This report describes the results of ongoing population monitoring of New Zealand sea lions at the Auckland islands. This is the final report for the 2007/08 year.
The period covered in this report is from 4 December 2007 when the first team arrived on Enderby Island through to the departure of the second team from the Island on 15 February 2008.
This work continues annual surveys of the Auckland Island breeding sites of the New Zealand sea lions (Phocarctos hookeri). The projects objectives were to collect data to allow quantification and estimation of:
i) NZ sea lion pup production;
ii) survival of previously marked NZ sea lions;
iii) reproduction by known age female NZ sea lions;
iv) maintain and update the NZ sea lion database;
v) make available 2007/08 field data for relevant modelling work;
vi) characterise at-sea distribution of poorly known age and sex classes of NZ sea lions;
vii) to analyse data collected in vi above in a fisheries context.
