Oak trees are a valuable part of the natural landscape in Anne Arundel County. They provide
many benefits beyond their beauty such as oxygen production, improved water quality, carbon
sequestration, and habitats for wildlife. However, oak trees, both red and white, are facing a
significant threat in the form of oak decline, a condition that affects the health and vigor of the
tree. A recent study completed by Anne Arundel County Forestry Department estimates that
23.4 acres of tree canopy was lost within 3 years to oak decline, and the losses will continue
into the foreseeable future.
What is oak decline?
Oak decline is complicated without one specific cause. According to the Anne Arundel County
Forestry Division, oak decline can be caused by a combination of factors such as environmental
stress, pests, and diseases. Signs of oak decline include thinning foliage and dieback of
branches, which can eventually lead to the death of the tree.
Several factors can contribute to oak decline in Anne Arundel County. For example, drought,
temperature fluctuations, and poor soil quality can all weaken the tree’s defenses and make it
more vulnerable to pests and diseases. Common pests that can cause significant damage to
oak trees include gypsy moths, oak sawflies, and oak borers. Diseases such as oak wilt,
bacterial leaf scorch, and anthracnose can also weaken and damage the tree.
What can be done to prevent oak decline?
As a homeowner, it’s essential to be aware of the signs of oak decline and take steps to prevent
it from affecting your oak trees. Regularly monitoring your trees for signs of decline, such as
thinning foliage or dieback of branches, can help detect the condition early. Contacting a
professional arborist or the Anne Arundel County Department of Natural Resources Forestry
Division to assess the health of your trees and recommend appropriate treatment options can
also help prevent further decline.
In addition, implementing proper tree care practices such as watering, mulching, and regular
pruning can help improve the health of your oak trees and reduce the risk of decline.
How is oak decline treated?
If a tree on your property is showing signs of oak decline, it’s crucial to take action to prevent the
condition from worsening. A professional arborist or the Anne Arundel County Forestry Division
can assess the health of your oak tree and determine the underlying cause of decline. They can
recommend appropriate treatment options, such as pruning or fertilization, to improve the tree’s
health, and hopefully extend its life for a few more years. In some cases, it may be necessary to
remove the tree to prevent the spread of disease or to eliminate safety hazards.
Proper tree care practices, such as watering, mulching, and regular pruning, can help improve
the health of oak trees and reduce the risk of decline. The Anne Arundel County Forestry
Division offers resources and guidance on proper tree care practices that can be implemented
to support the tree’s health.
In some cases, if the oak tree is significantly declining or poses a safety hazard, removal may
be the best solution. Removing the tree can prevent the spread of disease to other trees in the
area and eliminate the risk of the tree falling and causing damage or injury. Many trees that are
initially treated for oak decline will need to be removed in their entirety within the upcoming
years.
If the oak tree must be removed, homeowners can consider planting a replacement tree in its
place. The Anne Arundel County Forestry Division can recommend appropriate tree species
based on the site conditions and the homeowner’s goals.
In summary, as a homeowner in Anne Arundel County, it’s important to be aware of the signs of
oak decline and take steps to prevent it from affecting your oak trees. By monitoring your trees
for signs of decline, contacting a professional arborist or the Anne Arundel County Department
of Natural Resources Forestry Division, and implementing proper tree care practices, you can
help protect the health and longevity of your oak trees. If a tree on your property is subject to
oak decline, a professional arborist or the Anne Arundel County Department of Natural
Resources Forestry Division can assess the tree’s health and recommend appropriate treatment
options or removal.
