Economic analysis of integrating spatial concerns into harvest scheduling

Creator:

Yoshimoto, Atsushi

Abstract:

An analytical algorithm to formulate a sparser set of adjacency constraints than the conventional algorithm is proposed. Utilizing matrix algebra applied to an adjacency matrix, constraints are systematically and efficiently derived by the proposed algorithm. The proposed algorithm is proved to provide a true set of adjacency constraints in the...

Dissertation
Modeling crown profile of Douglas-fir in the Western Willamette Valley

Creator:

Mortzheim, Joseph T.

Abstract:

Crown profile was modeled using a system of equations with three components. The first equation predicts the maximum crown width of an open grown tree based on the tree's diameter at breast height. The second equation modifies maximum crown width to represent the largest width of the crown in stand...

Masters Thesis
A multivariate control solution to the mixed species/diameter class thinning and final rotation problem

Creator:

Cousar, Paul K.

Abstract:

The algorithm RLS-PLUS was developed to yield solutions to the multivariate control problem of diameter and species optimization for mixed conifer and hardwood stands. The problem is specified with twenty-five state variables consisting of five species groups with four merchantable diameter classes and one unmerchantable class. This gives twenty diameter...

Masters Thesis
Measuring the economic impact of forests on neighboring properties

Creator:

Kim, Yeon-Su

Abstract:

This thesis investigated the contribution of the forest to neighboring property prices and explored the possible impacts from different neighboring forest characteristics with the hedonic property price model. The quadratic Box-Cox model was applied to choose the proper functional form. The square root model was chosen to be the interpretable...
