I’ve always known that hollows in trees are the natural home for bees, but this was reinforced when several trees were cut down over the road.
The camphor laurels were lifting the foundations of the church, and weren’t in a great state anyway. So they had to go.
The pieces of trunk left behind demonstrate clearly how big a hollow can be within a tree. No wonder I keep finding wild hives in camphor laurel trees, including two in nearby Petersham Park.
