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.

Around 1920 a young miner and keen amateur gardener, Vic Stead, resided in Garforth. He regularly made the trip to Aberford by foot along the "Fly-line", a disused colliery railway, to see his girlfriend Nellie who worked there as a dairy maid. Near to Aberford Stead found three beech saplings growing in a row and grafted the central tree onto the two adjacent ones in a diagonal fashion to form the shape of the capital letter "N".
