Table 1. RELATIONSHIP OF STANDARD SILVICULTURAL TREATMENTS TO OBJECTIVES AND STAND CONDITIONS

(Refer to "Regeneration Method")

		Regeneration Method	GENERAL CHARACTERISTICS OF EACH METHOD AND INTERMEDIATE TREATMENTS
		Patch	Stand is of harvestable size and savable understory is absent. Cutting unit boundaries are dictated by stand boundaries or other considerations where stand boundaries are not identifiable. All trees in unit are cut. Unit is normally regenerated artificially.
	Clearcutting	Strip	Stand is harvestable and savable understory is absent. Most appropriate for large, even-aged stands of true fir. Strips are long and normally not over 1 1/2 times the average height of the stand in width, in contouring shapes. All trees are cut. Unit is normally naturally regenerated.
Even-aged Management	Shelterwood	Preparatory Step	Overstory is well stocked and is of harvestable size, savable understory is absent. Regeneration not immediately scheduled. Stand needs to have wind firmness and seed producing ability improved before seed cut is made.
		Seed Step	Salvable understory is not present or unsatisfactory. Sufficient suitable seed trees must be left after harvest to provide shade for new seedlings. All trees other than shelter trees are cut. Unit usually regenerated naturally.
		Removal Step	Timber stands normally consist of an adequately stocked savable understory with sheltering overstory. All overstory trees are cut. Some additional regeneration may follow the timber operation.
	Seed Tree	Seed Tree Step	Overstory is harvestable and savable understory is absent. Suitable seed trees are left after harvest. Aside from scattered seed trees, cutover areas may be similar to clearcut in appearance. Unit is naturally regenerated.
		Seed Tree Removal Step	Timber stands consist of an adequately stocked savable understory with an overstory of scattered seed trees.
Uneven-aged Management	Selection		Stands are uneven-aged or converted to uneven-aged condition. Some trees in all size classes are generally cut. Regeneration is usually obtained naturally. Shade tolerant trees are usually harvested individually and intolerant trees in small groups. Best suitable to economic conditions which make possible frequent entry into stand for small volumes, ground cover and vegetation conditions that will tolerate repeated logging, to maintain control of the site, and when natural regeneration is likely. An intensive road system is normally necessary.
	Intermediate Treatments
	Commercial Thinning		It is the adjustment of stocking prior to harvest at rotation age. The overstory consists of young growth-type trees. Understory may or may not be present.
	Sanitation-salvage		To be used in the cutting and removal of only those trees that are dead, dying or deteriorating because of damage from fire, wind, insects, disease, flood, or other injurious agents, and to prevent the spread of insects or diseases.
	Special		These methods are used to achieve land management objectives not necessarily associated with regeneration or stand tending.
