Table 3: Number of tortoises initially present in the crevices and the average over 160 sampling days
[NB: It was difficult to count the total number of tortoises in some crevices, especially the deep and narrow horizontal crevices (e.g. station 1, 3 and 5) since the tortoises at the front obstructed our view of the tortoises at the narrow rear part. For instance in station 5 and 6, four tortoises could be visible most of the time but when we eventually extracted them we found a total of six tortoises inside each of the crevices].
