In the Midwest USA I just had an arborist come look at my trees yesterday. My three spruce trees are beyond saving due to a fungus. My ash and my two birch trees all need immediate treatment to save them from various borers and invasive beetles. That's over half the trees on my plot that are in trouble. As we replant forests to be carbon sinks, we really need to make sure they are diverse with tons of species so we don't have mass die offs from one problem.
