Oryx (Oryx gazella) were introduced into southern New Mexico, USA on the White Sands Missile Range (across the San Andres Mountains) during the late 1960’s. Today, groups of these non-native herbivores can be found throughout the Jornada Basin. This oryx stands among the honey mesquite (Prosopis glandulosa) and soaptree yucca (Yucca elata) on the Jornada Basin LTER site on a June morning.

Researchers at the Jornada take measurements using a pantograph, where a researcher with a stylus (center) traces the outline of a plant in a plot and the contraption translates the movements onto a piece of paper outside of the plot (bottom right).


Research methods for some extremely long-term datasets at the Jornada remain consistent to ensure data continuity. Here, the same photo in the same location with a new generation of researchers was recreated in 2016, updating the 1935 snapshot.
