The Darling 58 is a genetically engineered American chestnut tree. The tree was created by American Chestnut Research & Restoration Program (ACRRP) at the State University of New York College of Environmental Science and Forestry (SUNY ESF) in collaboration with The American Chestnut Foundation (TACF) [1] to restore the American chestnut to the ...
Thus, the newly bred hybrid chestnut trees should reach the same heights as the original American chestnut. Many of these 15/16 American chestnut hybrids have been planted along the East Coast, including in the Jefferson National Forest and on the Flight 93 National Memorial. Some of these sites have had researchers check on the saplings that ...
Young tree in natural habitat American chestnut male (pollen) catkins. Castanea dentata is a rapidly-growing, large, deciduous hardwood eudicot tree. [20] A singular specimen manifest in Maine has attained a height of 115 feet (35 m) [21] Pre-blight sources give a maximum height of 100 feet (30 m) and a maximum circumference of 13 feet (4.0 m).

The American chestnut tree was nearly wiped out by disease. But efforts are underway to develop a new strain that's more resistant to blight. A Stroll Through the Garden: Efforts underway to ...

Leaf and flower detail of a Chinese chestnut at New York Botanical Garden. It is a deciduous tree growing to 20 metres (66 ft) tall with a broad crown. The leaves are alternate, simple, 10–22 centimetres (4– 8 + 1 ⁄ 2 in) long and 4.5–8 cm (1 + 3 ⁄ 4 – 3 + 1 ⁄ 4 in) broad, with a toothed margin.
The American chestnut, virtually eliminated from eastern forests, survived in small isolated pockets. Some survivors have been cross-bred with the blight-resistant Chinese chestnut and introduced into National Forests in trial studies. [11] Parasitoid wasps have been approved for release by the USDA to combat the emerald ash borer. Pesticide ...
The mission of The American Chestnut Foundation (TACF) is to restore the American chestnut tree to the forests of Eastern North America by breeding genetically diverse blight-resistant trees, evaluating various approaches to the management of chestnut pests and pathogens, and reintroducing the trees into the forest in an ecologically acceptable manner.
