Removing Trees Does Not Make a Golf Course Easier: Aronimink Has Answered, Pebble Beach Waits Until 2027

When the scoreboard closed at the PGA Championship at Aronimink, the champion finished a few strokes under par. Weeks earlier, golf commentary on social media had already reached its verdict: the course would play like a stroll. The reason was neat — hundreds of trees had been removed from Aronimink during a restoration of the original design. Remove trees, open up space, return the course to its original state. It sounded like a formula for turning a major into a birdie festival.

The leaderboard did not follow that script. It spread wide, with multiple groups contending through the back nine on Sunday, and the winning score stayed in single digits under par. A course labelled "too easy" produced no one who reached double digits under par over four days.

Context: two trees, two stories blended into one

Aronimink was a large-scale restoration. Hundreds of trees were removed to recover the original design intent of the course. When a course reopens space that trees had swallowed, the eye watching on television immediately sees wider fairways, sees emptier golf holes, and the brain automatically translates that into: easier.

Pebble Beach sits in a fundamentally different situation. A cypress on the property had become diseased. According to the statement Pebble Beach sent to Golf Digest, the tree had been treated for roughly two years, and a certified local arborist recommended removal because of the disease and the associated risk. This is an asset-maintenance decision, not a design decision.

On the internet, the story was retold in another direction. Videos claimed the removal was a USGA decision ahead of the 2027 U.S. Open; others said it was a strategic move engineered by Pebble Beach itself. Neither explanation matches what the course and the arborist made public.

Pebble Beach is no stranger to replacing trees. After the 2026 ice storm, the iconic tree near the finishing hole had to be replaced. The course holds a fairly clear principle: preserve visual identity. Ahead of the 2027 U.S. Open — Pebble Beach's seventh time hosting — tee, bunker and green work is planned, but the venue has said its familiar character will be retained.

Justin Thomas was the most-quoted name in the wave of reaction. He wrote that removing the tree "makes no sense to me," and asked when places will realise that getting rid of trees is not the answer to making courses better — adding a "haha" at the end.

Based on my experience following tournaments, I always separate two kinds of opinion about a golf course: opinions about image and opinions about difficulty. They are usually merged into one, and that is the source of almost every argument of this type.

Analysis: why removing trees does not lower difficulty

Whether a course plays hard or easy is decided by a measurable set of variables: green speed, rough height, course length, pin positions, wind speed and direction, firmness of the fairways. Trees affect only part of that set — mainly by blocking wind and shaping flight corridors.

When a line of trees is removed, difficulty does not vanish. It relocates. More wind on the property means balls pushed off line at height, and players must recalculate every iron in the bag. Wider fairways mean different angles of attack, and hard pin positions remain hard, sometimes harder because there is no longer a reference point to help the player aim. The Aronimink restoration returned the course to its original design intent — and the original designs of classic courses were usually calculated around the ground, around slopes, around running ball paths, not around forests.

At Aronimink the results reflected exactly that. The leaderboard was scattered, with no small group breaking away. The winning score sat in single digits under par. For a major, that is evidence a course has lost none of its pressure.

A trophy does not measure strength; it measures a collective's capacity to endure chaos. At Aronimink, that collective was more than 150 players facing a course whose wind structure had changed, and most of them never found a stable level lasting beyond a single round. If the course were genuinely easy, someone would have broken away to double digits under par.

What stands out is that the critics themselves implicitly concede the course matters. Aronimink was rated as a medium course fit for the modern field — meaning it favours no single club type, no single driving style, no single player type. The variety on the leaderboard is a direct consequence of that.

Every crisis begins with a number left out of a financial report. In this story the report is not a balance sheet but an arborist's assessment. The overlooked number is the treatment period — two years — before a removal recommendation was issued. Nobody cuts a mature cypress on an iconic golf course because it looked tilted one morning.

Ahead of the 2027 U.S. Open, Pebble Beach will also adjust tees, bunkers and greens. Those adjustments matter far more than a single tree, because they touch directly on how the course plays at the holes where scores are made or taken away. But that is work within the venue's and organiser's remit, and it rarely gets published in sensational terms.

The counterintuitive angle: fear of losing trees is fear for the brand, not for difficulty

Reading the reaction wave closely, most of the energy sits not in concern over scores. It sits in concern over image. Pebble Beach sells tickets and sells television largely through its landscape: the ocean at the 18th, tree trunks casting lines along the boundary, a frame viewers recognise in a single second. A tree disappearing from that frame is a visual change, and for a brand built on the visual, a visual change is felt as loss.

Another point deserves mention. Justin Thomas is a major champion, and his statements carry far more media weight than those of an average player. But the way he wrote it — a rhetorical question with a laugh — shows an immediate reaction to a photograph, not an architectural argument. The information available to him at the time of posting did not include the tree's diagnosis, nor the two years of treatment.

A great champion is not someone who never falls, but someone who knows exactly when he is about to fall and prepares a controlled fall. The same applies to classic golf courses: they cannot avoid change, they can only choose which change is properly prepared and which is forced by public opinion.

The biggest risk here is reputational and public-opinion based, at a medium level. The course faced criticism, but it proactively issued a statement grounded in expert assessment. This tends to settle within less than a month, until the next photograph appears.

The more worrying part sits on the public side. False claims about the USGA's role, about Pebble Beach's "strategic design," travel far faster than an arborist's report. At that point, a golf course is judged by people who never read the source document.

A thought to leave behind

For the 2027 U.S. Open, the question worth dwelling on is not what the USGA will do to Pebble Beach. It is whether the crowd will wait until the tournament ends before passing judgement on a golf course. Aronimink has already played and given its answer: removing trees does not lower difficulty, it simply moves difficulty elsewhere. Three years from now, Pebble Beach will get the chance to answer in the same way.
