Pitcairn Island was discovered in 1767 by the British and settled in 1790 by the Bounty mutineers and their Tahitian companions. Pitcairn was the first Pacific island to become a British colony (in 1838) and today remains the last vestige of that empire in the South Pacific. Outmigration, primarily to New Zealand, has thinned the population from a peak of 233 in 1937 to less than 50 today.
deforestation (only a small portion of the original forest remains because of burning and clearing for settlement)
Geography - note:
Britain's most isolated dependency; only the larger island of Pitcairn is inhabited but it has no port or natural harbor; supplies must be transported by rowed longboat from larger ships stationed offshore
