Contributor/s

Justification
Myosotis atlantica is found at five sites and has an Extent of Occurrence of 8,000 km². The quality of its habitat is deteriorating resulting from increasing grazing pressure, cultivation and tourism development. The population trend is not known, but it is suspected that the more accessible sites are declining whereas the localities in the mountains are less threatened. The species is therefore classified as Near Threatened.
