The drought that characterized the first half of summer was broken locally by a series of thunderstorms. The contrast was clear when the time came for the Roger Raccoon Club creek walk at Waterfall Glen Forest Preserve. In the first session there had been no water flowing.
Last week all had changed.
As for the stream corridor marsh at Mayslake Forest Preserve, on Monday I found that dense vegetation was growing in the basin’s damp soil.
Much more rain needs to fall to compensate for what was lost earlier. In the case of the marsh, additional rain will need to exceed the transpiration by all those plants.
