PS. 244. 25 March 2023. 4:25 PM. Facing east, Azimuth 90. Pasture 10. Elevation 1275 m. ISO 200, 35 mm focal length, Canon 5D Mark II Digital Camera. No witness present, white paint rock cairn constructed (now near edge of road cut), camera above. This may not be a good match for images 1948-1956 because the size of the foreground mesquite in 1988 should have been present in the 1956 photos. Therefore, it is more likely that the location in 1948-1956 photos was further east ~10 m and looking slightly more to the south than the images starting in 1988. Mesquite alive, Calliandra common. Graythorn 30m behind foreground mesquite and a small one under foreground mesquite. Barrel and prickly pear cacti. Dasylirion, Lycium, and catclaw far left behind foreground mesquite. Agave distant center. Mimosa dysocarpa far left and right. Burroweed, shrubby buckwheat (far left), and flowering bluedicks present. Lehmann lovegrass dominant, also find sideoats grama, tanglehead, cottontop, and Boer’s lovegrass (far right), black grama, hairy grama (far right), threeawn, sprucetop and slender grama; and bush muhly under graythorn, Lehmann lovegrass and Setaria under mesquite. Good match with 1988 photo based on rocks in foreground. Large trees in early photos are present today in background. Compared to 2017, more grass cover and mass, especially Lehmann lovegrass increase; more grass species added including sideoats, black and hairy gramas, cottontop, tanglehead, and Boer’s lovegrass; less prickly pear cover and plants, and lost Krameria.
