Species Listed During Calendar Year 1991

Note: This report counts every species ever listed as threatened or endangered under the Endangered Species Act. The status of a species may have changed since it was listed; therefore, if the number of species listed each calendar year is added up, that total will be different than the total number of species currently listed under the Endangered Species Act. Experimental populations and foreign species are not included, but distinct population segments (DPS) are counted, as are species listed due to similarity of appearance and joint US/foreign listings. The effective date (as given in the Federal Register notice) is used to determine in which Calendar Year a species is counted.
