IPAW Working List of the
Invasive Plants of Wisconsin

Figure 3.Ecoregions as defined on the IPAW-GLIFWC non-native plant survey. 

Ecoregion boundaries are identical to those on the survey, but the ecoregion identifiers have been recoded.  Ecoregion codes are the same as those used in Appendix 1.  All seven of the defined ecoregions extend outside of Wisconsin.  Only a small portion of the Illinois (IL) and West-Central (WC) ecoregions extend into Wisconsin.
