dying maple and alder trees
Hi I have five acres in rural Clackamas county near Boring on the west slope of Tower Hill. Over the last ten years or so, especially this last five, we are seeing our big leaf maples slowly dying. These are big trees probably over 40+ years old. The most recent one is really going quickly. Our alders are also seeing leaf loss. I have heard that several years of drought may be the cause. Is that true? Is there any way to curtail or reverse the seeming inevitability? I need suggestions. Please advise. Thank you.
