Dr. Rick Machen
Professor & Extension Livestock Specialist
We have a divine responsibility to be stewards of the land, whether entrusted with a small lawn or thousands of acres. Regardless of the primary focus – plants, animals or people – natural resource managers share a common interest in the protection and well being of the soil and water resources. Though my primary focus is beef, lamb, goat and fiber production, I also maintain a keen interest in wildlife and watershed management.
Above and beyond natural resource stewardship and management is an even greater responsibility – the education and mentoring of the next generation. Nothing excites me more than the opportunity to share my learning or a life experience with a few of tomorrow’s leaders.
