“…88). Estimates from the 1978 and 1989 periodic inventories are not directly comparable to the results of the annual inventory because they include removals attributed to land-use change and are limited to removals from timberland (Alerich 1993, Considine andPowell 1980). Removal estimates are not available for 2004 due to the inconsistencies with the 1989 periodic inventory.…”

This report summarizes the third cycle of annualized inventory of Pennsylvania with field data collected from 2009 through 2014. Pennsylvania has 16.9 million acres of forest land dominated by sawtimber stands of oak/hickory and maple/beech/birch forest-type groups. Volumes continue to increase as the forests age with an average of 2,244 cubic feet per acre on timberland. Sawtimber volume has risen 24 percent in 10 years to 115 billion board feet. Net growth outpaced removals by a ratio of 2.4:1 on timberland. Additional information on land-use change, fragmentation, ownership, forest composition, structure and age distribution, carbon stocks, regeneration, invasive plants, insect pests, and wood products is also presented. Sets of supplemental tables are available online at https://doi.org/10.2737/NRS-RB-111 and contain: 1) tables that summarize quality assurance and 2) a core set of tabular estimates for a variety of forest resources. AcknowledgmentsThe authors would like to thank those who contributed to this assessment of Pennsylvania's forest resources. The dedicated and vital data collection staff who took the measurements upon which this analysis is based are:

“…This information is used by policy makers, resource managers, researchers, and the general public to better understand forest resources and to make more informed decisions about its fate. Periodic forest inventories of Pennsylvania were completed in 1955, 1965, 1978, and 1989(Ferguson 1955, Ferguson 1968, Considine and Powell 1980, and Alerich 1993, respectively, and Widmann 1995. In those earlier inventories, FIA measured trees only on timberland plots and did not report volumes on forest land.…”

The second full annual inventory of Pennsylvania's forests reports a stable base of 16.7 million acres of forest land. Northern hardwoods and mixed-oak forest-type groups account for 54 and 32 percent of the forest land, respectively. The State's forest land averages about 61 dry tons of wood per acre and almost 6,500 board feet (International ¼-inch rule) per acre on timberland. The ratio of average annual net growth-to-removals for growing-stock trees on timberland was about 2:1. Additional information is presented on forest land use, forest resources, forest sustainability, forest health (including regeneration), and timber products. Detailed information on forest inventory methods and data quality estimates are included in a DVD at the back of the report. Tables of population estimates and a glossary are also included.

“…The USDA Forest Service's, Forest Inventory and Analysis (FIA) program has been conducting forest inventories in Pennsylvania since the 1950's. Periodic reports on the status of and changes in forest conditions were completed for 1955 (Ferguson 1955), 1965 (Ferguson 1968), 1978 (Considine and Powell 1980), and 1989 (Alerich 1993).…”

In 2000. the USDA Forest Service's Forest Inventory and Analysis (FIA) program implemented a new system for inventory and monitoring Pennsylvania's forest resources. The most salient feature of the new inventory process will be a nearly threefold improvement in timeliness. This report summarizes the results of the first 2 years of annual inventory measurements. The area of forest land in Pennsylvania has remained stable since a previous inventory in 1989. The Keystone State's forests continue to mature as larger trees and an increase in inventory volume were recorded. A separate study of tree seedlings revealed a general lack of regeneration in one-third to one-half of stands in which regeneration should be adequate.
