Bison bonasus (Lowland line): Vulnerable D1
In 2000, the total population was 931, not all of these are mature individuals. Although the population declined between the early 1990s and 2000, it is currently increasing.
Bison bonasus (Lowland-Caucasian line): Endangered C1+2a(i)
In 2000, the total population was 714, not all of these are mature individuals. The population decreased by >20% between 1990 and 2000, and has continued to decline since 2000. All subpopulations have fewqer than 250 individuals.
"The fate of the European Bison provides an example of the way in which a species may be brought to the brink of extinction in a very short time, and then saved only through great efforts. The saving of the bison has been an undoubted success, but further action to protect what remains a creature of relict distribution will continue to be essential" (Krasi?ski 2005).
