This specie is listed as Vulnerable in view of its restriction to montane streams above 2,000 m in north Tanzania, central and west Kenya and eastern Uganda. Pseudagrion bicoerulans is found in montane forest and in the ericaceous belt. These areas have National Park status at the larger mountains (Mt. Elgon, Mt. Kenya, Aberdare Mts, Mt Kilimanjaro, Mt Meru). The majority of the other highlands in western Kenya do not experience any protection and the forest reserve status of some areas is often just found on the map. There is deforestation outside the protected areas and this species is easily displaced by competitive lowland species.
