My photo documentation of the effects of the border wall on wildlife and the environment began in 2009. As recently as March, 2020, I was working along the Arizona border. There is a profound contrast between the barren strips of land bulldozed for the new walls and the yet undisturbed desert nearby where I photographed stills and video of a hummingbird bathing at Quitobaquito Springs, just yards from the boundary with Mexico. At dusk, not far from there, I surprised a bobcat hunkered down in an area where bulldozers were pending.
