Sea Lion Haul-out 2 of 2

 branded sea lion

“The Steller Sea Lion Recovery Team recommended in 2000 that researchers begin branding and marking Steller sea lion pups throughout their range as a means to estimate vital population parameters in the future. Population parameters such as survival, age at first reproduction, and natality are important factors to understand population dynamics and gauge the health and stability of populations. Specific rookery sites were chosen to initiate these long term marking studies, both in the western and eastern stocks. For the eastern stock, three rookery sites were chosen in southeast Alaska (Forrester, Hazy and White Sisters) and 2 were chosen further south off southern Oregon and northern California (Rogue Reef and St. George Reef).” Patrick J. Gearin NOAA, AFSC, National marine Mammal Laboratory. Over the years we have seen sea lions with brands originating in both Alaska (Forrester) and California (Rouge Reef).
