Final answer:
Shelterwood harvesting is a forestry management technique that maintains a canopy of mature trees to protect and encourage the growth of shade-tolerant, slow-growing understory seedlings.
Step-by-step explanation:
The method of tree harvesting that favors slow-growing trees which are shade-tolerant is known as shelterwood harvesting. This approach to forestry management is designed to maintain a partial canopy of older trees that provide shelter for developing seedlings of the same or different species.
Shelterwood harvesting is conducted in a series of cuts, gradually reducing the canopy to encourage the regeneration of desired understory species, which are typically shade-tolerant and would not thrive in full exposure to the sun. These methods contrast sharply with clear-cutting, which removes all trees in an area, often leading to a barren landscape for an extended period. By preserving a canopy, shelterwoodcutting promotes a more stable environment for young trees and helps to maintain biodiversity, soil stability, and aesthetics of the landscape.
