Flora and Fauna
When Corporal William Glass and his family became the first settlers at Tristan da Cunha in 1816, goats and pigs were brought to Inaccessible Island to serve as a source of food. They remained there for at least 57 years and helped to keep the Stoltenhoff brothers alive during their expedition, but they have now died out. Cattle, sheep, and dogs were also introduced to the island at various points in the island's history, but none remain.
No land mammals, reptiles, amphibians, butterflies, or snails have recently been found at Inaccessible. The island does have 64 native plant species, including 20 types of flowering plants and 17 species of ferns. In addition, 48 invertebrate species exist on the island, 10 of which were introduced. Subantarctic Fur Seals and Southern Elephant Seals have also been seen at the island in increasing numbers, and whales live in the surrounding waters.

Famous quotes containing the words flora and/or fauna:
“A man’s interest in a single bluebird is worth more than a complete but dry list of the fauna and flora of a town.”
—Henry David Thoreau (1817–1862)
“The whole fauna of human fantasies, their marine vegetation, drifts and luxuriates in the dimly lit zones of human activity, as though plaiting thick tresses of darkness. Here, too, appear the lighthouses of the mind, with their outward resemblance to less pure symbols. The gateway to mystery swings open at the touch of human weakness and we have entered the realms of darkness. One false step, one slurred syllable together reveal a man’s thoughts.”
—Louis Aragon (1897–1982)
