What is a chainsaw used for in forestry work?

A chainsaw is a powerful tool primarily utilized for cutting trees and branches in forestry work. It is designed to handle various tasks such as felling trees, limbing, and bucking logs, making it essential for managing forest resources and carrying out land-clearing operations. The efficiency and precision of chainsaws enable forestry workers to complete tasks quickly and safely, which is crucial in environments where time and productivity are vital.

The other options do not align with the primary functions of a chainsaw. For example, planting saplings is typically done using hand tools or machinery designed for planting, and measuring tree heights is usually accomplished with specialized tools like clinometers or rangefinders. Spraying pesticides is a task usually performed with sprayers or applicators designed for that purpose, highlighting that while each option relates to forestry work, the chainsaw's specific function is distinctly focused on cutting-related tasks.
