Wisconsin Natural Areas explores wild and tame lands in “this place we call Wisconsin.” During the Pleistocene epoch, a continental glacier sculpted and modified the land, sans southwestern Wisconsin’s Driftless Area. This most recent Ice Age produced regional landscapes with contrasting ecoregions that underpin the state’s natural areas. Among the topics to be examined are ecological landscapes, Public Land Survey System, WDNR State Natural Areas Program, land ethics, ecosystem services, invasive species, natural areas restoration, and Wisconsin natural communities.
