Neal Smith National Wildlife Refuge, east of Des Moines, IA, was established to restore agricultural land to the tallgrass prairie, oak woodland, and sedge meadow that used to cover the area. Since 2017, staff and volunteers at Neal Smith NWR have tracked phenology of the species that have reestablished on the Refuge - monarchs, milkweeds, and nectar plants - to see whether these migrating butterflies are in sync with their host plants. A new article Fish and Wildlife News details what observers are learning from their Nature's Notebook observations.
