The Washington Post on Sunday ran a feature on the conservation implications of the border wall, here.
Meanwhile, the reaction from much of the birding community remains a yawn or even - because of the incendiary nature of the immigration debate - active hostility to those on birding forums trying to discuss the impacts of the border barrier. Many have asked, 'Birds can fly, so what's the big deal?'
True, birds can fly over a fence, but that's not what we're talking about here. The border "wall" will actually be two walls, with a cleared, lighted patrol strip between, and cleared land on either side - a devastating loss of habitat, especially in areas like the Lower Rio Grande Valley of Texas, where habitat is limited to a narrow corridor along the river...a corridor conservationists (including the federal government) have spent tens of millions of dollars to restore, and the very corridor through which the wall would run.
Wings or no wings, birds need habitat, and the land on the southern side of the border, which will include most of the good riparian forest, will quickly become as degraded and the land currently on the Mexican side of the river. And good luck trying to get access to what used to be prime U.S. wildlife habitat, and which will suddenly require a border and river crossing to visit.
For species like the 70 remaining Sonoran pronghorn antelope, the endangered handful of Texas ocelots, or the newly returned Arizona jaguars, the wall would be a death-knell. Birders, I would hope, should be interested in more than just birds.
