Living stump
Living root remains of a cut or otherwise dead tree / From Wikipedia, the free encyclopedia
A living stump is created when a live tree is cut, burned, eaten, or infected, causing its cambium to die above the root system.

Living stumps are generally characterized as having a thin outer layer of living cells that surround a hollow central cavity. [1]
Living stumps can survive for several years by
- using excess carbon reserves,
- transfer of nutrients from the roots of neighbouring trees, often aided by mycorrhiza[2] or
- root grafting to the root system of living trees.
Root grafting allows for carbon transfer from living trees to living stumps resulting in incremental cambium growth in the stump.[3]
Stumps can grow a callus tissue over its cross section which prolongs longevity of the stump by protecting it from infection and insect damage.[4] A living stump which is capable of producing sprouts or cuttings is known as a stool, and is used in the coppicing method of woodland management.[5]
