at risk of extinction vulnerable Extinction status given to a group of animals that are at risk of extinction and for which the total number of breeding females is between 1,000 and 2,000 (3,000 and 6,000 for species with low reproductive capacity); or the overall population size is greater than 800 (2,400) and less than or equal to 1,600 (4,800) and increasing and the percentage of females being bred to males of the same breed is greater than 80 percent; or the overall population size is greater than 1,200 (3,600) and less than or equal to 2,400 (7,200) but stable or decreasing; or the total number of breeding males is between 20 and 35 (i.e. the ∆F is between 0.5 and 1 percent). The criteria for this extinction status are defined by the United Nations’ Food and Agriculture Organization (https://www.fao.org/dad-is). Other international breed organizations might have other criteria for this status. VBO:0300018
