- Gypsy Moth Damage
-
The gypsy moth is the most important defoliating insect of hardwood trees in the Eastern United States. Since the turn of the century, millions of dollars have been spent in efforts to control or eliminate gypsy moth populations and to retard natural and artificial spread. In the early decades of this century, outbreaks occurred only in New England; today defoliation by the gypsy moth is far more severe and widespread.

- How to Save Dutch Elm Diseased Trees By Pruning
-
Dutch elm disease (DED), caused by the fungus, Ceratocystis ulmi, is the most devastating shade tree disease in the United States. Healthy elms can become diseased by 1) elm bark beetles that carry the fungus from elm to elm, or 2) through root grafting with already infected trees. Along with wilt symptoms, streaking (sapwood discoloration), a characteristic internal symptom of the disease, progresses rapidly down from limbs inoculated by bark beetles (Allison 1978).

- Pruning shade trees in the landscape
-
Pruning is a double-edged sword, either helping or hurting according to if, where, when, how, and why it is applied. When properly executed, a variety of benefits can occur. Benefits include reducing risk of branch and stem breakage, better clearance for vehicles and pedestrians, improved health and appearance, enhanced view, and increased flowering. When improperly performed, pruning can harm the tree's health, stability, and appearance and make matters worse.
- Pounce on Weevils to Protect Pine Seedlings

- Wood Surface Inactivation and Adhesive Bonding
-
From the instant an adhesive is applied to wood until the adhesive cures, several important steps must take place in order for a good glue bond to occur. If any of these steps do not occur, the glue bond will be faulty. Such is the case when gluing wood which is surface inactivated. The definition, causes, and prevention of surface inactivation in wood will be discussed below.

The decision to protect and preserve trees on a construction site is an important one. Many sites are chosen for residential or business use simply because the site contains a beautiful shade tree or offers a wooded environment. Often the very trees which are highly valued for their contribution to the aesthetic appeal of a site are inadequately protected or cared for during construction

Added: October 31, 2008The strength of tree stems is dependent upon stem thickness, stiffness, and ability to react to changes in aspects toward gravity and wind events. Materials added farther from the stem center (neutral axis) has a much greater impact on strength (per unit weight), than closer to the center materials. This positioning effect is the mechanic strength advantage seen when comparing hollow tubes and solid rods of equal weight, made of the same material -- the tube can resist force more effectively than the rod without deformation. The geometry of where materials are deposited change the strength for resisting bending and twist (torsion).
