We stood in the middle of a small forested region on the UW campus next to the medicinal herb garden. The forest consisted of many different types of trees including: Douglas fir, Western Hemlock, Big leaf male, Western Red Cedar. The ground cover was mainly covered in english ivy with the occasional patch of sword fern and oregon grape. In the tall, leaf-less trees above, we observed many nests belonging to great blue herons. We witnessed a male heron attempting to mate with a female but was driven away by another, more dominant male heron.
