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-maple forest of American witch-hazel and alderleaf viburnum shrubs. The ground cover includes herbs and spring ephemerals, flowers which are able to bloom before the canopy fills in. Seedlings of beech and maple trees are shade-tolerant, allowing them to grow in low light conditions for several years. These seedling are waiting for an opening in the canopy, and grow rapidly when an opening is made by the death of a mature tree. Beech-maple forests are often found on flat or rolling terrain, in a variety of moist to well-drained soils with high levels of organic matter. They thrive in glacial till from
