Plants were growing on the dune edge of the Sanctuary at the intersection of Villa Maria Isabel Avenue and Sand Dollar Avenue. | 27.62564900, -97.21972000 | 3 | Plants are growing in part shade to full sun, deep sandy, and dry conditions. Plants are sheltered from direct impact of winds and surf by the dunes where they reside. The dunes appear relatively stable with a dense "motte" of Quercus fusiformis and other plants species, all of which appear to quite mature. Soils: The soils of this site are classified as Galveston and Mustang fine sands, occasionally flooded (Gm). The Galveston Series (~50%) consists of very deep, somewhat excessively drained, high saturated hydraulic conductivity (rapidly permeable soils) that formed in sandy eolian deposits derived from igneous, metamorphic and sedimentary rock. These nearly level to strongly sloping soils occur on back-barrier flats on barrier islands. Slope ranges from 0 to 3 percent. The soils are occasionally flooded with salt water during severe storms. The Mustang Series (~30%) consists of very deep, poorly drained, very slowly permeable soils that formed in sandy eolian and storm washover sediments. These nearly level soils are on planar to concave barrier island flats. These soils are subject to occasional flooding by high storm surge from strong tropical storms and are ponded after periods of heavy rainfall. Slope ranges from 0 to 1 percent. Galveston and Mustang fine sands range from slightly alkaline to moderately alkaline. (Source: California Soil Resource Lab/NRCS Official Soil Series Descriptions). Geology: The underlying geology of this area is characterized as Barrier Ridge and Barrier Flat Deposits of Quaternary, Holocene origin. It is comprised of sand, silt, and clay; mostly sand, well sorted, and fine grained with abundant shells and shell fragments. Interfingers have silt and clay in landward direction; includes beach ridge, spit, tidal channel, tidal flats, washover fian, and sand dune deposits. (Source: USGS Texas Geologic Map Data). Slope: 1 to 5 percent. Aspect: west to northwest. | Wild material | | 2191652 | NA 89113 |

The area is disturbed, but somewhat overgrown since there is very little traffic on the road that is primarily used by farmers and ranchers to access their fields. Slope: 0 to 1 percent. Aspect: N/A. Soils: The soils of this area sampled are classified as Laewest clay, 0 to 1 percent slopes (LaA). The Laewest Series consists of very deep, moderately well drained soils that formed in clayey flood basin deposits on alluvial plains or deltas of the Beaumont Formation of Pleistocene Age. These nearly level to gently sloping soils are on broad flat coastal plains. Slope ranges from 0 to 8 percent. The solum thickness is more than 200 cm and ranges from slightly acidic on the surface to neutral in deeper pedons. This is a cyclic soil and undisturbed areas have gilgai microrelief with microhighs 15 to 30 cm higher than microlows. Distance from the center of the microhighs to the center of the microlows ranges from about 1.2 to 4.9 m. The microhigh makes up about 20 percent, the intermediate, or area between the knoll and depression about 50 percent, and the microlow about 30 percent. The amplitude of waviness between mollic colored materials in the upper part of the solum and the higher value colors in the lower part ranges from about 30 to 150 cm. When dry, the soil has cracks 1 to 5 cm wide at the surface and commonly 1 cm wide cracks extend to a depth of 1.2 m during the summer. The cracks remain open for less than 90 cumulative days in most years. Some pedons have an overwash of calcareous clay or silty clay 20 to 51 cm thick.

It is comprised of sand, silt, clay, and minor amount of gravel. Iron oxide and iron-manganese nodules are common in zones of weathering; locally calcareous. Surface is fairly flat and featureless except for many shallow depressions and pimple mounds. Moore and Wermund (1993a) mapped three units--(1) alluvium undifferentiated as to texture and origin--includes meander belt, levee, crevasse splay, and distributary sand, and flood-basin mud deposits, about 60 m thick, (2) fine-grained channel facies (alluvial sand, silt, and clay) about 10-25 m thick, thicker seaward, and (3) fine-grained overbank facies (alluvial silt and clay) about 55-65 m thick, thicker seaward. Together, these deposits form a deltaic plain that parallels the Gulf Coast. Unit contains Pleistocene vertebrate fauna, dips seaward beneath the Beaumont Fm. and disconformably overlies deposits of the Pliocene and early Pleistocene Willis Formation. The deltaic plain is entrenched as much as 7 m by streams. In Hidalgo County (southernmost part of Texas) the unit underlies a semiarid plain, widely irrigated and cultivated. Unit is locally veneered with thin, discontinuous stabilized eolian sand. (Source: USGS Texas Geologic Map Data). | Wild material | | 2191653 | NA 89114 |
