May 2021

Randy Nyboer, former District Natural Heritage Biologist for the Illinois Department of Natural Resources and Endangered Species Program Manager for the Illinois Natural History Survey, will lead a virtual tour of the rare flora of Apple River Canyon and the new Townsend Glade Land & Water Reserve. The video will be presented during a live Zoom meeting and will be posted on our website to watch after May 20.

The Natural Land Institute acquired the 149-acre Townsend Glade property in 2018 and designated it as an addition to the Apple River Canyon Land & Water Reserve in September 2020. The rare flora and unusual cliff communities of the Apple River Canyon in eastern Jo Daviess County have been recognized for more than 100 years. It’s unique geology and high-quality natural communities support 13 species of rare and endangered plants, including the only known population of Bird’s-eye primrose in Illinois. The Townsend Glade property has wet and dry dolomite cliffs that support the state-endangered white camass (Zigadenus elegans) and two state-threatened species, cliff goldenrod (Solidago sciaphila) and Sullivantia (Sullivantia sullivantia). Stands of native white pines and Canada yew grow on the bluffs along the canyon.
