Measuring Site Index
Site index (SI) is a measurement commonly used by foresters to describe the productivity of a site. Typically this measurement is used to describe sites growing well-stocked even-aged forests. Site index is the average height of the dominant1 and codominant2 trees on the site, at a given age (base age). Typically, the base age for hardwoods and white pine in Virginia is 50 years, while the base age for loblolly pine is 25 years. For example, a SI of 75, base age 50, means that the average height of the dominant and codominant trees on a site will be 75 feet when they are 50 years old (SI50=75). The higher the SI, the higher the site productivity (trees will grow faster than on a site with a lower SI).

Lean Thinking: Examples and Applications in the Wood Products Industry
Lean thinking is a process focused on increasing the value added to products and services and the reduction of waste. The term “lean,” coined by Womack during one of his visits to the Japanese carmaker Toyota in the early 1980s (Womack and Jones 2003), has become the universally accepted term for increasing value and reducing waste.

Design and Operation of a Solar-Heated Dry Kiln
Lumber is usually dried to a specific moisture content prior to further manufacturing or use. The amount of water in wood is usually expressed as moisture content and can be directly measured or calculated. The moisture content of wood is defined as the ratio of the weight of water in wood to the dry weight of the wood material. While lumber can be air-dried, the humidity in most localities prevents the lumber from reaching the moisture content required for the stability needed for interior use. A dry kiln is required to dry lumber to the necessary final moisture content and does so fairly rapidly. This publication discusses the design and operation of a solar-heated lumber dry kiln that is designed to be inexpensive to construct and simple to operate.

Consider Logging Residue Needs for BMP Implementation When Harvesting Biomass for Energy
Utilization of woody biomass for energy has increased substantially in Virginia. While there are a number of definitions for biomass, woody biomass from forest harvesting operations typically refers to logging residues such as limbs, tops, and other unmerchantable material that would otherwise be left behind on-site after the logging operation is complete. Logging residues are typically chipped and then transported to facilities where they are used for fuel. Biomass harvesting in Virginia most commonly occurs on integrated harvesting operations where roundwood and biomass are harvested and utilized at the same time in a single operation.

Effectiveness of Temporary Stream Crossing Closure Techniques Forest Operations Research Highlights
Protection of water quality is a critical component of forest harvesting operations. Virginia’s silvicultural water quality law (§10.1-1181.1 through 10.1-1181.7) prohibits excessive sedimentation of streams as a result of silvicultural operations. Virginia’s logging businesses invest substantial resources implementing BMPs to protect water quality. The Virginia Department of Forestry (VDOF) is responsible for enforcing this law and inspects all logging operations to ensure protection of water quality.

All-Age Management, Demonstration Woodlot
Many forest owners value their forest for wildlife habitat, recreation, and aesthetics. Given accurate information, many want to manage their woodlot using sound silviculture but clear-cutting as a regeneration method may not be visually acceptable. While a profitable timber harvest is of interest, a visually pleasing residual stand may be more important. To meet this objective, Stand D1 of the SVAREC forests was selected to demonstrate All-Age Management using group selection silviculture and individual thinning of select trees to create four age classes.

Thinning Hardwoods, Demonstration Woodlot
Most forest owners value their forest for wildlife habitat, recreation and aesthetics. Given accurate information, they may manage their woodlot to achieve these and other goals using sound silviculture. Thinning over-stocked woodlots is one silvicultural management tool. Thinning can modify spacing and diversity of species to meet desired goals which may include timber, wildlife, aesthetics and more. Thinning also improves woodlot vigor by removing over-mature, suppressed, defective or weakened trees. To meet theses objective, Stand D2 was selected for a thinning research & demonstration site.
