The lower region of the Rwenzori Mountains comprises the tropical montane zone, which extends from around 1800 meters to 2500 meters above sea level. The region is distinguished by a lush forest that attracts substantial rainfall year-round. The elevated moisture levels in this atmosphere foster a rich and diversified habitat, hosting the majority of plant and animal species in this region of the highlands.
Characteristic of the tropical montane forest zone
The Tropical Montane Forest is characterized by towering trees with dense canopies that obstruct sunlight from penetrating the forest floor. The atmosphere is predominantly shrouded in clouds and mist, rendering it enchanting and intriguingly lovely. The area is characterized by a diverse array of tree species, including mahogany, fig, and numerous ferns. The tropical montane forest zone is characterized by epiphytes, including orchids and mosses, which thrive on tree trunks owing to the elevated moisture levels at this altitude. The forest features a diverse array of shrubs, herbs, and tall grasses, imparting the montane zone with a distinctive and appealing appearance that attracts hikers from near and far to explore its beauty.
The tropical montane forest zone contains a diverse array of fauna, including numerous species peculiar to the Rwenzori Mountains. Among the many primates that have found the mountains to be a very convenient place to stay for decades are colobus, blue, and hoest monkeys. The mountains also contain the three-horned chameleon, which is endemic to this area, and the Rwenzori turaco bird. The forest also has tiny mammals, various reptiles, and numerous insects.
Bamboo zone (2,500 meters to 3,000 meters)
As the altitude of the Rwenzori Mountains changes, so does the vegetation cover, which is one of the main factors contributing to climate change. The bamboo zone, situated above the tropical montane forest zone, extends from 2500 meters to 3000 meters above sea level. The area is renowned for its bamboo trees interspersed with various kinds of vegetation.
Characteristics observed in the bamboo zone
The bamboo zone is characterized by a diverse array of plant species, including bamboo trees that can reach heights of up to 20 meters. Mimplosis plants are prevalent here, showcasing their beauty with purple blossoms. The Oldman’s beard is another species that is often observed in the bamboo zone area. In addition to birds like the Rwenzori double-colored sunbird and the mountain buzzard, a few mammals live here, some of which migrate specifically to eat on the bamboo stems, such as L’hoests monkeys.
Afro-Alpine zone / Moorland zone (3800m to 4500m)
The Alpine zone begins at an elevation of 3800 meters and ends at 4500 meters. It is one of the distinctive areas in the Rwenzori Mountains, characterized by expansive vistas and vast marshlands. In addition to having exceptionally low temperatures—which can occasionally reach freezing—the Alpine zone is well known for generating snowfall.
