In the border zone, which statement is true regarding the establishment of trees and shrubs?

In the border zone, the promotion of species over 25 feet is considered a strategic approach to create a layered landscape that accommodates height diversity and maximizes benefits such as windbreaks and wildlife habitat. Tall trees can also help shade the area, which can be beneficial for the surrounding environment and support the establishment of other plants by modulating sunlight.

Establishing species over 25 feet can also promote healthier ecosystems and ensure the border zone serves its various functions effectively, such as reducing soil erosion and improving aesthetics. Choosing taller species supports the overall goals of creating a diverse and dynamic planting area that can adapt to different environmental conditions and wildlife needs.

In contrast, the other options either limit the potential for diversity or do not align with the objectives of creating a resilient and functional landscape.
