Livestock grazing prior to establishment of the Monument in 1988 also undoubtedly contributed to alteration of soils, loss of native grasses, and establishment of non-native plant species.

The Hagerman Fossil Beds paleontology crew has made some unusual finds. Early one summer the field crew found an articulated skeleton of a suckerfish (family Catostomidae) which was later jacketed and brought back to the lab for cleaning and study.
