Briefly, the scientists working the Oregon coast found that sand could be controlled only by the use of one type of grass and by a system of follow-up plantings with other growth. The grass sets up a beachhead by holding down the sand in an intricate lacing of roots. This permits certain other plants to gain a foothold. The beach grass is extremely difficult to grow in nurseries, and part of the solution to the dune problem involved working out a system for propagating and handling the grass. (en) |
