- Symptoms: These tree trunk infections called burls look like bumps or warty growths probably caused as a result of environmental injury. Cambial growth is hyper-stimulated as a way for the tree to isolate and contain the injury. Almost all burl wood is covered by bark, even when underground.

Welcome Ash Dieback is caused by a fungal infection, now known as Hymenoscyphus fraxineus (aka H. pseudoalbidus, or Chalara fraxinea). Ash dieback has moved rapidly across Europe since the early 1990's, decimating ash tree populations.sh dieback symptoms include bark lesions (above) and crown dieback, leading to tree death. 80-99% of our ash trees may die from the disease within the next 20 years or so.

- POSSIBLE CAUSES. Cracking of exterior wood or plywood as it expands and contracts in response to changes in temperature and humidity, which is transmitted through the paint. Poor paint penetration, especially on wood with an excessive amount of hard-/flat-grain pattern, which is smooth, hard and nonporous. Poor surface preparation.

Wood Decay Wood Decay. Wood decay, also known as wood rot, is the decomposition of wood as the result of actions by certain species of fungi. According to Ohio State University, replacement materials needed to repair damage caused by decay account for nearly 10% of U.S. annual wood production.

Apple Trees With Black Bark Damage. As the name suggests, fire blight often gives trees a scorched appearance, as though they were burned with fire. Black bark, black shriveled twigs, shoots, leaves and fruit are signs of a fire blight infection. In addition, flowers become brown and shriveled, while brown cankers develop on limbs.

Remedies: Borer, rot and mould Remedies: Borer, rot and mould Borer damage is frequently found in old villas, especially where sapwood rimu and untreated air dried pine have become damp. Rot and mould are also common when moisture is present.

- One of the most common reasons for hardwood floors to bow is water damage. If the water pipes are leaking, or water has spilled then this can cause the wood to expand and bow to accommodate the extra mass. You need to check for water leaks and mop up the extra water before fixing the leak.

Mold and mildew usually not a threat to lumber -- unless you cover it before it's dry Some lumber provides plenty of food for the mold and mildew to grow rapidly. When you see the black mold cover wide areas of lumber, usually this happens because the wood got wet and stayed wet while it was being stored. If it's warm and humid, the growth of the mold and mildew can be rapid.

Recognizing and Controlling a Tree Burl Apparently, little research has been done to confirm the cause or causes of burls. Available sources suggest that a burl could be caused by many environmental factors, but the biology of burls on trees is not well known.

Bark Splitting on Trees Bark splits are not likely to be fatal to trees, although they will, in some cases, allow entry of disease organisms which can cause decay. Through proper treatment to encourage the natural callusing process, a tree should be able to close most splits. There is no single reason for bark splitting on trees. During late winter and early spring, severe cold followed by rapid thawing can result in splits referred to as “frost cracks”. These frost cracks can actually start from a wound inflicted earlier in the tree’s development.

- Tannic Acid is contained the lumber. When it comes in contact with any metal, a black stain will form. In addition , over time, Redwood will trun a grayish color because of Tannic Acid. There are many products on the market that will take off the stain.

- 2.0 Causes of biodegradation: 2.1 Decay: Wood decay is deterioration of wood by primarily enzymatic activities of micro organisms. These micro organisms are primarily the fungi. A wood decay fungus is a variety of fungus which has the ability to digest wood causing it to rot.

Types of Fungi: Mushrooms, Toadstools, Molds The types of fungi that cause wood decay are important in recycling nutrients from fallen trees but are a menace in homes and other buildings. Wood decay fungi are usually broken into three groups: Brown rot fungi that produce hydrogen peroxide which attacks cellulose. Soft rot fungi that produce an enzyme called cellulase which digests cellulose

Installation If the cause of the splitting in your wood floor is high humidity, a dehumidifier is often enough to prevent further splits until you can remove the source of the moisture. Inspect your ductwork, as well, to eliminate the possibility of excessive drying, particularly if the splitting is limited to one area of the floor.ood is a porous material, and while wood flooring is sealed with a protective coating, the surface beneath it is not. As a result, the wood naturally expands and contracts with humidity and other moisture.

Decay development Wall 4 prevents discoloration and decay organisms from moving into the wood produced after the injury occurred. This means it is extremely difficult for discoloration or decay to move from inside wall 4 to the outside of wall 4. Although this task appears simple, it is vital to the longevity of trees.

Pile and Windrow Burning Forest managers can take many steps to minimize these debris problems. Much of the larger material left after harvest is cull hardwood, and periodic use of underburns during the rotation will reduce the number of large hardwoods at harvest. Some of the cull material can often be sold or given away as firewood.

Oak wilt in Minnesota Oak wilt, caused by the non-native fungus Ceratocystis fagacearum, is responsible for killing large numbers of oaks annually in Minnesota. Oaks are a valuable and abundant shade and forest tree in the state. Oak wilt is most severe in red oak group species such as northern red oak and northern pin oak (Fig. 1). Fortunately, this valuable resource can be protected by utilizing effective management techniques.

- Because of its fire and drought resistance, bur oak is the most common tree on oak savannahs along the prairie-forest transition zone in Wisconsin and Minnesota. Bur oak wood is commercially valuable for sawlogs and veneer, although high quality timber is not common. Their acorns are a prime food for squirrels, wood ducks, white-tailed deer, and small mammals. Bur oak is one of the most drought resistant North American oaks. On uplands it often is associated with soils of limestone or sandstone origin. It is found on droughty sandy plains, black prairie loams, and on loamy slopes of south and west exposure.

WOODEN TONGUE Wooden tongue is an infection caused the rod-shaped bacterium, Actinobacillus lignieresii, which lives only in the presence of oxygen.The bacteria, which live in the mouth, invade tissue through breaks in the lining of the mouth.Any rough feed can cause mouth abrasions which allow entry of infection. Wooden tongue occurs almost entirely in soft tissue with the tongue and lymph nodes of the head most often affected.The disease starts suddenly with the tongue becoming hard, swollen and painful.Affected animals drool saliva and may appear to be chewing gently.ooden tongue is an infection caused the rod-shaped bacterium, Actinobacillus lignieresii, which lives only in the presence of oxygen.

Other Ash Problems Ash Borer is a native clear wing moth that can kill smaller trees. This moth leaves round pencil sized holes in the trunk. Unlike EAB, this insect removes frass from its larval galleries. The frass tends to pile up around the base of the tree and looks like a small pile of sawdust.ree symptoms look very similar to Emerald Ash Borer but there will be no S-shaped galleries under the bark and no D-shaped exit holes on the trunk. Ash Yellows is another disease that causes trees to decline and die over time.

- Armillariaand the disease it causes have several common names. Shoestring root rot refers to the rootlike fungal structures, called rhizomorphs, that spread the fungi. The names honey mushroom, honey agaric, mushroom root rot, or toadstool disease refer to the mushrooms produced. Conifers often respond to infection by producing a copious flow of resin, hence, the names resin glut or resin flow. When oaks are the common host, Armillaria is often called the oak fungus.

Dry Rot â The Facts from the Dry Rot Experts Thus, for the decay to become initiated the wood must usually be physically wet. This usually occurs as the result of severe water ingress in the form of rainwater leaks, plumbing defects, floods, long term severe condensation, etc. Further pre-requisites for initiation of decay are still and humid conditions.
