I live in a wooded neighborhood in south Ames (Timberland Road). Is something killing the large oak trees this summer? On my street, I have noticed one large old oak tree with no leaves plus two other large oaks with many bare branches at the top of the trees. On the neighboring Woodview Drive, I see another large old oak tree with no leaves and another one recently cut down that had many dead branches. Our neighborhood has many large old oak trees. I have two in my yard that appear to be alright. I am wondering if the oak trees are getting a disease or if they are just getting to the end of their life span. I have lived here for 15 years and this is the first time seeing large old oak trees die around here. Thank you. Harvey Terpstra
