It is an evergreen tree or large shrub growing to 10–18 m tall, with a trunk up to 60 cm diameter. The leaves are lanceolate, flat, dark green, 1–3 cm long and 2–3 mm broad, arranged spirally on the stem, but with the leaf bases twisted to align the leaves in two flattish rows either side of the stem except on erect leading shoots where the spiral arrangement is more obvious.
Grazing animals, particularly cattle and horses, are also sometimes found dead near yew trees after eating the leaves, though deer are able to break down the poisons and will eat yew foliage freely. In the wild, deer browsing of yews is often so extensive that wild yew trees are commonly restricted to cliffs and other steep slopes inaccessible ...
Yew poisonings are relatively common in both domestic and wild animals which consume the plant accidentally, [8] [9] [10] resulting in "countless fatalities in livestock". [35] Taxines are also absorbed efficiently via the skin. Taxus species should thus be handled with care and preferably with gloves. [7]
The Iwokrama Forest is a 3,716 square kilometres (1,435 sq mi) nature reserve of central Guyana located in the heart of the Guiana Shield, [2] one of the four last pristine tropical forests in the world (Congo, New Guinea, and the Amazon rainforest are the others). [3]
Taxus canadensis, the Canada yew [2] or Canadian yew, is a conifer native to central and eastern North America, thriving in swampy woods, ravines, riverbanks and on lake shores. Locally called simply as "yew", this species is also referred to as American yew or ground-hemlock. Most of its range is well north of the Ohio River.
Recommending the name "mountain yew" for British use, Nelson was unaware that this Florida species grows almost at sea level — and thus nowhere near any mountains [6] Of all species of its genus, Florida torreya is the only one whose historically native habitat is not in mountainous terrain.

A cutting of the Fortingall Yew at Kindrogan Field Studies Centre Clippings from the tree have been taken to the Royal Botanic Gardens, Edinburgh, to form part of a mile-long hedge. The purpose of this "Yew Conservation Hedge Project" is to maintain the DNA of Taxus baccata from ancient specimens in the UK as, worldwide, the trees are ...
Slash-and-burn agriculture is a farming method that involves the cutting and burning of plants in a forest or woodland to create a field called a swidden. The method begins by cutting down the trees and woody plants in an area. The downed vegetation, or "slash", is then left to dry, usually right before the rainiest part of the year.
