Saint Helena was first visited by the Portuguese on May 21, 1502. The island’s diverse species lived in isolation from other places for a long time. Saint Helena was used by the Portuguese, Dutch, and British, and that constant use had devastating effects on the species there. Famously, Saint Helena is where Napoleon was sent for his second exile in 1815. He later died there. The Saint Helena petrel is only known from sub-fossils found on the island. It was also known as the Saint Helena gadfly petrel or large Saint Helena petrel. DNA testing indicated that it was its own unique species. Because it is only known from sub-fossils, it is believed that the Saint Helena petrel was hunted to extinction soon after people arrived on the island. Although Jurassic Park is fiction, scientists are working on several de-extinction projects. In fact, in 2003 scientists did bring back the extinct Pyrenean ibex, a type of wild goat, for 7 minutes before it died, showing de-extinction is possible. The Saint Helena petrel would not be a good candidate because there are no museum specimens available. Scientists have been able to extract DNA from sub-fossils, to do genetic testing, so it might be possible. There have been efforts to restore and conserve the ecosystems and species of Saint Helena that still exist there, especially in the cloud forests. To date, 36 species on the island have already gone extinct with many others facing extinction. If the Saint Helena petrel was brought to life, could it ever be reintroduced to its native homeland on Saint Helena in the South Atlantic?
