The Importance and Procedures for Employing a Tree Expert

A tree whisperer, in essence, is someone who's learned the ropes of arboriculture, the art, and science behind selecting, planting, and maintaining trees. These individuals are well-versed in the needs of trees, preparing them to be the guardians of nature's green giants.

Don't underestimate the importance of an arborist. This friendly neighborhood tree warden can add to your property's value and make it stand out from the crowd. A study in Cincinnati's neighborhoods revealed that trees accounted for 10.7% of a home's sale price, on average [Dimke et al., 2013].

Urban trees offer remarkable benefits to our communities. They work tirelessly to filter out airborne particles, produce oxygen, absorb carbon dioxide, and intercept stormwater runoff. Lush green canopies can help lower air conditioning demands and save energy during the scorching summer season. Simultaneously, their windbreak can lessen the chill in the winter [Wolf et al., 2020].

Good times or bad, urban trees have a positive impact on human health [Jonnes, 2011; Nowak et al., 2014], with their demise often resulting in detrimental effects on local populations.

A poorly maintained tree can become a significant hazard, reducing property values and even posing risks to human life, as seen in Figure 2. Prevent such calamities by keeping pest and disease problems under control. Only a qualified tree-care professional should be entrusted to handle such tasks, as mismanagement can shorten a tree's lifespan.

Hiring an arborist isn't a task to be taken lightly. The International Society of Arboriculture (ISA), a non-profit organization, offers proof of expertise through various credentials. To find an ISA-approved arborist, simply search the ISA website using your zip code or city.

The ISA offers a hierarchy of certifications, with the ISA Certified Arborist being the foundation. Arborists with this certification carry expertise in tree biology, soil management, tree installation, pruning, tree diagnostics, protecting trees from construction damage, and ensuring tree worker safety [Figure 3].

The ISA also offers certifications for Tree Climbers and Aerial Lift Specialists, who specialize in climbing trees and working at heights with equipment like a bucket lift, respectively. ISA Climber Specialists are skilled at diagnosing tree conditions, particularly stem decay, while Aerial Lift Specialists tackle similar duties from the safety of a bucket lift [Figure 6 and 7].

If you need branch removal on a large mature tree and the work requires climbing, ensure that an ISA Climber Specialist is assigned to the job. Similarly, only hire an ISA Aerial Lift Specialist if work is to be performed using a bucket lift.

An ISA Utility Specialist performs tree work around high voltage lines, while ISA Municipal Specialists focus on managing urban trees in local communities [Figure 6]. Advocate for your municipality hiring a municipal specialist if they're assessing trees or carrying out work, such as selective pruning or tree removal.

When it comes to assessing tree risks, trust only an arborist holding the ISA Tree Risk Assessment Qualification (TRAQ). This certification ensures the professional has the necessary expertise to systematically evaluate trees based on internationally recognized criteria [Figure 8 and 9].

To hire the right arborist, follow these useful tips:

1. Verify the responsible party for the tree. Consult with your municipality's public works or urban forestry department if needed.
2. Decide on the type of tree service you need, which helps you choose the suitable arborist.
3. Visit the ISA website (isa-arbor.com) to find arborists in your area based on their credentials. You can also search online and opt for accreditation with the ISA or ASCA.
4. Ask for the qualifications of their arborists, seek quotes and ask for references before making a decision.

Avoid common pitfalls, such as door-knocking salespeople after storms or invasive tree species outbreaks. Be wary of rushed bargains or time-sensitive deals and never pay in advance.

Additional tips include double-checking permits and licenses for contractors. When a pesticide application is required, confirm that the company has a current pesticide applicator license through the Ohio Department of Agriculture. Finally, request certificates of insurance for liability coverage and worker's compensation.

Opt for an arborist who refrains from using climbing spikes if the tree is to remain in the landscape and one who never advocates for "tree topping," or removing a tree's top portions [Figure 11 and 12]. While utility companies may need to top trees for utility line clearance, they are not to blame when such measures are required [Figure 14].

Remember that reputable arborists have substantial investments in equipment and training. Their trucks, tools, labor, safety training, and continuing education contribute to the cost of their services. Inspect contracts carefully, and don't be afraid to ask questions before signing on the dotted line.

Finally, a healthy, well-maintained tree can be a thing of beauty. Don't let a poorly maintained tree threaten your property or the lives of those around it. Seek the help of a trained and certified arborist today.
