Thinning effects on stand and tree growth : different perspectives on same old questions

Creator:

Romero Castaño, Pablo

Abstract:

The search for the stand density that optimizes growth and hence generates the maximum amount of wood is one of the philosopher’s stone in modern forestry. Since scientific methods were applied to forestry, numerous generations of foresters have studied the relations between stocking density and growth, obtaining diverse results and...

Impact of Climate and Disturbance on the Formation of Earlywood and Latewood in Douglas-fir at the Salal Fields Study Site

Creator:

Gourley, Derek M. F.

Abstract:

Wood density is controlled to a large extent by the relative widths of earlywood and latewood in the stem, but the mechanisms controlling these amounts are poorly understood in coastal Douglas-fir. To understand the role of climatic factors, one hundred and thirty-six increment cores were collected and measured from the...

Simulating Effects of Genetic Tree Improvement on Growth and Yield of Coastal Douglas-fir

Creator:

Joo, Sukhyun

Abstract:

Estimating volume gains in genetically improved stands at rotation age is challenging because first-generation progeny tests in Douglas-fir were typically established to measure the relative growth performance of individual trees from open-pollinated parent trees. The overall goal of this dissertation research was to improve growth simulation of genetically improved Douglas-fir...
