Effects of stand density on site index in thinned stands of Douglas-fir in the Pacific Northwest

Zumrawi, Abdel Azim M. A.

Abstract:

In site index studies, the hypothesis that height growth of most conifers is independent of stand density is commonly accepted. However, some studies have shown height growth to be influenced by density particularly on medium to poor sites. In this study two locations representing a high quality site (Hoskins area,...

Growth growing-stock relationships in young Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco)

Creator:

Sales Luis, Jaime Fernando

Abstract:

In the thinning theory, the hypothesis that the stand growth is unaffected by the density over a broad range of densities is generally accepted today. In this study three different measures of stand density were used in basal area growth and volume growth multiple regressions in even-aged managed stands, searching...
