Book Description
Excerpt from Natural Reproduction of Grand Fir and Mountain Hemlock After Shelterwood Cutting in Central Oregon Recognizing that shade - tolerant Species found in the fir - hemlock type might regenerate better after partial cutting, the Deschutes National Forest began using the shelterwood method in 1971. This paper reports the natural regeneration of grand fir (abies grandis (dougl.) Lindl. And mountain hemlock (tsuga mertensiana (bong.) Carr.) following a good seed year in response to variations in density of the residual stand. 2. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

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.
