"The moment the tree loses a branch or major limb is usually when the arborist keeps a closer eye on it. If exposed to the elements, the root of the branch can be a breeding ground for tree-eating bacteria, which can make their way deep into the heart. Trees knocked down by high winds or storms are often considered a lost cause unless replanted under the right conditions. Once the tree is marked for removal, everything must go, even the stump. A Cairns stump grinding expert typically uses machine with circular saws that grind the stump into shavings. That way, the space can be used for more productive purposes, perhaps even plant a new sapling in its place."
