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 argentea lengthens to 2 to 7mm when the fruit is fully developed. It is found growing in a variety of habitats; open oak woodlands, rocky slopes, dry silted areas, and steep banks of streams, at 500 to 2000m above sea level. A genetic study showed that its closest relative is probably "Prunus haussknechtii". In warmer areas of Europe it is occasionally cultivated as an ornamental garden plant for its fragrant rose-pink flowers and attractive foliage, but it must be planted in a protected spot for best results. Prunus argentea Prunus argentea, sometimes called the silver almond, is a species of wild
