Big Bend Ranch State Natural Res. 20 miles E. of Presidio Presidio Co., Texas
May 22-27 when I collected birds.
(cont)
The main road runs almost perfectly E <> W from the entrance gate to
Ranch Headquarters, a distance of about 20 miles, traversing in its course
the low Boquillas Mountains. Kelly wanted me to look at water-influenced
places near the main road. These are Corra Larga, Las Cuevas, Ojitos
Abierto and Torque de los Ojitos, which are spread out over 16 miles along
the road and are listed in sequence W <> E. The desert slopes & flats
at this season are in full green foliage, concealing their arid nature and giving it
an undercharacteristic (to me) "soft" look. Cretotricha perhaps the commonest
plant, but ocotillo (growing in "forests" almost in some places), catclaw,
white-thorn acacia, honey mesquite, white bur sage, cholla's, prickly pear
(some w very large pads), several other low-growing (up to 14") cacti app.
cactus-app.
Echinocactus esp. near gypsum rock outcrops, and at least 2 types of yuccas are
common local members of the Chihuahuan Desert flora. There is some desert
wilder in the washes, and some greasewood and quite a few wildflower blooms
are also notable. The higher slopes are relatively ungrazed, especially
those facing S. & W.
Corra Larga is a natural seep draining into a concrete cattle trough.
Surrounding this are large mesquites and another large thorny tree whose id.
I cannot provide. Scattered in the immediate vicinity are catclaw acacia &
sage-pursley, and many other small shrubs of the Chihuahuan throughout
community. Uplands on a table land 15 ft above the tank and two adjacent
wash are some Larrea flats. A few ocotillo are present here. The N-
facing slope is backed by a 25-30 ft vertical rock face, cacti species bearing
small tingias draining the hollows below small pin-off points in the cliffs.
