[3] The Corsican red deer was introduced to the Tyrrhenian islands of Corsica and Sardinia during the Holocene by humans around 2500–3000 BC,[4] replacing the now extinct endemic deer Praemegaceros cazioti, which had been present on the islands for over 450,000 years.

Today, red deer live in the wild in sanctuaries on both islands; for example, it is bred in the Monte Arcosu Forest in Sardinia and in the Parc Naturel Régional de Corse, which covers almost 40% of the island, where it was reintroduced from Sardinia after its extinction in the 1970s.

At that time, the less than 250 animals that still existed on Sardinia were protected and plans were elaborated for a reintroduction on Corsica.

Reintroduction could finally begin in 1998, and as of 2007, the Corsican population was about 250 individuals, with a total of about 1,000 for the subspecies, which has therefore been downgraded to near threatened on the IUCN Red List.
