Resolving data deficiency in a cryptic skink: distribution, threats, and an Endangered conservation status for the Bungle Bungle robust slider (Lerista bunglebungle)

A cryptic skink, the Bungle Bungle robust slider (Lerista bunglebungle), previously classified as Data Deficient by the IUCN Red List, has been reclassified as Endangered due to its restricted distribution and declining population. Researchers detected 21 occurrences of this species across the southern and eastern Bungle Bungle Range in Purnululu National Park, Western Australia. Using targeted fieldwork, spatial analyses, preserved specimen analysis, and inferred life-history traits from ecologically similar species, they determined that the skink's maximum Extent of Occurrence and Area of Occupancy is 280 km², with threats including changing fire regimes. The study underscores the urgent need to prioritize research on Data Deficient taxa, as many are likely threatened with extinction despite their uncertain status.
