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.
The Poem Tree The Poem Tree The Poem Tree was a beech tree with a poem carved into it by Joseph Tubb, located on Castle Hill at Wittenham Clumps in Oxfordshire, England. The tree, which was believed to be around 300 years old, collapsed through a combination of long-standing rot and inclement weather in July 2012. It died in the 1990s and after that, rotted completely while standing. The poem was carved in the 1840s. A stone, including a transcription and rubbing of the poem, was erected close to the tree in 1994 to commemorate the 150th anniversary of the carving. Tubb carved
