The sound of a good ecosystem

At Railscamp on the weekend, we were surrounded by the beautiful area around Piccadilly. You can see some of the photos on my Flickr stream. One of the things that I noticed though, was the beautiful wetland on the lower end of the property we were on. It had the sign you see below on it.

Frogs

I love this part:

Frogs are excellent indicators of water quality. They’re quite sensitive to pollution, so if they’re around, the ecosystem is probably healthy.

My simple post today is to ask how that applies to what you do everyday and the ecosystem that you’re working in. What does it sound like when it’s healthy? What are the frogs that appear when it’s all going well? And how can you curate your habitat to encourage more of those sounds?
