Caption for December 2005 Agricultural Research magazine article, "Conservation: Are We Getting Our Money's Worth?" The late Ron Schnabel (left) and technician Chad Penn collect a water sample from a Pennsylvania stream with both forested and grassed riparian buffers. Schnabel and colleagues proposed focusing on “hot spots,” areas where the most pollution can be stopped at the least cost.

Caption for February 1998 Agricultural Research magazine article, "Natural Environmental Protection Agents." Soil scientist Ron Schnabel (left) and technician Chad Penn check a water sample collected at the outlet of a watershed with both forested and grassed riparian buffers. The impact of riparian zone management on water quality can best be evaluated within streams of treated watersheds.
