Midwest Native Seed Preservation Network
A regional network is racing to save the Midwest's native seeds in the face of climate change, habitat loss, and industrial agriculture. The initiative reflects a wider movement toward biodiversity and resilient local ecosystems for conservation-minded gardeners.
Launched by the Chicago Botanic Garden in 2024, the Midwest Native Seed Network connects around 300 ecologists, land managers, and growers from 150 institutions across 11 states. The initiative is a direct response to the massive loss of regional habitats, including 99.9% of Illinois' native prairies. A primary challenge is the lack of available seeds. A network survey found that more than 500 native Midwest plant species are effectively unavailable for restoration projects because they are not commercially grown or are too difficult to germinate. Researchers are now focusing on complex species, such as submerged aquatic plants and parasitic herbs like the bastard toadflax. The loss of native flora directly impacts wildlife, including the endangered rusty-patched bumble bee, which depends on the tallgrass prairies and grasslands that have largely disappeared. Native plants provide essential food and habitat for local pollinators, birds, and other wildlife that have co-evolved with them over thousands of years. The existing seed supply chain faces significant threats from invasive species. In recent years, noxious weeds like Palmer amaranth have been found in commercial wildflower seed mixes sold for conservation, contaminating restoration projects across several states. This effort is part of a wider movement that includes Indigenous-led initiatives like the Upper Midwest Indigenous Seed Keepers Network. These groups work to restore rare, traditional seeds and foodways that were nearly eradicated by federal policies that separated Native people from their land and agricultural practices. The Chicago Botanic Garden's Dixon National Tallgrass Prairie Seed Bank serves as a crucial backup, storing over 100 million seeds from 1,800 native plant species at -20°C. This genetic repository acts as an insurance policy against extinction and provides vital starter seeds for restoration efforts. While the 2021 Bipartisan Infrastructure Law allocated $200 million for the National Seed Strategy, subsequent federal funding cuts have slowed momentum. This has made regional, collaborative models like the Midwest Native Seed Network even more critical for preserving local biodiversity.
