This publication provides an overview of forest resource attributes for New Jersey based on an annual inventory conducted by the Forest Inventory and Analysis (FIA) Program of the U.S. Forest Service, Northern Research Station. These estimates, along with web-posted core tables, will be updated annually. For more information, refer to page 4 of this report.

Provides current and historical information on primary and secondary hardwood products, production, prices, international trade, and employment.

Longleaf pine (Pinus palustris Mill.) was once one of the most ecologically important tree species in the Southern United States. Longleaf pine and its accompanying forest ecosystems covered vast swaths of the Southern United States, spanning an estimated 92 million acres. Although once one of the most extensive forest ecosystems in North America, only a fraction of these longleaf pine forests remain today. Here we present a brief description of longleaf pine ecosystems and their constituent parts, a history of longleaf pine in the South, and the recent historical and current status of...

The annual national technical report of the Forest Health Monitoring Program of the Forest Service, U.S. Department of Agriculture, presents forest health status and trends from a national or multi-State regional perspective using a variety of sources, introduces new techniques for analyzing forest health data, and summarizes results of recently completed Evaluation Monitoring projects funded through the national Forest Health Monitoring program. Landscape pattern assessments are presented for Alaska, Hawaii, and Puerto Rico. Data from detection and monitoring surveys are used to identify...

This study examines the effects of thinning, age, and site quality on aboveground live tree carbon (ATC) (Mg/ha) stocks in upland hardwood forests of mixed-species composition in the southern Appalachian Mountains. In 1974, 80 plots ranging in size from 0.06 to 0.1 ha were established in even-aged, mixed-hardwood forests throughout the southern Appalachians. All trees
2.54 cm dbh within each plot were tagged and measured. Sixty-two plots received a low thinning to a broad range of residual basal areas (BAs) (m²/ha) whereas 18 of the 80 plots remained unthinned and served as controls....

Soil incorporation of postharvest forest floor or logging residues during site preparation increased mineral soil carbon (C) and nitrogen (N) concentration and had a differential effect on early stand growth in a clonal loblolly pine (Pinus taeda L.) plantation. Incorporating 25 Mg ha
1 of forest floor (FF) (C/N ratio  112:1) or 25 (1LR) or 50 (2LR) Mg ha
1 masticated logging residues (C/N ratio  856:1) increased soil C concentration by 24
49% in the top 60 cm of soil compared with that for a nontreated control or a raked (R) treatment where the forest floor (
25 Mg ha
1) was removed....

In the Western US, millions of acres of forestland have lost ecological integrity. These overstocked stands are at significant risk for disease and insect attack, and high risk for catastrophic wildfire. Finding alternative and higher value uses for material thinned from the forests can help pay for mechanical thinning. Three different types of connections for round wood members made of Douglas fir and Lodgepole pine were tested. Results showed that all three types of connections exceeded the anticipated design load. There were, however, significant differences between the ductility and...

This resource bulletin consolidates data from the eighth complete survey of Tennessee’s forest resources which was conducted during the period 2005–09 by the U.S. Department of Agriculture Forest Service, Forest Inventory and Analysis (FIA) program in coordination with the Tennessee Department of Agriculture Division of Forestry. Data on the extent, condition, and classification of forest land and associated timber volumes, as well as growth, removals, and mortality rates are described and interpreted. Data on forest health and forest landowner characteristics are also evaluated. Estimates...

The authors estimate the relationship between trees and three crime aggregates (all crime, violent crime, and property crime) and two individual crimes (burglary and vandalism) in Portland, Oregon. During the study period (2005-2007), 431 crimes were reported at the 2,813 single-family homes in our sample. In general, the authors find that trees in the public right of way are associated with lower crime rates. The relationship between crime and trees on a house’s lot is mixed. Smaller, view-obstructing trees are associated with increased crime, whereas larger trees are associated with...

Field data from randomly located plots in 12 cities in the United States and Canada were used to estimate the proportion of the existing tree population that was planted or occurred via natural regeneration. In addition, two cities (Baltimore and Syracuse) were recently re-sampled to estimate the proportion of newly established trees that were planted. Results for the existing tree populations reveal that, on average, about 1 in 3 trees are planted in cities. Land uses and tree species with the highest proportion of trees planted were residential (74.8 percent of trees planted) and...
