Government agencies' lack of capacity to enforce environmental legislation increases the threat. Land tenure conflicts and ecologically destructive subsistence farming practices ( slash and burn agriculture), exacerbated by poverty, also pose problems for the environment. The range has two classified forests: Pic de Fon, designated in 1953, with an area of 256 km², and Pic de Tibé, designated in 1945, with an area of 60.75 km².

Mining

Simandou has the potential to become the site of the largest integrated iron-ore mine and infrastructure project ever developed in Africa, consisting of a large new source of iron ore and creating a 650 km new railway to the Guinean coast at Matakong. However, the potentially lucrative blocks I and II were mired for several years later in litigation of possible corruption. This corruption, which occurred through the use of bribery involved two Western foreign companies - Rio Tinto, a British-Australian company and BSGR. Around 2015, the mining project seemed to have been sidelined due to dwindling global iron demand. However, a version of the full original mining project was re-instated in late 2019 and confirmed in 2020 with the signing of a new agreementSMB-Winning consortium deal

Namesake

There is a town of the same name in nearby Côte d’Ivoire (Ivory Coast). This town is not to be confused with Siamandou further to the west.
