Download or read book CalPro written by Jingjing Liang and published by . This book was released on 2004 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Forest Inventory-based Estimation of Carbon Stocks and Flux in California Forests in 1990 written by Jeremy Steven Fried and published by . This book was released on 2008 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estimates of forest carbon stores and flux for California circa 1990 were modeled from forest inventory data in support of California's legislatively mandated greenhouse gas inventory. Reliable estimates of live-tree carbon stores and flux on timberlands outside of national forest could be calculated from periodic inventory data collected in the 1980s and 1990s; however, estimation of circa 1990 flux on national forests and forests other than timberland was problematic owing to a combination of changing inventory protocols and definitions and the lack of remeasurement data on those land categories. We estimate annual carbon flux on the 7.97 million acres of timberlands outside of national forests (which account for 24 percent of California's forest area and 28 percent of its live tree aboveground biomass) at 2.9 terragrams per year.

Download or read book Estimation Procedures for the Combined 1990s Periodic Forest Inventories of California, Oregon, and Washington written by Tara M. Barrett and published by . This book was released on 2004 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Comparing Algorithms for Estimating Foliar Biomass of Conifers in the Pacific Northwest written by Crystal Lynn Raymond and published by . This book was released on 2013 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2008 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report uses data from a network of forest inventory plots sampled at two points in time, annual aerial insect and disease surveys, and specialized pest damage surveys to quantify the incidence and impact of insects, diseases, and other damaging agents on Oregon's forests. The number and volume of trees damaged or killed by various agents is summarized. Differences in the frequency and severity of damaging agents between various ownership categories and geographic regions of the state are investigated.
