L USDA United states Forest Statistics ^^^^ Departmentof Agriculture New Hampshire: for A99.9 F7622Uf 1983 and 1997 Resource Bulletin NE-146 Thomas Frieswyk Widmann Richard Abstract A statistical report on the fifth forest inventory of New Hampshire conducted in 1996-98 by the Forest Inventory and Analysis Unit of the Northeastern Research Station. Statistics for forest area, numbers of trees, tree biomass, timber volume, growth, and change are displayed at the state and, where appropriate, the county level. The current inventory indicates that there are approximately 9.0 billion cubic feet of growing-stock volume on 4.5 million acres of timberland in New Hampshire. Foreword The fifth inventory of New Hampshire was directed by John R. Peters, Project Leader of the Forest Inventory and Analysis Unit. David J. Alerich supervised the data collection phase of the inventory. He was assisted by Robert E. Ilgenfritz, Richard A. McCullough, and Lucretia B. Stewart, and Kathryn M. Tillman at unit headquarters in Radnor, PA; and by Edward A. Doane, Brian M. LaPoint, Jason W. Morrison, and Scott H. Tepke, who coordinated the activities of the following members of the data-collection field staff in New Hampshire: Michael A. Baer Robert Goodwin James Morin Joseph Barsky William Groth Seth Partridge Karl J. Benner Michael Haldeman Neil Pederson Gabriel Bolton Edward Harrigan David Pierce Chris W. Brown Jeffery Harriman Andrew Reed Lynn D. Brown Mary Honor Steven Schacht Erik Brischler John Hoyt Daniel Schultz Colin Burgess Keith G. Kanoti Jerome Scott Allison M.

Doug Griffith, Richard Goren and Michael Kazimer assisted in data entry and data management. JB Cullen and Worthen Muzzey, along with other members of the New Hampshire Division of Forests and Lands, collected and compiled data on public ownership and assisted in reviewing this document for accuracy. Steve Mongan of LandVest Inc. also assisted in reviewing this document. Vickie M. Sharon was responsible for administrative and secretarial services. The Forest Inventory and Analysis Unit thanks the landowners of New Hampshire and the New Hampshire Division of Forests and Lands fortheir cooperation and assistance during this inventory.
