Abstract: Chihuahua pines (Pinus leiophylla Schiede and Depp e var. chihuahuana Eng elmann) were surve yed on 11 study plots on the Mogollon Rim in east central Arizona to compare characteristics of trees that sprouted from the base or root collar after the Rodeo-Chediski fire with those of trees that did not sprout. The differenc es in trees killed and top-killed by the fire versus those that survived were also assessed. Trees that sprouted were significan tly smaller in height and diameter at br east height; they also experienced lower fire intensiti es than trees that did not spro ut. Smaller trees had higher incid ences of mortality than larger trees. These resu lts indicate that, even though Chih uahua pine has fire resilien cy, sprouting rates after fire are related to size of trees, age of trees, and burn intensity. Since Chihuahua pine is a rare species in the area studied , its ability to recover from and tolerat e fire could prove advan tageous for sustainability.
