Census of annual pup production by Australian fur seal populations, Australia (1986-2015)

In Australia, it is thought that up to 26 Australian Fur Seal (Arctocephalus pusillus doriferus) colonies existed prior to the onset of commercial harvesting in the early 1800s [34]. The uncertainty regarding the number of colonies is caused by an inability to determine the exact location of all sealing locations and a lack of clarity as to which species was harvested [35]. At the end of commercial harvesting in 1921, fewer than 10 Australian Fur Seal colonies were extant with greatly reduced numbers of fur seals [35]. The number and size of colonies in south-eastern Australia have regenerated subsequently , but with 20 breeding sites identified in 2007 the population is still considered to be in recovery Data sourced from McIntosh RR, Kirkman SP, Thalmann S, Sutherland DR, Mitchell A, Arnould JPY, et al.

在澳大利亚，学界普遍认为在19世纪初商业捕杀活动启动前，曾存在多达26个澳洲毛皮海豹（Australian Fur Seal，Arctocephalus pusillus doriferus）聚居群落[34]。关于聚居群落数量的不确定性，源于无法确定所有海豹捕杀点的确切位置，且对当时被捕杀的物种界定模糊[35]。1921年商业捕杀结束时，现存的澳洲毛皮海豹聚居群落不足10个，且种群数量大幅锐减[35]。此后，澳大利亚东南部的聚居群落数量与规模得以恢复，但截至2007年仅确认20个繁殖位点，该种群仍被认为处于恢复进程中。数据引自McIntosh RR、Kirkman SP、Thalmann S、Sutherland DR、Mitchell A、Arnould JPY等（2018）的研究《Understanding metapopulation trends of the Australian fur seal, with insights for adaptive monitoring》，发表于PLoS ONE 13(9): e0200253，DOI: 10.1371/journal.pone.0200253。
