The Guinean montane forests are a tropical moist broadleaf forest ecoregion of West Africa.[2][3][4]

The ecoregion occupies the portions of the

Tingi Hills in Sierra Leone, the Nimba Range in Guinea, Liberia, and Côte d'Ivoire, and the Monts du Toura in Côte d'Ivoire. Mount Bintumani in the Loma Mountains is the highest peak in West Africa west of Mount Cameroon. The next highest peaks in the region are in the Sankan Biriwa
massif (1850 meters) in the Tingi Hills.

Average rainfall is between 1,600 and 2400 mm per year and many important rivers have their sources in these mountains.[5]

Flora

These mountains have a distinct plant cover in various phases according to elevation, with up to 35 endemic species including a

Cyathea camerooniana, and the bamboo, Oxytenanthera
abyssinica.

Bromeliad native outside the Americas, is endemic to the Fouta Jallon.[6]

Fauna

Leopards (Panthera pardus) are the largest predator in the ecoregion. The ecoregion supports populations of the endangered western chimpanzee (Pan troglodytes verus).

Near-endemic birds include Sierra Leone prinia (

Coccycolius iris
).

Endemic amphibians include the western Nimba toad (

viviparous. The Guinea screeching frog (Arthroleptis crusculum) is a threatened species found in the Nimba Range, Mounts Béro, Tétini, and Foko, the Simandou Range (Mts. Tibe and Fon), Loma Mountains, and Tingi Hills in high-altitude grasslands and in gallery forests during the dry season.[7] Ptychadena submascareniensis is another frog species that has been found only on Mt. Nimba and in the Loma Mountains.[8]

Threats and preservation

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.
