King Ranch Bluestem (KR) is commonly the dominant bunch grass of open fields in N. Hays County, especially those that were intensively grazed until recently. This exotic Eurasian species, introduced for grazing and as a roadside grass, has proven to be an unwelcome invasive addition to the hill country flora.
The Hurlbut cattle continued to graze our property, stopping only when, with the help of James Hurlbut, I fenced them out in late 1977.

But intensive grazing stopped in early 1976, and KR soon began to flourish in all open areas — even with occasional visits by the cattle. Cattle control at that time was achieved by chasing them a half mile down the valley. But eventually they always returned until the fence was in place.
KR attempted to dominate even on the arid upper plateau with very shallow soil. The picture below was not taken to document this, but the tall, straw-colored grass at the far end (at the fenceline) is KR.
