Golf courses are close to ideal iguana habitat: acres of tender, fertilized turf to graze, water hazards and lakes for escape and drinking, and soft open banks that are easy to burrow into. The damage shows up as grazed greens and tee boxes, droppings on playing surfaces, and burrows that collapse bank edges and undermine cart paths, bulkheads, and irrigation. On a course, the animals have everything they need and very few reasons to leave.
Prevention on a course is fundamentally a scale problem. It centers on controlling burrows along the water-hazard banks, targeted removal of the resident population, and scheduled monitoring so the crew stays ahead of the breeding cycle rather than reacting after greens get chewed. Superintendents generally want a routine program tied to the season, not one-off calls after damage is already done.
Where the damage concentrates
On most courses the trouble clusters in predictable places, which is what makes a scheduled, hole-by-hole program workable rather than overwhelming.
- Greens and tee boxes — grazed tender, fertilized turf
- Water-hazard banks — burrows that erode and slump the edges
- Cart paths and bulkheads — undermined by bank tunneling
- Playing surfaces — droppings that are a maintenance and image issue
Fitting the work around play
The practical constraint on a course is that you can't disrupt rounds. Monitoring and removal are scheduled around the operation — typically early mornings or off-peak windows — so the work fits between play rather than interrupting it. A good program is planned by hole and by season so the crew is systematically staying ahead of the animals instead of reacting to complaints from the pro shop.
Common questions
Can prevention keep greens and tees from getting grazed?
Reducing the resident population and controlling the bank burrows near play is what protects the turf. On that much open water and turf it's about steady, scheduled pressure, not fencing every green — a fence around each green isn't practical on a course, so the strategy is population control at the banks.
Does this interfere with play?
It shouldn't. Monitoring and removal are scheduled around the course's needs — typically early or off-peak — so the work fits the operation rather than disrupting rounds. The program is planned to be invisible to golfers as much as possible.
Why do burrows matter as much as the grazing?
Because bank burrows do structural harm beyond eating turf — they erode and slump hazard edges and undermine cart paths, bulkheads, and irrigation. Grazed turf recovers; a collapsed bank or an undermined cart path is a real repair. Controlling the burrows protects the course's infrastructure, not just its appearance.
