The known biodiversity of tardigrades in North America is limited. Less than one-fourth of the known tardigrade species have been recorded in the United States. As part of the NSF-Biotic Surveys and Inventory and Research at Undergraduate Institutions programs we are attempting to expand the known biodiversity of North American Tardigrades by sampling 23 of America’s LTER sites. This work is a collaborative effort between Fresno City College, Baker University, Brigham Young University and the Academy of Natural Sciences Philadelphia.
