The most broadly described zone is the grass páramo. Grass páramos cover large areas of mountain ranges, while others are limited to small areas on slopes and summits of very high mountains. The term "páramo" is sometimes used to refer to this specific type. It has continuous vegetation and plant cover with a "yellowish to olive–brown" look due to the combination of dead and living grasses. The grass páramo extends from approximately , and is composed of mostly tussock-grasses and bunch-grasses. "Calamagrostis intermedia" and other grasses of the genera "Calamagrostis" and "Festuca" tend to dominate this zone. Other common vegetation includes large and small shrubs, stunted trees, cushion plants, herbs, and rosette plants. While these are the dominant species, grass páramos can also contain tall- and short-grass communities, including herbaceous and woody vegetation. Due to its easier access and high levels of grass, this zone is more impacted by humans and suffers from both burning and grazing activities.
