The Control Site is located on one section (267 ha) that has not been thinned nor prescribed burned for many decades. It is typical of unmanaged stands in ponderosa pine forests of the southwestern US. Most old growth trees in the stand were harvested between 1914-16.

The stand currently contains trees from several regeneration cohorts; most overstory trees are about 87 years old. In 2006, tree basal area averaged 30 m2 ha-1, leaf area index (projected) averaged 2.3 (97% in trees), which is close to the maximum for southwestern ponderosa pine forests, and coarse woody debris averaged 13.3 Mg ha-1.
