Conservation for Anthurium linganii must be considered as Least Concern (LC) according to IUCN Red List criteria (IUCN, 2001) because it is known from six collections and has been found in both Huainuco and San Martin Departments, Peru.

Anthurium linganii is known from the Departments of Huainuco and San Martin (Peru), ranging from 620 to 1100 m in elevation. This species grows in Tropical rain forest transition to Premontane (T-rf/P) and Tropical wet forest (T-wf) life zones.
