Coir blankets can cover large areas of streams, river embankments or shorelines, with wetland vegetation grown in it, quickly helping negate erosion in areas with tidal variation, detention basins or wetlands. These blankets are grown in nurseries prior to installation and are therefore conducive for the plants. Sediment collections around roots of plants provide for healthy plant growth. After sometime these blankets get covered with sediment and soil from the wave action and get fully covered with soil. One interesting aspect of this vegetative blanket is that the roots of the plants generally grow very fast, and fix itself to the earth quickly, whereby the relative displacement of the blanket is arrested. These blankets do not float in the medium of water.
