Gibraltar Nature Reserve

The Gibraltar Nature Reserve (formerly the Upper Rock Nature Reserve) is a protected nature reserve in the British Overseas Territory of Gibraltar that covers over 40% of the country's land area. It was established as the Upper Rock Nature Reserve in 1993 under the International Union for Conservation of Nature's category Ia (strict nature reserve) and was last extended in 2013. It is known for its semi-wild population of Barbary macaques, and is an important resting point for migrating birds.
