Mast (botany) some domestic animals consume. Mast is found in two forms. Mast is generated in large quantities during mast seeding events (or masting, mast events). Mast seeding is a population-level phenomenon that is hypothesized to be driven by economies of scale, weather, and resources. These pulses of resources drive ecosystem-level functions and dynamics. Tree species such as oak, hickory, and beech produce a hard mast—acorns, hickory nuts, and beechnuts. It has been traditional to turn pigs loose into forests to fatten on this form of mast. Other tree and shrub species produce a soft mast, such as raspberries, blueberries, and greenbriar.
Beech been widespread in Europe since the 17th century. Beech has been listed as one of the 38 plants whose flowers are used to prepare Bach flower remedies. The beech most commonly grown as an ornamental tree is the European beech ("Fagus sylvatica"), widely cultivated in North America and its native Europe. Many varieties are in cultivation, notably the weeping beech "F. sylvatica" 'Pendula', several varieties of copper or purple beech, the fern-leaved beech "F. sylvatica" 'Asplenifolia', and the tricolour beech "F. sylvatica" 'roseomarginata'. The strikingly columnar Dawyck beech ("F. sylvatica" 'Dawyck') occurs in green, gold, and purple forms, named after
