Those features were not the reason for the photo, however, which was taken because of an insect that requires a zooming in to see.

Some Early July Flower and Insect Sightings at Herrontown Woods
Necessary for the prospering of these summer wildflowers is an opening in the tree canopy where sunlight can reach the ground. Though people often equate habitat health with trees, we actively remove many young trees in the Barden that would otherwise grow up to shade out all these herbaceous species that insects depend upon for summer sustenance.
The take-home lesson here is that woodland openings are important for summer biodiversity. Given the lack of natural disturbance by wildfire or the long-gone megafauna, it's up to us to create and sustain it.
