Attempts to correlate ray tissue as a percentage of total wood volume with sap-sugar concentrations of sugar maple progenies were unsuccessful. These results raise doubts about our ability to use a relatively constant value such as ray-tissue volume in a selection program designed to increase the sap-sugar concentration of sugar maple seedlings.

A statistical report and analysis of the timberland enrolled in the Vermont Use Value Appraisal (UVA) property tax program. The study was conducted using data collected in the fourth forest survey of Vermont (1983). Estimates are presented on land area, timber volumes, tree quality, numbers of live trees, and biomass for timberland enrolled in the UVA program and for all other timberland at the State and geographic unit level. Characteristics of the tirnberland in the program are compared with those of all other tirnberland.

To properly classify or grade logs or trees, one must be able to correctly identify defect indicators and assess the effect of the underlying defect on possible end products. This guide assists the individual in identifying the surface defect indicator and also shows the progressive stages of the defect throughout its development for white oak. It illustrates and describes nine types of external defect indicators and associated defects that are particularly difficult to evaluate.

Estimates of management costs on New York's wildlife management areas indicate that human management is more costly than habitat management. Agricultural agreements and timber sales make a major contribution to habitat inhancement, and a wide variety of wildlife species benefit.

Precommercial thinning was done in a 12-year-old Appalachian hardwood sapling stand in West Virginia. Two crop-tree release techniques were used--crown touching and crown touching plus 5 feet. Results indicated that both treatments significantly increased 5-year d.b.h. growth for released yellow-poplar and black cherry crop trees. Although there was a major increase in d.b.h. growth, caution is suggested when using the crown-touching plus 5 feet treatment as butt-log quality response was not conclusive. Releasing crop trees with the crown-touching approach seems appropriate in sapling...

State-owned wildlife management areas play an important role in enhancing wildlife populations and providing opportunities for wildlife-related recreational activities. In the six New England States there are 271 wildlife management areas with a total area exceeding 268,000 acres. A variety of wildlife species benefit from habitat improvement activities on these areas.

A statistical analytical report on a mail canvass of private timberland owners in New Hampshire. The study was conducted in conjunction with the forest survey of New Hampshire by the USDA Forest Service. It discusses forest-land owner characteristics, attitudes, and intentions of owners regarding reasons for owning, recreational use, timber management, and timber harvesting.

A statistical report on the third forest survey of Delaware (1986). Findings are displayed in 65 tables containing estimates of forest area, number of trees, timber volume, tree biomass, and timber products output. Data are presented at two levels: state and county.

A statistical report on the forest wildlife habitat survey of Maryland and Delaware (1986). Findings are displayed in 11 8 tables covering forest area, landscape pattern, mast potential, standing dead and cavity trees; and understory woody-stemmed vegetation. Data are presented at county and/or unit and state levels of resolution.

This annual report contains 1987 information compiled from a canvass of all pulpmills that use pulpwood produced in the 14 Northeastern States. In 1987, total production reached 9,387,700 cords, an increase of 5 percent since 1986. Roundwood production was 6,796,700 cords whereas pulpwood from residues was 2,591,000 cords. Each of these increased from the previous year, by 3 and 10 percent, respectively. The receipts of pulpwood at mills in the region were 9,894,400 cords.
