Oaken Lad

Thanks for your comments. The tree branches were reduced in length about 15 years ago. I’m fairly sure there’s no short-term threat but, living and parking under a large tree as we do, I’m interested in how we can minimise any future risks. Here’s a photo of the hole, with a few acorns to show that the hole isn’t a large one - but big enough to rear three squirrels in it.

Hi, I live in Wales and we have a large, old oak near our house. I noticed today that squirrels have made/enlarged a hole in the flattish middle of the tree, where the main branches grow out and water can collect, and 3 young squirrels emerged from the hole. I don’t much like squirrels but my concern is that water hasn’t/doesn’t slowly rot the tree from the inside to enlarge the hole made by the squirrels. I’m considering putting sand into the hole and then a large stone on top, in the hope this would reduce the water damage and slow any internal rotting. Is this a good idea, could sand damage the tree? The oak’s about 400 years old and I want it to outlive me… Any comments gratefully received.
