The Need for Active Restoration

Riparian restoration transforms weedy, abandoned land into valuable native riparian savanna, woodland, and forest. The success of these projects depends greatly on science and technology to ensure that the projects benefit targeted wildlife, the environment, and local communities.

Without active restoration, invasive weeds such as arundo and tamarisk invade denuded areas and diminish the re-growth of native vegetation. The impact of invasive weeds is devastating. They provide no food or shelter for wildlife. They increase erosion to river channels and banks and therefore damage bridges and roads. Also they reduce the availability of ground water and drastically change river flow and velocity which further impacts native habitat, wildlife and human safety. River Partners manages a restoration project for at least three years. During this time, we ensure native plants grow into established communities. By experimenting with native grass and understory plantings, we have made great advancements in producing quality habitat and eliminating the invasion of weeds.

Below is a list of plants that River Partners routinely plants in our riparian restoration projects.
