Shoreline Management and Landscaping: Educational Resources for Landowners

The way we develop shoreline property, build our homes and businesses, landscape and garden can profoundly affect the environment which sustains our quality of life. Learn how to preserve native plant communities and use native species in landscaping which can help to reduce erosion and maintain slope stability. You will also help improve water quality, salmon habitat, the beauty of the region, and reduce landscaping and maintenance costs.

The plants listed below are provided only as a starting point and introduction to the landscaping value of native plants. Each plant has specific needs as to soil type, sun exposure, and soil moisture. The references provided here will help you develop a planting plan of species best suited to your particular situation and site conditions. Native plant landscaping can be specifically beneficial for shoreline property owners who are concerned about erosion and landslides. Increasing shoreline buffer widths and reducing the extent of lawns are two simple and effective steps that shoreline owners can take to help keep the Puget Sound area green.

*Note: It should be clearly understood that the use and success of plants to reduce erosion and slope problems is dependent on site specific conditions such as slope, aspect, geology, light and water availability, and soils. Planting on slopes requires a clear understanding of the processes affecting slopes, techniques to be employed to ensure success, and the potential hazards of working on steep slopes in vulnerable areas. Permits may be required before slope restoration planting begins. Check with the appropriate local city or county agency.
