 In 2016, using a previously unknown Saccharomyces strain of yeast isolated from a beer bottle recovered from the wreck of "Sydney Cove" wreck, a beer called Preservation Ale, similar to Trappist Ale, has been brewed in name of the island.Nearly two centuries of grazing livestock, as well as frequent fires and consequent wind erosion, have severely modified the natural plant communities.The northern section of the island is infested with African boxthorn, with much of the rest covered by "Poa" and "Stipa" grassland.
