Nigerian conservationist Rachel Ikemeh has been named the 2026 Rolex Award laureate, for her work with communities in the Niger Delta to protect the region’s ecology and the critically endangered Niger Delta red colobus monkey. The red colobus (Piliocolobus epieni), a monkey known as epieni by the region’s communities, is listed as one of the world’s 25 most endangered primates by the IUCN, the global wildlife conservation authority. It was first described scientifically in 1993. At the time, there were about 10,000 epieni estimated to be living across its limited range in the Niger Delta. However, by 2013, their numbers had plunged to just hundreds rather than thousands of individuals, Ikemeh noted in a study. In 2021, Ikemeh and her colleagues helped establish a 1,010-hectare (2,496-acre) community-protected area for the epieni in Apoi, a town within the monkey’s range. By 2024, the monkey’s population had doubled within the community-protected forest, from 180-200 individuals in 2021, Ikemeh told Mongabay by email. She added the team has since helped create community conservation areas in the neighboring communities of Garnaut and Kokoloama. The award “feels less like a personal honour and more like validation for the community model itself,” Ikemeh said. She added she’s optimistic about the epieni’s future because she’s seen community perception around their conservation model shift over the years. “[T]he same community who once suspected we’d come to ‘collect their forest’ for the government now talk about epieni as a source of pride, something that put their village on the…This article was originally published on Mongabay

A U.S. federal court recently ruled that residents of Jackson, Mississippi, don’t have a constitutional right to truthful information from public officials, nor the right to municipal drinking water that is free of lead, a neurotoxin. “The Constitution does not provide redress for every governmental wrongdoing,” Judge Kurt D. Engelhardt of the U.S. Court of Appeals for the Fifth Circuit, who was appointed by U.S. President Donald Trump, wrote in the majority opinion. The case was brought by a group of Jackson residents in 2022 who alleged that the city allowed lead to enter the municipal water system and then lied to residents saying the water was safe, though they knew it was not. “Knowing what is in our water is fundamental to protecting public health,” Caroline Leary, general counsel at the U.S.-based nonprofit Environmental Working Group, told Mongabay by email. Jackson is home to roughly 150,000 people. Nearly a quarter of them are children under 18 who are particularly vulnerable to the potentially life-long toxic impacts of lead exposure including seizures, lowered IQ, impaired brain development and even death. The plaintiffs alleged that several of their children have been diagnosed with lead poisoning and now require special educational, medical, sociological, occupational and disability services. The plaintiffs also argued that exposure to contaminated water and the failure to be informed about the risks violated their 14th amendment due process right to bodily integrity. A November 2025 ruling by a three-judge panel of the Fifth U.S. Circuit Court of Appeals allowed…This article was originally published on Mongabay

Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. On the final day of a two-week expedition, where researchers were searching for a “lost” species along Papua New Guinea’s Sepik River, Helen Asu arrived with two small, greenish-brown fish. She had caught them while fishing for prawns with an umben, a traditional hand net, near Imbando village in East Sepik province. They were spinach pipefish (Microphis spinachioides), a species known only from the Sepik and not recorded by scientists since 1985, reports Mongabay’s Spoorthy Raman. “It was honestly an incredible moment,” said Jerrica Agebigo, a researcher at the Papua New Guinea University of Technology and the New Guinea Binatang Research Centre, who led the expedition. “When Helen showed the fish to us, I immediately realized that we had found something very special.” The spinach pipefish is a freshwater relative of seahorses and seadragons. It grows to about 15 centimeters (6 inches) and uses its elongated snout to catch small prey. Its coloring helps conceal it among water lilies and other plants along the banks of the Sepik, Papua New Guinea’s longest river. Almost everything else about it remains uncertain. The specimen used to describe the species was held at Hamburg’s natural history museum, but was destroyed during the second world war. When the fish was last assessed for the IUCN Red List in 2016, it was classified as data deficient. It later became one of the 10 most sought-after species on the…This article was originally published on Mongabay

Two species of trees helped Japan build millions of homes after World War II. However, pollen from those same trees has also fueled a nationwide hay fever allergy. More than 40% of Japan’s population now suffers from hay fever, locally called kafunsho. That’s nearly double the rate in the U.S., reports contributor Jonathan Vit for Mongabay. “Right after the New Year in January, my nose starts to get a little itchy,” Mariko Aoki, who works as a secretary at the National Diet, Japan’s legislature, told Mongabay. “It peaks in March, and the sneezing, runny nose, itchy throat and itchy eyes are really bad. It lasts all the way until just before Golden Week,” which runs from April 29 to May 5. Two tree species are largely to blame: sugi (Cryptomeria japonica) and hinoki (Chamaecyparis obtusa). Both are fast-growing trees that were widely planted for timber after bombing during the war left Japan in need of millions of homes. Today, forests cover roughly 70% of Japan, and 41% of those forests are planted. Sugi trees account for roughly 40% of planted forests, while hinoki accounts for another 25%. That means two-thirds of the nation’s cultivated forests are planted with trees that can make people sick. Climate change has made things worse: warming has driven sugi trees to release pollen earlier than they used to, making country’s annual pollen season longer and more severe. To solve its hay fever crisis, the Japanese government announced a plan in 2023 to cut down 20% of sugi trees…This article was originally published on Mongabay

Ocean ecosystems are under extreme stress on several fronts including overfishing, ocean acidification, climate change and marine warming. While ocean conservation efforts often tend to focus on creating marine protected areas, researchers recently stressed the need to move beyond protection toward active recovery using a different approach: Marine rewilding. In a new perspective paper, the researchers laid out eight key principles that can guide such rewilding. The concept of “rewilding” is usually applied to terrestrial ecosystems, where the goal is to restore ecological processes and create resilient, self-sustaining ecosystems with minimal human interventions. Gavin Stark, a post-doctoral researcher with the German Centre for Integrative Biodiversity Research, and his colleagues, write that one important principle of marine rewilding is that people can’t simply be fenced out of the process. “You cannot really separate people from the rewilding process inside the marine ecosystems,” Stark told Mongabay in a video call. Another key principle of marine rewilding is restoring food webs, which may include reintroducing top predators such as sharks. In 2024, for example, Mongabay reported on a project where eggs of the endangered Indo-Pacific leopard shark (Stegostoma tigrinum) raised in an aquarium in Las Vegas, Nevada, U.S., were shipped to nurseries in Raja Ampat, Indonesia. So far, the project has released more than 60 young sharks into the protected waters of Raja Ampat with the goal of restoring balance to the region’s coral reef ecosystem.  The authors note that along with restoring food webs, strengthening connectivity between ecosystems is also a pillar…This article was originally published on Mongabay
