Stringency of county zoning ordinances and land-use plans in counties with higher- and lower-than-expected mine counts in county-zoned areas.

aBased on multi-county neutral model analyses for counties that were entirely under county zoning, Trempealeau and Buffalo (Fig 3), and within-county neutral model analyses for all other counties (Table 1).
bFrom [76]. Standards include those either required or considered during the conditional use permitting process, as named in the county’s zoning ordinance [76] (see S1 Appendix for full list of standards).
cFrom [77]. Land-use plans were scored based on mentions of nonmetallic mining, ordinances and policies, and goals, as well as language strength [77] (See S1 Appendix for score equation).
dFrom [78]. Number of nonmetallic mining standardsb and land-use plan scorec were normalized and added to get a combined stringency score [78] (See S1 Appendix for detailed methods).
