Botanical elements.

The purpose of this study was to conduct a preliminary survey of the botanical elements (vascular plants) in association with the Trinity River Basin from Fort Worth to the upper reaches of the proposed Tennessee Colony reservoir and from the damsite of the Tennessee Colony Reservoir to the upper reaches of the proposed Wallisville Reservoir. The vegetation in and around Lake Livingston was not included. The study focused upon the location of unique ecological areas which might merit future in-depth studies.
