|24 Ways to Kill a Tree||
There is a tremendous diversity of herbaceous perennial plant species being grown for both the retail and landscaping sectors of the industry. Because of the diversity in species grown, there is much more unknown about perennials production than is known. Growth regulation is of particular concern. In production settings, as well as in retail locations, herbaceous perennials grown in pots tend to stretch and become leggy or simply overgrow their pots before their scheduled market date. These plants are less marketable, and harder to maintain. Many growers resort to pruning, which is not only costly in terms of labor, but also delays plant production two to four weeks.

|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.

|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.

|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 and Shrubs that Tolerate Saline Soils and Salt Spray Drift||
Concentrated sodium (Na), a component of salt, can damage plant tissue whether it contacts above or below ground parts. High salinity can reduce plant growth and may even cause plant death. Care should be taken to avoid excessive salt accumulation from any source on tree and shrub roots, leaves or stems. Sites with saline (salty) soils, and those that are exposed to coastal salt spray or paving de-icing materials, present challenges to landscapers and homeowners.

|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.

|Twig Girdler/Twig Pruner||
In the larval stage, both the twig girdler and twig pruner are creamy white in color and up to 2 inches in length. They look like typical roundheaded borers in that their heads and bodies are cylindrical in shape and they have legs that are reduced to very small claws. The adult twig girdler is about 5/8 inch long and has a pair of long antennae. The color is brown with irregular patches of fine gray hairs and the antennae are spines on the segments closest to the head.
