This report details how land cover and urbanization vary within the states of Delaware, Florida, Georgia, Maryland, North Carolina, South Carolina, Virginia, and West Virginia; and the District of Columbia by community (incorporated and census designed places), country subdivision, and country. Specifically this report provides critical urban and community forestry information for each state including human population characteristics and trends, changes in urban and community lands, tree canopy and impervious surface cover characteristics, distribution of land-cover classes, a relative...

The Forest Inventory and Analysis program of the U.S. Forest Service collects vast amounts of filed data to assess the condition and trends the nation's forest resources. A quality assurance program is implemented to assure that data are collected accurately with consistent protocols. A random subset of field plots is chosen to receive an additional, independent measurement by another field crew.

Specifi cally this report provides critical urban and community forestry information for each state including human population characteristics and trends, changes in urban and community lands, tree canopy and impervious surface cover characteristics, distribution of land-cover classes, a relative comparison of urban and community forests among local government types, determination of...

Ice storms occur frequently in northeastern North America. They damage and kill trees, change the structural characteristics of a forest, and may importantly alter the goods and services that owners realize from their land. This literature review summarizes 90 years of relevant information, mainly from fairly short term studies published between 1904 and 2006. It documents ice storm severity and the effects on hardwood branch loss, primarily among upper canopy trees; methods for estimating and classifying hardwood crown damage; and factors infl uencing epicormic branch formation on hardwood...

Describes the structure of the Forest Inventory and Analysis Database (FIADB) 4.0 for phase 3 indicators. The FIADB structure provides a consistent framework for storing forest health monitoring data across all ownerships for the entire United States. These data are available to the public.

Close to 80 percent of the U.S. population lives in urban areas and depends on the essential ecological, economic, and social benefits provided by urban trees and forests. However, the distribution of urban tree cover and the benefits of urban forests very across the Untied States, as do the challenges of sustaining this important resource.

FORCARB2, an updated version of the U.S. FORest CARBon Budget Model (FORCARB), produces estimates of carbon stocks and stock changes for forest ecosystems and forest products at 5-year intervals. FORCARB2 includes a new methodology for carbon in harvested wood products, updated initial inventory data, a revised algorithm for dead wood, and now includes public forest land, reserved forest land, and forest land of low productivity. The model has been used to provide estimates and projections for policyrelated needs, including the Resources Planning Act timber resource assessment and...
