Background/
Overview:
Coastal and marine ecosystems along the entire south coast of Molokai have been degraded by sediment-laden runoff that has damaged beaches, reefs, and marine life.
Objectives/Goals: To reduce water quality impairments of Molokai’s South Shore and Kualapuu Aquifer by limiting soil movement and attached chemicals through revegetation and educational efforts.
Methods Employed: Installed temporary rain gauges, installed three weather monitoring stations, and analyzed water samples taken at stream outlet. Planted 3000 stargrass cuttings, took inventory of plants, assessed coastal areas designated for revegetation, scheduled planting of trees, grasses, and shrubs, completed Hawaiian curriculum on soil and water conservation. The educational measures of this project were adopted so fully by the community that community leaders organized island wide meetings to initiate and apply for the USDA Empowerment Zone grant with the major focus to be Molokai’s Environment and Water Quality. Furthermore, with vegetation being planted within a ½ acre plot, the project found that soil loss from that area was reduced by half.
Pollutants of Concern: Sediment, turbidity
Watershed: Manawainui Watershed, island of Molokai
Size of Project: • Not described in report
