## The Land in the Early 1960s

This area of Papago Park contained cacti and other desert plants, along with a wash.

## The Land Gradually Changes

In 1967, the City of Tempe constructed a water treatment plant to provide water for its growing population. Over the next 30 years, the plant intermittently discharged backwash filter water into the wash. This resulted in a dense growth of trees, shrubs, and other plants.

## The Land Today

Modern methods of water conservation have reduced the amount of water discharged into the wash. So, the community has worked together to preserve the lush riparian habitat. They call it the "Green Line."

A riparian habitat is a strip of lush vegetation found along streams, rivers, and washes.
