Shoreline Revegetation Studies at Lake Texoma on the Red River Texas-Oklahoma

摘要

Three years of field studies were conducted at lake Texoma on the Texas-Oklahoma border to evaluate the suitability of selected plant species for use in reservoir shoreline revegetation projects. The plants were subjected to various inundation treatments and were monitored for survival and growth. Two field sites were established: one on the shoreline of Lake Texoma, the other in a nearby small impoundment where water levels were controlled by the researchers. Of 16 species tested, 11 demonstrated sufficient flood tolerance to merit consideration in shoreline revegetation programs in the south-central United States. Two herbaceous species, Arundo donax and Panicum virgatum, appear to be well adapted to a range of inundation conditions, including up to 7 weeks of growing season flooding. Woody species were generally less successful than herbaceous species, but several, especially Salix nigra, demonstrated considerable inundation tolerance. Summarized experimental data presented in this report should facilitate planting programs by providing an indication of species tolerances of a range of potential inundation depth and duration conditions.
