Prairie remnant

Prairie Remnant Near Chicago Illinois

A prairie remnant commonly refers to grassland areas in the western and midwestern United States and Canada that remain to some extent undisturbed by European settlement. Prairie remnants range in levels of degradation but nearly all contain at least some semblance of the pre-Colombian local plant assemblage of a particular region. Prairie remnants have become increasingly threatened due to the threats of urban and suburban development, pollution, fire suppression and especially the incursion of invasive species.
