The ドイツ語:Rote Liste, full name ドイツ語:Rote Liste der bedrohten Nutztierrassen im Bundesgebiet,〔 is a red list of threatened breeds of domestic animal published annually by the Gesellschaft zur Erhaltung alter und gefährdeter Haustierrassen,the German national association for the conservation of historic and endangered domestic animal breeds.〔 ==History== The GEH was founded in Witzenhausen, in Hesse, central Germany, in 1981. In 1987 it established the criteria on which the Rote Liste is based. The list is published annually, and attributes one of four categories of conservation risk to domestic breeds of cattle, dogs, goats, horses, pigs, rabbits and sheep, of chickens, ducks, geese and turkeys, and of bees; listing of domestic pigeon breeds is in preparation.〔 Some breeds from outside Germany are listed separately. The four levels of risk are: * I: ''ドイツ語:extrem gefährdet'', extremely endangered * II: ''ドイツ語:stark gefährdet'', seriously endangered * III: ''ドイツ語:gefährdet'', endangered * ''ドイツ語:Vorwarnstufe'', alert The risk level is calculated using a formula that takes into account five criteria: the number of breeding animals or breeding females; the percentage of pure-bred matings; the five-year trend in breed numbers; the number of breeders or herds; and the interval between generations of the animal.〔 The GEH also publishes, in conjunction with the , the German national association of poultry breeders, a separate list of the historic poultry breeds and colour varieties that were raised in Germany before 1930. The same levels of conservation risk are assigned as in the main red list.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rote Liste」の詳細全文を読む スポンサード リンク
