Which of the following instruments can be used to measure tree height?

• A. Compass
• B. Clinometer
• C. Diameter tape
• D. Increment borer

Answer: (B)

The clinometer is the correct instrument for measuring tree height because it is specifically designed to measure angles of elevation or depression. By determining the angle from a specific distance away from the tree and applying some simple trigonometry, you can calculate the height of the tree. This use of angular measurement is essential in forestry when assessing the vertical growth of trees and analyzing forest structure. Other instruments mentioned serve different purposes; for example, a compass is primarily used for determining direction and navigation, not height. A diameter tape is utilized for measuring the circumference or diameter of a tree, providing information about its thickness rather than height. An increment borer is a tool used to extract a core sample from a tree, allowing for measurement of growth rings over time but not for determining tree height. Thus, the clinometer's design and function make it the most suitable tool for this task.
