Rationale
(Changed due to Same category and criteria)
Trithemis donaldsoni is a widespread species with no known major widespread threats and it is unlikely to be declining fast enough to qualify for listing in a threatened category. Therefore, it is assessed as Least Concern.
Distribution
Trithemis donaldsoni is common in the eastern part of Africa, from South Africa to Ethiopia. In southern Africa, this species occurs mainly in the northern parts of the region. In Namibia it colonises some artificial lakes, otherwise it is not found in the arid southwest or at the Cape. Former records from western Africa and Arabia (Yemen) are now ascribed to its sister species, Trithemis dejouxi Pinhey, 1978 (Dijkstra 2007).
No information is available on the population size.
Threats
The major threats to this species are habitat loss through drainage and destruction/deforestation of swampy habitats caused by agriculture, as well as water pollution.
Uses and trade
This species is not used.
Conservation
Research is needed on the population size and range, as well as monitoring of the population trend.
