The three breeds of Heidschnucke in order of population size include the German Grey Heath, White Polled Heath, and White Horned Heath. These groups form a category of moorland sheep native to northern Germany.
Main breeding areas are the north German heathland and moors of the Lüneburg Heath. This region serves as the primary habitat for these Northern European short-tailed sheep.
Moorland Sheep Day takes place every year on the second Thursday in July at Müden. This annual event celebrates the heritage of the breed through public display and commercial exchange.
The meat of the German Grey Heath is protected within Europe under this name and may carry the seal to show that it is a Protected Designation of Origin. Farmers rely on these protections to maintain viable flocks across northern Germany.
By selective breeding during the 20th century the breeds seen today were created and their weight virtually doubled. This process transformed lighter ancestral flocks into heavier animals better suited for modern agricultural demands.
