While most palms are inhabitants of tropical forests and typically range from lowlands to mountain and cloud forests up to 1,800 meters, certain species have adapted to thrive at significantly higher elevations in the Andes.

Rarely, specific palms such as the wax palm and some species of the genus Geonoma are able to grow at elevations as high as 3,000 meters (approximately 9,800 feet) in the Andes.1

The ability of plants to inhabit the Andes is determined by a complex interplay of climatic variables, including temperature, wind, radiation, and moisture availability, which are amplified by altitude. In the Andean region, tropical palms and areas of eternal snow can exist within a few miles of each other due to the dramatic variations in elevation, which range from deep, warm gorges at 1,600 feet to peaks exceeding 20,000 feet. These specialized palms have evolved to survive within these specific altitudinal bands, demonstrating the family's broad capacity to adapt to diverse habitats beyond their traditional tropical lowland environments.21
