PS. 042. 20 April 2007. Facing south, Azimuth 205. Pasture 8. Elevation 1286 m. ISO 100, 35mm focal length, Canon 5D Digital Camera. No witness, cairn built, painted white, camera above. Blade of former witness post is present next to cairn. Matches all photo directions very well. Mesquite, catlcaw acacia, ocotillo, Calliandra, Krameria present. Prickly pear present. Cholla far right midground not evident in 2000. Lehmann lovegrass is only perennial grass. Same mesquite as 1936 and new mesquite immediately to right behind rock was possibly in 1956 photo. Ocotillos arrive between 1936 and 1956, many still alive in 2007, but one mortality on far left between 2000 and 2007. Compared to 2000, much less grass, mesquite less vigorous, less ocotillo and less prickly pear; also on top left distant slope, there is less tree cover since 2000 probably because of mortality associated with July 2005 fire. M. McClaran photographer, no assistant.
