Will wall stop resilient San Pedro River from crossing the border?

By | 0 comments

The mighty San Pedro River in Southeastern Arizona and Northern Mexico has survived droughts, floods, fires and wars, but will the Trump Administration’s proposal to build a wall on the U.S.-Mexican border threaten one of the last undammed rivers in the United States? The river flows north out of Mexico and across the border into the United States near Hereford. The river has a rich cultural, ecological and historical record, and is the lifeblood to the small communities that have sprouted up along its banks. It also impacts a riparian area that is home to more than 250 migratory birds and more than 100 species of breeding birds, including the yellow-billed cuckoo.
