Harvest and Regeneration Systems
A harvest and regeneration method (also called a silvicultural system) is a combination of timber harvesting and site preparation practices that prepare a site for natural or artificial regeneration. There are many different methods along a continuous spectrum to fit different site conditions, stand sizes, timber values, current and desired future tree species, landowner objectives, and other factors. Depending on the method you choose, the reproducing stand will be even-aged or uneven-aged.
Although the focus is often on the harvest, equally important are the conditions established by the harvest. These conditions, along with follow-up care and tending of the new stand, will determine the future development of the woodland. For this reason, foresters prefer the term ?gregeneration methods?h (or systems) over ?gharvesting methods.?h A regeneration method focuses on the future stand. A harvest method focuses only on the arrangement and means by which mature trees are removed.
Even-aged Regeneration Systems
Even-aged harvest and regeneration systems require complete removal of the overstory resulting in a new stand where nearly all the trees are the same age. Even-aged systems usually are economical to implement because the landowner can remove a large volume of wood at one time for sale and they offer many options for site preparation. Even-aged systems are appropriate to:
These systems offer some, but not all, of the growing conditions that naturally occur following a major fire or windstorm.
