Common plant types in the humid mountain valleys include Uapaca togoensis, Cola lateritia maclaudii, Parinari excelsa, Piptadeniastrum africanum and Canarium schweinfurthii.

Higher altitudes of the Loma and the Tingi are covered with a savanna of Syzygium, Kotschya ochreata, Monechma depauperatum, and the tree ferns, Cyathea subg.

Finally the high gallery forest is dominated by Parinari excelsa with the tree fern, Cyathea camerooniana, and the bamboo, Oxytenanthera abyssinica.

[8] The landscape has been badly affected by mining on Mount Nimba and general clearance for farming as well as more recent civil war in Sierra Leone and Liberia.

Despite its park status iron ore mining on Mount Nimba was still ongoing up until the Liberian Civil War, while the Loma Mountains are perhaps the best preserved part of the region.
