| Abstract: | The African penguin Spheniscus demersus is endemic to southern Africa and is listed overall as "vulnerable". Over the past century, however, the Namibian population has been severely reduced and is currently listed as "critically endangered". Recent trends at Possession, Halifax, Ichaboe and Mercury islands, which account for 97% of the Namibian population, were examined using counts of moulting adults and active nests at peak breeding. Since 1996, the adult population has decreased at a rate of 2.6% per year. Since 1990, the breeding population has decreased by 3.7% per year. Mercury Island is the only Namibian breeding site where penguin numbers are increasing. Improving the conservation status of the species is critical. Better management strategies need to be identified and implemented. |
