White rebar serves as witness, camera above and 4 m south of metal pegs for 1935 cut plot brush treatment. Large mesquite in left foreground probably under brush pile in 1935 photo. Large mesquite in right foreground outside of 1935 image and probably not cut in 1935 treatment because the plant is very large and shaggy bark present on many large branches. Few burroweed plants and snakeweed plants present. One catclaw center before wash. Barrel, prickly pear, cholla cacti. Lehmann lovegrass dominate open areas, cottontop, bush muhly, and Setaria under mesquite. No Bouteloua aristidoides because dry summer 2009. Windy conditions.
