PONC MAINTENANCE FUND <br />Year End FINAL Report # C.008221 <br /> <br />DAWRF COCONUTS ALONG SHORELINE FOR COASTAL EROSION MITIGATION <br /> <br />driven <br />rising Sea Levels. This causes sand along the shoreline to shift, as well as flooding in low lying <br />areas. Hawaii experienced several coastal flooding events in 2020, mostly during large swells <br />mixed with king tides. In West Hawaii, anchialine ponds are increasing in size, and some new <br />ones are emerging with the rising sea level. <br /> <br />-road vehicle <br />eline. To <br />help mitigate these erosion issues, Kohanaiki Ohana has been planting native trees like Naio, <br />and Dwarf coconuts along shoreline. Additional native ground covers are planted around <br />trees to help stabilize sand between them. <br /> <br />Dwarf coconuts where hand selected by Mason Myrmo and sprouted in our nursery to get <br />established. Trees have now become a few feet tall and are being planted along the mauka <br />portion of the coastal beach crest. Out planted trees are spaced every 25-30 feet. Our team <br />waters them regularly to get them and native ground covers established, and continues to <br />weed invasive species out of the established areas. <br /> <br /> <br />MONITOR MAIAPILO, PRUNE BACK BRANCHES AND REMOVE INVASIVES <br /> <br />Maiapilo, both the established individuals as well as the recently planted individuals which <br />were propagated at our nursery, are thriving along the O'oma coastline. Some areas remain <br />too thick of heliotrope and keawe to monitor. <br /> <br />Additional small maiapilo plants are regularly discovered as the invasive plants are removed. <br />Great care is taken when pruning the understory to identify additional plants. Invasive <br />species are carefully pruned off of maiapilo. Heliotrope trees seem to harbor most young <br />maiapilo found at the beach park in their understory. Soil building leaves, shade, water <br />habitat for young maiapilo. Any maiapilo already in the sun have invasive species removed <br />around them within a distance of 2-3 feet. Small berms and stacked rocks have been placed <br />around maiapilo plants that are exposed to vehicle traffic for protection. <br /> <br />Directly out planted seeds are placed around maintained areas outside of off-road track, to <br />be able to monitor them when they sprout. Seeds brought to nursery are cleaned and then <br />soaked before putting into sprouting trays to be later out planted on-site. <br /> <br /> <br /> 3 <br /> <br />
