    PS. 75. 09 April 2007. Facing east, Azimuth 112. Pasture UA Cell. Elevation 1141 m. ISO 100, 35mm focal length, Canon 5D Digital Camera. Witness present, camera above. Mesquite alive, 50% burroweed dead, small catclaw in center midground, 2 Celtis behind, the second Celtis with graythorn in canopy; behind those find a large mesquite. No cacti. Lehmann lovegrass dominant with many small plants recently recruited, also find bush muhly under mesquite. Not confident this matches 1911 photo because Celtis in that photo are not present. Original probably upslope from here. Compared to 2000, less grass and less burroweed. M. McClaran photographer, C. McMurtry assistant.

Mesquite alive, small catclaw in center midground, two Celtis behind, the second Celtis with graythorn in canopy; behind those find a large mesquite. No cacti. Lehmann lovegrass dominant with many small plants recently recruited, also find bush muhly under mesquite. Not confident this matches 1911 photo because Celtis in that photo are not present; the original is probably to the north about 100 m. Compared to 2007, more Lehmann lovegrass and threeawns, and decrease in Bouteloua aristidoides. M. McClaran photographer, A. Peterson assistant.

Mesquite alive, and leaves emerging. Small catclaw in center midground, two Celtis behind, the second Celtis with graythorn in canopy; behind those find a large mesquite; and littleleaf baccharis far left. Burroweed scattered throughout. Small cholla throughout, and two barrel cacti in right distance. Lehmann lovegrass dominant with many small plants recently recruited, also find cottontop in open and under mesquite, bush muhly bush muhly and Setaria under Celtis. Not confident this matches 1911 photo because Celtis in that photo are not present; the original is probably to the north about 100 m. Compared to 2009, more Lehmann lovegrass and establishment and growth of many burroweed plants. M. McClaran photographer, K. Hawkes assistant.

    PS. 75. 19 March 2021. 3:46 pm. Facing east, Azimuth 112. Pasture 11A. Elevation 1143 m. ISO 125, 35mm focal length, Canon 5D Mark II Digital Camera. Witness present, camera above. Mesquite alive. Small catclaw in center midground, two Celtis behind, the second Celtis with graythorn in canopy; behind those find a large mesquite that died since 2015; and littleleaf baccharis far left. Two barrel cacti in right distance. Lehmann lovegrass dominant with many small plants recently recruited, also find cottontop in open and under mesquite, bush muhly and Setaria under Celtis. Not confident this matches 1911 photo because Celtis in that photo are not present; the original is probably to the north about 100 m. This area burned in April 2017. Compared to 2015, following very dry and hot conditions between July 2020 and March 2021, very little grass production in summer 2020 and very little green grass present now; more Lehmann lovegrass, fire removed burroweed and cholla plants, and killed some large mesquite including far right and far left plants and many in distance.
