These two pictures are both from the intramural field on ISU campus. The first one is from last November. It shows a strip of warm season grasses that have been planted on the steam tunnel that runs through the area. They include bermudagrass, zoysiagrass, and buffalograss. They are all dormant as would be expected in November. The Kentucky bluegrass/perennial ryegrass turf is green.
Now look at this picture taken yesterday, Aug. 23, 2010, approximately two weeks after the flood. This area was completely under water for at least 3 days. The bluegrass/rye is dead (although I think the rhizomes of the bluegrass are alive) and the warm-season grasses have recovered. This is a good demonstration of how well warm-season species can take flooding.
