I have been watching the trees and plants dieing for lack of water. When walking on the grass it sounds like you might be walking on corn flakes. I have learned to read the signs of plant stress pretty well. Watching oak trees, of witch we are loosing many. Oaks have no tap root so they will stress faster than say a pine.
Back to what I have learned. The first sign is that the leaves will wilt down to conserve water evaporation. Next they will Begin to droop and curl. Then turn yellow then brown. This tree is now a heap of trouble if not dead. I have taken a couple of photos, just to finish my story.
