Book excerpt: This report highlights key findings from the most recent (20012010) data collected by the Forest Inventory and Analysis program across all forest land in California, updating previously published findings from data collected from 2001 through 2005 (Christensen et al. 2008). We summarize and interpret basic resource information such as forest area, ownership, volume, biomass, and carbon stocks; forest structure and function topics such as biodiversity, forest age, and dead wood; disturbance information such as tree damage, fire, and invasive plants; and tree growth, mortality, and removals for timber products. Consistent sampling across different ownerships and forest management regimes now allow comparisons. The appendices provide details on inventory methods and design and include summary tables of data, with statistical error, for the suite of forest characteristics inventoried.

Available in PDF, EPUB and Kindle. Book excerpt: Of California's almost 100 million ac, about a third are forested (32 million ac). This report, including the accompanying tables, summarizes key findings from the 5,369 Forest Inventory and Analysis (FIA) plots measured in California's forests during the period 2006-2015. Estimates are provided for forest area, ownership, species composition and distribution, size and age classes, volume, biomass, carbon, dead and downed wood, and understory vegetation. Starting in 2001, plots were measured on a 10-year cycle (10 percent of all plots measured annually). Thus, those plots measured in 2011-2015 represent completion of half of the remeasurement cycle; estimates of growth, mortality, and removals from remeasured plots are also included. The U.S. Forest Service manages about half of California's forested land--48 percent. Fifty-two percent of California's forests is categorized as timberland (unreserved forest land capable of producing ≥20 ft of wood per acre per year) predominantly consisting of the California mixed-conifer type. The most common forest type on the remaining 48 percent was western oak. Mean annual gross growth was 1.99 billion ft/year. Subtracting harvest removals (21 percent of growth values) and mortality (45 percent of growth values) still resulted in a positive net growth of 673 million ft/year. Of some of the commercially important tree species, damage was present in 17 to 27 percent of the trees, including Douglas-fir (17 percent), white fir (27 percent), ponderosa pine (20 percent), and redwood (17 percent). The two most prevalent nonnative species were both grasses--cheatgrass (estimated 277,000 ac of cover) and ripgut brome (234,000 ac). During the 10-year period, the years with the most forested acres with evidence of fire were 2008 and 2015. FIA plots will continue to be measured as stipulated by the 1998 Farm Bill. By the time the next FIA report for California is issued, a complete remeasurement cycle will have been completed.

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.

This book was released on 2012-10-19 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication is based on previous documentation of the nationally standardized Forest Inventory and Analysis database (Hansen and others 1992; Woudenberg and Farrenkopf 1995; Miles and others 2001). Documentation of the structure of the Forest Inventory and Analysis database (FIADB) for Phase 2 data, as well as codes and definitions, is provided. Examples for producing population level estimates are also presented. This database provides a consistent framework for storing forest inventory data across all ownerships for the entire United States. Forest Inventory and Analysis (FIA) is a continuing endeavor mandated by Congress in the Forest and Rangeland Renewable Resources Planning Act of 1974 and the McSweeney-McNary Forest Research Act of 1928. FIA's primary objective is to determine the extent, condition, volume, growth, and depletion of timber on the Nation's forest land. Before 1999, all inventories were conducted on a periodic basis. The passage of the 1998 Farm Bill requires FIA to collect data annually on plots within each State. This kind of up-to-date information is essential to frame realistic forest policies and programs. USDA Forest Service regional research stations are responsible for conducting these inventories and publishing summary reports for individual States. In addition to published reports, the Forest Service provides data collected in each inventory to those interested in further analysis. This report describes a standard format in which data can be obtained. This standard format, referred to as the Forest Inventory and Analysis Database (FIADB) structure, was developed to provide users with as much data as possible in a consistent manner among States. A number of inventories conducted prior to the implementation of the annual inventory are available in the FIADB. However, various data attributes may be empty or the items may have been collected or computed differently. Annual inventories use a common plot design and common data collection procedures nationwide, resulting in greater consistency among FIA work units than earlier inventories. Data field definitions note inconsistencies caused by different sampling designs and processing methods.

Available in PDF, EPUB and Kindle. Book excerpt: Hardwood-dominated temperate forests (mostly in Eastern North America, Europe, North East Asia) provide valuable renewable timber and numerous ecosystem services. Many of these forests have been subjected to harvesting or conversion to agriculture, sometimes over centuries, that have greatly reduced their former extent and diversity. Natural regeneration following harvesting or during post-agricultural succession has often failed to restore these forests adequately. Past harvesting practices and the valuable timber of some species have led to a reduction in their abundance. The loss of apex predators has caused herbivore populations to increase and exert intense browsing pressure on hardwood regeneration, often preventing it. Particularly important are fruit, nut and acorn bearing species, because of their vital role in forest food webs and biodiversity. Restoring hardwood species to natural forests in which they were formerly more abundant will require a number of forest management actions (e.g., resistant hybrids, deer exclosures/protectors, enrichment planting, underplanting, etc.). Similarly, reforesting areas that were once natural forests will also require new silvicultural knowledge. Global warming trends will intensify the need for interventions to maintain the diversity and function of temperate hardwood forests, as well as for increase hardwood reforestation.
