Limpia Creek Section (formerly, Padre River), Davis Mountains State Park, Jeff
Davis Co., Texas. Elevation 5000 ft
June 15-21 The flat flood plain on this S. side of the creek is in contrast to the steep,
(Craig)
sloping hill opposite. The southwest facing slope is covered with native grass
than this side & has less robust-looking brush except in a couple ravines
where some vertical basaltic outcrops & an E.-facing slopes. There are some
scattered oaks and junipers, with one fair concentration of oaks in a south-
east draining ravine. The hill appears to top out about 300 ft above
the creek. Limpia Creek itself is without any significant gallery forest
in this stretch—only our small cottonwood, Syc-Willow is too common
plant—growing usually 4-6 ft high—at the stream's near margins.
Mostly the creek is naked gravel & cobbles. The stream itself is very
cold, and has filamentous green plants growing on the bottom and (less regularly)
on the margins. The stream flows for long stretches above ground but is
discontinuous upstream. Isolated pockets of surface water are particularly
choked to algae.
Downstream 250 yards the floodplain narrows to about 50 yds. Between
camp & this desert willow is common and hackberry reaches a medium size
and forms respectable copses, certainly large enough to encompass&
shelter a mist net, especially where there are some walnuts admixed.
Hackberries do likewise upstream, where there are also a few soapberries
and minosa, but there are also several large oaks on the far bank of
the creek upstream, where the drainage swings to this side of the flood plain.
Here, too, could make decent net sites.
Beginning downstream about 2/3 miles, on private property, and continuing
for several miles, Limpia Creek has an impressive gallery forest of very
close cottonwoods. Floods & cattle have taken & kept out the industry in
some places, however. There are still cattle in this stretch too—sheep.
