Austin Tree Expert Witness

​

When Evidence Grows in Silence, You Need Someone Who Can Read It

In Austin, trees are more than part of the landscape — they’re woven into the city’s identity. But when a tree becomes the subject of a legal dispute, its beauty fades into complexity. Suddenly, questions of property, negligence, and valuation collide, and attorneys find themselves needing an expert who can translate biology into law.

​

I’m Marty Shaw, a Certified Arborist, Consultant, Author, and Austin Tree Expert Witness. Over the course of my career, I’ve consulted on more than 500 cases across 24 states and have testified as an expert in over 30 legal proceedings. My work focuses exclusively on forensic consulting — interpreting tree evidence for attorneys, insurers, municipalities, and courts.

​

I don’t perform pruning or removal. I deal in facts. My job is to uncover what happened, explain why it happened, and document it in a way that holds up under legal scrutiny. When you retain me as your Austin Tree Expert Witness, you gain more than a credentialed professional — you gain a partner who helps bring clarity, structure, and credibility to your case.

Why Attorneys Retain a Certified Austin Tree Expert Witness

Tree-related cases in Austin are as diverse as the city itself. From construction impact in new developments to storm damage in residential neighborhoods or valuation disputes in commercial zones, attorneys regularly face situations where trees become the focal point of litigation.

​

That’s where I come in. Attorneys contact me when they need answers to questions like:

• Who owns the tree, and who bears legal responsibility for it?

• Was the tree failure foreseeable or unavoidable?

• Did improper construction or pruning contribute to the damage?

• What is the monetary value of the lost tree or landscape?

• Did the property owner or municipality meet their legal duty of care?

 

As an Austin Tree Expert Witness, I evaluate the evidence scientifically and translate it into courtroom-ready documentation and testimony. Attorneys rely on my findings to clarify facts, support or refute claims of negligence, and ensure that technical evidence stands firm under cross-examination.

Understanding Austin’s Unique Legal Landscape for Tree Disputes

Austin’s rapid growth, environmental diversity, and strong local ordinances make it a frequent setting for tree-related legal conflicts. Between municipal protections, urban development pressures, and the impact of Central Texas weather, tree law here carries unique challenges.

​

Common legal issues that involve a Austin Tree Expert Witness include:

• Ownership and boundary disputes — determining who owns the tree and whether trimming or removal was legal under local or state law.

• Negligence and duty of care — assessing whether warning signs were visible or ignored.

• Wrongful removal and valuation — calculating fair market or aesthetic loss for unlawfully damaged or destroyed trees.

• Construction and development conflicts — determining whether excavation, grading, or soil compaction caused long-term damage.

• Insurance and storm damage claims — identifying whether loss was caused by natural forces or preventable human actions.

 

Each of these scenarios demands evidence, precision, and professional interpretation. That’s what I provide.

​

​

Reading the Evidence That Trees Leave Behind

Every tree tells a story. It records history in its rings, bark, and roots — silent witnesses to what’s occurred around it. My work as an Austin Tree Expert Witness involves reading that story.

​

When a case hinges on causation, I examine the evidence methodically. I look for structural failure points, decay patterns, pruning wounds, or soil disturbance. These indicators reveal whether a tree fell from natural causes, construction damage, neglect, or something else entirely.

​

In negligence cases, that evidence might prove a property owner ignored clear warning signs. In insurance disputes, it could establish whether decay existed before a storm. My findings transform guesswork into grounded evidence — the kind that holds up in depositions, mediations, and trial testimony.

​

​

The Central Role of Causation in Tree-Related Litigation

Causation determines liability. When a tree damages property or injures someone, the question becomes: Why did it happen?

​

As an Austin Tree Expert Witness, I focus on identifying that “why.” My investigations include evaluating tree condition, species behavior, environmental exposure, and prior human activity. I document the chain of events that led to the failure, using methods accepted in both arboriculture and the courts.

​

Establishing causation is critical to proving or disproving negligence. Attorneys use my findings to connect physical evidence to legal elements — showing whether the responsible party could have foreseen and prevented the outcome. In every case, my goal is to provide clear, data-driven answers that simplify complex issues for judges and juries.

​

​

Valuation and Damage Assessment in Austin Tree Cases

Austin’s environmental culture places high value on its trees. When a tree is removed or destroyed unlawfully, or when construction causes irreversible damage, that value can and should be quantified.

​

As an Austin Tree Expert Witness, I prepare formal valuations based on the Guide for Plant Appraisal (CTLA), the national standard for tree appraisal. My valuations consider:

• Species, health, and maturity

• Aesthetic and environmental contribution

• Location, function, and property relevance

• Market and replacement cost

• Long-term loss to the property’s character or use

 

Attorneys rely on these valuations to pursue fair compensation or defend against excessive claims. My appraisals are formatted to meet courtroom expectations — transparent, well-documented, and defensible under expert challenge.

​

​

Negligence, Duty of Care, and Standard Practice in Texas

Under Texas law, property owners have a duty to maintain trees in a reasonably safe condition. When a tree fails and causes harm, liability depends on whether that duty was met.

​

As an Austin Tree Expert Witness, I analyze whether reasonable inspection, maintenance, or response would have prevented the failure. I review records, photos, witness statements, and on-site conditions to identify evidence of prior warning signs like fungal growth, cracks, or decay.

​

For plaintiffs, my analysis can demonstrate a clear breach of duty. For defense, it can show that the failure was not foreseeable and that all reasonable precautions were taken. My goal is always the same: to provide unbiased, evidence-based clarity that aligns with legal standards of care.

​

​

Storms, Insurance, and the “Act of God” Question

Few cities face weather volatility like Austin. Heavy winds, droughts, flash floods, and lightning strikes all affect tree stability. After every major storm, insurance claims flood in — and so do disputes over liability and coverage.

​

As a Austin Tree Expert Witness, I help attorneys navigate those disputes. I determine whether damage resulted solely from natural forces or if human factors, such as poor maintenance or prior injury, contributed. Insurers may argue an event was an “act of God,” while property owners may assert negligence or prior defect. My analysis provides the factual clarity needed to resolve those disagreements objectively.

​

In these cases, I often work with both plaintiffs and defense attorneys to ensure that the scientific evidence aligns with the legal burden of proof.

​

​

Expert Testimony: Making the Technical Understandable

In court, the most powerful testimony is clear, calm, and credible. My job as a Austin Tree Expert Witness isn’t to advocate — it’s to clarify. I help the court understand the technical evidence in a way that’s accurate and accessible.

​

With over 30 expert witness testimonies, I’ve appeared in depositions, mediations, and trials across the country. My reports are structured to meet Daubert and Rule 702 admissibility standards. In testimony, I avoid jargon and focus on what the evidence shows — how, why, and to what extent the tree’s condition contributed to the event in question.

​

Attorneys often tell me my ability to simplify complex science for juries gives their argument structure and credibility. When the evidence is clear, the case becomes stronger.

​

​

The Legal Value of Certification and Experience

Certification matters. Courts rely on credentialed experts because they bring verified methodology and ethical accountability. As a Certified Arborist through the International Society of Arboriculture (ISA), I adhere to the ANSI A300 standards for tree care and the CTLA methods for valuation — both of which are accepted across the United States as professional benchmarks.

​

My background as an Author and Consultant adds another layer of credibility. Having served as an expert in more than 500 cases across 24 states, I bring both local insight and national consistency to my work as a Austin Tree Expert Witness. Attorneys know that my methods are transparent, my conclusions evidence-based, and my testimony defensible under cross-examination.

​

​

The Range of Cases That Call for an Austin Tree Expert Witness

I work with attorneys across Austin and throughout Texas on a wide variety of cases, including:

• Property line and ownership disputes

• Negligence and injury claims

• Root and limb encroachment issues

• Construction and grading damage

• Wrongful tree removal and trespass valuation

• Insurance and storm damage disputes

• Municipal liability and code enforcement

• Environmental impact and real estate disclosure cases

 

Each type of case brings unique legal and technical challenges. My role is to uncover, document, and explain the facts that resolve them.

​

​

The Benefit of Early Expert Involvement

The sooner an expert is involved, the stronger the foundation of the case. Early consultation allows key evidence to be preserved and analyzed before it’s altered by time, weather, or cleanup.

​

As a Austin Tree Expert Witness, I often assist attorneys at the earliest stages of litigation to:

• Review case materials for technical merit

• Identify and document physical evidence

• Develop interrogatories and expert questions

• Prepare technical exhibits and graphics for trial

• Provide rebuttal opinions for opposing expert reports

 

Early involvement also helps attorneys evaluate case strength before committing resources to full litigation — saving time and improving strategic positioning.
