Ram's-head habitats are a place where many plants would be starved. The sandy soil just doesn't have many nutrients, and it's a little acid. That doesn't mean it's not a great place to look for wildflowers. The ram's-head spot I was in at Wilderness Park had dwarf lake iris, calypso orchids, fringed polygalas, and other fun stuff. The lichens provided good backgrounds. The greatest threat may be photographers. I wasn't the only one that day. But everyone seemed pretty careful about feet and equipment.
