Agroecology Research Team

1991 - 2002

Purpose

This research team studied riparian buffer systems and operated the Bear Creek Watershed Demonstration Project. The highly successful, award-winning program worked with landowners in the Bear Creek watershed to install riparian buffers to mitigate erosion, reduce nitrate runoff and improve wildlife habitat. The Leopold Center supported the group from 1991-2002, and it continues to operate.

Team members included farmer/landowner cooperators, Iowa State University scientists, and professionals from state and federal agencies and non-governmental organizations. The team was led by Bruce W. Menzel and Richard C. Schultz of Iowa State University.

The goals of the Agroecology Research Team:

• to assess the impacts of agricultural practices on the structure and function of regional agroecosystems
• to design and test small-scale agricultural landscape management systems that can lessen negative environmental impacts of agriculture and enhance natural ecosystem function
• to develop a holistic approach for reconstruction and/or restoration and management of regional agroecosystems that are environmentally sound, socially acceptable and economically feasible
