Juncus kelloggii has been globally ranked by The Nature Conservancy of the U.S. as “G3?,” or vulnerable either because very rare and local throughout its range, found only in a restricted range (even if abundant at some locations), or because of other factors making it vulnerable to extinction (NatureServe web site 2001). 

The British Columbia Conservation Data Centre considers Juncus kelloggii  “red-listed,” or a threatened/endangered taxon (Douglas et al. 2002). This taxon is ranked as an “S1,” in British Columbia, or critically imperilled because of extreme rarity or because of some factor(s) making it especially vulnerable to extinction. Typically 5 or fewer occurrences or very few remaining individuals (<1,000) (BC CDC Tracking list web site 2002; Douglas et al. 2002).  Douglas et al. (2002) lists the global ranking as “G3”.
