Abstract | Rising temperatures and more frequent droughts are posing new challenges to range livestock producers in the southwestern United States and many other parts of the world. We analyzed a 49-year time series (1969-2017) of precipitation, ambient temperature, and perennial grass production (PGP) as well as 14 years (2001-2014) of MODIS-derived vegetation phenometrics at a site in the Chihuahuan Desert of New Mexico. PGP was positively associated with December through September precipitation (r = 0.74; P < 0.05) but negatively associated |
