Rank ReasonsAllium gooddingii occurs in mountainous areas of eastern Arizona and central and western New Mexico including the Navajo Nation. High intensity fires of the 2010's have been shown to alter the habitat significantly enough to cause large declines, beyond the initial direct impacts to the species.
Range Extent CommentsAllium gooddingii occurs in Apache, Pima, and Greenlee Counties of Arizona including the White Mountains and Santa Catalina Mountains of southern Arizona; the Canyon del Muerto in the Navajo Nation and in New Mexico, the Mogollon Mountains of Catron County, as well as, areas of Lincoln, McKinley, and San Juan Counties.
Threat Impact CommentsWildfires are the greatest threat to Allium gooddingii. In 2011 and 2012, over 90% of all sites were burned in wildfires. It is also threatened by logging operations, grazing, road construction, and recreation impacts. It has been known to return after disturbance (Sabra Schwartz, pers. comm., August 1999) but high intensity fires that remove the canopy and alter the habitat cause declines after the initial setback from the fire, even site extirpations.The species does appear handle the direct impacts of fire. Indirect impacts of fire include invasion of aggressive native aspen stands and exotic herb layer species, and post-fire erosion of stream banks (Roth 2016).
