We analyzed the near-riparian zone along the Colorado River in the Lampasas Cut Plain (LCP) of Texas at Timberlake Biological Station (TBS) and described species composition and structure of vegetation. Our analysis was conducted to provide baseline knowledge on the natural vegetation of this near-riparian zone that has only been examined from North Texas in the Piney Woods ecoregion. The near-riparian zone of TBS was comprised of three vegetational layers: 1) upper canopy of trees including mainly green ash (Fraxinus pennsylvanica) and about equal amounts of cedar elm (Ulmus crassifolia) and American elm (U. americana) 2) under canopy of the liana saw greenbriar (Smilax bona-nox) as well as both annual and perennial grasses and forbs. Green ash was the dominant tree and saw greenbriar and Virginia creeper (Parthenocissus quinquefolia) were the only two lianas. Dominant grasses and sedges included Canada wildrye (Elymus canadensis), switch grass (Panicum virgatum) and William Emory’s caric sedge (Carex emoryi). The dominant forb was Spiny-aster (Chloracantha spinosa). In addition, beaver damaged fewer trees in the near-riparian of the Colorado River and diversity was lower compared to a near-riparian zone in the Piney Woods and compared to bottomlands found in the West Cross Timbers ecoregion of Texas.
