Lake Tiriara

Conservation benefit: Protection of Lake Tiriara

Community benefit: Boardwalk and public restrooms

The Cook Islands consist of 15 islands scattered over 1.2 million square miles in the center of the Polynesian triangle of the South Pacific. Mangaia is the second largest island in the Cooks, and at an estimated age of 18 million years, it is thought to be one of the oldest islands in the Pacific.

Lake Tiriara is located in the southern part of the island and opens into a cave in the makatea (raised terrace of coral limestone). The biological diversity of this lake and its surrounding environment is at risk due to poor agricultural practices and overall lack of proper management of the island’s environment. In return for Seacology providing funds for a boardwalk around the lake, a public restroom, and some signage, the village has promised to protect the lake by barring pesticides, dumping, tethering of livestock, and construction of any building within 50 meters of the shoreline.
