Historically, Pectis imberbis (beardless chinchweed) has been found in the Atascosa-Pajarito, Huachuca, Patagonia, and Santa Rita Mountains in southern Arizona. In recent decades, only six U.S. populations have been located, five of which have fewer than 50 individuals in the population. Of the six surviving populations, Coronado National Memorial has one population that accounts for over 62% of the total population.
Last week BRN worked in Coronado doing some preventative care, hand-pulling patches of invasive grasses before they grew any larger or any nearer to the beardless chinchweed. New individuals were located and we established 48 monitoring plots. The plots will help us to better understand beardless chinchweed and inform future restoration practices. These plots will also be utilized by researchers at Northern Arizona University who are interested in pollinator-plant interactions with this very special plant.
