Most people think of urban sprawl as the construction of roads and buildings at a rate that exceeds population growth. Phoenix, Arizona, however, offers a contrasting model of sprawl. Its metropolitan area has grown more than 300 percent in recent decades, but its population has grown even faster.

This trend is by necessity, since the water supply cannot feed an ever-expanding metropolitan area.

Today, landscape ecologists are reconstructing the waterway's ecological history as a reference point for its restoration effort. Watch conservation teams coax new life into the Bronx River as they restock it with native fish, lay down oyster beds, and remove invasive species along its shores.
