This segment of the U.S. - Mexico border wall spans from Naco, Sonora westward to the San Pedro Riparian National Conservation Area -- just a small segment of the 350 miles currently being constructed along nearly the entire length of the Arizona-California border with Sonora. The San Pedro River is one of the last undammed, free-flowing rivers in the American Southwest. The river and Conservation Area are known as one of the most biologically diverse areas in the U.S., hosting an estimated 83 species of mammals, more than 100 species of breeding birds and an additional 250 species of migratory and wintering birds. The border wall: 1) is planned to cross the San Pedro River and its floodplain, as well as over 60 seasonal streams and desert washes causing significant erosion and sedimentation into the river impacting habitat, 2) blocks wildlife movements that ensure healthy wildlife populations, with especially concerning impact on such rare and sensitive species as Sonoran pronghorn, jaguar, Mexican wolves, Mexican Black Bear and ocelot, 3) increases the likelihood that invasive species will colonize an ecosystem of international importance, 4) shifts undocumented migrant traffic, enforcement activities and associated degredation into adjacent wildlands, including rugged and ecologically-sensitive Sky Island mountain ranges (Sky Islands are tall mountain ranges that rise up from a "sea" of surrounding desert to support diverse ecosystems. These mountains receive enough moisture to sustain woodlands and forests, and provide niches for unique species that can only be found in these isolated "islands" of habitat.) www.defenders.org Will open in a new tab or window www.northernjaguarproject.org Will open in a new tab or window

    You say you are concerned about 350 species of animals affected? How about the 12 million illegals affecting 300 million citizens of our country! I live forty miles from here and see it every day! As far as your "Mexican Wolves" and "Jaguars", they haven't been seen anywhere near here since the early 1900's. Long before any wall was every put up.
