Ohridohauffenia rotonda is considered as Endangered B1ab(iii)+2ab(iii), as it is restricted to a single site, Lake Ohrid, with an area of less than 358 km2. The quality of habitat has been decreasing due to pollution and habitat degradation. It is a rare species usually found in low density and restricted to the littoral zone between 0 and 3 m depth, where current threats are affecting its habitat.
Ohridohauffenia rotonda is endemic to

|Population:||This species is only found in a few locations and mainly in low abundance (C. Albrecht et al. pers. comm. 2009).|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This is a freshwater species only found in edges of the lake in the littoral zone on banks and on stones.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
Deforestation of the neighbouring area leads to erosion and an increased sediment load changes the lake bed, smothering the rocks with cover of fine sediment. The water quality is also changing due to pollution (eutrophication, sedimentation, agricultural run-off) leading to habitat degradation. As eutrophication continues, the biofilm (algae) present on the hard substrate is changing, diminishing habitat and food availability for this small gastropod.
There is no current conservation action in place for this species. However,
