|Scientific Name:||Syncordulia gracilis (Burmeister, 1839)|
|Red List Category & Criteria:||Vulnerable B2ab(i,ii,iii); D2 ver 3.1|
|Reviewer(s):||Kipping, J., Simaika, J.P., Samways, M.J., Suhling, F. (Odonata Red List Authority) & Pollock, C.M. (IUCN Red List Unit)|
This species is rare everywhere in its range, and for a long time it has not been seen at many sites where it historically was present (e.g., Michell's Pass). With the removal of invasive alien trees, it has recovered at some localities (e.g., Franschhoek Pass), however it is still Vulnerable. It is known only from a few sites (around six locations).
|Previously published Red List assessments:|
|Range Description:||This species is endemic to South Africa. Two populations are known; one in the Western Cape, and one in the eastern Cape. It appears to have disappeared from Kwazulu-Natal, Drakensberg.|
Native:South Africa (Eastern Cape Province, KwaZulu-Natal - Possibly Extinct, Western Cape)
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||Population size is unknown, but the population appears to be stable at present.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||Montane streams and rivers, with undisturbed fynbos margins. Clear, fast, hard-bottomed rivers in treeless river valleys (Samways 2006).|
|Major Threat(s):||Invasive alien trees are the most important threat. Agricultural activities that cause river siltation and pollution and alien fish may also be a threat.|
|Conservation Actions:||No specific measures are in place or envisaged. However, conservation of catchments through the removal of alien invasive trees is clearly beneficial for this species and research into population numbers and range, and trends/monitoring would also be valuable.|
