Of all the landscapes supported by PAPFor, the Nimba Mountains landscape is the one most impacted by industrial mining. The Liberian part of the Nimba Mountains was exploited from the 1960s to 1980s. Much of the upper section of the massif was disfigured. This site is no longer exploited but other important forest areas are. On the Guinean side, a mining perimeter in the process of being exploited is at the heart of the massif and is on the immediate border of the Monts Nimba Integrated Reserve, which could threaten the Outstanding Universal Value of the World Heritage Site. Close collaboration with the miners is necessary to minimise the direct impacts (deforestation, diversion of watercourses, pollution) and indirect impacts (workers, increased hunting pressure) of mining.
