One of your neighbors has lost a (Japanese) Black Pine to an infestation. If you see small pitch mounds, tiny holes with sawdust in the bark, woodpeckers, or brownish red needles in your pine trees have them checked immediately. They said that when it was quite it sounded like something was chewing on the tree then a month late it was dead. If you do have pine it might not be a bad idea to have them checked by an arborist soon to prevent such attacks. As we get more information we will post it here.
Bill Tall of City Farmer's Nursery will be giving a talk on this topic at our Feb '07 meeting.
