Photograph of poison weed plots on the Texas Agricultural Experiment Station. Members of the Texas Section, American Society of Range Management view the enclosures while on a field tour. Livestock were excluded from the area since October, 1951. Various locoweed control treatments have been tried. One outstanding result of the enclosures is in the recovery of cane bluestem grass. The area receives a little extra water from the adjacent highlands. Outside the plot the few cane bluestem plants found were closely grazed. Blue grama and buffalo grass predominated. Inside the enclosure, bluestem predominated in spots, with a great increase in vigor and the number of plants. TX-48-350.
