The Untold Story of the Five Pollinator Plots on I29
South Dakota’s rural landscape is a patchwork of agriculture and urban development that has fragmented native prairie. As a result, many species are funneled into narrow migration corridors along roadways. Rest-area landscape “nodes” can strengthen these corridors by providing diverse habitat that offers food, shelter, and nesting opportunities.
IMEG’s Paul Clinton, PLA, has played a leading role in developing and monitoring the Pollinator Habitat Plots at five South Dakota Department of Transportation (SDDOT) rest areas along the I-29 corridor in eastern South Dakota. These sites are designed to create and expand habitat for monarch butterflies and other pollinators by establishing essential resources on state-owned land, aligned with the South Dakota Monarch Conservation and Management Strategic Plan.
Collaborating closely with SDDOT and contractor, Paul addresses the real-world challenges of implementation and long-term stewardship. Management strategies balance available tools and techniques to minimize impacts to pollinators while effectively controlling invasive and noxious weeds through thoughtful mowing and herbicide recommendations.
The project applies science and technology approaches grounded in plant science, ecology, landscape performance, and site assessment. Prairie ecology guided the original seed mix and subsequent adjustments tailored to site-specific conditions. Plant identification helps distinguish desirable native species from invasive, while Floristic Quality Assessment (FQA) is used to evaluate plant composition and overall ecological integrity. A drone platform was introduced to the monitoring process to count milkweed plants annually.
This presentation highlights lessons learned, and the rewarding process of restoring, preserving, and reintroducing prairie landscapes on approximately 75 acres.
