What advice would you give to beginning naturalists?
In addition to getting a strong educational foundation at a college or university that specializes in natural sciences, I would say that it is equally important to spend time outside observing and learning to identify the plants and/or animals you are interested in. And you do not have to go very far away to do it. While it might be exciting to travel to far-off places and study exotic plants and animals, many of the great naturalists of the past have not traveled much farther than their own backyard. You can learn a lot by just watching the birds at your backyard feeder or the insects in your garden.
What are your favorite natural areas in Iowa and the Midwest? What areas do you return to constantly?
Although many non-Iowans do not realize it, we have some wonderful natural areas in Iowa, including our state parks and state preserves. I enjoy the forests and limestone bluffs of northeast Iowa. For seeing the largest variety of reptiles and amphibians, southeast Iowa is the place to visit. The wetlands and Mississippi River backwaters in this part of the state are home to more different species of reptiles and amphibians than any other part of Iowa, which is why the Iowa Department of Natural Resources designated a portion of seven counties in southeast Iowa as an Amphibian and Reptile Conservation Area. For many years I have been spending a great deal of time along the Upper Wapsipinicon River in Bremer and Chickasaw counties.
