Lightning protection

The Morton Arboretum is using an advanced lightning protection system for many trees in our collections. The system can equip a tree so that lightning will be conducted harmlessly into the soil.

"The new system uses specially designed fasteners, called Arborbolts, that further protect the tree by reducing the size and number of wounds that must be made," says Kris Bachtell, Arboretum Vice-President of Collections and Facilities.

A fuse allows us to measure strike frequency and confirm the effectiveness of the system.
