In this report, a new index count for 2013 is presented along with population growth rate estimates from within and between the two regions of Vancouver Island and the central mainland coast. The Terms of Reference specifically for this document are: describe changes in the range of the sea otter in 2013 compared to previous assessments and compared to the historic range and since re-introduction in 1969-72; provide a minimum abundance estimate for the population in 2013; describe changes in abundance that have occurred since 2008, since 1969-72 and compared to historic abundance; estimate the population growth trend to 2013 in total and by area and compare to 2008 and since reintroduction in 1969-72. To address the specific request above regarding growth trends by area, growth rates were estimated for sub-regions that comprise the Vancouver Island range and the central mainland coast.
