Projects to Benefit Environment on the Southwest Border

Last edited 09/29/2021

Washington, DC – The U.S. Department of the Interior and U.S. Customs and Border Protection have completed the first InterAgency Agreement under the 2009 Memorandum of Agreement to fund environmental mitigation projects that will benefit several species of fish and wildlife affected by border security projects in the Southwest. Signed September 28, the agreement will fund $6.8 million in projects and represents the first of a series of efforts designed to mitigate impacts from the construction of fencing and other security measures along the U.S. Border with Mexico.

“CBP is committed to protecting our country's natural resources and wildlife while performing our security mission,” said CBP Deputy Commissioner, David Aguilar. “CBP is responsible for sound environmental stewardship and energy conservation as an integral part of their mission activities.”

“The projects we are announcing today are, in effect, part of a down payment on mitigating the impact on wildlife and its habitat from the on-going effort to secure our southern border,” Assistant Secretary Rhea Suh said. “In the future, we will continue to work with U.S. Customs and Border Protection to fund new projects that ensure threatened and endangered species and other wildlife along the border are conserved and the fragile ecosystems they depend upon are protected.”

The initial mitigation projects include funding to restore habitat for lesser long-nosed bats in Organ Pipe Cactus National Monument, Arizona; re-establish the Aplomado falcon in New Mexico; install a fish barrier at San Bernardino National Wildlife Refuge, Arizona to preclude competition with invasive species; study movement of bighorn sheep in California; survey and monitor jaguars and their habitat in Arizona.

Customs and Border Protection is funding these projects under a 2009 Memorandum of Agreement between CBP and the Department of the Interior for mitigation of unavoidable impacts to natural and cultural resources due to construction of border security infrastructure. Under this agreement, CBP will fund DOI up to $50 million over the next few years for mitigation needs.

Over the past three years, CBP has constructed about 670 miles of fence along the southwest border as an integral part of the nation's strategy to improve border security. CBP has committed to responsible environmental stewardship throughout the life-cycle of the tactical infrastructure, from construction through operations and maintenance.

The First Mitigation Projects:
a. Sasabe Biological Opinion Arizona
b. Organ Pipe Cactus NM Biological Opinion Arizona
c. San Bernardino Valley Mitigation Arizona
d. Rio Yaqui Fish Studies Arizona
e. Peninsular Bighorn Sheep Study California
f. Coronado NM Agave Restoration Arizona
g. Northern Aplomado Falcon Reintroduction and Habitat Restoration New Mexico $499,700
h. Border-wide Bat Conservation Arizona


U.S. Customs and Border Protection is the unified border agency within the U.S. Department of Homeland Security charged with the management, control and protection of U.S. borders at and between official ports of entry. CBP is charged with keeping terrorists and terrorist weapons out of the United States while enforcing hundreds of U.S. laws.
