5 Banks were raked and seeded. The coconut coir matting was pulled up over the seeded bank and staked into place. The coconut-fiber material provides a temporary stabilizing mechanism while plants become established. The matting will degrade in 3 to 5 years, and the plant roots will take over the job of stabilizing the bank. These are the only systems I know in which this is the case.
Time is on our side, so to say. . . .
