Blue palo verde right distant. Many rabbit feces in area. Compared to 2007, many small burroweed, left front cholla dead, Lehmann lovegrass in prickly pear, perennial grasses possibly unchanged but recent grazing (last month) give the appearance that abundance is reduced because almost all plants were defoliated.

Mesquite alive. Cholla, prickly pear, hedgehog and barrel cacti. Grasses include tanglehead, Lehmann lovegrass, threeawn; under mesquite find Seteria and cottontop. Ephedra right midground, and many smaller plants throughout. Blue palo verde right distant. Compared to 2011, barrel cactus in distant right is now dead, center cholla and right cholla are both larger; many new burroweed and others much larger; and much more tanglehead in the foreground. M. McClaran photographer, K. Hawkes assistant.

Mesquite alive. Cholla, prickly pear, hedgehog and barrel cacti. Mesquite trees on the far right and left of the 1948 image, are still present. Grasses include tanglehead, Lehmann lovegrass, cottontop, and threeawn; under mesquite found bush muhly, Seteria, and cottontop. Ephedra right midground, and many smaller plants throughout. Blue palo verde right distant. Compared to 2017, large increase in perennial grass cover and mass, especially Lehmann lovegrass and cottontop; added bush muhly; prickly pears are larger; burroweed are larger but fewer plants, and these were plants that established between 2011 and 2017; and decline in tanglehead in foreground.

Depression occupied by grass: tanglehead, cottontop, Lehmann lovegrass. Away from depression, Lehmann lovegrass dominates with Chloris. Under mesquite, find cottontop, Lehmann lovegrass, and bush muhly. Under left mesquite, find small blue palo verde. Most burroweed dead, a few small snakeweed. Prickly pear under right mesquite.

PS. 279. 14 March 2011. 9:35 AM. Facing west, Azimuth 290. Pasture 3. Elevation 1008 m. ISO 100, 35mm focal length, Canon 5D Mark II Digital Camera. Witness post present, camera above. Mesquite alive. Depression occupied by grass: tanglehead, cottontop, Lehmann lovegrass. Away from depression, Lehmann lovegrass is scattered. Under mesquite, find cottontop, Lehmann lovegrass, and bush muhly. Under left mesquite, find small blue palo verde. Most burroweed dead, a few small snakeweed. Prickly pear under right mesquite. Compared to 2007, many (greater than 25) small burroweed plants, prickly pear in right foreground in poor condition, palo verde under left mesquite has been browsed, perennial grasses possibly unchanged but recent grazing (last month) give the appearance that abundance is reduced because almost all plants were defoliated.

PS. 279. 15 March 2017. 10:15 AM. Facing west, Azimuth 285. Pasture 3. Elevation 1008 m. ISO 125, 35mm focal length, Canon 5D Mark II Digital Camera. Witness post present, camera above. Mesquite alive. Prickly pear and burroweed present; and a few small snakeweed. Depression occupied by tanglehead, cottontop, Lehmann lovegrass, threeawn, prickly pear and burroweed. Away from depression, Lehmann lovegrass, tangleheaed and cottontop are common. Under mesquite, find cottontop, Lehmann lovegrass, Setaria, tanglehead, and bush muhly. Prickly pear under right mesquite. Compared to 2011, more grass density and mass, especially tanglehead; blue palo verde is larger; burroweed density and size increase. M. McClaran photographer, K.
