Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii) ver 3.1
Year Published: 2013
Date Assessed: 2009-11-25

Justification:
Turricaspia ismailensis is endemic to Ukraine and Romania.  In Ukraine where it is only present in two brackish water lakes that are interlinked with  an area of occupancy of 400 km2, is present in one location and is facing threats from pollution. In Romania there are at least 3 known locations, all in close proximity in the Danube delta therefore it has been assessed as Vulnerable (VU) B1ab(iii). Son (pers. comm. 2010) suggests this species maybe extinct in Ukraine, and that surveys are required to confirm that the species is still present in the upper lakes of the Danube delta. The main threats to this species are from pollution from heavy industry, sewage from domestic sources, agriculture in the catchment and dredging in the channels.

The species is also assessed regionally as:

European regional assessment: Vulnerable (VU) B1ab(iii)

Threats [top]

Major Threat(s): The main threats to this species are from pollution from heavy industry, sewage from domestic sources, agriculture in the catchment and dredging in the channels.

Conservation Actions [top]

Conservation Actions: There is no data is available on conservation actions for this species. Son (pers. comm. 2010) suggests that this species may be extinct in the Ukraine lakes, therefore surveys are recommended to confirm its presence. If the species is extant, management of the catchment to control the effects of pollution and habitat monitoring to measure its impact are recommended.

In Ukraine where it is only present in two brackish water lakes that are interlinked with  an Area of occupancy of 400 km2, is present in one location and is facing threats from pollution therefore it has been assessed as Endangered (EN B2ab(iii)).

In Romania, the status is Data Deficient, as there is no recent information on populations or threats to these sites.
