My lawn (that I love) is not a mono culture. The parts I planted are dominated by the grass I planted (fescu? sp?) but the invasive flowering weeds are encroaching and I am happy to see them. Biggest influence is foot fall. High traffic areas are very different from low traffic areas. I imagine my lawnmower is like a herbivore eating the tops. I have experimented with letting it grow. Gets dominated by dock and long grasses generally
