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 marten During heavy snowfalls, the beech marten moves through paths made by hares or skis. In an area of northeastern Spain, where the beech marten still lives in relatively unmodified habitats, one specimen was recorded to have had a home range of with two centres of activity. Its period of maximum activity occurred between 6-12 PM. Between 9-6 PM, the animal was found to be largely inactive. In urban areas, beech martens den almost entirely in buildings, particularly during winter. The beech marten does not dig burrows, nor does it occupy those of other animals. Instead, it nests in naturally occurring
