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 Creek (Pennsylvania) Beech Creek (Pennsylvania) Beech Creek is a tributary of Bald Eagle Creek in Centre and Clinton counties, in Pennsylvania in the United States. Via Bald Eagle Creek, its water flows to the West Branch Susquehanna River, then the Susquehanna River, and ultimately to Chesapeake Bay. Beech Creek is born at the confluence of the North and South Forks, upstream of Kato, and flows for to join Bald Eagle Creek, downstream of the borough of Beech Creek. The abandoned grade of the Beech Creek Railroad follows it along its length, running from its mouth up to the North Fork. At one
