In a profound challenge to federal environmental policy and tribal sovereignty, Native American nations are confronting a controversial reinterpretation of the 1973 Endangered Species Act (ESA) by the former Trump administration, a move that dramatically narrows protections for imperiled species across the United States. This federal action comes at a critical juncture for projects like the Swinomish Indian Reservation’s Smokehouse Tidal Marsh initiative, which, since its inception in 2022, has been diligently transforming 250 acres of erstwhile agricultural land back into vital estuaries and wetlands. This ambitious ecological restoration is a cornerstone of broader tribal efforts aimed at rejuvenating endangered and threatened populations of iconic species such as Puget Sound chinook salmon, Puget Sound steelhead, bull trout, and the majestic southern resident killer whales within the crucial Skagit River Watershed. The precipitous decline of these species, intrinsically linked to the health of their aquatic and riparian habitats, has been overwhelmingly attributed to relentless habitat loss and degradation spurred by unchecked development and intensive agricultural practices over the past century and a half.

Swinomish Tribal Indian Community Chairman Steve Edwards, a lifelong fisherman with over five decades of intimate connection to these waters, articulated the profound historical damage. "Over the past 150 years or so, there’s been significant damage to the habitat, and (the habitat is) what salmon needs," he stated, underscoring the fundamental connection between a thriving ecosystem and the survival of its inhabitants. This perspective, deeply rooted in traditional ecological knowledge, stands in stark contrast to the federal government’s recent policy shift. In July, the Trump administration dealt a massive blow to these painstaking tribal efforts, finalizing changes to the federal government’s interpretation of the landmark Endangered Species Act. The previous, widely accepted definition of "harm" to a species encompassed the habitat and essential resources a species requires to survive, reflecting an understanding of ecological interconnectedness. The new interpretation, however, radically curtails this scope, now defining "harm" solely as the intentional killing or physical harming of an individual of a species. This redefinition, which took effect on September 14, effectively guts the Act’s historical focus on ecosystem-wide protection, shifting it to a much narrower, individual-centric paradigm.

On July 14, the very day the rule change was finalized, the Swinomish and Squaxin Island tribes swiftly filed a lawsuit against the federal government, labeling the policy shift a "radical reinterpretation" of the law. Their legal challenge argues that the Trump administration’s changes flagrantly disregarded over five decades of established congressional intent and binding Supreme Court case law that consistently affirmed the ESA’s broad protective reach. The tribes articulated in their lawsuit the profound stakes involved: "Squaxin’s cultural and economic well-being depend upon the health and sustainability of Pacific Salmon and other freshwater and marine resources, which play a central role in the daily lives of Tribal members." This statement highlights not only the biological imperative but also the deep cultural, spiritual, and economic ties that Indigenous peoples maintain with their ancestral lands and waters.

Chairman Edwards revealed that federal agencies failed to respond to the Swinomish Tribe’s requests for government-to-government consultation regarding these significant changes, a profound breach of the United States’ inherent trust obligation to Native nations. This trust responsibility, a cornerstone of federal-tribal relations, mandates that the federal government act in the best interests of tribes, particularly concerning their lands and resources. "It feels almost like we’ve been betrayed by our federal trustees," Edwards lamented, expressing deep concern that the policy change directly diminishes tribal treaty rights. "It’s super disturbing that we had to fight this fight," he added, reflecting the frustration born from what is perceived as an avoidable and adversarial conflict.

This sentiment of betrayal resonated widely among Native nations, many of whom voiced strong opposition in public comments when the changes were first proposed in 2025. These comments consistently highlighted the alarming lack of meaningful tribal consultation, a recurring issue that undermines the principles of tribal sovereignty and self-determination. Tribes also emphasized the potentially devastating impacts the new interpretation could have on the recovery of countless imperiled species, many of which hold profound cultural, spiritual, and relational meaning and importance to their citizens. Beyond the ecological damage, the economic fabric of fishing communities could be severely disrupted, depriving those who rely on salmon and other aquatic resources for both commercial livelihood and subsistence, impacting food security and traditional lifeways.

The implications of this reinterpretation extend far beyond the Pacific Northwest’s iconic salmon. Tribes across the nation voiced concerns for a diverse array of species. The Pueblo of San Felipe, for instance, cited potential impacts on the monarch butterfly, a crucial pollinator, and Suckley’s cuckoo bumblebee, a lesser-known but equally vital insect. The Fallon Paiute-Shoshone Tribe in Nevada voiced grave concern for the Dixie Valley toad, a species they consider a relative, highlighting the deep kinship Indigenous cultures often share with the natural world. Cathi Williams-Tuni, Chairwoman of the Fallon Paiute-Shoshone Tribe, eloquently articulated the obvious: "It is obvious that removing water from a species that needs water to survive harms both individual members of the species and the species’ population." Her comments also underscored the specific threat posed by a nearby proposed geothermal project, which had been halted in 2022 after the Dixie Valley toad was listed as endangered. The Trump administration’s changes, however, could pave the way for its resumption. Williams-Tuni warned that "These harms in Dixie Valley would be catastrophic, permanently ruining the Tribe’s sacred site and ending the ability to use the springs for medicine and ceremonies," illustrating how environmental policy directly impacts cultural and spiritual practices.

In their lawsuit, the tribes have asked the court to prevent these regulatory changes from moving forward, seeking a decision that declares the changes unlawful and reverts to the previous, broader definitions of "harm." While they hope for a timely response, the tribes are prepared for the legal battle to potentially take many months to resolve, a testament to their unwavering commitment to protect their rights and the environment.

The new rule undeniably offers a significant advantage to developers and industrial interests. Under the previous interpretation, if an activity threatened to destroy habitat in a way that would harm a protected species, the responsible entity typically had to undergo a rigorous permit process. This process often triggered critical tribal consultation, allowing Indigenous nations to voice concerns, propose mitigation strategies, and protect their treaty-reserved resources. Under the new changes, such permits would be required much less frequently, effectively sidelining tribes from crucial decision-making processes and eroding their influence over projects impacting their ancestral lands. Furthermore, the revised definition now requires proof that the harm was intentional, a legal standard notoriously difficult to meet in cases of diffuse environmental damage. Bob Anderson, an Oneida Indian Nation visiting professor of law at Harvard Law School and a member of the Bois Forte Band of the Minnesota Chippewa Tribe, highlighted this challenge. "Companies won’t have any incentives to negotiate with the government or environmental groups or tribes about how their activities are going to affect the listed species," Anderson stated, pointing to the chilling effect on collaborative conservation efforts.

The repercussions could also destabilize large-scale agreements governing major river systems with ESA-listed species. Rivers like the Klamath, Elwha, and Columbia, for example, currently operate under complex agreements that mandate specific water releases from dams at certain times of the year. These releases are critical for supporting the migration and spawning cycles of endangered or threatened salmon populations, a requirement enforced by the ESA. The new interpretation casts a shadow of doubt over the legality and enforceability of these existing agreements, threatening to make salmon recovery exponentially harder. Kayeloni Scott, a Nez Perce and Spokane citizen and executive director of the Columbia River Snake Campaign, a powerful coalition of conservation groups, businesses, and the Nez Perce Tribe, emphasized the monumental task ahead. "We’re not even close to delisting these species," Scott asserted. "Our goal is abundance — healthy and abundant populations — that’s a whole other level, a whole other tier. Even getting to delisting, we’re pretty far off." This underscores that true ecological recovery goes far beyond mere survival; it aims for thriving populations capable of sustaining themselves and the ecosystems they inhabit.

Anderson also cautioned about the political risks involved in challenging federal policy, especially given the previous administration’s reputation for highly retaliatory actions. He cited the striking example of the Miccosukee Tribe of Indians of Florida, which joined a lawsuit against the administration in July 2025 over the construction of an immigration detention center in the Everglades. In December of that year, President Donald Trump vetoed an unrelated bipartisan bill that would have returned land to the tribe, explicitly citing the tribe’s opposition to the detention center as his reasoning. Trump called the Miccosukee Tribe "unaligned with my Administration’s policy of removing violent criminal illegal aliens from the country," sending a stark message. "That’s a real message there to plaintiffs that they’re going to retaliate against you," Anderson observed. "You’re locking horns with the federal government."

Despite the challenging legal and political landscape, Chairman Edwards remains resolute. His priority is the steadfast upholding of the Swinomish nation’s sovereign rights for future generations, a commitment deeply embedded in the intergenerational responsibility inherent in tribal governance. He affirmed that the tribe will not abandon its vital restoration work, irrespective of the federal policy changes. "It does impact our sovereignty," Edwards reiterated concerning the diminished species protections. "Generations down the road, I want (Swinomish citizens) to be able to exercise their treaty rights like I have done in the past." This unwavering determination underscores the enduring resolve of Indigenous nations to protect their environment, uphold their inherent rights, and ensure the well-being of their communities for millennia to come, even in the face of significant federal obstacles.
