Trees cut down to ground level and then allowed to regenerate. Most native trees, with the notable exception of pines, will regenerate from stumps (stools) or will send up suckers from the root system (notably elms).The vigour of an established root system will quickly send up a number of fast-growing shoots that will produce a crop of straight poles that can be used for fencing, wattle-work and fuel. The poles are harvested at intervals and allowed to re-grow again. The process can go on indefinitely and in many woods the oldest trees are the coppice stools – some may be as much as 1000 years old.One problem with coppicing is that the young shoots are vulnerable to attack from grazing animals, so they need to be excluded from recently coppiced areas.
