Field-Based Learning at the Stroud Center’s New Outdoor Classroom

There’s just something about going outside. It’s fun. It lowers stress levels. It helps students focus. And it’s a great way to learn about freshwater science. For these reasons and more, we’ve made field-based learning an integral part of our education programs — now enhanced by an engaging outdoor classroom that lets visitors explore White Clay Creek, the research stream that runs behind our offices.

Cover Cropping Series Starts

Sunn Hemp Acts as Covered Bridge Between Sweet Corn, Broccoli is the first of three columns about farmers who are being coached by cover crop innovator Steve Groff. Supported by the Stroud Center, the series builds on our ongoing work with farmers and landowners to protect, restore, and monitor the long-term health of streams.
