Population
Recent surveys indicate that the South Island Hector’s dolphin populations collectively number about 7,270 individuals (CV = 15.8%) (Dawson et al. 2004; Gormley et al. 2005). The North Island subspecies is estimated to number about 111 (CV = 44%), and that population’s abundance and range appear to have been declining rapidly over the past 30 years (Slooten et al. 2006b; Dawson et al. 2001).
