This sentence presents a specific statistic that may not be common knowledge and is not the author's original idea, so it requires a citation to give credit to the source of this information.

The sentence " There were buffalo in every western territory of the United States as of 1860." requires citation because it presents a claim or fact that is not common knowledge and needs to be supported by a source
