Site Description

 

This 125 acre site is located in southwestern Bastrop County approximately 5 miles southeast of Red Rock. It is composed of three properties that form a rectangular unit with a panhandle on the northwestern half. It is less than ˝ mile from Bastrop County Site 2 and shares many similarities with some key differences. Red Rock Ranch Road, an unpaved road, runs along the northwestern extent of the site. Three seasonal creeks converge on the site, forming Sandy Creek. Topography is mostly rolling and not as steep as Bastrop County Site 2, though a nearly vertical cliff is present on the southern bank of Sandy Creek. Elevation ranges from over 670 ft above MSL on a hill near the northern end of the site to less than 550 ft near Sandy Creek. The site is relatively level to the northwest of this hill but falls quickly to the southeast toward the creeks. The site is fenced for livestock. All properties on the site are part of a large wildlife management cooperative centered around Red Rock.

 

 

Habitat Description

 

This site is located in a patch of loblolly pine forest that follows Sandy Creek and likely continued all the way to the “Lost Pines” near Bastrop historically, though it appears from aerial imagery that an unbroken connection may no longer exist. Pine forests in the area tend to occur in drainages and along creeks in deep, sandy soils where moisture is more available. Much of the site is dominated by loblolly pine. The associated post oak-blackjack oak-loblolly pine woodland that occurs in conjunction with pine dominated forests in the area occurs on higher, rockier sites. Much of the western half of the site is dominated by oak woodland with small natural openings offering much more of this habitat type than Bastrop 2. The two oaks are intermixed, though a single species tends to dominate each patch. The understory varies in density but is generally dense compared to Bastrop County Site 2. Yaupon holly (Ilex vomitoria) dominates with farkleberry (Vaccinum arboretum), American beautyberry (Callicarpa americana), black hickory (Carya texana), skunkbush (Rhus aromatica), sweet mountain grape (Vitis monticola), poison ivy (Toxicodendron radicans) and Virginia creeper (Parthenocissus quinquefolia). Herbaceous production is virtually nonexistent under the canopy due to a heavy duff (litter) layer. Very scattered examples of spurges (Euphorbia sp.), St. Andrews Cross (Ascyrum hypericoides) and milkpea (Galactia sp.) do occur. The scattered openings in the woodland, including some relatively large clearings near the western boundary, support more herbaceous production with a continuous herbaceous layer of little bluestem (Schizachyrium scoparium), partridge pea (Chamaecrista fasciculata), snake cotton (Froelichia floridana), western ragweed (Ambrosia psilostachya), and red lovegrass (Eragrostis secundiflora).

 

 

Soil Types

 

The property contains 3 soil types:

1.         PaE – Padina fine sand, 1 to 12 percent slopes

2.         SkC – Silstid loamy fine sand, 1 to 5 percent slopes

3.         JeF – Jedd gravelly fine sandy loam, 5 to 20 percent slopes 

 

Padina fine sand is a deep sand soil greater than 60 inches deep with moderate permeability and low available water capacity but good plant-soil moisture relationship. The surface layer is slightly acid fine sand up to 52 inches deep. It is classified in the Deep Sand ecological site. Climax vegetation is a savannah of post oak, blackjack, live oak, and hickory, interspersed with little bluestem, Indiangrass, switchgrass, sandhill lovegrass, brownseed and fringeleaf paspalums, sedges, lespedezas, tickclover, snowbean, partridge pea, and western indigo.

 

Silstid loamy fine sand is a deep sand soil greater than 60 inches deep with moderate permeability and available water capacity but good plant-soil moisture relationship. The surface layer is slightly acid loamy fine sand up to 28 inches deep. It is classified in the Sandy ecological site. Climax vegetation is post oak, blackjack oak savannah, with hickory, hawthorns, American beautyberry, little and big bluestems, Indiangrass, switchgrass, sand lovegrass, purpletop, uniola, paspalums, and panicums. Forbs include lespedezas, tickclovers, snoutbeans, butterflypea, milkpea, partridge pea, and tephrosia.

 

Jedd gravelly fine sandy loam is 20-40 inches deep with moderately slow permeability and low available water capacity. The surface layer is slightly acid gravelly fine sandy loam up to 12 inches deep. It is classified in the Sandstone Hill ecological site. Climax vegetation is a savannah and includes little bluestem, sand lovegrass, purpletop, sideoats grama, scribner panicum, post oak, live oak, elm, hackberry, bumelia, greenbrier, sensitivebrier, sagewort, and lespedeza.

 

 

Research Potential

 

This site offers a chance for research in an island of habitat that is isolated from the remainder of southeastern pine forests. The most prominent research interest in the Lost Pines area is the endangered Houston toad (Bufo houstonensis). Sandy creek is a possible corridor for expansion. Surveys could be conducted in the surrounding area to determine presence/absence and ponds could be created to determine likelihood of expansion and colonization of new habitat by the toad. Establishment of new populations through reintroduction to newly created pond habitat could also be assessed.

 

Bastrop County suffers from unusually low populations of white-tailed deer, even compared to surrounding counties. The Red Rock Wildlife Management Cooperative has successfully established and managed deer populations in the area with assistance from TPWD. This is one of a few pockets of increased deer densities in the county and would be valuable to compare to past studies in the Lost Pines to determine food habits and impact on the habitat, including reliance on supplemental food sources supplied by the cooperative.

 

Attwater’s pocket gopher (Geomys attwateri) is endemic to southeastern Texas, including Bastrop Co. and offers potential opportunities for research here. Previous genetic research has been conducted on the Lost Pines’ isolated population of Elliot’s short-tailed shrews (Blarina hylophaga) that are separated from other isolated populations along the Gulf Coast and in Oklahoma. These shrews are closely related to the Southern short-tailed shrew (Blarina carolinensis) of the southeastern US, but appear to be remnants of B. hylophaga populations. Surveys for their presence and collection of tissue for genetic analysis may help shed further light on the distribution and association of these two cryptic species.

 

There have been numerous sightings (confirmed by photographs) of at least four collared peccaries (Tayassu tajacu) in the area. This is within their historical range, but their presence this far north is no longer common. Examination of their possible source and comparison to more southern populations may shed light on their presence here and help determine if they are expanding their range.

 

The Lost Pines supports a unique and varied insect population, including nine species endemic to Texas and at least one recently discovered species of beetle, the Texas long-lipped beetle (Telegeusis texensis). Isolated habitats such as the Bastrop Pine Forests often spark development of new species and other undiscovered invertebrates may still occur there.

 

The suppression of fire from southern pine forests has resulted in stagnation of habitat. Research into the efficacy of fire in this westernmost example of southern pine forests and its impact on habitat and wildlife is important to future management of this unique area of Texas. This site could be used as a control or small test plots may be possible as a large ranch borders the site to the southeast, offering a buffer. The extent and impact of the 1978 fire on Bastrop 2 may be possible to determine as it appears Bastrop 3 was not impacted. Efficacy of various yaupon control techniques including mechanical and chemical methods may also be examined to determine methods other than fire which may aid management.

 

Any research conducted has the potential luxury of two sites (Bastrop 2 and 3) in close proximity to each other that offer similar characteristics with slight differences in habitat density composition that may offer opportunities for comparison.
