Thurs, f. 1992 Journal Gita Alberts Big Bend Ranch State Park Site, Presidio Co Texas Elevation 3850 ft. May 22-27 went because eastern, and mesquites and other threes-cowboy trees pushed into the riparian gallery woodland. This experienced 150 yards is green, green, GREEN! Below here, the creek slope levels a bit and about 1/4 large Cottonwoods (t 20" Dbh, t 60' height) line the drainage, a few small mesquites are mixed. Blue bunch grasses first become numerous along the stream & strip road & continue so for the length of the wet. Here also the N. bank falls away from close proximity to the creek, and a slope of dense threes-cowboy grows on N. sides. A 30" Dbh, 55' Cottonwood stands on E. bank near the middle of a 50 yard discontinuity in the gallery, where any willows grow on N. side of the creek. Then begins 50 yds of ~closed canopy, cottonwood gallery woodland (mixed- age, (15-20" Dbh trees, all ~50' tall) Cottonwoods, at the lower end, making a large willows bridge a short opening to more such Cottonwoods. Hawthorn flecks found this strip. Juniper dominate the entrance to the woodland from the parking area at the end of the access road in the canyon cottonwood - 3'x4" Dbh, E 65'tall on N. bank. Below this the riparian corridor is dominated by willows punctuated by a few big Cottonwoods. The woodland becomes less continuous, until an isolated large cottonwood gives terminal punctuation to the green. Just below this, the water ceases to flow above ground, to resurface once again in the area of Los Cuevas. Gita Alberts is about 3.2 miles E. of Los Cuevas. I note also that green detritus in the riparian vegetation shows this very recently. The water level was 3-31/2 feet higher in the creek than presently. This must have been a sight to see! With refuges described, the remainder of these accounts will be a diary of daily movements and weather, with a terminal species list. The journal entry will need Big Bend Ranch but the specimens taken here will be labelled according to specific site.
