St. Paul is located in the Upper [[Boston Mountains]] ecoregion. The ecoregion is generally higher and moister than the Lower Boston Mountains; elevations vary from {{convert|1900|to|2800|ft}}. Potential natural vegetation is [[oak–hickory forest]]. Characteristically, the forests of the Upper Boston Mountains are more closed and contain far less pine than those of the Lower Boston Mountains. North-facing slopes support [[Mesic habitat|mesic]] forests. The region is underlain by [[Pennsylvanian (geology)|Pennsylvanian]] [[sandstone]], [[shale]] and [[siltstone]] that contrasts with the [[limestone]] and [[Dolomite (rock)|dolomite]] that dominates the [[Ozark Highlands]]. Water quality in streams reflects geology, soils, and land use, and is typically exceptional; mineral, nutrient, and solid concentrations as well as [[turbidity]] all tend to be very low. During the summer, many streams do not flow.<ref name=ark4>{{USGS|title=Ecoregions of Arkansas|comment=color poster with map, descriptive text, summary tables, and photographs |last1= Woods|first1=AJ|last2=Foti|first2=TL|last3=Chapman|first3=SS|last4=Omernik|first4=JM |display-authors=etal | url=ftp://ftp.epa.gov/wed/ecoregions/ar/ar_front.pdf }}</ref> The timber industry was once a source of many jobs.<ref>{{Cite web |title=Saint Paul, Arkansas History |url=http://bostonmtsjournal.com/saint-paul-arkansas-history/}}</ref>
