The tallest measured specimen is with a
circumference of , which is believed to be about 400 years old, discovered near
Jari River in
Inipuku (municipality of
Almeirim, Para state) in 2019. It is the largest tree of South and Central America, and also the largest broad-leaf tree of all the Americas. The discovery was made using
airborne laser scanning (ALS) and field verification in Paru State Forest, which is shared by the Brazilian Amazon basin states of Amapa and Para. On 7 October 2022, a group of researchers after several failed attempts managed to reach the tree and measured a circumference of . The record breaking specimen was found in the 22 million-hectare (54.3 million-acre) Paru State Forest, which is part of an extremely remote area of the southern
Guiana Shield. In 2024, 560,000-hectares (1.38-million-acres) of the area where the record-breaking giant and other giant trees have been found, has been upgraded to the "full protection" or State Park category. The newly created conservation area has been called the
Giant Trees of the Amazon State Park. This means that activities like logging, permitted under the "sustainable use" category when it was previously part of Paru State Park, can no longer be proposed in its bounds. Although the area is still completely preserved, and no logging has been documented thus far in the new conservation area, the move will future-proof the area against potential threats. Scientific research and ecotourism will be allowed in the
Giant Trees of the Amazon State Park, which would also generate revenue. ==See also==
