EXST 2201 Chapter : Class 4 Silvicultural Systems
Document Summary
Silvicultural systems are name after the regeneration (reproduction) The regeneration (reproduction) method strongly directs stand development through tending, which consists of thinning, release, salvage, and sanitation. The regeneration method also strongly directs stand development through regeneration, whose activities depend on a source of cohort, which is either natural or artificial. The regeneration (reproduction) method defines patterns and frequency for overstory removed. Overstory removed puts light on the ground, which opens up growing space; this is an opportunity for a cohort. Overstory removed determines age structure, which is a distribution of a cohort. Overstory removed is most if not all even-aged, which is one cohort. Overstory removed most is two-aged; 2 distinct cohorts. Overstory removed in spots over time lead to uneven-aged, which is 3 or more distinct cohorts. Silvicultural systems are a way of organizing the various treatments into categories that are compatible with desired stand structure.
