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 River Beech River The Beech River is a stream draining the east-central portion of West Tennessee in the United States. The Beech rises about northwest of Lexington, Tennessee. In the same area are the headwaters of two other West Tennessee rivers, the Big Sandy River and the Middle Fork of the Forked Deer River. The Big Sandy, like the Beech, is part of the Tennessee River system, whereas the Forked Deer system drains into the Mississippi River. The Beech River was named for the beech timber along its course. The Beech flows southeast into the town of Lexington and then primarily
