Development of a hybrid modeling framework for intensively managed Douglas-fir plantations in the Pacific Northwest

Creator:

Weiskittel, Aaron R.

Abstract:

Forest growth models in the Pacific Northwest are predominantly empirical. Predictions of yield under alternative silvicultural regimes cannot rely completely on field trials; yet empirical growth models are often inadequate for extrapolating untested regimes and genotypes. The limitations of current models include (1) long time-steps (e.g. 5-10 years); (2) insufficient...

Exploration of statistical methods for synthesizing the effects of variable-retention harvesting on multiple taxa

Creator:

Lam, Tzeng Yih

Abstract:

Variable-retention harvesting was proposed to reduce loss of biodiversity and ecosystem processes associated with late-seral Douglas-fir (Pseudotsuga menziesii) forests in the Pacific Northwest. The Demonstration of Ecosystem Management Options experiment was established to test this hypothesis. Analysis presents various challenges to drawing statistical inferences about treatment effects. This dissertation explored...
