PNW-FIA Publication Alert

November 2004


We would like to announce the availability of a number of publications authored or co-authored by Pacific Northwest Forest Inventory and Analysis (PNW-FIA) researchers and analysts over the last year. These publications describe analysis techniques or models. You can also find these publications on our Web page at

Fire Prediction:

The impact of climate change on wildfire severity: a regional forecast for northern California. 2004. By Jeremy Fried*, Margaret Torn, and Evan Mills. Climatic Change 64: 169-191. This article describes the use of several models to predict fire outcomes, including number of escaped fires, area affected, and return intervals, in the San Francisco Bay area, the Sierra Nevada, and the north coast.

Inventory Analysis Techniques:

A hierarchical linear model for tree height prediction. By Vicente Monleon* 2004. This paper was presented at the Annual Meeting of the American Statistical Association, San Francisco, August 2003.


Inventory: Modeling. 2004. By Tara Barrett* and Jeremy Fried*. In: Encyclopedia of forest science. Elsevier: 426-433. This book chapter discusses the use of modeling in forest inventory applications, such as modeling tree and forest attributes, spatial modeling, and temporal modeling.


Predicting forest attributes in southeast Alaska using artificial neural networks. 2004. By Simon Corne, Stephen Carver, William Kunin, Jack Lennon, and Bill vanHees*. Forest Science 50(2): 259-276. This publication describes prediction of the characteristics of unsurveyed locations between forest inventory sites using artificial neural network (ANN) methods and also evaluates the relative performance of different ANNs.


Estimation procedures for the combined 1990s periodic forest inventories of California, Oregon, and Washington. 2004. By Tara Barrett*. PNW-GTR-597. This publication de4scribes possible statistical methods for estimating population totals, means, and associated sampling errors for inventories that were conducted using different methods.


Proceedings of the Third Annual Forest Inventory and Analysis Symposium, October 17-19, 200, Traverse City, MI. 2003. NC-GTR-230. A number of articles were authored by PNW-FIA researchers including:

A comparison of stratification effectiveness between the national land cover data set and photo interpretation in western Oregon. By Paul Dunham*, Dale Weyermann*, and Dave Azuma*.


Efficiency and precision for estimating timber and non-timber attributes using LandSat-based stratification methods in two-phase sampling in northwest California. By Antti Kaartinen*, Jeremy Fried*, and Paul Dunham*.


A first look at measurement error on FIA plots using blind plots in the Pacific Northwest. By Susanna Melson*, Dave Azuma*, and Jeremy Fried*.



Reproducibility of vegetation cover estimates in south-central Alaska forests. 2003. By Dot Helm and Bert Mead*. Journal of Vegetation Science 14: 33-40. This article reports a comparison of 5 different methods of sampling understory vegetation and 3 statistical methods of evaluating reproducibility.



Potential yield, return, and tree diversity of managed, uneven-aged Douglas-fir stands. 2004. By Rebecca Ralston, Joseph Buongiorno, and Jeremy Fried*. Silva Fennica 38(1):55-70. This journal article describes the effects of different management regimes on uneven-aged Douglas-fir stands in the PNW using WestPro, a simulation model.


Adding Gaussian noise to inaccurate digital elevation models improves spatial fidelity of derived drainage networks. 2004. By Demetrios Gatziolis* and Jeremy Fried*. 2004. Water Resources Research 40. This article describes an economical approach to improving prediction of hydrological models for ephemeral and perennial stream networks.


Non-linear matrix modeling of forest growth with permanent plot data: The case of uneven-aged Douglas-fir stands. 2003. By Rebecca Ralston, Joseph Buongiorno, B. Schulte, and Jeremy Fried*. International Transactions in Operational Research 10:461-482. A growth and yield model for mixed, uneven-aged Douglas-fir and hardwood stands is described; results suggest uneven-aged management can be as productive as even-aged management for Douglas-fir in the PNW.


Modeling the spatially dynamic distribution of humans in the Oregon (USA) coast range. 2003. By Jeff Kline, Dave Azuma*, and Alissa Moses. Landscape Ecology 18: 347-361. Using inventory plot and other data, an empirical model was developed that describes the spatial distribution and rate of change in historic building densities as a function of a gravity index of development pressure, existing building densities, slope, elevation, and existing land use zoning.
