A follow-up survey in 1990 for EO #3 documented 11 flowering plants. Surveys in 1983 noted the prevalence of exotic species for EO #3 and by 1990 survey notes stated, "...heavy knapweed invasion where plants were ; In June 2002, the property containing both EO's was sold to the Montana Large Animal Sanctuary and Rescue, which uses the property to graze large numbers of llamas along with smaller numbers of other animals. A 2003 survey noted the area is "severely overgrazed and infested with noxious weeds" and the survey was unsuccessful in finding any S. spaldingii. An additional survey in 2004 near EO #4 did not locate any plants, and observed the area to be heavily grazed with the few plants present generally being weeds. A conversation with the organization's director in 2005 affirmed the use of the area solely for grazing "large domestic animals" and the unwillingness for future plant surveys to occur on the property. Due to these circumstances the ranks for these two EO's were changed to "possibly ; Even though S. spaldingii is known to be a long-lived perennial that may remain dormant for several years, these previously small occurrences appear to have little to no potential long-term viability or conservation value.
