|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).

|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.

|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.

|Invasive Exotic Plant Species Identification and Management||
Invasive exotic species are plants that are not native to a given area and have the ability to out-compete indigenous plant species. Invasive exotics are often brought into their non-native surroundings by humans with good intentions.

|Invasive Exotic Plant Species: Autumn Olive (Elaeagnus umbellata)||
Autumn olive was introduced to the U.S. from Japan and China in 1830. It was originally planted for wildlife habitat, shelterbelts, and mine reclamation, but has escaped cultivation. It is dispersed most frequently by birds and other wildlife, which eat the berries.

|Invasive Exotic Plant Species: Ailanthus (Ailanthus altissima)||
Ailanthus, also known as tree-of-heaven and paradise- tree, is a major nuisance to foresters, farmers, and homeowners alike. Its prolific seeding and ability to sprout from roots and stumps and grow quite rapidly just about anywhere make it a serious competitor and threat to native species and cultivated crops. On top of that, ailanthus is allelopathic, producing substances that are toxic to and inhibit the growth of neighboring plants.

|Invasive Exotic Plant Species: Honeysuckle (Lonicera spp.)||
Several species of Asian honeysuckle have been introduced in the United States for their ornamental and wildlife values. Honeysuckle is perhaps the most widespread exotic invasive in the U.S., now found in at least 38 states. The Asian honeysuckle produces abundant seeds which are dispersed by birds and other wildlife. It also spreads by sprouting from its roots. Because it tolerates shade from other plants, it grows in forest understories.

|Characteristics of Common Western Virginia Trees||
Forest management is a complex process. Silviculture—a system in which healthy communities of trees and other vegetation are established and maintained for the benefit of people—uses forest ecology to guide complex management prescriptions that mimic forest disturbances and processes. Silvics—the natural characteristics of trees—play an important role in prescribing effective silviculture.

|So You Want To Sell Timber||
Research into the attitudes and actions of private forest landowners shows that although very few own their forestland for the purpose of producing timber, most will sell timber at least once in their lifetimes. Private forest landowners sell timber for a variety of reasons that range from purely financial to solely for management purposes. Often landowners do not consider selling timber until they have an immediate need for cash. Other times the landowner has planned an immediate commercial thinning with a full timber harvest scheduled in 10 years. Whatever the reason(s) for a timber sale, careful consideration of objectives is paramount.

|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.
