What's Killing California's Trees

The ongoing drought in California has been tough on trees.  Or has it?

While it's apparently true that 12 million trees have died in recent years in California, the deaths are probably caused by a combination of drought and insects. 

Naomi Tague at UC-Santa Barbara's Ecohydrolab is one of the authors of a study that assessed the various causes of various tree deaths. 

It clears up the relationship between bugs and droughts, and provides possible future patterns for tree deaths in certain climate conditions. 

Dr. Tague visits the Exchange with highlights.
