    The health of young Pinus hartwegii trees was compared in two national parks:  Ajusco and Zoquiapan.  Although both are located near Mexico City, Ajusco National Park receives the flow of polluted air after it passes through the big city.  The variables related to vigor in both locations were screened to detect those that are more explicative of the conditions of forest health:  crown color, needle retention, tree tip condition, needle damage, shape of trunk, and dwarf mistletoe infection.  In both locations, the trees were of the same diameter, but the Zoquiapan trees were younger and taller than those of the Ajusco Park.  The means for Zoquiapan were age 7.9 years and height 3.75 m, while for Ajusco they were age,10.3 years, and height 2.25 m.  The health of the Zoquiapan forest was better than that of the Ajusco forest, because the trees of the former had more natural green foliage, longer needles, sharper tips, less damaged needles, and better trunk shape.
