The old frog pond was little more than a ditch, dug when the driveway was built. After a flood several years ago, we had to rebuild a large section of the driveway, and where earth and rocks were taken for that purpose, a new pond formed, organically.
We weren't aware that it was happening, but frogs and dragonflies and fireflies found it, and flowers grew around it.
A new ecosystem grew.
This week, among the abundance of daisies I found a lone foxglove.
The water in the nearby brook runs clear, but the frog pond relies on rain, and is filled with strange clumps of matter in various stages of growth and decay--good camouflage for a frog resting on a stick.
I wrote a bit about frogs and ecology here. I am always relieved when I walk to the pond, and find that the frogs are still there.
