Mangrove Trimming

Mangroves are valuable aquatic plants that grow in environmentally sensitive areas and are regulated by state and local government. Boen’s employs a Professional Mangrove Trimmer registered with the Florida Department of Environmental Protection. We can prune mangroves to the extent allowed by law while taking care not to damage aquatic grasses, prop roots or pneumatophores growing in the mangrove area. In addition, we can identify and remove undesirable vegetation growing in the mangrove areas. If you have decided to have your mangroves trimmed we can assist with obtaining a permit to trim mangroves or determine if you qualify for an exemption.

Tree Preservation During Construction

Boen’s specializes in saving trees impacted by construction activities. Our ISA Certified Arborist has over 20 years of experience in tree preservation related to all types of construction activities. Real tree preservation means that the tree(s) will remain in a healthy growing condition long after construction is complete. We offer the following services relating to new construction:

  • Tree assessments to determine what trees are best to be preserved.
  • Development of a Tree Preservation Plan
  • Assistance to the development team with site analysis to incorporate valuable existing trees into the site design
  • Work closely with general contractor and sub-contractors to resolve tree/construction conflicts.
  • Construction of aeration systems and tree wells
  • Installation of tree barricades
  • Root Pruning
  • Tree pruning and removal
  • Innovative parking lot construction to accommodate existing root systems
  • Soil aeration
  • Work with regulatory officials on compliance issues
  • Represent client at public hearings to explain the Tree Preservation Program
  • On-site compliance inspections during construction
  • Tree transplanting
  • Development of a post-construction tree care program

Storm Damage Prevention / Crown Restoration

The Tampa Bay area is subject to severe weather on an annual basis. Thunderstorms accompanied by heavy rains, high winds and lightning are commonplace in the summer months and tropical storms, hurricanes and tornadoes threaten our area as well. In 2004, Hurricanes Frances and Jeanne caused widespread damage to trees in Tampa Bay. Thousands of trees suffered severe damage in the form of uprooting, shearing, and splitting. The majority of these trees were predisposed to failure because of structural defects, internal decay, improper pruning, species characteristics or the placement of the tree in the landscape. Most of the storm-related damage could have been avoided through a proactive program of preventative tree maintenance. Boen’s offers the following services that can repair storm-damaged trees and prevent damage from occurring in the future:

Hazard Inspection

An ISA Certified Arborist from Boen’s can inspect your tree(s) for problems that could lead to storm failure and recommend solutions. The area surrounding the large structural roots, root flare, trunk, large scaffold branches, upper crown, and overall structure will be inspected and assessed and a written report of the findings will be submitted to you and discussed. The report will include specific recommendations designed to prevent storm-related damage. The best time to have your trees inspected and have preventative maintenance performed is January through April before the onset of our summer storms; although a hazard inspection can be conducted at any time. Phone Boen’s to set up a hazard inspection.

Crown Repair for Trees

Hurricanes Frances and Jeanne caused some measure of damage to all trees in the Tampa Bay area. While some trees experienced major structural failure, many trees simply suffered from broken, split or sheared branches in the upper crown. Broken, split or sheared branches are open wounds that are entry ports for decay-causing organisms and they should be repaired. The tree has a difficult time compartmentalizing (healing) wounds of this type and once decay is established in the smaller branches it may progress internally down into the larger structural branches. Ignoring open wounds on a tree can lead to major structural failure years later. The Arborists at Boen’s is trained to recognize and repair this type of damage. Have your trees repaired as soon as possible after storm damage. By acting promptly you can avoid future property damage or personal injury incidents relating to structural failure.

Crown Reduction (drop crotch pruning) on Trees

During the storms, many trees incurred serious damage to the large scaffold (leaders) branches that are the framework for the tree’s crown. An alternative to removing these trees is to perform crown reduction pruning. Crown reduction is a procedure used to reduce the height of a tree by utilizing proper pruning cuts. It is not topping which is reducing the height of a tree by utilizing indiscriminate heading cuts. Topping causes internal decay and leads to a hazardous tree. Crown reduction is accomplished by pruning a leader back to a lateral branch at least one third the size of the diameter of the leader and capable of becoming the new leader. The result is a shorter but stronger tree through the improved structure. Crown reduction is an acceptable method to reduce the height of damaged trees or trees that are prone to breakage. Many tree species such as the native sweetgum (Liquidambar styraciflua) and tropical hardwoods such as the ear tree (Enterolobium cyclocarpa) are prone to experience breakage of the upper crown. Crown reduction can also be used for trees that are located underwires or other overhead obstructions. An Arborist from Boen’s can determine if crown reduction pruning is advisable for your tree.

Subordinate Tree Pruning

One of the most dramatic tree failures observed during this past storm season was caused by the structural defect of codominant stems. Codominant stems are structurally weak and occur when two or more stems of essentially the same diameter emanate from the same union. If the bark is included the attachment becomes very weak. This is a defect common on urban trees with spreading crowns but rare on forest trees. Codominant stems are particularly dangerous when it involves multiple trunks that are attached at the base of the tree or when they involve the large scaffold branches low in the crown. Failure of low codominant stems can cause the entire tree to fall. A trained arborist can identify included bark in the crotch of codominant stems. Once detected the arborist can prescribe treatment depending on the size of the tree. If the tree is not too large the structure can be improved through subordinate pruning. Subordinate pruning is a specialized procedure designed to remove codominant stems and establish a central leader. The result is a tree with a strong structure that will be more capable of withstanding high winds. If a tree is large the codominant stems will not be able to be removed but will have to be cabled and braced with hardware. Codominant stems are major structural defects of urban trees and should be treated before they fail. A hazard inspection by Boen’s Certified Arborist will identify this defect and prescribe a treatment.
