Assessment Information [top]

Red List Category & Criteria:	Least Concern ver 3.1
Year Published:	2010
Assessor/s:	Graf, D.L.
Reviewer/s:	Van Damme, D., Seddon, M.B. (Mollusc Red List Authority) & Pollock, C.M. (IUCN Red List Unit)
Contributor/s:
Justification: Grandidieria burtoni is widespread and common in Lake Tanganyika. Although there are some generalized threats to the lake and the Lake Tanganyika ecoregion is considered “vulnerable” (Thieme et al. 2005), the species is regarded as Least Concern.

Geographic Range [top]

Range Description:	Grandidieria burtoni is endemic to Lake Tanganyika. This species is described as common. Lake Tanganyika Biodiversity Project distributional data shows present at 16 sites around the lake.
Countries:	Native: Congo, The Democratic Republic of the; Kenya; Tanzania, United Republic of; Uganda; Zambia

Population [top]

Population:	This species is common and abundant.
Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	Grandidieria burtoni has been shown to be a direct-developer, lacking the parasitic larval stage typical of other freshwater mussels (Kondo 1990). The species is common in the littoral zone around Lake Tanganyika.
Systems:	Freshwater

Threats [top]

Major Threat(s):	No specific threats are documented for Grandidieria burtoni, but Lake Tanganyika is known to suffer from sedimentation due to surrounding deforestation, water pollution near urban areas and over-fishing. These effects are all worse at the northern end (Thieme et al. 2005). Although host specificity is not known, any impacts on the fish community e.g. overfishing and stocking, may affect the species. As global warming effects the stratification of the lake, it may affect the status of this species in the future.
