Environmental Groups Sue to Block SpaceX Boca Chica Land Exchange with U.S. Fish and Wildlife Service

STARBASE, Texas — A coalition of environmental and Indigenous groups has filed a federal lawsuit challenging the U.S. Fish and Wildlife Service’s approval of the “Boca Chica Land Exchange,” a deal that would transfer 715 acres from the Lower Rio Grande Valley National Wildlife Refuge to SpaceX near its Starbase operations in Cameron County, Texas.

The suit, filed on June 10 in the U.S. District Court for the District of Columbia, challenges the decision of the Director of the U.S. Fish and Wildlife Service, Brian Nesvik, to approve the exchange.

Under the deal, SpaceX will receive 715 acres of land from the U.S. Fish and Wildlife Service in exchange for 683 acres of private land, most of which would be added to the Laguna Atascosa National Wildlife Refuge to the West of Port Isabel.

So far, the Government’s position has been in lockstep with SpaceX, requesting that the Court expedite legal briefing on SpaceX’s motion to transfer the case to Texas.

Review and Approval by the U.S. Fish and Wildlife Service

The U.S. Fish and Wildlife Service, an office of the U.S. Department of the Interior, approved the exchange in June 2026 after completing a Final Environmental Assessment in May.

The Service’s 223-page assessment concluded that the land exchange would provide a net conservation benefit by consolidating fragmented refuge lands and trading lower-quality parcels for higher-quality habitat. The Service used Biological Importance Scores to compare the parcels and developed a Programmatic Agreement to address historic preservation concerns, including the Palmito Ranch Battlefield National Historic Landmark. The assessment also analyzed potential effects on threatened and endangered species.

The Lower Rio Grande Valley Refuge forms part of a long-planned network of protected lands along the Rio Grande intended to safeguard habitat for species including the endangered ocelot. According to the U.S. Fish and Wildlife Service, “The Boca Chica Beach and Starbase Units of the action area do not have vegetation characteristics necessary to support use by ocelots.”

Nonetheless, the environmental groups seeking to invalidate the exchange claim that it will divide one of the refuge’s largest contiguous parcels and enable further industrial expansion adjacent to Starbase that would destroy endanger a “habitat link” between the Lower Rio Grande Valley and Lagua Atascosa National Wildlife Refuges. They also raise concerns about impacts to the Palmito Ranch Battlefield National Historic Landmark and cumulative effects from SpaceX operations, including noise, light, and debris from occasional test anomalies.

Local organizations (and one not-so-local organization) leading the effort to block the deal

The lead Plaintiff seeking to block the Government’s Boca Chica Land Exchange with SpaceX is the Center for Biological Diversity, a 501(c)(3) non-profit organization based out of Tuscon, Arizona. The organization’s lawyers include Ivan R. Ditmars of Oakland, California, and Brandon Jones-Cobb of Seattle, Washington.

The Center for Biological Diversity is joined by two local environmental groups and one indigenous group—Save RGV, The Carrizo/Comecrudo Nation of Texas, Inc., and the South Texas Environmental Justice Network, all of Brownsville, Texas.

The same four organizations previously sued the Federal Aviation Administration over SpaceX launch operations near Boca Chica Beach. In that unsuccessful case, they argued that exploding rockets posed an ongoing threat to local wildlife. “Exploding rockets will keep raining down on the imperiled wildlife,” stated Jared Margolis, a Senior Attorney at the Center for Biological Diversity, following the failed complaint.

With a history of joining lawsuits targeting SpaceX’s operations in the Rio Grande Valley, The South Texas Environmental Justice Network has also promoted advocacy targeting U.S. Immigration and Customs Enforcement (ICE), border wall construction, and the liquid natural gas industry.

SpaceX’s On-the-Ground Stewardship

SpaceX has taken visible steps to maintain and improve the local environment around its Starbase operations. During the company’s Second Annual Fourth of July celebration on Boca Chica Beach earlier this month, SpaceX and its contractors worked to remove tires, automobile parts, chunks of wood, and other debris from the shore, leaving the beach clean and accessible for the public event. The effort was part of a broader push to ensure the celebration could take place on a debris-free beach while accommodating hundreds of visitors.

These actions reflect ongoing work by SpaceX to manage its footprint responsibly in a sensitive coastal area. The company has expanded its facilities while coordinating with local and federal partners on access, safety, and environmental considerations tied to its testing and launch activities.

Current Status

SpaceX has intervened in the case as a defendant and joined the federal government in requesting that the matter be transferred to a Texas federal court.

The Court has already ruled that SpaceX is entitled to intervene in the action and is actively considering SpaceX’s request to transfer the case to a Texas jurisdiction.

“SpaceXs standing is plain because if plaintiffs prevail then SpaceX will suffer injury caused by a judicial ruling to set aside the proposed land exchange,” wrote U.S. District Judge John D. Bates.

The case remains active, with further developments expected in the coming months as Starbase continues to grow alongside SpaceX’s broader efforts to advance its multiplanetary mission.
