| '''Dokdo''' is a small group of volcanic rocks located in the Sea of Japan. South Korea administers the islets as an area of the Ulleung County, Northern Gyeongsang Province. The 56-acre (226600 m<sup>2</sup>) formation consists of two main islands that house a lighthouse, a helicopter pad, and a small police force. Because the rocks shelter various species of birds, plants, and insects, the South Korean government has designated the islets as a nature reserve and enforces measures to protect the islets from the visiting tourists. The sovereignty over Dokdo has been contested by Japan over historical and legal grounds. The dispute between the two countries has been one of the more serious quarrels between South Korea and its former colonial ruler. In Japanese, the islands were called '''Takeshima''' (竹島) since at least 1905, and it means "bamboo island". The Korean name has many different transliterations in English, including "Tok-do", "Dok-to", and "Tok Islets" (<span style="font-family: Batang, Serif">독도</span>), which equate to "rocky island". The islets possess two English titles: '''Liancourt Rocks''' and '''Hornet Rocks'''. "Liancourt" has its origin in the name of the French whaling ship that first encountered and charted the islets in 1849.
