Mount Elgon has different climate zones because of the changes in altitude along the mountain. Each zone supports its own type of vegetation and wildlife.
The first zone is the equatorial climate found in the lowlands below 1,800m above sea level. This area has moderate to high temperatures throughout the year and two rainy seasons. The long rains are from March to May, while the short rains are from September to November. Rainfall is between 1,200mm and 1,500mm each year.
The vegetation here is semi-deciduous tropical forest, though much of it has been changed by human activity. Agriculture is the main economic activity because the volcanic soils are fertile, making this zone densely populated.
The second zone is the montane forest zone, found between 1,800m and 2,500m. It has cooler temperatures and heavy rainfall, sometimes more than 2,000mm a year. The montane rainforests are thick and home to wildlife such as elephants, buffaloes, bushbucks, blue monkeys, and black and white colobus monkeys. Common trees in this zone include giant podocarpus and juniperus.
Above this is the bamboo and moorland zone, between 2,500m and 3,500m. Temperatures drop further, and the weather becomes more unpredictable with cold winds and chilly nights. The bamboo forest is home to unique species like golden cats, while elephants move higher in search of salt licks. Beyond the bamboo lies the moorland, covered with plants that survive in harsh conditions of strong sun and wind.
The last zone is the high alpine zone above 3,500m. Here, the climate is extreme and changes quickly. Daytime temperatures may feel pleasant, but nights can drop close to freezing. The landscape is rocky with few specialized plants such as giant lobelias and groundsels.
The different climate zones of Mount Elgon shape the vegetation, wildlife, and life around the mountain.
