Wondering Naturalists

Jon and Lynn are two sixty-something, retired, PhD ecologists seeking the wisdom from the natural world that can only come from first-hand experience with things and events.

Development in the desert

Tucson, as with Phoenix, is growing rapidly and many fear depleting its water supply and threatening natural areas. In some places, water tables have dropped 150 ft. in less than 30 years. Obviously, this cannot continue.
