When I first saw these amazing landscapes last week, and started photographing them, Invasive Plants were pointed out to me. Some of them have beautiful flowers, like Bull Thistles, and their patches are often the greenest spots around. However, they keep spreading until they choke out everything else. I was told of a thistle patch covering 2,000 acres, and patches can spread by 10% or more each year.
