Chicago EXPLORING NATURE & CULTURE WSUMIMLERD 19E98 RNES S GEMS OF THE BUG WORLD • P RAIRIES : B ORN TO BURN What is Chicago Wilderness? Chicago Wilderness is some of the finest and most signifi - cant nature in the temperate world, with roughly 200,000 acres of protected natural lands harboring native plant and animal communities that are more rare—and their survival more globally threatened—than the tropical rain forests. CHICAGO WILDERNESS is an unprecedented alliance of more than 60 public and private organizations working together to study and restore, protect and manage the precious natural resources of the Chicago region for the benefit of the public. Chicago WILDERNES S is a new quarterly magazine that seeks to articulate a vision of regional identity linked to nature and our natural heritage, to celebrate and promote the rich nat - ural areas of this region, and to inform readers about the work of the many organizations engaged in collaborative conservation.
