LAIST.COM - On a recent triple digit summer day, I made my way out to a dusty field at UC Riverside, the research center of California’s citrus universe.
Row after row of tangerines, oranges and pomelos —11,000 in total — baked under a heat dome. Off in the distance, wildfire smoke passed in front of the San Bernardino Mountains, which had been covered in thick snow just a few months ago.
The dusty field is just one of the many plots that the university uses to trial new trees, grow budwood for distribution and come up with solutions for devastating problems like Huanglongbing, a bacteria driven greening disease that’s threatening trees world wide.
However, I was there to check out a block of 48 trees sitting along a fence that look nothing like the thousands of citrus around them. Inconsequential at first glance, you could easily imagine them along any road in Los Angeles, but that’s kind of the point. The trees are being tested to see if they can survive our hellishly hot and dry future driven by climate change.
Where, how and why these trees are being tested
It’s a collection of 12 different species — four of each — pulled from around the world and being run through the gauntlet by the U.S. Department of Agriculture. Planted seven years ago, they were given supplemental water to help them get established, but since then they’ve had to survive on their own through record-setting heatwaves and drought years.
