Honeysuckle is killing forests and ivy is helping, especially in the northeast/midwest. Kill all that shit, help stop it from spreading. And try to volunteer for local groups that are clearing invasive species. It’s pretty amazing seeing a forest before and after invasive species have been removed.
He also once had a student go ahead and plant a tootsie roll molded to look like scat on a rock so that we could come upon it and watch him take a bite to “determine what kind of animal it was from”.
Gotta love the dedication to the bit.
