at risk of extinction critical risk of extinction VBO:0300014 Extinction status given to a group of animals that are at risk of extinction and for which the total number of breeding females is less than or equal to 100 (300 for species with low reproductive capacity); or the overall population size is less than or equal to 80 (240) and the population trend is increasing and the proportion of females being bred to males of the same breed is greater than 80 percent (i.e. cross-breeding is equal to or less than 20 percent); or the overall population size is less than or equal to 120 (360) and the population trend is stable or decreasing; or the total number of breeding males is less than or equal to five (i.e. ∆F is 3 percent or greater). 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.
