Most homeowners call a tree service when something has already gone wrong. The tree is dead, the branch has fallen, the storm has split the trunk. An arborist is the person you call before things go wrong, and knowing when that call is worth making can save a tree, prevent property damage, and avoid the much higher cost of emergency removal.
This guide covers what an arborist does that a general tree service might not, the signs in your trees that warrant an arborist’s assessment, and how to find qualified help in Arkansas.
What an Arborist Is
An arborist is a specialist in the care of individual trees. The term covers a range of qualifications, from experienced tree workers with years of field knowledge to ISA-certified arborists who have passed a standardized exam covering tree biology, diagnosis, pruning, planting, and risk assessment.
The distinction between an arborist and a general tree service is one of scope. A tree service removes trees, trims branches, and grinds stumps. An arborist does those things, but also diagnoses tree health problems, recommends treatment plans, assesses risk, and provides guidance on whether a tree should be saved or removed.
Not every tree situation needs an arborist. A straightforward removal of a dead tree is a tree service job. A living tree that looks sick, leans in a new direction, or has structural features you are not sure about is an arborist job.
Signs Your Tree Needs Professional Assessment
Trees communicate their health through visible signs. Knowing which signs are normal and which signal problems helps homeowners decide when to call for help.
Mushrooms or fungal growth at the base. Fungi growing at the base of the tree or on the roots usually indicate internal decay. The tree may look healthy above ground while the trunk or root system is compromised below. A tree with significant basal decay can fail suddenly because the structural wood is gone.
Cracks in the trunk. Vertical cracks, especially deep ones or ones that extend through the trunk, indicate structural compromise. Frost cracks (common in Arkansas after rapid temperature swings) are usually superficial. Structural cracks that separate the wood are a different category and require assessment.
Dead branches in the upper canopy. A few dead branches in an otherwise healthy canopy may be normal. A pattern of die-back starting at the top and working down often signals root problems, vascular disease, or environmental stress. If more than 25 percent of the canopy is dead, the tree needs assessment.
Leaning that was not there before. A tree that has always leaned at a slight angle is probably fine. Its root system has adapted to the lean. A tree that has recently shifted, especially after heavy rain or soil disturbance, may have root plate failure in progress. This is urgent.
Bark falling off in large sections. Some species shed bark naturally (sycamore, birch). Bark falling off in patches on species that do not normally shed often indicates disease, insect damage, or sun scald.
Leaf problems. Leaves that are significantly smaller than normal, discolored uniformly (not just fall color), dropping much earlier than neighboring trees of the same species, or failing to leaf out in spring are all signs of stress. The cause could be root damage, soil compaction, chemical exposure, disease, or insects.
Insect activity. Small holes in bark (borers), sawdust-like frass at the base (borers or carpenter ants), webs (webworms, tent caterpillars), or visible insect populations on leaves or bark may or may not be serious. An arborist can identify the insect and determine whether treatment is necessary.
Root disturbance. Construction, trenching, soil grading, or paving near a tree can damage roots that are not visible. Trees can take 2 to 5 years to show symptoms from root damage, so a tree that was fine when the driveway was poured may start declining years later.
Co-dominant stems with included bark. Two main trunks growing from the same point with bark pinched between them create a structural weakness. This is one of the most common causes of whole-tree failure in mature trees. An arborist can assess the risk and recommend cabling, bracing, or selective removal of one stem.
What an Arborist Assessment Looks Like
A typical tree assessment involves a visual inspection from the ground, sometimes supplemented with tools. The arborist examines the trunk for cracks, decay, and structural features. The root flare is checked for girdling roots, decay indicators, and soil conditions. The canopy is assessed for dead wood, crossing branches, dieback patterns, and overall vigor. The lean is measured if applicable.
For trees with suspected internal decay, specialized tools can assess the extent. A resistograph (a drilling device that measures wood density) or a sonic tomograph (which maps internal wood quality using sound waves) can reveal decay that is not visible from the outside.
The assessment results in a recommendation: the tree is healthy and needs routine maintenance, the tree has a treatable condition and here is the treatment plan, or the tree is a removal candidate and here is why.
When to Save vs When to Remove
This is the question arborists answer most often. The answer depends on the tree’s health trajectory, its location, and the risk it poses.
Save when: The problem is treatable (insect infestation, nutrient deficiency, minor disease). The tree has significant remaining life expectancy. The tree is structurally sound and the issue is cosmetic or early-stage. The tree is large and mature and contributes significantly to property value.
Remove when: More than 50 percent of the canopy is dead. The trunk has significant structural cracks or extensive internal decay. The root system is compromised (leaning, root plate lifting, major root damage from construction). The tree is dead. The tree poses an imminent risk to people or structures that cannot be mitigated by pruning or cabling.
In the gray area between save and remove, the arborist’s experience and judgment matter. A tree that one company recommends removing may be saveable with the right treatment plan from a more experienced assessor. This is why getting a second opinion on a removal recommendation for a large, valuable tree is often worth the cost of a second assessment.
Tree Health in the Ouachita Region
The Hot Springs area has specific tree health challenges tied to its geography, climate, and soil.
Oak wilt is present in Arkansas and can kill red oaks rapidly. Symptoms include wilting leaves starting at the branch tips and progressing inward, premature leaf drop, and fungal mats under the bark. If suspected, call an arborist before pruning, because pruning during oak wilt season (April through July) can spread the disease through exposed wounds.
Pine beetle infestations affect the native pine population. Signs include pitch tubes on the bark, boring dust, and needles turning brown from the top down. Once a pine is heavily infested, removal is usually the only option, but surrounding pines can sometimes be protected with preventive treatment.
Soil conditions in the Ouachita region include rocky, shallow soils on hillsides and clay-heavy soils in valleys. Both affect root development and tree stability differently. Trees on shallow rocky soil may have limited root anchorage despite appearing healthy. Trees in clay soil may struggle with drainage during wet seasons.
Finding an Arborist in Arkansas
The International Society of Arboriculture (ISA) maintains a searchable directory of certified arborists. Searching by zip code returns ISA-certified professionals in the area. Certification is not a legal requirement for tree work in Arkansas, but it indicates the arborist has demonstrated competency in tree care fundamentals.
Beyond certification, look for the same credentials that matter for any tree service: insurance (general liability and workers’ comp), experience in the area, references, and a willingness to explain the assessment and the recommendation.
