Creating a Framework to Test the Effectiveness of a Suite of Projects in the Maunalua Region

Abstract

The Maunalua region, once renowned for its productivity in agriculture and fishponds, now faces numerous environmental challenges due to urbanization. Degradation of native forests, pollution from impervious surfaces, and declining coral reefs necessitate comprehensive restoration efforts. The Ridge to Reef Project by Mālama Maunalua aims to restore the watershed from mountains to reef, focusing on native reforestation and ungulate fencing. This project worked to collect baseline data and create a framework to help with continuous monitoring. Our framework focused on monitoring water quality and ungulate presence in the mauka region before fencing implementation. Using YSI ProDSS water quality meters and game cameras, we assessed water parameters and ungulate activity in Wailupe, Niu, and Kuliʻouʻou streams and Pia Valley, respectively. Results show varying water quality trends correlated with rainfall and confirmed the presence of pigs within the proposed fencing area. Community engagement, including workshops and outreach campaigns, facilitated stakeholder collaboration and knowledge dissemination. Continuous monitoring is needed following this project to get a better picture of water quality parameters and how well the ungulate fence is working once it is fully constructed. Standard operating procedures for sediment load testing, and ungulate monitoring were created along with a cost estimation table for future use by community groups.
