FIREFIGHTS AND FUEL MANAGEMENT: A NESTED ROTATION MODEL FOR WILDFIRE RISK MITIGATION [PDF]

open access: yes
Scientists and policymakers are increasingly aware that wildfire management efforts should be broadened beyond the century-long emphasis on suppression to include more effective efforts at fuel management.

Timber value growth rates in New England

open access: yes, 1990
Rates of growth in the value of standing timber can vary greatly from stand to stand and from tree to tree. In Maine, the compound annual rate of change in stand value between the two most recent forest inventories ranged from -12 to +43 percent. Faced with this kind of variation, forest managers can use help in determining financial rates of return ...

Deriving the Charring Rate of a Wood Fibre Insulation Board by Exposure to the ISO 834 Standard Fire

open access: yesFire and Materials, EarlyView.
ABSTRACT Wood fibre insulation boards (WFIB) are widely used combustible building materials, commonly applied in energy‐efficient construction for their thermal and hygric performance. The present study investigates the behaviour of the most common type of wood fibre insulation when exposed to the ISO 834 standard fire.

Reduction of timber value from damaged spruce stands after their dieback

open access: yesJournal of Forest Science, 2002
The paper presents a method for the derivation of total timber production and of increments in value units, particularly in net financial yield for spruce stands damaged by crown defoliation after their dieback.

IMPLICATIONS OF A MARKET FOR CARBON ON TIMBER AND NON-TIMBER VALUES IN AN UNCERTAIN WORLD [PDF]

open access: yes
Despite considerable interest in the potential for forests to sequester carbon, the impact of carbon management on the provision of timber and non-timber resources has received relatively little attention in the literature.

Multiple-criteria stem bucking (Picea abies L. Karst.) for maximizing monetary value of timber trade [PDF]

open access: yes, 2018
In this study, timber trade scenarios are considered in a wood procurement region of Finland. This multiple objective decision-making situation includes the timber purchase from forest owners and the lumber sales from sawmill to abroad.

Char Layer Thickness Evolution During Structural Timber Fire Experiment and Final Density Profile

open access: yesFire and Materials, EarlyView.
ABSTRACT This paper evaluates several non‐destructive experimental methods for determining the char layer thickness and its density profile in structural timber samples exposed to standard ISO 834 fire curve experiments. Microwave echo pulse, ultrasonic echo pulse, X‐ray computed tomography, and resistance drilling were evaluated.

Economic Evaluation of Biotechnological Progress: The effect of changing management behavior [PDF]

open access: yes
The paper assesses the welfare effects of biotechnological progress, as exemplified by tree improvements, using a partial equilibrium model. Timber demand is assumed to be stochastic and the distributions of the coefficients of the demand function are ...
