A high-value tree that might have a lightning protection system is commonly characterized by its historic significance. Trees with historical importance often possess unique traits, such as age, rarity, or cultural attachment, which contribute to their value. This value can justify the investment in a lightning protection system to preserve the tree, as the loss of such a specimen would have not only ecological impacts but also cultural and historical repercussions.

While large leaves, a fast growth rate, and fruit-bearing capabilities may contribute to a tree's ecological or economic value, they do not inherently signify the need for a lightning protection system as strongly as historic significance. Trees with historical backgrounds are frequently located in public spaces or on private property where their loss would be notably felt, making their preservation a priority. Such trees are often part of the identity of a place, further emphasizing the importance of protecting them from environmental threats like lightning damage.
