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". The underlying geology ensures that most of the site is well drained, favouring lime-loving plants – the calcicoles. There are, however, localised areas with poorer drainage
Prunus serrula typical of "Prunus", are produced in clusters of one to three. The fruit is a small oval bright red drupe. "Prunus serrula" is grown as a ornamental tree, especially for winter interest. It tolerates a variety of soil types and has a wide pH range. It prefers full sun and does well in USDA hardiness zones 5 to 8. Its potential as an invasive species is low, as it is susceptible to many common garden diseases and pests such as fire blight, powdery mildew and Japanese beetles. It is sometimes grafted to "Prunus serrulata" (Japanese cherry) crowns, forming a tree
