Threats [top]
Major Threat(s):
The shorelines of the Wissel Lakes are surrounded by one of the densest concentrations of agricultural land within the New Guinea highlands. There has been extensive land clearance for sweet potato plantations, timber, and livestock ranching. Changes in land use are known to be impacting the water quality in the lakes, through sedimentation and eutrophication (C.M. Austin pers. comm. 2008). The local villagers harvest this species for food. While the precise effects of these impacts are not yet well understood, they are believed to be having a significant impact on habitat quality and population size (C. M. Austin pers. comm. 2008).
Conservation Actions [top]
Conservation Actions:
There are no species-specific conservation measures in place for this species. Lake Paniai is included within the Enarotali Nature Reserve, however Lake Tage and Tigi are unprotected. Further research is needed to determine if this species range does in fact extend beyond the Wissel Lakes and how it has been impacted by threats within its range.
