A Trail of Three Wetlands

I had quite a weekend attending the first two of 13 events scheduled for this year's 13th Annual “Explore the Nature of Knox County" program. 

On Saturday, I went to the "Trail of Three Wetlands" at the Brown Family Environmental Center and learned more about the vernal pool I had been monitoring for salamander and other amphibian breeding migrations.  Tour leader Siobhan Fennessy, co-director of the Brown Center and a Kenyon biology professor, showed us the eggs of spotted salamanders laid on rocks underwater, proof there had been a spotted salamander migration that I missed.  She said there is concern that vernal pools are on the decline because of tree cutting and other land management changes, which could be very harmful to amphibians, especially salamanders.

She also said concerned landowners can create vernal pools by excavating in the right locations.

The other two wetlands were a skunk cabbage seep fed by the downhill flow of groundwater and a wet meadow that was restored by fencing out cattle.

Sunday's event was at the Ramser Arboretum, a nature preserve about 10 miles from Apple Valley and open to the public.  I'll write about that later this week, along with a related preserve on Proper Road, even closer to Apple Valley.
