URBANA, Ill. — Illinois is home to 21 different native oak species whose populations provide habitat and food for wildlife, support biodiverse ecosystems, contribute to improved air and water quality, and provide residential shade benefits that help to reduce energy use.

Gain a better understanding of this majestic, deciduous tree species, explore oak ecology and range, and learn how to identify Illinois' 21 native oak species in a free online workshop led by Chris Evans, University of Illinois Extension forestry specialist.

“Oaks are one of the most important plant groups in Illinois,” says Evans. “By learning to identify and care for oak populations, homeowners, forest owners, and tree care professionals can support a diverse and ecologically significant environment, both in residential and woodland areas.”

The session will be held online from 1 to 4 p.m. on Oct. 19, including interactive elements and opportunities for review and participant questions. Tree care industry professionals can earn Continuing Education Units from the International Society of Arboriculture for participating.
