Watershed is the area of land that catches rain and allows it to drain or seep into a marsh, stream, lake, river, and groundwater. Watersheds in Hawaii are characterized by forested areas thus the Hawaiian proverb “Hahai no ka ua i ka ulula’au,” meaning the rain always follows the forest. Studies have shown that deforestation causes a decrease in rainfall in these areas. Protection of our watershed is vital to all life in Hawaii.
