The primary threat at this time is considered to be off road vehicle use (CNHP Scorecard 2006). Other threats are from other recreational uses, sheep grazing and its secondary impacts, mining, exotic species invasion, effects of small population size, glo
Total estimated sum of individuals from 1 of 2 documented occurrences is 1,100. The other occurrence is historical and does not report the number of individuals.
On USFS Sensitive Species list
From NatureServe: There are no data on population trends for G. sedifolia; however, there is currently no evidence of drastic population declines. Originally collected in 1892, then not recollected until 1995 by Sue Komarek. It is likely that other occurrences remain to be discovered, so more species inventory work is needed before the population trend can be accurately assessed (Anderson 2004).
