Stone-Lined and Grass-Lined Waterways

Lining waterways is one way of reducing soil losses through seepage and preventing erosion of the waterway bed. Stone or grass lining is cheap and effective, and does not destroy the animal and plant habitat in the same way as a cement lining. A stone-lined bed for a natural stream has been constructed on the eastern side of the site through the citrus groves to the nursery area. There is another, older, stone-lined waterway taking the overflow from the stream through the wetlands area to the Botanical Garden.
