* I had the same thought about vernal pools at the CARCNET meeting at
Quebec City in 1999, during a presentation on Marbled Salamanders, which
come down into the vernal pools to lay their eggs on the dry pondbed in
the fall, and stay with them all winter. It turns out that the vernal
pools fill from the water table, as one would think sandy dunes would.
And yes, I've been monitoring water level in our local Wood Frog ponds,
fall and late winter, ever since then.
