If a tree has a crown radius smaller than what size, only one conductor is required?

In the context of tree support and lightning protection, determining the appropriate number of conductors for lightning protection systems is influenced by the crown radius of the tree. Trees with smaller crown radii typically require fewer conductors because the risk of lightning strikes can be adequately mitigated with a single conductor.

When the crown radius is smaller than 35 feet (10 meters), it indicates that the tree's uppermost branches and foliage, where strikes are likely to occur, do not extend widely enough to necessitate more than one conductor. A single conductor can sufficiently intercept the lightning and channel it safely to the ground. Therefore, for trees with a crown radius under this specified size, utilizing only one conductor simplifies installation and maintenance while still providing effective protection.

In contrast, larger crown radii might increase the surface area that could potentially be struck, thus requiring multiple conductors to ensure comprehensive protection. A good understanding of the relationship between crown size and the lightning protection system can lead to efficient and effective lightning safety strategies in tree management.
