Some observations on Hochstetter's frog in the catchment of the Motu River, East Cape
The distribution and abundance of Hochstetter's frog (Leiopelma hochstetteri Fitzinger) in part of the catchment of the Motu River was assessed during two short surveys in 1981 and 1983. Specimens were found in most tributaries examined and on the banks of the main river, above extreme flood level. Crude indices of abundance were obtained by relating the numbers found to the time spent searching and number of stones and logs turned. Generally about four frogs were found per hour, but there was considerable variation in counts obtained in simultaneous searches by different observers.
