* High Andes (Puna): This is the highest zone, characterized by cold, dry conditions and high altitudes. The vegetation here is sparse, consisting of alpine grasses and shrubs. The Incas adapted to this harsh environment by developing techniques for herding llamas and alpacas, which thrived on the limited resources.
* Cloud Forest (Ceja de la Selva): Situated below the Puna, this zone is known for its high humidity and frequent cloud cover. It experiences a mild climate with moderate temperatures. This zone supported a rich variety of flora and fauna, including trees like the Polylepis and a variety of orchids. The Incas utilized this zone for agriculture, planting crops like potatoes and quinoa.
* Highland Valley (Quechua): Located between the cloud forest and the lower valleys, this zone is characterized by fertile soils and a more moderate climate. The Incas cultivated a variety of crops here, including corn, beans, and squash. They also built their most important cities and temples in this zone.
* Lower Valleys (Yunga): Situated on the eastern slopes of the Andes, these valleys are characterized by a warm, humid climate and abundant rainfall. The Incas cultivated various crops here, including cotton and coca.
* Coast (Costa): This zone is located along the Pacific coast and experiences a dry desert climate with little rainfall. The Incas developed irrigation systems to support agriculture in this region, cultivating crops like beans and chili peppers.
It's important to remember that these zones are not rigid boundaries but rather gradients of climate and vegetation. The Incas adapted their way of life to the specific conditions of each zone, utilizing their unique resources and challenges. Their impressive engineering skills and agricultural practices allowed them to thrive in this diverse landscape.
