A riparian zone is the land bordering a stream, river, lake or other type of surface water. These
important ecosystems are typically dominated by diverse water-loving plants. Riparian zones act as a buffer separating human activity from sensitive aquatic ecosystems. The protection of the riparian zones in urban areas is of utmost importance in part because the land separating the streams from recreational and urban development areas is shrinking. This increased development causes stream bank erosion, increases the potential to introduce non-native species and increases sun exposure which warms the water thereby reducing oxygen levels. Planting native trees and shrubs is a restoration tool used to combat these issues. Stream plantings reduce erosion by stabilizing the soils on stream banks, increases resiliency preventing invasive species from establishing, provides shade which keeps streams cool as well as food and habitat.
