Grass Wood, Wharfedale cleared through selective felling, many areas of the woodland have the appearance of an early successional stage of advance natural regeneration through mainly saplings of ash, birch and sycamore, this enclosed within a variable canopy of ash, sycamore, beech, oak, and with some birch. Shrubs and small trees in the understorey include bird cherry "Prunus padus", hazel, spindle "Euonymus europaeus", buckthorn "Rhamnus cathartica", wild privet "Ligustrum vulgare", blackthorn "Prunus spinosa" and guelder-rose "Viburnum opulus".
