Screening for Batrachochytrium dendrobatidis in New Zealand native frogs: 20 years on

A chytrid fungus (Batrachochytrium dendrobatidis; Bd) has been a cause of amphibian declines worldwide. Batrachochytrium dendrobatidis was first detected in New Zealand on an introduced frog species in 1999 and two years later was associated with morbidity in Leiopelma archeyi, one of the three native New Zealand frog species. In this study, we aimed to document the prevalence of Bd in native frog species in New Zealand from 2014–2021.
