Eia kekahi, pili pono i ka wahi hoʻopihapiha ʻoihana kahi kahawai melaleuca ʻōiwi e kākoʻo ana i ka laulā o nā flora pale a me nā holoholona.

Me ia mea, ua hoʻomākaukau ka Hale Hoʻohālikelike i kahi papahana hoʻomalu piha honua piha no ka ʻae ʻana o ke Keʻena ʻĀina. Hāʻawi kēia hoʻolālā i kahi wahi i hoʻopihapiha ʻia me kahi pūnaewele o nā pahu weir e hoʻopaʻa ai i ka maikaʻi o ka tailwater.
