to see Redonda, on his second journey. He claimed it for the Crown of Castile, but did not land there. He named the island Santa María la Redonda, meaning Saint Mary the Round, reflecting the island's apparent profile when viewed from the side. Because the island is a rock of just over a square kilometre, it did not represent any interest for the powers involved in the colonisation of the Americas and, for centuries, it was a refuge for pirates. In the 1860s, the island became a British possession. During the decades after the 1860s, the rich guano deposits of Redonda were mined for fertiliser, with an annual yield of up to 7,000 tons. Only during this time was the island inhabited by workers; the population was 120 in 1901. After the guano mining, aluminium phosphate for gunpowder production was discovered and mined. A cableway was constructed to transport material down to the loading pier on the coast. In 1914, during the First World War, the mining operations ceased, and most workers left the island. Maintenance workers remained on the island until 1929, when a hurricane destroyed almost all the remaining facilities. The island has remained uninhabited since then. Two stone huts still stand from the time when the island was occupied. Although the closest island to Redonda is Montserrat, and the second closest is Nevis, in 1967 Redonda became a dependency of the more distant Antigua, now part of Antigua and Barbuda. Scientists from the Montserrat Volcano Observatory visit the island in a helicopter periodically; they are using Redonda as an observation point from which to take measurements of the Soufrière Hills, an active volcano on Montserrat. Ecology and conservation Animals endemic to the island include the Redonda ground dragon, the Redonda anole and an unnamed species of dwarf gecko. The island is a breeding colony for multiple species of seabirds. The island's local ecology was severely affected by invasive species, particularly introduced goats and rats, for almost a century. Island restoration efforts were initiated in the 2016, beginning with removing the island's 60 goats and roughly 6000 rats. The Redonda Restoration Programme involves the Environmental Awareness Group, Wildlife Management International and Fauna and Flora International. Several years after the goats were removed, some local plant life began to recover. Micronation Redonda is the setting of the myth of the "Kingdom of Redonda". M. P. Shiel, an author of
