On June 11, U.S. President Donald Trump signed an executive proclamation to open additional commercial fishing grounds in remote areas of the Pacific. The proclamation says restoring access to these areas “will promote economic opportunity.” However, local groups warn it will open the door to overfishing in a crucial marine habitat and sacred cultural site. The proclamation, “Restoring American Commercial Fishing in the Pacific,” comes a year after a similar proclamation in April 2025 that opened up commercial fishing in the Pacific Islands Heritage Marine National Monument (PIH). Formerly the Pacific Remote Islands Marine National Monument, the PIH covers nearly 1.3 million square kilometers (500,000 square miles) of Pacific Ocean. The June 2026 proclamation includes portions of three additional marine national monuments — Rose Atoll, Mariana Trench, and Papahānaumokuākea —  which together include nearly 1.8 million km2 (690,000 mi2) of coral atolls, deep-sea trenches and remote islands.

Such commercial fishing could include kilometers of baited hooks, known as long lines, and purse seine nets more than 2,000 meters (6,600 feet) long. Both types of fishing gear are highly effective at catching tuna, the target species, as well as other marine life as bycatch. Conservationists say opening the Pacific monuments to industrial fishing is a significant concern for many species in the area, including threatened sea turtles, whales, dolphins, seabirds, sharks and fish; many are endemic, found…This article was originally published on Mongabay

U.S. President Donald Trump’s administration recently repealed the 2024 Public Lands Rule, which established that conservation should have equal priority with industry when it comes to accessing leases for U.S. public land. That shift in priorities will apply to 245 million acres (99 million hectares) of public land managed by the Bureau of Land Management (BLM). That’s roughly 10% of U.S. land that the agency leases for a multitude of private uses including grazing, mining, energy development and, until recently, conservation. In the federal register the Department of the Interior (DOI) said, “[b]y rescinding the 2024 Rule, the BLM eliminates mechanisms — such as restoration and mitigation leasing — that threatened to restrict productive use of the public lands.” An example of the decision’s impact can be found in the state of Montana. Roughly 950 American bison (Bison bison) have grazed on 63,000 acres (25,495 hectares) of federal land there since 2022. However, the DOI, which oversees BLM, revoked that grazing permit on May 8, just days before repealing the Public Lands Rule. Interior secretary Doug Burgman said that according to federal grazing laws, public land leases can only be given to animals, “intended for use primarily for their meat, milk, or other animal products.” He added that “considerable evidence” suggests the bison are intended for “for some other purpose, such as conservation.” Before western settlement, upwards of 100 million bison roamed the plains, serving as “ecosystem engineers shape[ing] healthy and diverse ecological communities,” the DOI acknowledged in its 2020 Bison Conservation…This article was originally published on Mongabay

When invasive rats are removed from islands, the ecological benefits can ripple across both land and sea more quickly than scientists expected, according to recent research. Scientists have long assumed that meaningful recovery after the predators are eradicated would take decades. However, researchers with the U.S.-based NGO Island Conservation conducted a rat-removal experiment on Ulong Island in Palau, which provides the first experimental evidence that ecosystems can rebound far more quickly than previously expected. Until recently, rats, which are typically nocturnal, were so abundant on Ulong Island that they were regularly seen during the day. They were a nuisance to campers and deadly for wildlife. As opportunistic omnivores, rats readily prey upon seabird eggs and chicks, devastating nesting colonies on tropical islands. As a result, there were “very few nesting seabirds that we would find,” Coral Wolf, the conservation science program manager at Island Conservation, told Mongabay in a video call. To measure the effects of rat eradication, Wolf designed an experiment in which all the rats were removed from Ulong, while the rats on nearby Ngeruktabel Island remained, serving as a control site. Before the eradication, researchers collected baseline biodiversity data. On land, they recorded bird calls and took soil samples. In the surrounding water, they measured indicators like fish biomass and coral cover. One year after rats were removed, the team repeated the survey and found a dramatic improvement in the biodiversity. Freed from rat predation, seabird activity on the island surged. Detections of bridled tern (Onychoprion anaethetus) calls rose by…This article was originally published on Mongabay
