Justification: Myosotis soleirolii has a restricted distribution, but the populations appear to be stable, and it is not believed to approach the criteria for listing in a threatened category. It is therefore listed as Least Concern.
Myosotis soleirolii is an endemic species from Corsica and Sardinia with Paleotemperate origins. It is a rare species in the central mountains of Corsica from Rotondo to Incudine mountains. In Sardinia, it is found in the Gennargentu mountains.
Myosotis soleirolii is known from 35 sites in Corsica. It has last been observed at the site of Rotondo in 2007.
The populations are affected by the hydrological conditions, but the global trend is not known. The lower altitude populations are found in flooded areas, so if the water level drops these are likely to disappear.
The species is found on runnels, edges of streamlets from 160 m to 2,050 m of altitude. This Hemicryptophyte grows principally on granite. At the moment, information about germination, growing and flowering conditions is not available - more research is needed.
The species is legally protected on a regional level (Corsica) and is included in the French national Red List. Surveillance of the existing sites is done by guards from both the Regional Natural Park of Corsica and Botanical Conservatory from Corsica; search for new locations is underway. It is recommended to study the dynamics of different populations; to increase knowledge about its biology, resilience and conservation; and to collect seeds for ex situ conservation.
