Situated next to Bebington railway station, the site is of biological importance within Wirral. This urban nature reserve was developed on a former railway sidings and is now an oasis of green tranquility in densely populated urban area; its industrial past has been put to good use as a home for wildlife (e.g. on the thin, nutrient there are now carpets of wild flowers, including wild carrot & occasional bee orchids). Up to 26 species of butterfly have been recorded here, with 18 species breeding on site - giving the park its rather apt name. (Ref. 1, 2)
