Gulleys Wood is an ancient woodland and is best seen from Beauchief Drive, as there are no paths. Ash, beech and sycamore are more abundant here than oak, and there are large areas of bluebells. Dog's mercury, yellow archangel, wood anemone, wild garlic and arum lily and several less common grass species are also to be found. Overall 10 tree species and over 50 herbaceous species have been recorded.
