Mike, it is significant to mention that Sand Hills has now been grassed for nearly 20 years and in that time they have had periods of turf issues. The sward has been overtaken by poa and then reclaimed with fescue and it has been a dance orchestrated by two highly competent and respected turf managers in the past. Not to mention the wind erosion. All sand hill courses undergo these turf challenges in their respective micro environments. As for Bandon, it is a climate different than Deal and the Pac Norwest is notorious for ripe conditions of poa proliferation at a rapid and unmanageable rate.
The time window to deal with turf species management and cultural practices is also vastly different, particularly considering the short golf operational season, timed with short window to halt golf inorder to deal with macro turf treatments and species management.
I'm not a turf expert but I do know that it is not a proper comparison to say that one of these courses can manage better or more successfully in their cultural and turf species management and invasive suppression than another. They all have the goal of business success or viability, obviously. I think the very nature of economic self interest will cause their professional staff and decision makers to try various approaches, always experiment with new ideas, and seek the best and highest practices that support their business success. That is why they are the professionals they are. And, they do collaborate and share ideas in their turf professional circles, whether it is a circle formed in a tavern or a symposium organized by state and national turf professional orgs. None of these big time golf resort complex venues employ chimps for turf managers, they'll keep working to give you the best experience possible within the environmental and climate challenges they must cope with.
