The Washington status of Dunn's salamander is based on the small state range, narrow environmental specificity and concern that riparian habitats the species relies upon may not be fully protected. The need for retention of large woody debris is also of concern.
Sensitivity to climate change
Dunn's salamander is surface active a temperatures higher than its co-occurring lungless salamander congeners and its distribution going no further north than the Willapa Hills ecoregion partly reflects that. Few nest sites have been described, but the few found are concealed, so it likely that the few found represent the most accessible portion of typical nesting locations.
