    Notes This count was done by reserve staff. ADU=613 only captured the data for this count and did not participate in the collection. The count was done from a boat and by vehicle. Access to a boat is becoming increasing problematic. Future counts are likely to be done on foot and using vehicles. Two back-to-back counts using the different approaches provide only a coarse indication of likely differences in coverage and numbers as counters also differed and heavy rain fell in the catchment of the dams between the two counts.
