Coming onto a new property offers any superintendent a fresh perspective that is hard to have when you have been at the same property for along time. This is my experience anyway. This past year at my new course I have really noticed the differences in turf species composition and have thought a lot about why this may have occurred. The more I think about it the more my way of thinking about species composition and overseeding practice have changed. Let me explain. Poa likes high traffic areas more than other turf species, or does it? Take a look at the following picture of one of our greens from above. You can see the patch of yellow turf behind the green. This is disesased poa annua coming out of winter. There is a pretty uniform patch of poa behind this green on a slope that experience high traffic stress from mowers turning and golfers walking. There is no denying that this poa is here because of high traffic stress but is it here because it is a better suited turf species for this
