Spatially explicit inter-temporal forest management decision under the risk of fire

Creator:: Konoshima, Masashi
Abstract:: This paper presents a framework for analyzing efficient spatial allocation of forest management efforts - fuel treatment and harvest - under the risk of fire. The framework integrates a fire behavior model and a spatially-explicit stochastic dynamic optimization model. I investigate the effects of spatial interaction across plots during forest...

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...

Conifer, a model of carbon and water flow through a coniferous forest : documentation

Creator:: Coniferous Forest Biome Modeling Group and U.S. International Biological Program. Coniferous Forest Biome
Abstract:: CONIFER simulates water, carbon, and energy dynamics of a coniferous forest. The model consists of 29 nonlinear difference equations. Driving variables include air temperature, dew point temperature, precipitation, solar radiation, and wind speed. Water and energy variables are updated daily; carbon variables are updated weekly. This report contains a detailed...

Sensitivity analysis as "propagation of error" and model validation

Creator:: Overton, W. Scott
Abstract:: Conclusion: The first part of this note deals with problems of propagation of error and the latter part with questions commonly identified as "model validation" questions. It is concluded that all validation questions can be resolved into two parts: (1) strategic aspects, involving logical and inferential structures and (2) tactical...

Modeling the hydrological aspects of the Fern Lake Watershed : annual report 1971

Creator:: Fowler, Charles W. (Charles Winsor), 1941-, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Data collected from the Fern Lake watershed between 1958 and 1971 include measurements of the rate of flow of water into the lake through a single inlet stream. The objective of the work presented here is to develop a model of this flow using the climatological data available from the...

Trophic relation model in aquatic communities sockeye salmon model, Wood River Lakes, Alaska

Creator:: Eggers, Douglas M., Rogers, Donald E., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: The objective of this study is to develop a mathematical model to relate the production of juvenile sockeye salmon in the Wood River Lake system to parent stock size, primary and secondary production, population size of predators and competitors, and abiotic variables.

Diameter growth equations for Douglas-fir and grand fir in the western Willamette Valley of Oregon

Creator:: Zumrawi, Abdel Azim, Hann, David W., and Oregon State University. Forest Research Laboratory
Abstract:: Equations for predicting diameter growth are an essential component of single-tree growth and yield models (Munro 1974). Diameter growth predictions are used to characterize individual-tree development and to project the growth of stand basal area and volume. Both diameter growth and basal area growth have been used as the dependent...
