How heat damages Arizona Saguaros

More from this show

Record heat has been dangerous not only for people but for desert plants as well, including Saguaro cacti. Many Saguaros are suffering dehydration and heat-related stress.

At the Desert Botanical Garden, three of more than 1,000 saguaro cactuses have toppled over or lost an arm recently, a rate that officials there say is highly unusual.

Today we talked to Kevin Hultine, Director of Research in the Department of Research, Conservation and Collections at the Desert Botanical Garden.
