Opinion

UNITED STATES DISTRICT COURT FOR THE DISTRICT OF COLUMBIA

CENTER FOR BIOLOGICAL DIVERSITY, et al., Plaintiffs, Civ. A. No. 1:26-cv-2053 (JDB) v. BRIAN NESVIK, in his official capacity, and UNITED STATES FISH AND WILDLIFE SERVICE, Federal Defendants,

SPACE EXPLORATION TECHNOLOGIES, CORP., Intervenor-Defendant.

MEMORANDUM OPINION

This case concerns a proposed land exchange between the U.S. Fish and Wildlife Service

and Space Exploration Technologies Corp. (“SpaceX”) regarding the Lower Rio Grande Valley

National Wildlife Refuge (“Rio Grande Refuge”) and the Laguna Atascosa National Wildlife

Refuge (“Laguna Atascosa Refuge”), both located in Cameron County, Texas. Plaintiffs—Center

for Biological Diversity, Save RGV, Carrizo/Comecrudo Nation of Texas, Inc., and South Texas

Environmental Justice Network—sued the U.S. Fish and Wildlife Service and Brian Nesvik, in his

official capacity, challenging the proposed land exchange and seeking injunctive relief and a

declaratory judgment. SpaceX moved to intervene as a defendant in this action, and the Court

granted its motion.

Presently before the Court are the government’s and SpaceX’s motions to transfer this

action to the United States District Court for the Southern District of Texas. Defendants argue that

1 transfer is warranted because this action concerns land in Texas, the work and decision-making

has been largely concentrated in Texas, and the proposed exchange would have a direct impact on

the people and environment of Texas. Because plaintiffs could have brought this action in the

Southern District of Texas and convenience and the interest of justice weigh in favor of transfer,

the Court will grant the motions to transfer.

BACKGROUND

The Rio Grande Refuge was established for “the development, advancement, management,

conservation, and protection of fish and wildlife resources” and currently comprises over 103,000

acres of land, including the 11,500-acre Boca Chica Tract. Decl. of Leston Stewart Jacks (“Jacks

Decl.”) ¶¶ 7, 9, Dkt. 14-1. It “provides critical habitat for species protected under both the

Endangered Species Act and the Migratory Bird Treaty Act.” Compl. ¶ 70, Dkt. 1. The Refuge is

not only an environmental sanctuary but has historical and cultural significance as well. It overlaps

with portions of the Palmito Ranch Battlefield, the final battle site of the Civil War and a designated

National Historic Landmark, id. ¶¶ 79-81, and includes Boca Chica Beach, used by the

Carrizo/Comecrudo Tribe of Texas as sacred land for “ceremonial life ways,” id. ¶ 14. Today, the

Refuge and SpaceX facilities neighbor each other, and SpaceX owns several parcels of land within

the Refuge. Jacks Decl. ¶¶ 9-10.

Plaintiffs are a mix of nonprofit environmental and cultural heritage organizations. Compl.

¶¶ 12-15. Three of the four plaintiffs—Save RGV, Carrizo/Comecrudo Nation of Texas, Inc., and

South Texas Environmental Justice Network—are based in Texas. Id. ¶¶ 13-15. The fourth

plaintiff—Center for Biological Diversity (“the Center”)—is headquartered in Tucson, Arizona,

with an office in Washington, D.C. Id. ¶¶ 11-12. The D.C. office includes the Center’s government

2 affairs program, which conducts lobbying efforts related to this land exchange and other issues.

Opp’n at 7-8, Dkt. 21.

Defendant U.S. Fish and Wildlife Service (“the Service”) is a federal agency headquartered

in Washington, D.C., that oversees the National Wildlife Refuge System and manages the Rio

Grande and Laguna Atascosa Refuges. Compl. ¶ 24. Defendant Brian Nesvik, the Director of the

Service, manages the National Wildlife Refuge System and is based in Washington, D.C. Id. ¶ 23;

Opp’n at 1. Intervenor-Defendant SpaceX is incorporated in Texas and has significant operations

and facilities throughout Texas. Decl. of Justin Styer (“Styer Decl.”) ¶¶ 5-6, Dkt. 15-2. And since

2014, SpaceX has been acquiring land near Boca Chica to develop Starbase, its headquarters and

rocket launch facility, which was incorporated as a new city in 2025. Jacks Decl. ¶ 12; Styer Decl.

¶ 6.

In 2023, the Service and SpaceX began discussions of a proposed land exchange.1 Compl.

¶ 92. The goal of the exchange is to “reduc[e] the fragmented ownership of the Boca Chica Tract

and consolidat[e] lands for management by the Service.” Jacks Decl. ¶ 13. SpaceX seeks to use

the land it may acquire for “residential, commercial, industrial, and infrastructure purposes,”

further expanding its operations in Cameron County. Styer Decl. ¶ 14. To date, the exchange has

been managed by the Service’s Southwest Region Office located in Albuquerque, New Mexico,

and the South Texas Refuge Complex Office based in Alamo, Texas. Jacks Decl. ¶ 26.

As required under the National Environmental Policy Act, Rio Grande Refuge staff

conducted an Environmental Assessment in consultation with Texas-based stakeholders to analyze

the potential impacts of the exchange. Jacks Decl. ¶ 20; see also 42 U.S.C. § 4336(b)(2); U.S. Fish

1 The Service has authority to exchange land under the National Wildlife Refuge System Administration Act, which “provides that the divested land must be ‘suitable for disposition’ and the value of the land exchanged must be approximately equal.” Jacks Decl. ¶ 22; see also 16 U.S.C. § 668dd(b)(3).

3 & Wildlife Service, Final Environmental Assessment (May 2026) (“EA”) 46-48, Dkt. 11-3.

Following a public comment period, on May 21, 2026, Leston Stewart Jacks, Acting Regional

Director of the Service, Southwest Region, signed a Finding of No Significant Impact (“FONSI”)

approving the proposed land exchange. U.S. Fish & Wildlife Service, Finding of No Significant

Impact and Decision for Lower Rio Grande Valley and Laguna Atascosa National Wildlife Refuges

Boca Chica Land Exchange (May 21, 2026) (“FONSI”), Dkt. 11-4.

As it stands, the exchange would transfer around 715 acres of land owned by the United

States from the Rio Grande Refuge and Palmito Ranch Battlefield to SpaceX. Compl. ¶¶ 1, 134;

FONSI at 2. In exchange, SpaceX would provide approximately 683 acres of land it privately

owns to the United States to be added to the Rio Grande Refuge and Laguna Atascosa Refuge.

Compl. ¶ 1; FONSI at 2.

Since the exchange is larger than 40 acres, it must be approved by the Director of the

Service. Jacks Decl. ¶ 25; see also U.S. Fish & Wildlife Service, Fish and Wildlife Service Manual,

342 FW 5.7.C. While these motions were pending, the Director approved the exchange. U.S. Fish

& Wildlife Serv. Decision Mem. at 8, Dkt. 26-21; Pls.’ Notice of Filing of Director’s Approval,

Dkt. 27.2 And now, because the land is worth over $1 million, the proposal must be sent to the

House and Senate Committees on Appropriations for a 30-day examination period. Id. at 3; Opp’n

2 The government has moved to strike plaintiffs’ notice of the Director’s approval on the grounds that it is a procedurally improper surreply. Gov’t’s Mot. to Strike, Dkt. 30. Plaintiffs have now opposed that motion. Pls.’ Resp. to Mot. to Strike, Dkt. 32. The Court agrees with plaintiffs. Motions to strike are “a drastic remedy that courts disfavor.” Moore v. United States, 318 F. Supp. 3d 188, 190 (D.D.C. 2018) (citing cases).
