Measurements of tree characteristics were used as indicators of overstory structure on four oak woodland sites in southeastern Arizona. Three areas harvested at different times and intensities were compared with an undisturbed area to assess effects of harvesting on various structural attributes of woodland overstories. Structural vegetation changes affect habitat quality and thus wildlife populations in modified areas. Significant differences were found for some woodland structural characteristics between harvested areas and an undisturbed area. Structural changes persist, as prolific coppice sprouting produces shrub-like trees, which appear to take a relatively long time to reach mature height and form. Managers might be able to moderate impacts of harvests on woodland structure by adjusting harvest intensity, and multiple-use management objectives for some species of wildlife still might be met.
