These are real pages from the book. The table of contents is the full one: 9 parts and 65 topics.
You're at the site trailer and the contractor wants to know where the excavator can't dig. You know the roots are out there. Now you have to say how deep and how far.
The textbook covers root distribution in page after page of prose: absorbing roots, lateral spread, soil oxygen. You read it at night after a full day in the field, and by morning it's gone.
In this book, roots get one page. A cutaway of the tree and the soil, with most fine roots in the top 12–18 inches, spreading well past the dripline, all labeled so you see it in one look.
Same with CODIT's four walls, the soil texture triangle, the two risk matrices, the TPZ and shall vs. should: each one has its own page.
You understand it, and you explain it on site without going back to the textbook.
Tree biology, wood and decay, roots and soil, diagnosis, risk assessment, trees on construction sites, pruning and support specs, consulting and safety, and the exam-day review: 69 pages, all illustrated.
Think of it this way:
A city forester asks why you rated the likelihood of failure 'probable' and not 'possible'. You need the framework clear, and in the right order.
You open the risk page and see it drawn: failure, then impact, then consequences, the two matrices filled in, one arrow leading to the next.
Same with CODIT, the soil texture triangle, the 5 diagnostic steps, the TPZ sized from DBH and the three pruning cuts: each on its own page.
Arborist Illustrated: Master Level is 9 parts and 65 topics, all drawn, and it ends with an exam-day review: the numbers, the terms that get mixed up and the checklists.
What you see drawn, you don't have to memorize.
Leaves, wood and roots as one system, the energy budget, cohesion-tension, stored carbohydrates, growth regulators, wood types and stress responses.
See which CODIT walls are already in the wood and which forms after the wound, plus branch collar, woundwood, and brown, white and soft rot side by side, so you can tell them apart in the field.
Where roots really are, mycorrhizae, the soil texture triangle, compaction, available water, pH, CEC and how to read a soil test.
The 5-step diagnostic method one step at a time, plus vascular wilts, major pests and IPM with the label.
Rate risk the same way every time: likelihood of failure and impact, both matrices filled in, targets and occupancy, decay numbers, advanced tools, and mitigation with residual risk.
Give the contractor a number: CRZ vs. TPZ, the TPZ sized from DBH, fence specs, cut and fill, trenching vs. tunneling vs. air excavation, root pruning and a protection plan by phase.
Pruning objectives, the three cuts, how much and when, structural pruning, cabling and bracing, lightning protection and planting to spec.
Shall vs. should, the arborist report section by section, observations vs. opinions, appraisal, urban forest management, Z133 and rigging forces.
The numbers to have at hand, terms that get mixed up, frequent errors in reports and specs, the checklists and a plan for the last 30 days.
At the end of the book: An exam-day review: the numbers to have at hand, terms that get mixed up, and the diagnosis and risk checklists.
Exam-style questions on every chapter, each answer explained and linked to the page it comes from, so you find your weak spots before exam day.
The steps, numbers and definitions you need to have at hand, one card per topic, to review in ten minutes the night before or print and keep in the truck.

Yes. It isn't a beginner book: it covers advanced topics like CODIT, soil chemistry, risk matrices, tree protection plans and spec writing. It puts in order and draws what you already half know from the field.
From ANSI A300 (2023 edition) for pruning, soil, support, construction and risk, ANSI Z133 for safety, the ISA Best Management Practices and the published content outline of the Board Certified Master Arborist (BCMA) exam. Each page cites the standard and its edition, so you can check it against the current one.
No. It's an independent study guide, not affiliated with ISA or any certifying body. It doesn't give you a certificate, a credential or CEUs: it's for studying and reviewing.
No. It helps you review and organize the content; the official references and your field experience still come first.
