About this site: BisonVsBuffalo.com is an independently produced educational resource. It is not affiliated with the IUCN, the National Park Service, the Smithsonian Institution, or any government agency or conservation organisation. We have made every effort to accurately represent the science and acknowledge uncertainty where it exists (particularly around contested taxonomy and population estimates). Where expert sources disagree, we note the disagreement rather than picking a side without justification.

Data accuracy and updates

Wildlife population estimates are subject to ongoing revision as new surveys are conducted and assessment criteria are updated. IUCN assessments are reviewed periodically; figures quoted on this site reflect the most recent published assessment as of April 2026. Specific figures for park populations (Yellowstone bison count, Kaziranga water buffalo estimate, etc.) are from the most recent published management reports and may differ from current census results.
