What term is used to describe a construction operation that consists of cleaning a designated area of trees, timber, brush, and rubbish?

The term "clearing" specifically refers to the operation of removing trees, timber, brush, and other debris from a designated area to prepare the site for further construction activities. This process is essential in ensuring the land is suitable for building foundations, roads, or other infrastructure by eliminating obstacles that could interfere with construction.

While grading involves leveling and smoothing the land surface and excavation focuses on digging trenches or holes for foundations, clearing is distinct because it primarily addresses the removal of organic and inorganic materials from the surface. Site preparation encompasses a broader range of activities, including both clearing and grading, but the most precise term for the specific action of removing unwanted vegetation and debris is "clearing." Thus, this term is the most appropriate choice for describing the operation in question.
