Abstract
Old-growth ponderosa pine (Pinus ponderosa) forests are uncommon in the Southwest, and only one oldgrowth forest (the Gus Pearson Natural Area [GPNA]) has been researched in the ponderosa pine belt surrounding the city of Flagstaff in northern Arizona. The purpose of this study was to measure soil characteristics, current and pre-Euro-American settlement (1885) tree structure, and understory plant composition in a 6-ha remnant old-growth forest on volcanic, red cinder soils. Soil bulk density was extremely low (0.21 Mg/m3) in this forest because of high volumetric contents of cinders >2 mm diameter. As a result, volumetric soil moisture, organic C, and total N contents were low, with June gravimetric moisture (0-15 cm) averaging
