Most of the tree species that characterize riparian woodlands are early or facultative seral species including Fremont cottonwood (Populus fremontii), Arizona alder (Alnus oblongifolia), Arizona sycamore (Platanus wrightii), Modesto ash (Fraxinus velutina), boxelder (Acer negundo), and narrowleaf poplar (Populus angustifolia). Arizona walnut (Juglans major) is a riparian species that can persist at a low density in late seral or climax forests. The Southwest is a harsh environment for trees. The frequent occurrence of early-seral tree species in riparian forests reflect the frequency, severity, and extent of disturbance events. Disturbance from fire, seasonal flooding, and landslides all provide special opportunity for injury and infection by wood decay fungi.
