Diagnosing tree diseases can be difficult. Obviously, trees cannot tell you how they are feeling or that something seems wrong. Nevertheless, they do show signs of illness on their bark, branches, leaves, and trunks. The trick is to recognize these abnormalities and determine what they mean. The following signs of disease may indicate that you need tree service Old Lyme CT.

1. Canker

A canker occurs due to damage or stress from weather conditions, trauma, or fungal infestation. It is a localized dead area that may grow in size to form a lesion. The bark in this area may become discolored. Cankers are especially dangerous to young trees, which may die as a result.

2. Changes to Leaves or Needles

Insect infestation or fungal infection can cause the leaves or needles of the tree to change colors. This may occur in localized areas, forming spots or scabs, or over the entire structure, causing a more uniform change of color that is abnormal. Another thing to watch for are small bumps on the leaves known as insect galls, which form when parasitic larvae inject chemicals into the plants.

3. Dieback

Dieback occurs when the branches at the top of the tree, i.e., the crown, lose their leaves. As the tree disease progresses, the dieback can spread to other areas of the tree. Without leaves, the tree eventually dies because it cannot perform photosynthesis to nourish itself. Emerald ash borer infestation often causes dieback in affected trees.

4. Loss of Leaves or Needles

Of course, it is normal for deciduous trees to lose their leaves in the fall, and coniferous trees shed needles continuously. However, when the loss of leaves occurs out of season, or when the leaves or needles do not grow back, it can be a sign of disease.

A diseased tree can be dangerous. Dead trees or branches are less stable and may fall, potentially causing injuries or property damage.…

Community safety measures such as fire hydrant flow test and fire danger ratings are meant to prepare for disasters and help to prevent them in the first place. The Forest Service uses a color-coded, five-level system to identify the risk and communicate it effectively to the public.

Extreme Fire Danger

Red signs indicate extreme fire danger. This means that all fires have the potential to get seriously out of control. They may be completely unmanageable in areas such as conifer stands and heavy slash. Flames can burn intensely and spread furiously under these conditions.

Very High Fire Danger

The Forest Service communicates very high fire danger by using orange signs. Fires increase quickly and spread rapidly under these conditions and are easier to start no matter the cause. One of the constant hazards associated with very high fire danger is spot fires, which ignite from flying embers or sparks outside the perimeter of the main conflagration.

High Fire Danger

Spot fires remain a hazard of high fire danger, but are more likely to occur only over short distances. It is necessary to fight a small flame immediately when the fire danger is high because it can get out of control very quickly. Yellow signs indicate high fire danger.

Moderate Fire Danger

When the fire danger is moderate, accidental fires are slower to start. They are also slower to spread in wooded areas, although they may spread more quickly in grassland. It is easier to bring a fire under control when fire danger is moderate, indicated with blue signs.

Low Fire Danger

When the fire danger is in the green, spot fires are unlikely. Fuels do not readily ignite unless exposed to an intense source of heat. Flames smolder slowly in wooded areas. They may burn freely in open grassland, but only for a few hours.…
