University of Utah researcher Elizaveta Litvak used low-cost tree sensors for her groundbreaking study on water use in urban landscapes.

An intense look at urban landscapes in Los Angeles concluded that some 70 billion gallons of water a year is being lost to evaporation, largely because of over watering of lawns.

Tallahassee-based researcher and co-author Elizaveta Litvak says a decade of field research involving individual tree sensors and satellite data turned up countless surprises. 

“The most mind-blowing part was when we discovered that grass was using much more water than trees. Because first my studies were completely focused on trees.”

The study was backed by a grant from the National Science Foundation. Litvak works remotely for the University of Utah.
