Arbor Intelligence & Monitoring

AIM: tree care that keeps a record.

Most tree care is reactive: something looks wrong, a service is done, and the visit ends. AIM starts with a documented baseline and follows how your trees and their site change over time.

How it works

Evidence first. Then a decision.

We combine professional assessment with measurements, diagnostics, and records kept over time. That helps us decide what actually deserves intervention, and whether earlier work helped.

The goal is the root cause. Yellow leaves, pests, and disease are often downstream of one underlying problem, such as the soil, the water, or the site. Correcting that problem does the most to clear up everything that follows from it.

AIM doesn’t replace an arborist’s judgment. It gives that judgment more to work with.

Five questions, each building on the last

  1. What is happening?
  2. Why might it be happening?
  3. What evidence supports that?
  4. What should we do about it?
  5. Did the work actually help?

The AIM loop

Observe, measure, learn, adjust.

Each visit adds to the record, so the next decision rests on more than the last one did. Step through the loop to see what happens at each stage.

Step 1 of 9

Observe

Look at the whole tree and its site: canopy, trunk, root zone, and how the space around it is used.

Step 2 of 9

Measure

Record conditions the eye can’t judge well, such as soil moisture and compaction, the same way and at the same marked spots each time, so next year compares with this year.

Step 3 of 9

Investigate

When something doesn’t add up, look deeper: the root zone, the soil profile, or samples sent to a qualified laboratory when the evidence calls for it.

Step 4 of 9

Diagnose or validate

Separate the root cause from the symptoms downstream of it, and keep what we observed, what we suspect, and what the evidence confirms apart. Until a laboratory confirms a problem, we call it “symptoms consistent with” or “suspected.”

Step 5 of 9

Prioritize

Decide which trees and which problems need attention first, and which can safely wait.

Step 6 of 9

Intervene

Do the work the evidence supports. Sometimes that’s pruning or plant health care; sometimes it’s fixing drainage or watering, or simply watching.

Step 7 of 9

Re-measure

Check again, the same way, at an interval that fits the question: soon after a treatment, next season, or at the yearly re-check.

Step 8 of 9

Learn

Compare with the baseline: what improved, what declined, and what stayed the same.

Step 9 of 9

Adjust

Update the plan. New evidence is allowed to change a recommendation, and the loop starts again.

Three kinds of evidence

The value is in connecting them.

A moisture reading without context is just a number. A yellow canopy without measurements is only an observation. Put together, and compared over time, they start to explain what’s going on.

  • Professional observation

    What a trained arborist sees: symptoms, patterns, structure, and the site around the tree.

  • Objective measurement

    Conditions the eye can’t judge well, such as soil moisture and compaction, measured the same way every time.

  • Records over time

    Whether conditions are improving, declining, or holding steady, compared with the baseline.

The evidence covers the whole system a tree lives in:

  • Soil and roots
  • The tree itself
  • The air around it
See how they connect

At every scale

One tree, a group, or a whole property.

A single specimen tree can have its own record. A property with hundreds of similar trees is managed in groups or zones, so the detail goes where it’s worth it.

01
Individual treesA valued tree gets its own number, photos, and measurements.
Groups of similar treesTrees of the same kind, in the same conditions, checked as a group.
ABC
Management zonesAreas of a property managed and sampled together.

Only the tests that matter

Start with a baseline. Go deeper when the evidence says so.

Most trees never need more than a baseline. Each step up happens only when the one before it raises a question worth answering.

  1. For every AIM property

    Baseline

    A documented starting point: standard photos, observations, and repeatable measurements, re-checked every year.

    • Baseline assessment and yearly re-checkStandard photos, tree and site observations, and repeatable measurements, taken at the same marked spots so next year compares with this year.

  2. When the evidence calls for it

    Investigate

    A closer look when the baseline raises a question. Not every tree needs this, and most won’t.

    • Soil and root-zone checksField measurements such as soil moisture and compaction, and a close look at the root zone and root flare.
    • Laboratory testing when warrantedSoil, leaf-tissue, or disease samples sent to a qualified laboratory when the evidence calls for it, with careful records of where each came from.

  3. Where confirmation is possible

    Validate

    Confirming what’s going on, and checking whether the work actually helped.

    • Follow-up after treatmentRe-checking after the work to see whether it helped, and keeping a long-term record for a property or a group of trees.

We don’t run an advanced test because we have the tool. We run it when the result can change a decision.

What you see

The history behind every recommendation.

Instead of being told a tree needs another treatment, you see what we observed last time, the baseline measurements, what was done, what changed, what hasn’t, and what the new information suggests.

Illustrative example, not a client record.

Year one: assessment and correction

  • Reason for the call: Progressive yellowing and thinning in the upper canopy. The client asked for an insecticide application and a nutrient treatment.
  • Symptoms: Chlorosis and undersized leaves in the upper crown, twig dieback, and early crown thinning. Leaf spots consistent with a fungal pathogen, and light activity from insects that typically target stressed trees.
  • Site and root zone: Heavy clay, compacted by foot and vehicle traffic, with poor surface drainage and a buried root flare. At the three marked monitoring points, the soil stayed saturated for days after rain.
  • Soil laboratory test: pH and nutrient levels within an acceptable range, so a nutrient treatment would not have addressed the decline.
  • Suspected root cause: Chronic root stress from saturated, compacted, oxygen-poor soil, which limits the roots’ uptake of water and nutrients. The leaf spots and insects are secondary: downstream effects of a stressed tree, not the cause.
  • Work completed: Surface drainage corrected with a gravel drain; compaction relieved and organic amendment worked into the root zone; root collar excavated; mulch ring installed. The insecticide and nutrient treatment were not needed.

Plan: Treat the root cause, not the symptoms, then re-measure the same points each year. A large, mature tree can take more than one growing season to rebuild its roots and canopy, so recovery is judged over years, not weeks.

Year two: re-check

  • Re-measurement: At the same three monitoring points, the soil now drains within a day of rain, and compaction is lower.
  • Canopy response: Improving. New leaves are greener and closer to normal size, but the upper crown is still thin and some twig dieback remains.
  • Secondary issues: Leaf spot and insect activity reduced, without any spraying.
  • Assessment: Recovering as expected for a mature tree. The root zone has improved first; the canopy usually lags a season or more behind the roots.

Next: No pesticide or nutrient treatment warranted. Maintain the mulch ring, keep traffic off the root zone, and re-measure next year.

Year three: re-check

  • Re-measurement: Drainage and compaction are holding at year-two levels.
  • Canopy response: A full, dense crown with normal leaf color and size, and new shoot growth throughout the upper crown.
  • Secondary issues: Leaf spot and insect activity no longer significant, consistent with the tree’s own defenses recovering once the root cause was corrected.
  • Unchanged: Older dieback on one scaffold limb, from before the correction.

Next: Prune the dead limb. The tree moves to routine monitoring at the yearly re-check.

Who it helps

Landscapes where the long term matters.

When a property manager or board member changes, the record stays with the property, so the next person doesn’t start from zero.

Honest limits

What AIM is, and what it isn’t.

AIM is more than plant health care, a soil test, an inspection, or software. It’s how those pieces connect, from the first observation to the outcome.

  • No single measurement proves a cause. We use several lines of evidence, and a trained arborist interprets them.
  • Recommendations can change as the evidence improves. That’s the system working as designed.
  • AIM doesn’t always end in a treatment. Sometimes the answer is a soil or drainage fix, pruning, planning a replacement, or simply watching.
  • Not every measurement is taken on every property. We match the level of detail to the question being asked.
  • Suspected isn’t confirmed. Until a laboratory confirms a problem, we describe it as “symptoms consistent with” or “suspected.”
