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 cerasus Belgium. Prunus cerasus Prunus cerasus (sour cherry, tart cherry, or dwarf cherry) is a species of "Prunus" in the subgenus "Cerasus" (cherries), native to much of Europe and southwest Asia. It is closely related to the sweet cherry ("Prunus avium"), but has a fruit that is more acidic. The tree is smaller than the sweet cherry (growing to a height of 4–10 m), has twiggy branches, and its crimson-to-near-black cherries are borne upon shorter stalks. There are several varieties of the sour cherry: the dark-red morello cherry and the lighter-red varieties including the amarelle cherry, and the popular Montmorency cherry.
