Book Description
Combines data from eight different forest inventories conducted by the Forest Service and the Bureau of Land Management in California, Oregon and Washington. These inventories were organized and executed by five individual forest inventory programs from two agencies, including the Forest Inventory and Analysis (FIA) program of the Pacific Northwest Research Station (PNWFIA), the Interior West FIA program of the Rocky Mountain Research Station (RMRS), the Continuous Vegetation Survey program of the Pacific Northwest Region (R6, Region 6), the Forest Inventory program of the Pacific Southwest Region (R5, Region 5), and the Natural Resource Inventory program of the Bureau of Land Management (BLMWO, western Oregon districts only). The eight inventories include Western Oregon, Eastern Oregon, California, Western Washington, and Eastern Washington from PNWFIA, California from R5, Oregon and Washington (as one inventory) from R6, and Western Oregon from BLM. Note that PNWFIA collects data on all BLM lands except those in western Oregon; and RMRS collects data on National Forest land in Washington (Kaniksu NF, R1) and California (Toiyabe NF, R4).

Book Description
CalPro is an add-in program developed to work with Microsoft Excel to simulate the growth and management of uneven-aged mixed-conifer stands in California. Its built-in growth model was calibrated from 177 uneven-aged plots on industry and other private lands. Stands are described by the number of trees per acre in each of nineteen 2-inch diameter classes in two species groups, hardwoods and softwoods. CalPro allows managers to predict stand development by year and for many decades from a specific initial state. Users can choose cutting regimes by specifying the interval between harvests (cutting cycle) and a target distribution of trees remaining after harvest. A target distribution can be a reverse-J-shaped distribution or any other desired distribution. Diameter-limit cuts can also be simulated. Tabulated and graphic results show diameter distributions, basal area, volumes, income, net present value, and indices of stand diversity by species and size. This manual documents the program installation and activation, provides suggestions for working with Excel, and gives background information on CalPros growth model. It offers a comprehensive tutorial in the form of two practical examples that explain how to start the program, enter simulation data, execute a simulation, compare simulations, and plot summary statistics.

Book Description
During the 1990s, forest inventories for California, Oregon, and Washington were conducted by different agencies using different methods. The Pacific Northwest Research Station Forest Inventory and Analysis program recently integrated these inventories into a single database. This document briefly describes potential statistical methods for estimating population totals, means, and associated sampling errors for these inventories. Differences in estimates using past methods for periodic inventories compared to estimates from proposed methods for a new annual inventory system were generally minor. This document is intended to be a resource for researchers using the 1990s forest inventory data for these states; examples are included to illustrate issues.

Book Description
Accurate estimates of foliar biomass (FB) are important for quantifying carbon storage in forest ecosystems, but FB is not always reported in regional or national inventories. Foliar biomass also drives key ecological processes in ecosystem models. Published algorithms for estimating FB in conifer species of the Pacific Northwest can yield signifi cantly different results, but have not been rigorously compared for species other than Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco). We compared five algorithms for estimating FB for seven common coniferous species in the Pacific Northwest. Algorithms based on diameter at breast height (DBH), or on DBH and height, consistently yield higher estimates of FB than algorithms based on sapwood area. At the tree level, differences between algorithms increased with increasing DBH for all species, but their order and magnitude differed by species. At the stand level, differences among algorithms were muted by the mix of species and diameter classes that contributed to total FB of stands of different seral stages and species composition. Significant differences among estimates of FB from different algorithms show the need for consistent methods for estimating FB for carbon accounting, tests of the sensitivity of ecosystem models to these differences, and more field observations to compare algorithms.
