Conservation status

The species C. lorenzoensis is classified as "Least Concern" (LC) on the IUCN Red List of Threatened Species.[1] Species are listed as such due to their wide distribution, presumed large population, or because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.[6]
