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.

Calibrating Hand-held and Backpack Sprayers for Applying Pesticides

Hand-held and backpack sprayers are inexpensive tools used to apply pesticides on small acreages. Home gardens, yards, small orchards, and Christmas tree plantations are examples of areas that often require pesticide applications to protect them from weeds, insects, and diseases. Effective pest control depends on applying the proper amount of pesticide. This can only be done if the spray equipment is calibrated accurately.

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.

Dealing with Timber Theft

Forestland can provide countless hours of recreational benefits as well as an important source of income. Many landowners take careful steps to ensure that their property is managed to maximize the benefits they receive. However, all of this work can be easily eradicated by one of Virginia’s most dreaded forest pests: timber thieves.

Effectiveness of Skid Trail 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 Depart- ment of Forestry (VDOF) is responsible for enforcing this law and inspects all logging operations to ensure protection of water quality. BMP guidelines offer mul- tiple possible options for practices to minimize erosion and sedimentation and protect water quality. Select- ing the most appropriate BMP will depend on specific site conditions, as well as resources available on-site for implementing BMPs. However, research results on BMP implementation can help guide decisions related to BMP implementation for protecting water quality.

Forest Harvesting in Virginia, Characteristics of Virginia’s Logging Operations

Virginia’s forests are a vital resource, providing multiple benefits for the
commonwealth’s citizens, forest landowners, and the forest industry. More than
15 million acres, nearly two thirds of the state’s is forested. These forests provide
an estimated $23 billion in total economic output, annually, and provide forestry
related jobs to nearly 145,000 (Rephann 2008). Forest harvesting is often a critical
component of forest management1. Logging operations are essential to implementing
forest management plans and providing income to forest landowners. In 2011, more
than 5,900 timber harvests occurred on more than 248,000 acres of Virginia’s
forested land, and net growth continues to exceed the volume harvested (VDOF 2011).

Forest Landowner’s Guide To The Measurement Of Timber And Logs

As a forest landowner interested in selling timber, you are naturally interested in the price you will receive
for your product and how that price is determined. The measurement of standing timber and logs may seem
strange and complicated to you, and it is possible that you may be quoted dramatically different prices based
upon differing estimates of the amount of timber you have and the units of measurement used. Methods of
measuring timber and the units of measurement often differ between buyers, and, as a seller, you should have
an understanding of these methods, the units of measurement, and an idea as to a reasonable price for your
timber.

Galls and Rust made by Mites

Galls are abnormal growths of plant tissue induced by insects and other organisms. Gall-making parasites release growth-regulating chemicals as they feed, causing adjacent plant tissues to form a gall. The parasite then develops within the relative security of the gall. Galls come in an endless variety of forms. Many are strikingly colored or curiously shaped. Each gall-making species causes a gall structurally different from all others. By noting the type of host plant and the structure of the gall, one can identify the gall-making mite without actually seeing it.

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).

Measuring Standing Trees and Logs

Timber may be sold as stumpage (trees before they are cut) or as harvested products (sawlogs, veneer logs, or pulpwood). If trees are sold as harvested products, the sale is customarily based upon measured volume. Trees marketed as stumpage may be sold by boundary, a measured estimate of stand volume, or individual tree measurements.

Standing-tree and log volumes can be measured using a scale stick designed to fit Virginia timber conditions. With it you can measure the diameter of a tree, the number of 16-foot logs or the length of pulpwood in a tree, and the diameter and length of sawlogs. Tables printed on the stick provide for varying board-foot volumes for standing trees and for sawlogs of varying lengths.

Powell River Project - How to Restore Forests on Surface-mined Land

Most coal-bearing lands in the Appalachian region were forested prior to mining. The region’s forests are predominantly upland oak-hickory and Appalachian mixed hardwoods. These forests provide many benefits to landowners and the public. Solid wood and paper products are perhaps the most tangible benefits, but a predictable flow of high-quality water from forested watersheds into regional streams is another vital benefit provided by the region’s forests. Forests also fix carbon from the atmosphere, provide wildlife food and cover, and provide recreational opportunities and an aesthetically pleasing environment.

The Role of Logging Business Owners in Forest Certification
Many forest products companies and landowners participate in forest certification programs. Forest certification programs set standards for sustainable forest management and verify that they are being met. Certification programs can demonstrate to consumers that certified forest products come from trees that were grown and harvested sustainably. Participants in certification programs commit to meeting sustainable forest management standards and are periodically audited by a third party to verify compliance.

Thining 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.

To Certify or Not? An Important Question for Virginia’s Family Forest Owners

Family forest owners ask themselves many questions about their properties, such as if and when to cut timber, what types of wildlife to manage for, how to control exotic invasive species, and how to protect water quality. An increasingly common question that forest owners ask is whether they should certify their forests.

This publication can help forest owners determine if certification is an appropriate option. It defines certification, as well as its benefits and costs, and describes three common certification programs in Virginia. It also covers how family forest owners can begin the certification process, lists sources of additional information, and answers frequently asked questions.

To Clear or Not To Clear -- That Is the Question

There are several reasons why someone might want to clear woodland. Pasture for livestock, space for horseback riding, creating a vista, making space for a garden, increasing lawn size, or establishing a field for hay or other crops are but a few. Regardless of the reason, it is important to carefully evaluate all options and thoroughly understand the ramifications.

Tree Crops For Marginal Farmland -- Christmas Trees

This publication describes the most effective practices used to grow Christmas trees in the southern United States and the cost of those practices. It includes a financial analysis with typical costs and expected returns.

Only eastern white pine and Virginia pines are discussed in this guide. But other species, such as Scotch pine and Fraser fir, also can be grown profitably in some locations in the South. To use this publication to best advantage, read it straight through. Take special note of the cultural practices described and their estimated costs. Think about potential markets for the harvest. Read how to evaluate your potential investment, and think about the other benefits of tree crops. Read the case studies to get a better idea of how these investments can be evaluated. To conduct a financial analysis of your own situation, carefully estimate all the production costs, then take your estimates to the local Extension agent or farm management agent for assistance.

Tree Crops for Marginal Farmland: Loblolly Pine

The Tree Crops for Marginal Farmland Project seeks to provide farmers with basic information about grow­ing and marketing tree crops. Tree crops have many advantages for farmers with marginal or unused land. The cost of inputs is relatively low, economic returns may be quite competitive with alternatives, and there are important environmental benefits.

There are five introductory guides in this series, and each has an accompanying videotape. They provide information on a specific tree crop which can be grown on small or medium-sized tracts of marginal or unused farmland. All these crops are common to areas of the southeastern United States, but their economic poten­tial should be investigated by farmers.

Trees and Shrubs for Acid Soils

The trees and shrubs on your new home site are growing poorly, so you take samples to the Extension office and the agent suggests a soil test. Test results show that your soil has a pH of 4.5, which is rated as strongly acid. The agent suggests you either take corrective action to raise the pH or grow different plants.

Trees and Shrubs for Overhead Utility Easements

Trees are valuable assets in commercial, private, and public landscapes. Trees add aesthetic beauty, modify and enhance the environment, serve architectural and engineering functions, and increase property and community economic values. These same trees that enhance landscapes, however, are a major challenge for utility companies. Most people have grown accustomed to reliable, uninterrupted electric, telephone and cable service in their homes and offices. Unfortunately, trees are one of the major causes of power outages in areas of overhead utility lines due to direct tree contact with lines, or to trees or tree limbs falling on the lines.

Trees for Parking Lots and Paved Areas

Parking lots and paved areas are essential urban features that tend to be unsightly in their basic form. Municipal ordinances often mandate specific amounts of parking for different types of commercial or residential land use, as well as landscaping for these parking areas. Landscaping in and around parking lots and pavement improves appearance, prevents soil erosion, and reduces carbon dioxide through photosynthesis. Planted areas also reduce storm water drainage problems, reduce the detrimental effects of wind and noise, and enhance human comfort by providing heat-reducing shade.
