The most representative ecosystem is the páramo composed of grassland, peat bog, scrubland, swamps and lagoons, and occupying 80% of the Park’s area. It also has super-páramo, a lunar-like landscape, composed of rocks, ashes, and high Andean forests, an important habitat for the Park’s wildlife. The glaciers occupy 4% of the area and they are represented by three volcanoes, Nevado del Ruiz, Nevado de Santa Isabel and Nevado del Tolima, whose melting ice provide water to the streams that make up the rivers originating in the Park; six of these drain into the Magdalena watershed (Gualí, Lagunilla, Recio, Totare, Frió and Coello) and four drain into the Cauca Rivel (Chinchiná, Campoalegre, Otún and Quindío).
