of wild orchids. Wildlife in the limewoods includes deer, Eurasian jay, European hornet and purple hairstreak butterfly.
