Bever Dam Wash & Santa Clara River, Washington Co., Utah
July 8 Cottonwoods, 35-65 feet tall, 1-4 feet dbh. Mesquite and (cont.) trees, Russian olive (scarce) and Tamarisk (scarce) contributed to the woodland, as did Desert Willow. Creek willow was an unusual woodland component. Wash margins had Joshua Trees, mesquites, and luxuriant crested budwea. The N-S oriented wash divides slopes covered with crested bush with scattered Granite & other cacti and Joshua Trees. I visited the wash from 06:30 to 11:00, after Ranch leave walking the length of the Nature Conservancy property and about 1/2 mile of the wash on the adjacent property to the north. The only lesser goldfinch recorded answered my juncos birds as I was conversing with the property manager.
After leaving Beaver Dam Wash, I retraced my route back to the pavement, where I turned north toward Dunbrick, Utah. This road paralleled the Santa Clara River for about 16 miles, to its terminus at Utah State Highway 18; several dirt tracks left the paved surface toward the river and some of these I explored at least briefly. Former rice-grown irrigation woodland came right to the road edge, and I leisurely walked there. The woodland was mixed cottonwood-creek willow-ash-brolder, mostly medium size trees (25-40' tall, 1-2 1/4" dbh) but a few cottonwoods were big. Shrubs were mainly desert willow & coyote willow. Away from the riparian growth, vegetation was open, juniper-juniper woodland.
The drainage had little of bare rock exposed. Elevation about I visited from 17:00 - 17:30 3,500 ft. , Lots of old (reinstated by yesterday's rain) Crepice.
Weather today July 8, clear until noon when thunderclouds began to build in all directions; partly cloudy after 15:30.
No rain today. High N. Range until 22:30, then still; S freeze
