  2. The effect and conservation implications of the re-establishment of a Cape fur seal Arctocephalus pusillus pusillus breeding colony at Vondeling Island, Saldanha Bay

    With regards competition for breeding space, Cape fur seals outcompeted African penguins and Cape cormorants. At the beginning of the study period, African penguins and Cape cormorants had bred in the interior of the island. An interior wall that was built for guano retention had also kept seals …
