What type of vegetation is preferred for bank stabilization when possible?

For bank stabilization, trees and shrubs are preferred because of their ability to establish extensive root systems that anchor soil and reduce erosion. The dense root networks of trees and shrubs help absorb water and stabilize the bank by holding the soil in place. Additionally, these plants provide shade and habitat, contributing to the overall health of the ecosystem.

Trees and shrubs are particularly effective in areas where bank erosion is a significant concern, as their growth can occur vertically and horizontally, providing structural integrity to the bank. Furthermore, the choice of these vegetation types can lead to improved water quality and habitat diversity, as they create a more balanced ecosystem along water bodies.

In contrast, non-native species may not provide the same level of soil stabilization and can sometimes disrupt local ecosystems. Native grasses, while useful, generally do not offer the structural support that trees and shrubs provide for bank stabilization. Relying on any available plant material lacks specificity and can result in the selection of inappropriate or ineffective species that do not contribute to long-term stabilization efforts.
