the island is on average 70–90 meters deep, with the deepest point being at cape Šilo, where a depth of 107 meters has been recorded. Climate and natural history The island is also notable for the bora wind (locally known as bura) which blows in gusts on average 203 days per year, and even reaches force of 11-12 on the Beaufort scale (indicating a violent storm or hurricane-force winds) 73 days per year, according to weather records which used to be kept by the lighthouse crew. Because of this, Prvić is considered the windiest Croatian island. Although the island is uninhabited, it is frequently used by shepherds for pasture and by local beekeepers who keep apiaries on the island. Prvić and parts of the nearby island of Krk are areas with the highest concentration of Common sage (kadulja) shrubs in the entire Croatian Adriatic, and honey produced by bees feeding on the plant's nectar is prized for its quality. Griffon vultures, a protected bird species, are known to breed at Prvić, and their colony on the island is second in size only to their main breeding ground on the island of Cres, to the south of Prvić. The island marks the northern boundary of their coastal habitat. In addition, there are 17 species of endemic plants which grow on the island. Because of this the island of Prvić is legally protected as a botanical and bird reserve.
