Landcare activities Landcare activities became important in Manly Vale with the creation of the "Return of the Mermaids" Project. The project consists of regularly involving volunteers to collect rubbish, remove weeds and plant local native species in the Mermaid Pool on Manly Creek. The Pool was originally an intact sandy beach with a sparkling waterfall. It became polluted due to illegal dumping and urban development. Invasive and noxious weed started to take over the area. This project was convened under the auspices of the Save Manly Dam Catchment Committee. The SMDCC was established to fight a controversial development in the head waters of Manly Dam by British Motorway constructor Wimpey in conjunction with local firm, Ardel. When bushland was lost to this housing development, the Mermaid Pool Project was initiated to compensate for the destruction. The "Return of the Mermaids" project aims at rehabilitating the Mermaid Pool as much as possible to its pristine state. The project won the People's Choice Award for the 2011 NSW Landcare Awards. It was also a winner
