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). |

Twig Girdler/Twig Pruner | These beetles cause very conspicuous damage in late summer. The leaves on large numbers of twigs and branches will be observed to turn brown prematurely. These twigs and branches sometimes fall from trees in great numbers and accumulate. On close examination, the twigs have one of two kinds of damage. Twigs damaged by the twig girdler are cut as neatly as by a knife. The cut end has been gnawed almost straight across with a faint rounding and is slightly roughened by the chewing. The twig girdler is more commonly found on pecan and hickory. The twig pruner causes a slightly different type of cut. The twig will be observed to have a hollowed out space at the cut end filled with sawdust like frass. The twig when split open will have a long tunnel through most of its length. The twig pruner is more commonly found on oak. |

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. |

An Introduction to Growing Christmas Trees in Virginia | Each year many landowners in Virginia consider Christmas
tree farming as an alternative enterprise for their
unused open land. The number of growers in the Commonwealth
is increasing steadily, and currently Virginia
ranks eighth in the nation in Christmas tree production,
with about 1.8 million trees harvested in 1990. |

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. |

Timber Theft in Virginia | 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. |

Understanding the Science Behind Riparian Forest Buffers: Effects on Water Quality | Over a third of our nation’s streams, lakes, and estuaries
are impaired by some form of water pollution (U.S.
E.P.A. 1998). Pollutants can enter surface waters
from point sources, such as single source industrial
discharges and waste-water treatment plants; however,
most pollutants result from nonpoint source pollution
activities, including runoff from agricultural lands,
urban areas, construction and industrial sites, and failed
septic tanks. |

Exotic Invasive Plants | 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. |
Apr 28, 2020 | 420-321 (CNRE-97P) | ||
Invasive 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. |
Jan 8, 2021 | 420-322 (CNRE-128NP) | ||
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. |

Coloring Christmas Trees Before Harvest | As the Christmas tree industry develops in Virginia, the
production of larger quantities of trees places growers in a
more competitive environment. Under conditions of competition,
it becomes necessary for growers to produce the
highest quality trees possible in order to enjoy marketing
success. There are many characteristics of Christmas trees
which are widely considered to be quality factors, but the
most important are shape, needle retention, straightness,
and color. |

Selecting and Managing Trees to Avoid Conflicts with Overhead Utility Lines | Trees can become a dangerous liability when they are planted near utility lines and their mature size leads to conflicts with the utility lines. Trees can damage utility lines, disrupt power delivery, and create hazardous conditions. Utility companies expend significant resources managing tree conflicts through pruning and removal. Despite the potential for these conflicts, property owners often desire trees near utility lines for amenity and privacy. To prevent recurring conflicts with utility lines, trees with compatible mature size should be planted near utility lines. In this publication are recommendations for minimizing tree conflicts with utility lines along with an extensive list of utility line compatible tree species suitable for landscapes in Virginia and the Mid-Atlantic region. |

Periodical Cicada | In Virginia both the 17-and 13-year cicadas damage many ornamental and hardwood trees. Oaks are commonly attacked but the most seriously damaged are newly planted fruit and ornamental trees such as apple, dogwood, peach, hickory, cherry, and pear. Pines and other conifers are not commonly attacked. |

Powell River Project - Growing Christmas Trees on Reclaimed Surface-mined Land | Christmas tree production can be an excellent use for reclaimed mined lands in Virginia. Most species do quite well on mine soils because they are more tolerant of infertile and droughty conditions than agricultural or horticultural crops, yet they do respond to active management. Christmas trees can be harvested within seven to 10 years, while timber crops take much longer to mature. For the person with time to invest, Christmas trees can be an ideal way to put small parcels of reclaimed mined lands to profitable use. Individual growers can conveniently maintain up to 5 acres of trees in their spare time. |

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 Skid Trail Closure Techniques. Forest Operations Research Highlights | Dec 13, 2019 | ANR-109NP | |||
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. |

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. |

Trees and Water | Since at least the late 1800s, scientists and forest managers in the United States have recognized that forests have strong influences on water resources (Hewlett 2003). Today the connections between forests and water are widely reported in the news media, promoted by natural resource agencies, and investigated by specialists such as hydrologists, dendrologists, foresters, forest biologists, and water managers. Tree structures and functions influence at least four major areas of water-resources concerns: (1) water quality, (2) aquatic habitat, (3) water quantity, and (4) the interactions among water, climate, and energy use. This publication provides a basic introduction to Virginia's trees and a foundation for assessing the connections between water and trees. |

Slash Application Cost Estimates for Skid Trail Closure in the Virginia Piedmont | Best management practices (BMPs) were developed after the passage of the Federal Water Pollution Control Act of 1972 to mitigate pollutants and sediment from entering streams. Forest operations are a potential source of sediment to streams surrounding harvest areas. Specifically, roads, skid trails, landings, and stream crossings can cause accelerated erosion due to the soil disturbance caused by logging equipment and exposure of bare soil (Appelboom et al. 2002). Soil erosion can result in decreased productivity, degraded water quality, and increased costs associated with state and federal environmental regulations. |

One-Year Health, Mortality, and Growth in Southeast Virginia of Shortleaf Pine From Three Sources | Restoration of shortleaf pine (Pinus echinata Mill.) in Virginia has become a priority of various state and federal agencies. For shortleaf pine restoration to be successful in Virginia, private lands must be considered because 89 percent of forestland in Virginia is privately owned, and most private landowners are likely to use commercially available seedling sources.
Shortleaf seedlings from commercially available sources in Virginia, Arkansas, and Missouri were planted in two sites in Southeast Virginia to test growth and yield. After one year, height and ground-line diameter were measured and observations were made on health and mortality of the plants. The Virginia seed source was significantly taller than the Arkansas source. At the first site, mortality and disease were low, but at the second site, mortality and poor health were very high, possibly due to soils combined with weather conditions. No significant seed source effects on disease and mortality were found at either site. |

Yellow Poplar Weevil | Rice-shaped holes about 1/16 inches result from adult feeding. Larval feeding
forms mines, usually two per leaf. If they are both on the same side of
midrib, one is extensive, and the other dwarfed. If the insect lays eggs on
opposite sides of the midrib, both mines develop normally. |

Fall Cankerworm | Cankerworms are also known as inchworms, loop worms, and spanworms - this is credited to their distinctive way of moving. In order to travel, a cankerworm must grab leaves or
branches with its front legs and then pull the rest of its body forward.
This causes the abdomen area to contract and gives the worm the
appearance of arching its back. |

Emerald Ash Borer | The emerald ash borer (Agrilus planipennis Fairmaire) is a
wood-boring beetle native to eastern Asia and is now considered
the most destructive forest pest ever seen in
North America. Since its discovery in Michigan in 2002, it
has killed tens of millions of native ash (Fraxinus spp.) trees in
the United States and Canada. This destruction has already cost
municipalities, property owners, and businesses tens of millions
of dollars in damages. |
