The community shall provide the most up to date appendix to the DNR and FEMA regional offices. Understory composition is also quite variable and follows the pattern exhibited by the canopy species-the most extensive stands and highest plant species diversity occur in southwestern Wisconsin. Existing large blocks and connectivity should be maintained where possible (e.g., along the Wisconsin, Chippewa, Jump, Yellow, and Black Rivers), and managed as part of a mosaic of other forest communities.
