The number of storms in recent years increases the need for better tree and landscape decisions for property owners. Research regarding landscape damages for different storm intensities, what plants get knocked down by winds more often, and priorities for landscape restoration have been intensified by many southern state universities' forestry and horticultural departments.
Trees and landscapes have been valued since humans were given gardens for food and enjoyment. Once people determined how to harvest seeds, how to plant gardens and landscapes, and how to relocate trees and plants, then decisions about what to use and what not to use began to set values for plants. It is this author's opinion that these practices logically date back to the beginning of history.
The value of a tree can only be determined if we agree. Any value given, whether by a layperson or a professional, is real when another person involved in the process agrees to that value. The value used in the final decision can also be a different value from the one determined by the experts who worked on it (especially when the experts worked on different sides of a valuation case).
