Volo Bog State Natural Area (SNA) is located in northern Illinois in the town of Ingleside (Figure 1). It was nominated and accepted by Society of Wetland Scientists as a Wetland of Distinction for its unique and exceptional qualities discussed below. Perhaps, most importantly, it is the southernmost open-water quaking bog in North America to exhibit all stages of bog succession and Illinois’ only remaining open-water quaking bog; hence meeting the WoD metric of rare/unique wetland type within its own biogeographical region. Volo Bog provides habitat for biologically diverse wetland flora and fauna. It is recognized locally as an Illinois Nature Preserve and nationally as National Natural Landmark. Interpretive staff and volunteers organize and provide a plethora of educational outreach and management opportunities for the public. While largely now protected due to state protection, ecological threats include non-native species and an adjacent concrete recycling facility that impacts the site with noise and particulate pollution. Surrounding neighborhoods currently are low density.
