What practice improves air circulation in tree canopies?

Crown thinning is a forestry practice that involves selectively removing branches from the upper portion of a tree's crown. This practice is designed to reduce the density of foliage, allowing for better light penetration and increased air circulation within the canopy. Improved air circulation is essential for several reasons: it helps reduce the likelihood of fungal diseases that thrive in moist, stagnant air, and allows for better photosynthesis as more sunlight reaches lower leaves.

In addition to enhancing air movement, crown thinning can also promote the growth of remaining branches by reducing competition for resources such as light and nutrients. This practice not only benefits individual trees but can also enhance the overall health and resilience of the forest ecosystem. By optimizing the structure of the tree canopy, crown thinning contributes to a more vigorous and sustainable forest environment.
