What is the most commonly used measure for purchasing trees today?

The most commonly used measure for purchasing trees is diameter, specifically the diameter at breast height (DBH). This measurement is critical for several reasons. Firstly, it provides a standardized way to gauge the size and age of a tree, which are important factors in assessing its value. Diameter typically correlates with the tree’s overall health and growth potential, making it a reliable indicator for buyers and sellers in the timber and horticulture markets.

Diameter measurements are also practical because they can be taken quickly and with minimal impact on the tree itself, ensuring that the assessment process does not damage the very product being evaluated. In contrast, measurements like height or crown volume can be more variable and may depend on specific tree species or environmental conditions. Additionally, weight is often not used due to the logistical difficulties and variations in moisture content that can affect a tree’s weight at the time of measurement. Therefore, using diameter as the standard measure helps streamline the purchasing process and provides a consistent framework for evaluating tree stock.
