Background/
Overview: |
Waimanalo streams are considered severely impaired according
to DOH in their TMDL for the watershed. There is mass degradation
of the stream system due to flood control and a high level of nitrates
and phosphates in the streams from intensive agricultural activities. |
Objectives/Goals: |
To reduce the high levels of nitrates in the Waimanalo stream
and reduce the sediment load associated with eroding stream banks. |
Methods Employed: |
Control soil erosion through stream restoration by removing all
existing invasive weeds and replacing with “maintenance free” native
species. Experiment with hydroseeding native plants. Collect soil
erosion data and plant survival data, and conduct water quality
testing. Train and educate youth and volunteers in the restoration
efforts. |
