This image is looking upstream from where the green violet grows.  This area is only about four miles north of the Ohio border.  It is home to a significant number of Michigan rare plants.  That may have relatively little to do with the habitat, and more to do with the Michigan-Ohio War.  1000 militia from Michigan occupied Toledo.  600 from Ohio took up posts just south of there.  Both governors were present.  And we're not talking about football.  In 1835-36 there was a dispute between the states over a strip of land the included Toledo, Michigan.  Yeah, I know, we lost that one.  We also lost a lot of habitat that includes those rare southern Michigan plants.  Had we not lost that area, those species would be a lot less rare in Michigan.  The other historical event that impacted plant distribution in the area was the last glaciation.  The southern limit of glacial deposits is near this border.  Habitats north and south of that limit are somewhat different.  South of it was once a huge hardwood area called the Great Black Swamp.  North of it are glacial deposits leading up to Michigan's Irish Hills.  Did Michigan lose the war?  You decide.  We lost the Toledo strip, but gained the Upper Peninsula, and an awful lot of interesting plants up there.
