Describes factors affecting the availability of fuelwood from nonindustrial private forests (NIPF) in the Northeast. The availability of market fuelwood depends heavily on tract size. The demand for land to supply the expanding urban fringe may result in a lower supply of market wood but also in more wood being cut to satisfy the owner's need for wood. NIPF owners in the Northeast might be persuaded to sell firewood to a regional market, but this supply would not meet the region's total energy needs for more than several years. However, fuelwood could become an important energy supplement...

This annual report contains 1990 information compiled from a canvass of all pulpmills that use pulpwood produced in the 14 Northeastern states. Contains data about pulpwood production and consumption from roundwood by county and species groups, and pulpwood chip production from manufacturing residues by state. Comparisons are made with the previous year's data. Trends in pulpwood production are shown graphically.

The USDA Forest Service along with various cooperators has initiated Forest Health Monitoring (FHM) in New England to assess the condition and stressors of the region's forests, to analyze changes in these data over time, and to identify any relationships between forest condition and stressors. A major component of FHM in New England is 263 permanent plots located across the region on which growth efficiency, foliar condition and nutrition, soil nutrition, and landscape characteristics will be measured and reported annually. This publication describes the forest resources of New England...

The USDA Forest Service, in cooperation with the U.S. Environmental Protection Agency and the New England State Forestry Agencies initiated field sampling for the Forest Health Monitoring program in 1990. Two hundred and sixty-three permanent sample plots were established. Measurements were taken to characterize the physical conditions of the plots. This publication reports results of the first-year measurements of tree crown condition, tree damage, and bioindicator plants. The publication also reports the status of major forest stressors during 1990, including forest insects and pathogens,...

Millipedes have not been reported as pests of germinating acorns. Studies in Pennsylvania on the impact of insects on northern red (Quercus rubra L. seedling establishment revealed that the millipede Ptyoiulus impressus (Say) damaged the radicles of germinating acorns. Up to 17 percent of the acorn radicles in areas with heavy acorn crops were damaged in 1'991. Millipede feeding began in late March to early April, several days prior to feeding activity of insects that damage or destroy germinating acorns.

A survey of goose hunters on a limited access area, Dead Creek Goose Management Area, in Vermont, was conducted during the fall of 1987. Respondents appeared well adapted to the structured hunting environment and agreed with most of the special rules and regulations. The current lottery system was favored over "first-come, first-served" and market pricing as alternative marketing systems.

Leaves (1986) from elm hybrids ('Pioneer', 'Homestead', '970') previously fumigated in open-top chambers with ozone or with charcoal-filtered air (CFA) were evaluated for water and nitrogen content or were fed to adult elm leaf beetles (ELB), Xanthogaleruca = (Pyrrhallta) luteola (Muller), to determine host suitability for beetle fecundity and survivorship. ELB females fed ozone-fumigated leaves laid significantly fewer eggs than females fed CFA-fumigated leaves. Leaf nitrogen or water content was unaffected. Hybrid '970' (1988) was fumigated with CFA or with ozone concentrations to...

Describes methods for predicting lithologies present in soils developed on glacial till, and the potential weathering contributions from rock particles >2 mm in diameter. The methods are not quantitative in terms of providing weathering rates, but provide information that can further the understanding of forest nutrient cycles, and possibly assist with decisions about forest harvesting.

Seed fall was measured for 11 years in a 200-year-old stand of sugar maple, yellow birch, and beech in New Hampshire. Yellow birch had 5 good seed years, sugar maple had 3, and beech had none. Viable seed fall of yellow birch began in August and continued through autumn and winter. Most of the viable sugar maple seed fell during a short period in October. Beech seed fall occurred slightly later than sugar maple. Seed losses caused by pollination or fertilization failure, abortion, incomplete development, insects, small mammals, and birds averaged about 213 of the total seed fall, but...

Prediction equations for estimating cycle time were developed for five small tractors studied under various silvicultural treatments and operating conditions. The tractors studied included the Pasquali 933, a Holder A60F, a Forest Ant Forwarder (Skogsman), a Massey-Ferguson, and a Sam4 Minitarus. Skidding costs were estimated based on the cycle-time equations. Using these equations to determine the incremental effect of log size on cost shows that hooking a 30-fP log cost $0.1 03/ft3 while hooking six logs to form a 30-cubic foot turn cost $0.234/ft3, an increase of 127 percent.
