Final answer:
Selective logging is a tree-harvesting method that removes most trees but leaves the canopy intact. It helps minimize the negative impact on the forest and allows for natural regeneration of the trees.
Step-by-step explanation:
The tree-harvesting method that uses three basic cuttings, the first of which removes most trees but leaves the canopy, is called selective logging. In this method, only certain trees are harvested, while others are left standing to maintain the forest canopy and preserve the ecosystem. Selective logging helps to minimize the negative impact on the forest and allows for natural regeneration of the trees.
