Trees, like all living organisms, need to be protected from pests and diseases. They also need healthy and free-flowing soil that has plenty of air and water.
There are many different types of pests and diseases that affect trees, some of which are natural and others that are non-native. These pests and diseases can significantly alter the cycle of regeneration, affecting both young and old trees.
In addition, clog gutters nearby a tree could also cause the pest to get into your tree and make it looks so dry. This is because, if your gutters are clogged with debris such as leaves, twigs, and branches, they can become a breeding ground for insects like mosquitoes and flies. These insects can then spread diseases to your trees. If this is already the situation of your gutter, better to hire a professional gutter cleaning service like Gutter Cleaning York PA to help you solve the problem easier.
Some of the most common and devastating forest insects and diseases include chestnut blight, Dutch elm disease, oak bark disease, spongy moth defoliation, hemlock woolly adelgid, and emerald ash borer. DCNR’s Bureau of Forestry monitors and manages these pests to ensure that our forests stay healthy.
The first line of defense a tree employs to defend against fungi and disease is its vascular system, which circulates water, sugars, and other nutrients throughout the wood. When a wound occurs, the tree converts its stored sugars into a variety of defensive chemicals and deposits them around the wound in a specific pattern called CODIT compartmentalization.
This pattern of chemical walls helps prevent insects and diseases from spreading into the surrounding tree. During this process, the tree also creates a number of physical boundaries that protect the unwounded part of the tree from decay.
Another way that trees guard against damage is by using their immune systems. They produce special fungicides that help protect against diseases that attack the roots of the tree. In addition, trees have protective structures, called branch collars, located at the base of each branch that help them form a natural defense system.
These special structures are critical to protecting the health of a tree and ensuring that its branches will grow strong and develop well. To maximize these protective capabilities, trees should be kept well-watered during dry spells and mulched at the dripline (the point where water enters the trunk) to minimize root stress.
Aside from the protection that trees provide against pest and disease, they offer a place of refuge and beauty to those who appreciate them. In addition, trees are important sources of food and shelter for animals and birds.
Trees can be damaged and killed by a wide range of factors, including construction activity such as grading, trenching, and paving; building sidewalks, driveways, pools, patios, and home additions; landscaping lawns and lots; pruning trees incorrectly; and soil compaction.
During construction, trees are often damaged by soil compaction, grade changes, root crushing and pruning, and damage to the bark. Trees can also be injured by improperly stored or dumped construction materials.
The most effective method of preventing a tree from being damaged during construction is to plan for compatible landscapes and amenities that allow trees to thrive. This can be done by developers and homeowners.
Despite the best efforts of tree advocates, some preserved or planted trees will be injured by construction activities. Some of these injuries may be minor or not serious enough to kill the tree.
