Deforestation in the Brazilian Amazon has fallen to its lowest level in 13 years, according to new satellite data from Brazil’s National Institute for Space Research (INPE), continuing a decline that began after President Luiz Inácio Lula da Silva returned to office in 2023. INPE’s DETER alert system detected 2,874 square kilometers (1,110 square miles) of deforestation in the Amazon between August 1, 2025, and July 31, 2026. That was 36% below the previous 12-month period and 55.6% below the average of the preceding decade. The total is the lowest since INPE introduced the current DETER system in 2015. Including data from its predecessor system, the last time alerts were lower was the 2012/13 deforestation year, when 2,766 sq km were recorded. Accumulated deforestation for Aug 1-Jul 31 in recent years according to INPE’s DETER alert system. Image by Mongabay DETER is designed as a rapid-response system for enforcement agencies. It uses satellite imagery to identify new forest clearing quickly enough for authorities to investigate and intervene. It differs from PRODES, INPE’s higher-resolution annual monitoring system, which provides Brazil’s official deforestation rate. Preliminary PRODES figures for the year ending July 31 are expected in October or November. PRODES data for the year ending July 2025 had already put Amazon forest loss at its lowest level in 11 years. The latest DETER figures indicate that clearing fell further during the following year. If PRODES shows a decline similar to that recorded by DETER, Brazil could register its lowest official Amazon deforestation…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. A harpy eagle needs large trees for nesting and enough surrounding forest for its young to learn to fly. The Amazon also depends on the eagle. By controlling populations of monkeys, sloths, and other animals, the predator helps limit damage to the forest canopy. Its decline can therefore indicate broader changes in the ecosystem. Governments often assess biodiversity by counting species. These figures are useful, although they don’t show whether an ecosystem is still functioning. A recent paper in Frontiers in Science argues that conservation policy should also track ecological processes, including predation, migration, pollination, and the movement of water and nutrients, reports Mongabay’s John Cannon. The authors propose using the Three Global Conditions Framework, developed in 2019, to decide what different landscapes require. It divides the planet according to the degree of human influence. Large, relatively intact areas need protection from new development. Landscapes where farming and settlements coexist with nature require management that maintains ecological functions. Heavily altered areas need restoration. The approach could help countries meet the Kunming-Montreal Global Biodiversity Framework, which calls for the loss of nature to be halted and reversed by 2030. Progress varies widely among countries. The agreement is not legally binding, and national governments determine how its targets are applied. The paper uses the term “nature positive” to describe an outcome in which ecosystems are healthier at the end of the decade than they were…This article was originally published on Mongabay

A tiger once put its head beside a passenger in Vinod Rishi’s jeep. Its face, he wrote years later, wore a “quizzical expression.” Then it moved away, leaving the men unharmed. Rishi called it “a King with a big heart.” Decades after the encounter, he could still recall the position of the tiger’s head and the look on its face. Rishi, who died in Dehradun on July 29, held some of the highest positions in Indian wildlife administration. He was the first director of Project Elephant, additional director general of forests for wildlife, and director of the Indira Gandhi National Forest Academy. During 38 years in the Indian Forest Service, he worked in the Sundarbans and Buxa tiger reserves, Jaldapara Wildlife Sanctuary, and the national parks of Singalila and Neora Valley. Born in Jalandhar, Punjab, he trained as an engineer at the Indian Institute of Technology Delhi and graduated in 1968. He joined the forest service the following year. His engineering background clearly influenced the way he approached conservation. He paid close attention to methods, evidence, and whether a plan would work in the field.  His early career in West Bengal brought him into contact with tigers, rhinos, elephants, and the administrative problems surrounding each of them. At Darjeeling Zoo, he studied animal biology at close range. The experience later contributed to work on captive breeding for snow leopards and the conservation of red pandas in Singalila. In the Sundarbans, he worked on conflict between people and tigers. When newspapers…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. Roads through Brazil’s forests divide primate habitat and sometimes force animals that normally remain in the canopy onto the ground. Researchers in the Amazon are testing rope bridges that allow them to cross above traffic. Eight bridges were installed in 2024 in Alta Floresta, in northern Mato Grosso state, reports contributor Suzana Camargo for Mongabay. Camera traps recorded 15,000 crossings by arboreal animals over the next 15 months. No roadkill was reported at the monitored sites. Six primate species used the structures, among them black-faced black spider monkeys (Ateles chamek), Schneider’s marmosets (Mico schneideri), and the critically endangered Alta Floresta titi monkey (Plecturocebus grovesi). The bridges contain several layers of rope for species with different forms of movement. Some walk across them, while others swing by their arms or use their prehensile tails. Cameras record successful crossings as well as animals that approach and retreat. The footage suggests that some species need time to become accustomed to the structures. Tufted capuchins took seven months to use one of the bridges. The work follows a project started in 2021 along the BR-174 highway, which passes through the Waimiri-Atroari Indigenous Territory. Members of the Waimiri-Atroari community helped select sites for 32 bridges. Cameras have recorded about 1,250 primate crossings there over the past five years, giving researchers information on which designs work best. Roads can also separate wildlife populations and reduce gene flow. This is…This article was originally published on Mongabay
