Contains 47 abstracts and papers of oral and poster presentations on gypsy moth biology, ecology, impacts, and management presented at the annual U.S. Department of Agriculture lnteragency Gypsy Moth Research Forum.

A list of publications by Northeastern Research Station scientists and cooperators in 1996 and 1997.

A collection of 3,487 fully described, kiln-dried red oak boards totaling 20,021 board feet. The boards, which are straight or contain no more than ? inch of crook, are FAS, FAS ONE FACE (F1F), Selects, No. 1 Common, No. 2A Common, or No. 3A common. The boards were graded with the UGRS (Ultimate Grading and Remanufacturing System) computer program. After the grade was determined, the maximum grading surface in the maximum number of grading cuttings was determined to allow studies of quality within lumber grades. Written for researchers and industry decision makers who may have only a...

Contains information about carbon storage in the vegetation, soils, and peatlands of Russia. Estimates of carbon storage in forests are derived from statistical data from the 1988 national forest inventory of Russia and from other sources. Methods are presented for converting data on timber stock into phytomass of tree stands, and for estimating carbon storage in forest soils and peatlands in Russia's administrative territories and natural ecoregions. Also included is information on the timber stock of Russia's primary tree species and phytomass of forest vegetation, mortmass, and peat.

A fully mapped plot design is compared to three alternative designs using data collected for the recent inventory of Maine's forest resources. Like the fully mapped design, one alternative eliminates the bias of previous procedures, and should be less costly and more consistent. There was little difference in volume and area estimates or in sampling errors among the four procedures.

The user's manual describes the use of the NEWILD computer program. NEWILD is software developed by the U.S. Department of Agriculture, Northeastern Research Station as part of the NED project, and ongoing effort to develop software tools to support Ecosystem Management decision making. NEWILD can be used to determine which of the 338 species of vertebrates in New England may be found in particular habitats, or which habitats are preferred or utilized by a particular species of wildlife. The object of this program is to assist in the access and evaluation of the information presented in...

Contents cover recreation; protected areas and social science; water based recreation management studies; forest recreation management studies; outdoor recreation management studies; estimation of economic impact of recreation and tourism; place meaning and attachment; tourism studies; nature-based tourism planning and development; park and customer management; values; historic, heritage, and cultural tourism; volunteers and partnerships; recreation and natural resource planning; and wildland recreation.

A recently completed forest inventory and two woodland owner surveys have given us insight about the owners of private forest lands in Virginia. There is increasing parcelization of forested lands and an increase in the number of nonindustrial private (NIPF) landowners in Virginia. More than half of the private owners have harvested timber from their holdings at some time in the past, and they control three-quarters of the private forests. Owners have a positive attitude toward timber cutting at a time when there is greater demand for products from the forest. In terms of decision making,...

The Ultimate Grading and Remanufacturing System (UGRS) is the latest generation of advanced computer programs for lumber grading. It is designed to be a training and research tool that allows grading of lumber according to 1998 NHLA rules and remanufacturing for maximum dollar value. A 32-bit application that runs under all Microsoft Windows operating systems, UGRS provides a sophisticated graphical user interfaces that shows the board and includes all defects and cuttings, grading information, the remanufactured board, and final results. Potential application include online evaluation of...

This bibliography contains 1185 references to literature on the gypsy moth published from 1837 to 1991 in the territory occupied by the former U.S.S.R. The bibliography is designed to assist researchers within and outside the former U.S.S.R. to identify, locate, and correctly cite the original Russian or Ukrainian references in English. The bibliography contains publications on gypsy moth ecology, physiology, biochemistry, distribution, behavior, and control. The bibliography also presents indices of key words and natural enemies are cross-referenced to the citations. Introductory remarks...
