The DOE BER Ecosystem-Scale Precipitation Manipulation Study in New Mexico is generating new insights concerning the effects of climate change on the structure and functioning of pinyon-juniper woodlands. The experiment (only partially visible here) increases and reduces precipitation inputs (±50% of ambient) as a means to discover links between drought, insect attack, tree mortality, and ecosystem ecology.
