The purpose of an Increment Borer is to take core samples from trees. This specialized tool allows researchers and foresters to remove a thin column of wood from a tree trunk without causing significant damage. By extracting a core sample, one can analyze tree growth rings, which provide valuable data regarding the age of the tree, historical growth patterns, and environmental conditions that may have influenced its growth. The ability to assess growth rates and age is crucial for understanding forest dynamics and managing forest resources effectively. This method is non-invasive compared to cutting down a tree, making it an ideal choice for studying tree health and wood quality over time.

The other options, while related to forestry and environmental science, do not specifically describe the function of an Increment Borer. For instance, measuring tree diameter typically involves using tools like calipers, and collecting soil samples is done with specific soil sampling tools rather than an increment borer. Assessing tree health involves a broader range of observations, including visible signs of disease, pest infestations, and overall vigor, which cannot be determined solely through core sampling.
