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.
Dwarf Beech and Italy ("Alberi serpente", nel Monte Pollino). A similar form is the Weeping Beech ("Fagus sylvatica" Pendula Group), which has more pendulous branching. Dwarf Beech The Dwarf Beech, "Fagus sylvatica" Tortuosa Group, is a rare Cultivar Group of the European Beech with less than 1500 older specimens in Europe. It is also known as Twisted Beech or Parasol Beech. It is a wide-spreading tree with distinctive twisted and contorted branches that are quite pendulous at their ends. With its short and twisted trunk the Dwarf Beech grows more in width than height, only seldom reaching a height of more than
