Contractors for the Department of Homeland Security (DHS) are currently adding around 50 small openings, often likened to “doggy doors,” to a section of the U.S.-Mexico border wall in Arizona and California.
Wildlife experts are already voicing concerns about this development.
They believe that the size of these openings, which measure about 8 by 10 inches, is insufficient and could potentially interfere with local ecosystems, preventing larger animals from migrating naturally. There’s a worry that this might lead to declines in animal populations or even starvation for those affected.
The openings are meant to allow smaller animals—like javelinas, skunks, and rabbits—to pass through. However, larger species, including mountain lions, jaguars, and bighorn sheep, will struggle to cross, raising significant concerns about their habitat connectivity.
Moreover, experts highlight that having only a limited number of these openings on such an extensive barrier is problematic.
The U.S.-Mexico border stretches approximately 1,933 miles, and around 700 miles of that have been fenced. The remaining sections are in various stages of contracting and construction.
Environmental advocates have expressed frustration. “This feels like a cruel joke,” said Ryken Jordahl, referring to the fact that just 50 openings exist for such a long wall. “There just aren’t enough of these small access points.”
Researchers Christina Aiello and Miles Traphagen recently visited the border wall for research. Their experience left them shaking their heads. “We were assessing the spot for future wall construction,” Traphagen mentioned. “Sacrificing our biodiversity and natural heritage isn’t the answer. We should be considering more constructive approaches to immigration challenges.”
To expedite the wall’s construction, DHS has waived several environmental regulations.
The agency stated, “These measures are vital for the swift building of physical barriers and roadways. The efforts under this waiver are crucial for securing our southern border and reinforcing our commitment to border security.”
In light of the criticism, a spokesperson from Customs and Border Protection (CBP), Matthew Dyman, asserted that the agency had consulted extensively with the National Park Service and other federal entities to determine the best locations for these openings based on existing species data and migration patterns.
