Decay-softened wood provides favorable habitat for other decomposer organisms that form the basis of the food chain in forest.
Traveling across the state, you soon discover that Oregon is home to a wide range of trees. There are 30 native coniferous species and 37 native species of broadleaf trees. Oregon varies greatly in terms of elevation, temperature, wind, rainfall and soil composition.
Combinations of all these factors help determine the dominant tree species of an area. Many of the most important tree diseases, such as stem decays and root diseases, involve wood decay. Decay of wood in trees on developed sites and urban landscapes is an important cause of tree hazard by creating tree defects that increase the likelihood of mechanical failure.
Short-term responses to stem wounding were measured over a day period on six tree species found in seasonally dry tropical forest in Bolivia.
Three types of wounds were inflicted to simulate mechanical bark damage and bark damage caused by low- and high-intensity fires. Managing Tree Wounding and Stem Decay in Oregon Forests How to identify, manage, and prevent forest tree stem (trunk) decay.
Also discusses ecologic roles of decay and decay fungi and economic losses from tree wounding and decay. Management guidance in this book complements Field Guide to the Common Diseases and Insect Pests of Oregon and Washington Conifers (Goheen, E.M., and te,USDA Forest Service), which is an identification guide.
Wetwood is wood in a living tree that appears watersoaked, darker than normal wood, has a fetid odor, and is colonized by bacteria. It is common, even the normal condition, in the inner wood of many tree species. It benefits the tree by inhibiting wood decay, but in some cases, it.

National Forests in eastern Oregon and Washington were sampled to determine the incidence of fungal infection and stem decay (Filip and others ). A variety of stand and tree characteristics were recorded to relate these to amounts of stem decay.

The bark is grayish with shallow ridges and fissures, leaves are dark green with deep lobes on each side and acorns are about one inch long, with shallow, scaly cups. A total of Douglas-fir trees were treated to determine whether fungal inoculation with rifle or shotgun promoted stem decay and subsequent use by cavity-nesting birds in the Coast Range in Oregon.
The two basic types of tree wounding are stubs and scars. Stubs. A stub is created when tree branches or tops break off or die. They can stick out from the stem and prevent the wound from closing and healing or leave a giant hole, both of which invite decay. Storms with intense winds commonly knock tree branches off and cause stubbing.
Scars. Selective harvest activities and weather events that cause limb breakage and bole wounding can initiate decay formation by activating resting spores inside the tree bole. Decay caused by E. tinctorium is often most common in the mid-bole, but may also extend into the butt or upper region of the stem.
On average, trees with a single conk contain. stem wounding. Arboricultural Journal – for black bear tree selection. Forest Ecology Management. – improper flush-cut pruning may result in greater tree decay that.
It is part of a good hazard tree management program. An organization at some level must provide the service of receiving reports, incorporating them into a database, and analyzing the data. Untilthe best known and most successful reporting system was the California Tree Failure Report Program.
USDA Forest Service. The Douglas-fir tussock moth (Orgyia pseudotsugata) is an important defoliator of true firs and Douglas-fir in Western North America. Severe tussock moth outbreaks have occurred in British Columbia, Idaho, Washington, Oregon, Nevada, California, Arizona, and New Mexico, but the moth causes notable damage in a much.

Damage to the roots and root collar region, and the main stem, is much more significant than damage elsewhere on a tree.
In aspens, main stem decay from hypoxylon canker and white trunk rot are very damaging, resulting in tree mortality and wood volume loss, respectively. Forest Service, Vol.

Planted too deeply, it will be stressed from the start, may produce girdling roots or succumb to stem decay. Plant it where it is too exposed or the soil PH is wrong and it may survive, but not have the vigour or vitality of a well-sited tree.
Grown in the open, it encounters a greater array of forces than a forest tree. Stem decay losses in white fir can be large, with over 20% attributable to annosus root disease in eastern Oregon [10,11].
Annosus root disease may be the most damaging pathogen to true firs east of the Cascades in the Pacific Northwest. Although it does not usually kill white fir directly, annosus produces moisture stress and loss of vigor. ing to 45% of tree height had no effect on growth which was reduced with greater crown removal.
Suggests maintaining a live crown ratio of 55%. Tasmania Australia. Schwarze, F., J. Gruner, M. Schubert, and S. Fink. Defence reactions and fungal colonization in Fraxinus excelsior and Tilia platyphyllos after stem wounding. Root infections may lead to root and lower bole decay; the tree dies directly or as a result of windthrow.
Trunk infections lead to stem decay. Bark beetles also often infest infected trees. The disease can be found in forests, ornamental plantings, and Christmas tree plantations where true fir.
Infections often occur through branch stubs or wounding such as pruning. Nectria cankers are targetlike in appearance because the canker grows at the same rate as the callused growth (Figure ). Affected forest trees are of low merchantable value. Yard trees should not be pruned during wet weather since infection is highest at this time.

Few are economically important. Trunk rot is caused by Phellinus igniarius, which is reported to have some economic impact in timber, pulp, and recreation sites in British Columbia.
Rough bark is caused by Didymosphaeria oregonensis and is thought to be limited to young trees. Fomitopsis pinicola, is a stem decay fungus common on softwood and hardwood trees. Its conk (fruit body) is known as the red-belted species is common throughout the temperate Northern is a decay fungus that serves as a small-scale disturbance agent in coastal rainforest ecosystems.
It influences stand structure and succession in temperate rainforests. Stem Decays • Tree Wounding a major factor. – Planned directional felling, skid road placement – Bumper trees, removed last • True Heartrots – In true firs there is someIn true firs, there is some evidence that Echinodontium tinctorium (Paint fungus) lays dormant inside the tree and when the tree is stressed or wounded, it is.
Tree decay fungi - Identification and Significance. The Kingdom of fungi is vast, fungi play vital roles in many ecosystems and are crucial to the lifecycles of many plant species on this planet.
Connections between fungi and trees are often critical in determining tree vitality and stability. OTHER WOUNDING AGENTS. Use of Mowers and Other Yard Equipment.
Trees are often wounded by careless use of yard equipment like mowers, weed whips, and other trimming equipment. These injuries cut through important vascular tissue just inside the bark which can lead to decay and ultimately death of the tree.
