Bank Revegetation

planted-trees-3

We plant riparian trees, such as this Sitka spruce, when needed to reduce sediment delivery to streams.

In most riparian areas in the watershed, bare mineral soils are colonized quite rapidly by shrub and herbaceous plants. Consequently, active restoration of exposed stream banks is usually associated with road improvement, road decommissioning, and bank stabilization projects.

When considering bank revegetation project sites, areas are targeted based on likelihood of sediment delivery from surface erosion and the potential for invasive plants such as knotweed, Himalayan blackberry, or evergreen blackberry to become established.

In areas where riparian vegetation has been severely altered and chronic surface erosion is likely, we plant with native trees and shrubs to accelerate ground cover and limit surface erosion.
