Stoutest Tree

The aberrations of past measurements of yews are beyond belief. For example, the tree at Tisbury has a well-defined, clean, if irregular bole at least 1.5 m long. It has been found to have a girth that dilated and shrunk in the following way: 11.28 m (1834 Loudon), 9.3 m (1892 Lowe), 10.67 m (1903 Elwes and Henry), 9.0 m (1924 E. Swanton), 9.45 m (1959 Mitchell) … Earlier measurements have therefore been omitted. As a general standard, tree girth is taken at “breast height”.

This is cited as dbh (diameter at breast height) in tree and forestry literature.Breast height is defined differently in different situations, with most forestry measurements taking girth at 1.3 m above ground,while those who measure ornamental trees usually measure at 1.5 m above ground; in most cases this makes little difference to the measured girth. On sloping ground, the “above ground” reference point is usually taken as the highest point on the ground touching the trunk Some of the inflated old measurements may have been taken at ground level.

he stoutest living single-trunk species in diameter are: 1. Montezuma Cypress Taxodium mucronatum: 11.62 m (38.1 ft), Árbol del Tule, Santa Maria del Tule, Oaxaca, Mexico.Note though that this diameter includes buttressing; the actual idealised diameter of the area of its wood is 9.38 m (30.8 ft). 2. Giant Sequoia Sequoiadendron giganteum: 8.85 m (29.0 ft), General Grant tree, General Grant Grove, California, United States 3. Coast Redwood Sequoia sempervirens: 7.9 m (26 ft), Lost Monarch Jedediah Smith Redwoods State Park, California, United States. 4. Australian Oak Eucalyptus obliqua: 6.72 m (22.0 ft) 5. Australian Mountain-ash Eucalyptus regnans: 6.52 m (21.4 ft), Big Foot 6. Western Redcedar Thuja plicata: 5.99 m (19.7 ft), Kalaloch Cedar, Olympic National Park 7. Sitka Spruce Picea sitchensis: 5.39 m (17.7 ft), Quinalt Lake Spruce, Olympic National Park 8. Kauri Agathis australis (Te Matua Ngahere): 5.33 m (17.5 ft).[23] 9. Alerce Fitzroya cupressoides: 5.0 m (16.4 ft) An additional problem lies in instances where multiple trunks (whether from an individual tree or multiple trees) grow together.
