Foremost we thank Dr Robert C. Drewes who had the inspiration and fortitude to initiate, coordinate and lead multiorganism biotic surveys on São Tomé and Príncipe. We thank Eng.

We are indebted to Société de Conservation et Développement for logistics and housing support, especially the wonderful staffs of Omali Lodge and Bom Bom Island. We are grateful for the continuing support and cooperation of Bastien Loloumb of Monte Pico and Faustino Oliviera, director of the botanical garden at Bom Sucesso.
