Activity of amphibians is strongly related to meteorological conditions. The threatened giant burrowing frog is rarely encountered, even when it is known to be present in an area. To improve its detectability and so improve our ability to manage the species we wanted to determine the conditions under which this species is active. Thirty-three frogs were tracked over a 2-year period, their location determined daily and activity measured as the proportion of frogs moved from the previous day. Animals were found to be active throughout the year and activity was associated with rainfall, humidity, temperature and wind strength. The results suggest that surveys for this species should be carried out after rainfall of at least 5mm, when temperatures are above 8°C, relative humidity above 60% and in still or light wind conditions.
