Tiny Parasite Threatens California Native Plants

It's not a great time to be a tree or a plant in California. There's the drought of course, which has us starving our gardens, lawns and golf courses. And don't forget Sudden Oak Death: it began devastating oak forests more than 20 years ago, and it's still around. And now there's a new threat facing California's native plants: a deadly parasite, showing up in plant nurseries and the wild. Experts are spending hundreds of thousands of dollars in a race to keep it from spreading.
