Taiwan’s tallest tree found with help of citizen science

8 June 2026 at 20:46
Deep in Taiwan’s misty mountains, researchers have confirmed the tallest tree in the country: a thousand-year-old fir tree higher than a 20-story building, which they’ve named “the heaven sword of the Da’an River.” Climbers scaled the tree and dropped a measuring tape from the top to the forest floor during the Lunar New Year holiday in January 2023. The tree measured 84.1-meters (276-feet). The findings have been published in Frontiers in Forests and Global Change. A team of ecologists, geologists, remote-sensing specialists, professional climbers and Indigenous people that calls itself the “Taiwan tree seekers” began the search in 2014. “The common characteristics [of the team] are probably that we are all tree lovers and like adventures,” Rebecca Chia-Chun Hsu, lead author from Division of Forest Ecology, Institute of Taiwan Forestry Research, told CNN. ‘The Heaven Sword’, Taiwan’s tallest tree, measures 84.1 meters.

The island sits where the tropics meet the subtropics, and its mountains host several giant conifer species. The species behind the new record, Taiwania cryptomerioides, is known to the Indigenous Rukai people as “the tree that hits the moon.” Although nearly 60% of Taiwan is covered in forest, loggers cleared much of the island’s old-growth forest between 1912 and 1991. However, its steep slopes were too dangerous to reach, and pockets of ancient forest survived. Still, finding the tallest tree amid the rugged terrain was a task.

In Brazil, a project paying farmers for forests is looking to scale up

Landowner Carlos Roberto Simonetti gets three harvests per year from the corn, soy and cotton plantations on his 17,000-hectare (about 42,000 acres) farm called Fazenda Natureza Feliz, or Happy Nature, in the Brazilian state of Mato Grosso. Over the course of four years, he would also get what he calls a fourth harvest, this time from the forested areas of his property, located where the Cerrado savanna meets the Amazon Rainforest. That’s because Simonetti would receive regular payments for protecting native vegetation beyond what the law requires, as part of a pilot project for payment for ecosystem services (PES) run by the Amazon Environmental Research Institute (IPAM), an NGO, in the states of Mato Grosso and Pará. The program, called CONSERV, gives landowners financial incentives to keep the forest standing even in areas which they are legally allowed to clear. The pilot project, which initially ran between 2020 and 2024 on 23 different properties, protected 20,707 hectares (about 51,170 acres) of land in the Cerrado and Amazon biomes with funding from the governments of Norway and The Netherlands. Ongoing contracts funded by Soft Commodities Forum members – agribusiness companies committed to preserving the Cerrado – are protecting a further 7,000 hectares (about 17,300 acres) in the states of Mato Grosso and Maranhão. IPAM is now seeking to scale up the program without relying on donations. The risk of legal deforestation The idea for CONSERV goes back to 2016, when an internal IPAM report calculated that around 1.5 million hectares (3.7…This article was originally published on Mongabay
