061_1_2007_04 APR 2007 1

Photo Archive No. 061.1.2007.04

PS. 061. 09 April 2007. Facing north, Azimuth 10. Pasture 4. Elevation 1224 m. ISO 100, 35mm focal length, Canon 5D Digital Camera. Witness present, camera above. Mesquite alive, ocotillo, Calliandra in flower, catclaw small shrubs, and desert spoon far right midground. Fire burned lightly across view in 2005, small catclaw now resprouting, and many dead grass plants. Areas upslope and downslope burned hotter and dead mesquite in those areas. Lehmann lovegrass dominant with many small plants recruited recently, also find Boers lovegrass, and Setaria under mesquite. The distant right large tree present in 1914 was probably an oak, and the trunk of that plants appears to be present in the wash below original location. Barrel cactus far left survived 2005 fire. Compared to 2000, less grass, less cholla (did not survive fire) and bigger ocotillo. M. McClaran photographer, C. McMurtry assistant.

Photo Archive No. 061.1.2009.03

PS. 061. 18 March 2009. Facing north, Azimuth 10. Pasture 4. Elevation 1227 m. ISO 100, 35mm focal length, Canon 5D Digital Camera. Witness present, camera above. Mesquite alive, ocotillo, desert spoon far right midground. Lehmann lovegrass common, with Setaria, and cane beardgrass plants scattered; also find threeawns and a few cottontop. The area appears to have been covered with dodder in the recent past (probably 2 years ago because litter is grey in color) because litter includes that type of plant, and the density of grass has decreased and Calliandra is now absent compared to 2007. This absence is almost unique to this view because to the left and right, as well as up and down slope, there are no such bare-ground conditions. In addition, six sandbur plants (Cenchrus sp. perennial longevity) were found and dug-up (but not removed) to the immediate left and behind the few in this photo. First time I have seen that species on the Santa Rita. Compared to 2000, ocotillo in foreground is dead and on ground; no Calliandra present now; and four Yerba Santa (Baccharis pterinoides) are near the two Mimosa plants in the near center-midground area.

Yerba Santa (Baccharis pternioides) plants (n=3) behind velvet pod mimosa on right, and two prickly pear plants. Lehmann lovegrass dominant, Boer’s lovegrass common; Setaria, and cane beardgrass plants scattered; a few threeawns and cottontop; and plains lovegrass behand mesquite. No sandbur plants (Cenchrus sp.) were found. Compared to 2009, Calliandra present now; increase in Lehmann and Boer’s lovegrasses, and two new small mesquite plants in midground. M.
