Abstract
This thesis analyzes the growth of red fir (Abies magnifica) and California white fir (Abies concolor var. lowiana) in three different sites in California and creates an individual-tree, distance-independent growth simulator. The first chapter of this thesis is a literature review discussing the issues facing the forests composed of these montane true fir in California and the forest growth simulators in common use. The second chapter uses AICc model comparison to determine which models for each species best predicts growth of individual trees in terms of basal area increment (BAI). The third chapter of this thesis uses these individual-tree growth models to create a simulator from an Excel workbook to predict how long treatments would persist in uneven-aged, red and white fir composed stands. Twelve hypothetical stands were created and treated in order to illustrate treatment persistence. Sequoia National Forest (SNF) had shorter treatment persistences than similar Klamath National Forest and Tahoe National Forest (TNF) scenarios. Red fir dominated stands had shorter treatment persistences than similar white fir dominated scenarios. More moist stands had shorter treatment persistences than drier stands.
