Most homeowners have never stopped to think about what a bark inclusion on a tree is. This term doesn’t come up often unless you’re talking to an arborist. But bark inclusion on trees is a serious, hazardous structural condition worth understanding. As a trusted provider of tree services in Lakeland, TN, Spruce Up Tree Care covers what you need to know about this common structural defect.
Why Bark Inclusion on Trees Develops
A bark inclusion forms when bark becomes trapped between two stems or between a branch and the trunk. Instead of developing solid wood at that connection, the tree traps bark inside the union. That weak connection cannot support weight as effectively. The problem usually develops as the tree continues growing.
Several growth patterns create this structural weakness. Narrow V-shaped branch angles leave little room for normal growth. Co-dominant stems also compete for space and press together over time. Fast-growing species, such as silver maples, red maples, pears, crab apples, and willows, often develop weak unions more quickly due to their rapid growth.
Some species also lean more naturally toward this growth pattern.
Signs of Bark Inclusion in Trees
You can spot warning signs before a branch fails. Look for these features during routine tree inspections:
- A narrow V-shaped branch union
- A visible seam running through the junction
- Bark folding inward between stems
- Two stems pressing tightly against each other
If you have wondered what a bark inclusion on a tree looks like, these visible features provide some of the clearest clues.
How Bark Inclusion Affects Tree Health
A weak branch union relies on bark instead of strong wood. That reduces the tree’s structural strength as it grows larger. Extra weight places increasing pressure on the weak connection.
Strong winds, heavy snow, or ice can force the union apart. Deep cracks may extend into the trunk after the split. Branch failure also increases the risk of damage to nearby people or property.
The trapped bark prevents a strong wood connection from forming. If the union cracks or splits, the resulting wound can make the tree more vulnerable to decay, disease, and insect activity.
Treating Bark Inclusion in Trees
The right solution depends on the tree’s age and the severity of the weak union. Young trees usually benefit from structural pruning before the problem becomes serious. Removing or reducing one competing stem encourages stronger future growth.
Mature trees may need cabling and bracing for extra support. These systems help reduce movement during storms while lowering the chance of splitting. Some trees require selective stem removal as pressure increases.
In severe cases, removal provides the safest option, especially near homes or walkways. Regular inspections also help identify developing problems before they become dangerous.
