Törzsátmér

Törzsátmér refers to the diameter of a tree trunk. It is a crucial measurement in forestry, arboriculture, and ecological studies. Typically, the diameter is measured at breast height (DBH), which is a standardized height of 1.3 meters (approximately 4.3 feet) above the ground. This standardized measurement allows for consistent comparisons between different trees and across studies.

The measurement is usually taken using a diameter tape, which is specifically designed to account for the curvature of the trunk. Alternatively, a caliper can be used. The unit of measurement is generally centimeters or inches. Variations in törzsátmér can indicate a tree's age, growth rate, health, and exposure to environmental factors such as competition for resources, light availability, and soil conditions.

In forestry, törzsátmér is a key factor in estimating timber volume and predicting forest productivity. Larger diameters generally correlate with greater volume and value of timber. In urban forestry and arboriculture, törzsátmér can be an indicator of a tree's structural integrity and potential risks. Ecological studies often use törzsátmér as a proxy for biomass and to understand forest dynamics and carbon sequestration. Different tree species have characteristic growth patterns, leading to variations in their törzsátmér relative to their age.
