| Maumee River at River Road and Jerome Road | This unique area of the Maumee is actually a very rare biological environment called an alvar - a limestone plain with thin or no soil that results in sparse grassland vegetation.  Often flooded in the spring, and affected by drought in midsummer, our Maumee River alvar supports a distinctive group of prairie-like plants, lichen, and mosses. Most alvars occur either in northern Europe or around the Great Lakes in North America.  We are very fortunate to have this distinctive environment in our back yard.
