Drought and Trees

Here's an interesting post about the effects of drought on trees.
In the short term, trees are drought-resistant. The longer a plant lives, the less vulnerable it is to one or a few bad years. But over the long term, rainfall determines what kinds of trees -- if any -- can live in an area. As the rainfall drops, the more water-hungry species disappear. Eventually the trees peter out entirely into prairie or even desert scrub.
