It said that they pledge not to seed but to simply mow the native grasses. Is there any chance that could lead to a nice playable surface in that area? Are there any other courses that have never seeded?
I mean back in the day that's what everyone did. Sunningdale, in 1900, was the first course to be seeded. Huntercombe, built at the same time, was mowed out from the common land grasses that had been there for centuries. It will work fine, it is just likely to take time to refine the surface, especially given the other commitments about not using chemicals. If the course goes ahead, I expect it to be an old skool process -- it will not debut in fantastic condition, and will take time to get right. I think Machrihanish Dunes was the most recent course that was mowed out, and it took a pounding in its early days, partly because the condition was not as modern golfers expected. Coul will almost certainly be the same. If it happens, which is by no means certain, as Marty implies.
It's also interesting to note that the project's backers have pledged to collect seed from the native grasses and use that seed to repair divots, so no non-native grasses will ever find their way onto the golf course.
