Prairie strips are a farmland conservation practice that uses strategically placed native prairie plantings in crop fields. The practice has been tested by the STRIPS team since 2007 on experimental plots at the Neal Smith National Wildlife Refuge and increasingly on commercial farms across Iowa. The information was prepared by team members, and will be updated over time as needed, as we continue to learn. The answers below are general in nature, and may not apply in specific situations. Resources are provided with each answer.

  • Iowa State University Research and Demonstration Farms hosts several commercial scale implementations of prairie strips that are open to the public during business hours.
  • Iowa Tallgrass Prairie Center hosts how-to information on prairie establishment and management. See the 'Prairie On Farms' project.
  • Plant Iowa Native links to dealers where prairie seed may be purchased and to technical service providers who can help with prairie installation and management.
  • Neal Smith National Wildlife Refuge has a mission to actively protect, restore, reconstruct and manage the diverse native ecosystems of tallgrass prairie, oak savanna, and sedge meadow. Educational opportunities are available throughout the refuge, but the Prairie Learning Center is a good place to start. The refuge hosts the original STRIPS research experiment.
