Some researchers contend the focus on chytridiomycosis has made amphibian conservation efforts dangerously myopic. A review of the data in the IUCN Red List found the threat of the disease was assumed in most cases, but no evidence shows, in fact, it is a threat. Conservation efforts in New Zealand continue to be focused on curing the critically endangered native Archey's frog, "Leiopelma archeyi", of chytridiomycosis, though research has shown clearly that they are immune from infection by "B. dendrobatidis" and are dying in the wild of other still-to-be identified diseases. In Guatemala, several thousand tadpoles perished from an unidentified pathogen distinct from "B. dendrobatidis".
