Abstract Fifty of Idaho's forest resource managers were queried about their outlook for sawtimber harvests and issues impacting future harvest levels. Identical questionnaires were sent to managers representing national forests, other public lands, forest industry, and nonindustrial private lands. Managers were first asked to estimate the impacts of 12 specific issues on past and future harvest levels, and then to provide estimates of future harvest levels for the lands directly under their control or jurisdiction. Managers expected sawtimber harvests in Idaho to decline through the year 2000. Idaho harvest levels between 1994 and 1996 were expected to fall 4.6% from average levels in the base period of 1991-1993, with further declines of 14.6% expected in 1997-2000. Across all ownerships, the most significant issues expected to affect harvest levels in Idaho are threatened, endangered, and sensitive species; cumulative impacts; and new forestry techniques. West.

Long Term Trend

Abstract Projections of eastern Oregon private sawtimber harvest are developed using a market model linked to a subplot level projection of growth and inventory. The “base” projection envisions nearly a 50% drop in forest industry harvest relative to recent historical levels, while nonindustrial private forestland harvest remains roughly stable. In this scenario the region would lose nearly one-third of its remaining lumber mills and processing capacity within the first 30 years of the projection. Log prices would show little long-term trend. Simulations of two hypothetical public policies show the impacts of changes in public harvest and the private land base. In a case of expanded riparian protection, which reduces the harvestable private land base by about 11%, private harvest falls by roughly 18% between 2003 and 2033. Large harvest reductions are projected on industrial lands because of limited merchantable inventories. A restoration thinning program on public lands that raises public harvest by 40 million board feet per year over 20 years, sustains recent mill numbers for the next 25 years (although total harvest continues to decline). Substitution of public harvest for private harvest would enable continuation of a higher private cut for several years after the thinning program has ended.

Abstract The 1985 southern pine beetle (SPB) epidemic in Texas was the worst in the state's history, resulting in a loss of almost 810 million board feet (mmbf) of timber. National forestlands experienced five times more damage per acre than private lands in 1985. The Sam Houston National Forest and three units of the Big Thicket National Preserve were worst hit, with almost 16 and 10 SPB spots per 1,000 ac, respectively. Private lands located near public lands experienced higher SPB spot densities than on other private lands. Examination of factors influencing SPB outbreak intensity—including stand structure, direct SPB control measures, and the overall aggressiveness of pest control management—suggest early and aggressive mechanical control on public lands to minimize losses on nearby private lands as a short-term strategy. Further suggestions include spatial considerations in hazard rating systems. South. J. Appl. For. 15(3):145-153.

The Chapman-Richards growth function is used to model jack pine (Pinus banksiana Lamb.) tree height-diameter relationships at provincial, regional, and ecoregional levels. The results suggest that the tree height-diameter relationships of jack pine are significantly different among the geographic regions of Ontario, depending on local climatic, soil, and ecological conditions. In light of this study, the provincial and regional height-diameter models are not appropriate for predicting tree heights at the ecoregional level. Further, applying a specific ecoregional model to other ecoregions will also result in significant biases for predicting local tree heights. The ecoregion-based height-diameter models developed in this study may provide more accurate information on tree growth and development to forest resource managers and planners.

Species Richness And Abundance

Abstract Conservation efforts on private lands are important for biodiversity conservation. On private lands in South Carolina, in the southeastern United States, forestry management practices (prescribed burning, thinning, herbicide application) are used to improve upland pine habitat for wildlife and timber harvest and are incentivized through U.S. Department of Agriculture Farm Bill cost-share programs. Because many forest-dependent avian species have habitat requirements created primarily through forest management, data are needed on the effectiveness of these management activities. We studied privately owned loblolly pine (Pinus taeda) stands in the South Carolina Piedmont region. Our objective was to understand how management practices influence avian species richness and abundance at local (forest stand) and landscape levels in relatively small stands (average ~28 ha). We surveyed 49 forest stands during 2 bird breeding seasons with traditional point counts and vegetation surveys. We evaluated the effects of management on pine stand characteristics, avian species richness, and abundance of state-designated bird species of concern. Repeated burning and thinning shifted stand conditions to open pine woodlands with reduced basal area and herbaceous understories. Stands with lower basal area supported greater avian species richness. Some species increased in abundance in response to active management (e.g., Brown-headed Nuthatch [Sitta pusilla] and Indigo Bunting [Passerina cyanea]), but relationships varied. Some species responded positively to increases in forest quantity at a landscape scale (1–5 km; e.g., Northern Bobwhite [Colinus virginianus]). We found species-rich avian communities and species of conservation concern on working timber lands, indicating that incentivized forest management on private lands can provide valuable habitat for wildlife.

Major Factors

Impacts on the understory of a balsam fir (Abiesbalsamea (L.) Mill.) – paper birch (Betuiapapyrifera Marsh.) stand, caused by winter and spring full-tree logging and by winter tree-length logging which was followed by summer burning, were monitored for two growing seasons after overstory harvest. New species invaded full-tree logging sites, while compositional changes on the burned area were due primarily to the disappearance of species. Prescribed burning on the tree-length logging area prevented the quick increase in density of woody species that occurred on full-tree harvested sites. However, understory production increased on all sites, and by the end of the second season aboveground biomass was 3847, 4516, and 2604 kg/ha on the winter full-tree, spring full-tree, and winter tree-length plus burning sites, respectively, compared with 942 kg/ha on the uncut control.The major factors causing differences were prescribed burning and snow cover during harvest operations. Since our results concur with previous findings and appear predictable, resource managers can choose the technique best suited to specific objectives. However, no matter which system is used, the same core species will persist afterward, and if succession is allowed to continue, an understory will develop similar to that existing before harvest.

Abstract The North East State Foresters Association (NEFA) commissioned a study that resulted in the publication of a report titled, “A Forest Resource Model of the States of New York, Vermont, New Hampshire, and Maine.” In this article we used the integrated NEFA computer simulation framework to go beyond the reported results and further explore the effects on the forest resource in terms of timber harvest, inventory, and price under various market and demand assumptions. Five scenarios were run through the integrated SRTS-ATLAS model to project long-run effects on timber inventory (growing stock) and price. Besides reflecting differing assumptions about demand and supply, these scenarios defined different markets, thus affecting how the wood harvest was allowed to move across the region in response to demand. Regionally, at the end of the 50 yr projection period, cubic-foot growth and harvest were approximately in balance in the Reference Case, the scenario that we felt was most likely. Initial inventory on all timberland was 66.7 billion ft3. By 2050, inventory volume increased 13% to 75.4 billion ft3. Net growth declined over the 50 yr period from 35.3 to 32.1 ft3 ac-1 yr-1, while harvest increased from 26.6 to 31.9 ft3 ac-1 yr-1. Regional real price increased approximately 1.1% yr-1 over the period. Changes in the resource situation in one state affect the situation in the other states. There is a mutual dependence in markets that policy makers need to recognize. The integration of a market module into the NEFA modeling process added the interplay of market forces and improved upon the policy information available from the model.
