Book Description
Shelterwood cuttings on Swain Mountain Experimental Forest were measured to determine performance six to eight years after the shelterwood cutting and before shelterwood removal. Use of appropriate selecting criteria minimized windthrow of seed trees. Regeneration remained red fir, even where the major seed source was white fir. Density of seed trees may affect seedling growth only after the fourth year. Adequate regeneration can be attained and maintained at 25 trees per hectare (10/acre). In addition, the total number of seedlings produced each year was apparently not related to cone production in nearby stands.
