Prairie remnants along Wisconsin highways

The original Wisconsin highways were cut through vast acreages of remnant prairies. Of course, once a highway is created, development follows.

The information below came from the Wisconsin DOT web site, which can be reached at this link. I reformatted the table to make it more legible.

I don't guarantee that all of these remnants still exist, although even without restoration work or burns a few more vigorous prairie species may still be present. I have only been to a few of them. I have been watching the remnant west of Cross Plains for many years, where prairie dock and a few other species have been able to hold their own among onslaughts of wild parsnip and spotted knapweed.

Note that the data are only from Wisconsin or U.S. "numbered" highways. There are lots more remnants on county and town roads.

If you visit any of these sites, park carefully and keep an eye out for traffic!
