What corridor in southern Arizona is impacted by a new section of the US border wall?

The San Rafael Wildlife Corridor in southern Arizona is notably impacted by the new section of the US border wall. This area is known for its rich biodiversity and serves as a critical habitat for various wildlife species, including those that migrate through the region. The construction of the border wall can disrupt these natural pathways, isolating animal populations and interfering with their migration routes, which can have long-term consequences for ecosystem health and species survival.

The other options refer to different corridors or regions that, while they may face environmental challenges, are not specifically impacted by the recent construction of the border wall in the same direct manner as the San Rafael Wildlife Corridor. Each of these areas has its own ecological significance, but the San Rafael is particularly highlighted in discussions about the border wall due to its specific geographic and environmental implications.
