The rift escarpments and volcanic highlands create diverse altitudinal gradients and microclimates, producing varied vegetation zones. Moist, windward slopes are often dominated by montane forests rich in endemic plant and animal species. These forests provide critical habitat for wildlife and act as important catchment areas for water resources.
