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 both globally and for the EU27 Member States.

Myosotis soleirolii is endemic to Corsica (France) and Sardinia (Italy) with Paleotemperate origins. It is a rare species in the central mountains of Corsica from Rotondo to the Incudine Mountains. In Sardinia, it is found in the Gennargentu Mountains.

Myosotis soleirolii is known from 35 sites on Corsica. It was last 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 principally on granite.

There are no known significant past, ongoing or future threats to this species.

The species is not utilised.

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.

The species is assessed as Least Concern on the France national Red List (UICN France et al. 2018) and as Vulnerable for the Italian national Red List (Rossi et al. 2020).

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.
