Olson Ecological Solutions (OES) is a woman-owned ecological consulting and restoration firm, serving federal, state, local, and private entities in the Upper Midwest Region. We specialize in wetlands, water quality of streams and lakes, and restoration of high quality native remnants and natural areas. We deliver solutions that provide natural storm water filters in rural and developed settings, such as rain gardens or constructed wetlands, including in river corridors, drainage systems, parks, and neighborhoods. The consultants at OES spend most of their time preparing watershed-based plans to prevent nonpoint source pollution from entering our streams and lakes, completing wetland delineations and the associated permitting, and designing best management practices (BMPs) and green infrastructure related to stormwater runoff. The restoration crew stewards natural communities in public open spaces, wetland mitigation sites, and forest preserves in the Chicagoland Region. Restoration Technicians spend most of their time removing invasive species and encouraging the growth of native species in established and restored natural communities.
