PATAGONIA NATIONAL PARK — Chile. Mongabay traveled to Chile’s Patagonia National Park to follow a women-led team on a mission to bring 13 Darwin’s rheas back to the wild in April 2026. Working with Rewilding Chile Foundation, these dedicated rangers care for the birds around the clock, facing harsh weather, predators like pumas, illegal livestock grazing, and other threats to the park’s fragile ecosystem. For more than a century, the Chacabuco Valley, where the park is located, was dominated by sheep and cattle ranching. Fences fragmented the vast Patagonian steppes and rheas (Rhea pennata) nearly disappeared. But one of South America’s most ambitious rewilding efforts is helping to turn the tide. Tompkins Conservation, the organization behind Rewilding Chile, acquired former ranchlands and began removing thousands of kilometers of fencing, allowing native wildlife to reclaim the landscape. Now, the team is preparing for another milestone: Releasing 13 Darwin’s rheas into the wild. Mongabay followed the rangers in the days leading up to the release, documenting their preparations, the challenges they faced, and their determination to give these birds the best possible chance of survival. Will they succeed? Watch the video to find out. Mongabay’s Video Team wants to cover questions and topics that matter to you.

Paraguay has provided updated information to the United Nations about the Chaco Biosphere Reserve, a protected area where deforestation from farming and cattle ranching threatens the survival of Indigenous communities. The country had until the end of September to respond to a UNESCO request to provide updated management plans and zoning, which critics say are only selectively enforced. There was no automatic consequence for not meeting the deadline, but UNESCO officials said they’re monitoring the site to ensure it doesn’t lose its designation. “We aim to provide member-states with the necessary technical support and opportunities to complete or improve their documentation, with the ultimate objective of ensuring strong and functional biosphere reserves,” a UNESCO official wrote in an email to Mongabay in September. The biosphere reserve covers approximately 7.5 million hectares (18.5 million acres) of the Gran Chaco, one of the largest tropical dry forests in the world. Millions of hectares of the biome have been deforested, most of it for farming and cattle ranching, over the last two decades. Much of the region is the ancestral territory of the Indigenous Ayoreo. The Ayoreo-Totobiegosode continue to live in voluntary isolation, making them especially vulnerable to outside disease where farms and ranches are expanding. They’re the last uncontacted Indigenous group in South America outside of the Amazon Rainforest. The biosphere reserve was established in 2001 and then expanded in 2011, partly due to the presence of Indigenous groups living in voluntary isolation. In 2005, it was included in UNESCO’s Man and…This article was originally published on Mongabay

Since Sept. 23, a group of rural producers has maintained a blockade on the road to the Paquiçamba Indigenous Land in the Volta Grande do Xingu region of Brazil’s Pará state. The blockade is supported by local politicians and aims to prevent government officials from physically demarcating the land traditionally occupied by the Juruna (Yudjá) Indigenous people. The protestors want to prevent the Indigenous Affairs Agency (Funai) from entering the area to physically mark the boundaries of the Paquiçamba. It’s a required step before the Indigenous territory can be officially approved by the president and formally registered. Paquiçamba is directly affected by the Belo Monte hydroelectric project and such federal demarcation of Indigenous land in the area was one of the conditions required for the project to receive environmental licensing. “The blockades have delayed the completion of physical demarcation work, which includes georeferencing, the placement of boundary markers on the Indigenous Land, and the installation of signage,” a Funai spokesperson told Mongabay over email. “Given this situation, Funai is seeking legal measures to guarantee the continuation of the work, access to the border areas of the Indigenous Land, and the safety and integrity of the teams responsible for the activities.” Even with support from the National Public Security Force, the spokesperson said clashes broke out between the blockaders and federal agents, interrupting their work. Ya Juruna, an Indigenous person from Paquiçamba, told Mongabay over WhatsApp messages that the protesters are trying to block her community from receiving legal rights to…This article was originally published on Mongabay
