Bewick and Beanley Moors in association with old collapsing heather bushes. Conifer plantations aside, the moors have little woodland cover; what exists is found on the boundaries and following the paths of streams at lower elevations. Spwecies include alder ("Alnus glutinosa"), hawthorn ("Crataegus monogyna"), brown birch ("Betula pubescens"), rowan ("Sorbus aucuparia") and occasional ash ("Fraxinus excelsior"), and ground-cover of yellow pimpernel ("Lysimachia nemorum"), wood sorrel ("Oxalis acetosella") and smooth-stalked sedge ("Carex laevigata"). As with the bogs, so the woodland also provide transition locations, such as from wet birch-wood to purple moor-grass or to bogs of lesser pond-sedge ("Carex acutiformis"). Other wood species found include
Sorbus aucuparia tart, and aromatic, and candied or used in compote. The two cultivars are self-pollinating, yield fruit early, and the sugar content increases while the acid content decreases as the fruit ripen. 'Beissneri' is a cultivar with reddish foliage and bark and serrated leaves. Other edible varieties originate in and are named after Klosterneuburg, Lower Austria. Russian botanist Ivan Vladimirovich Michurin began in 1905 to crossbreed common "S. aucuparia" with other species to create fruit trees. His experiments resulted in the cultivars 'Burka', 'Likjornaja', 'Dessertnaja', 'Granatnaja', 'Rubinovaja', and 'Titan'. Other "S. aucuparia" hybrids planted in Western Europe beginning in the 1980s
