Ascension Island’s Novel Ecosystems
I was standing on the summit of an extinct volcano in the center of one of the most remote islands on the planet: Ascension Island in the tropical South Atlantic. Midway between Brazil and Africa, Ascension is a thousand miles from the nearest speck of land. Below me was a harsh treeless moonscape of volcanic clinker, baking in the sun. But in the cool mountain air, 800 meters up, I was surrounded by lush greenery and a light mist from a cloud settled over the mountaintop.
They call it Green Mountain. But the greenery is new. My guide, the island’s conservation development officer, Stedson Stroud, peered around us and smiled. “Nothing you see here is native,” he said. “Except for a few ferns, everything has been introduced in the past 200 years.”
