and this rarity has caused them to be categorized as “globally imperilled”. It is estimated that about only less than 0.02% of the original savannas remain due to human interaction and many organizations and conservations are prioritizing restoring and recreating these ecosystems in the midwest. Examples of remnant oak savanna include: Neal Smith Wildlife Refuge near Prairie City, Iowa. Indiana Dunes National Park in Indiana. Hobart Nature District in Hobart, Indiana. Numerous State Natural Areas in Wisconsin. Lake County Forest Preserve District in Illinois. Waterfall Glen Forest Preserve near Darien, Illinois. Cook County Forest Preserve District and Iroquois County State Wildlife Area in Illinois. Oak Openings Preserve Metropark in Ohio. Pinery Provincial Park on Lake Huron in Ontario, Canada. Examples of restored oak savanna sites: Indiana's Conrad Savanna Nature Preserve in north Newton County. Oak savanna restoration project site on Winchell Trail in Minneapolis, Minnesota Wisconsin's Pleasant Valley Conservancy State Natural Area. Minnesota's Belwin Conservancy.
