Broad-leaved deciduous cottonwoods, alders, and willows, and aspens line streamsides and canyons. Willows, alders, cottonwoods, and sedges are found in riparian areas. The canyon is vegetated by palm trees, cottonwoods, arroyo willows and eucalyptus. Willows and alders are followed by black cottonwoods, then Sitka spruce. Trees here include tamarix, ash, cottonwoods, willows and Joshua trees. Along lower elevation riparian corridors, cottonwoods and willows are typically dominant. The coulee environment is optimal for balsam poplars and narrow leaf cottonwoods. Hundreds of thousands of willows, alders, and cottonwoods eventually died. Willows and cottonwoods are the larger plants, joined by rushes and sedges. The Gros Ventres took shelter in a swampy thicket of willows and cottonwoods. Beavers cut willows, cottonwoods, and shrubs for food, and can significantly affect the riparian vegetation. There are also peachleaf willows and plains cottonwoods in the park. Forest trees include several species of oak, cottonwoods, ash, red cedar, elm, sycamore, and others. Many of these "cottonwoods" grew along the banks of San Antonio Creek. It is bordered by mature cottonwoods, agricultural land, and the Elmwood Cemetery.
