Using site-occupancy models to prepare for the spread of chytridiomyosis and identify factors affecting detectability of a cryptic susceptible species, the Tasmanian tree frog

Research using site-occupancy models reveals that large populations of the Tasmanian tree frog (Litoria burrowsae) are more likely to be found in naturally formed ponds and are less prone to chytridiomycosis, a deadly fungal disease caused by Batrachochytrium dendrobatidis. The study also identified that strong winds and time after sunset negatively impact the detectability of these populations. Conducted within the largely disease-free Tasmanian Wilderness World Heritage Area (1.40 million ha), this work highlights the potential of site-occupancy modeling to improve conservation efforts by providing more accurate and efficient surveillance for cryptic species vulnerable to disease. The findings, though limited by the small number of Bd-positive sites recorded, underscore the importance of proactive monitoring in remote regions to prepare for potential disease spread.
