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.

"" British zoologist George Rolleston theorised that the "domestic cat" of the Ancient Greeks and Romans was in fact the beech marten.
