Mast (botany) Mast seeding is defined as the highly variable production of fruit by a population. These intermittent pulses of food resources drive ecosystem-level functions and forest dynamics. The difference between a mast seeding year and a non-mast seeding year can be thousands of acorns, hickory nuts, beech nuts, etc. Mast seeding dominantly occurs in wind-pollinated tree species, but has also been observed in grasses and Dipterocarps. Masting, in the strict sense of the term, occurs only in monocarpic (or semelparous) species, whose members reproduce only once during their lifetime, then die. Hypothesis for the evolution of mast seeding can broadly be
Nellie's tree as "the tree" in the singular form it is actually three separate beech trees that have been grafted together. 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".
