Threats [top]

Major Threat(s): There are currently no threats known to the species. Inga 1 and 2 are existing dams on the Lower Congo with a minimal impact. Inga 3, to be built in five years, will divert a significant amount of flow. Grant Inga will block a great part of the mainstream with major impact. It can also be threatened in the future by mining in the Luozi area. The key component of concrete is found in this region, and there is potential to mining in the area.
