Question

what are the causes and depletion of Himalayan yew plant

Answer 1

English yew, (Taxus baccata), also called common yew or European yew, (all three are lumbertrade names), an ornamental evergreen treeor shrub of the yew family (Taxaceae), widely distributed throughout Europe and Asia as far east as the Himalayas. Some botanists consider the Himalayan form to be a separate species, called Himalayan yew (Taxus Wallachia's). Rising to a height of 10 to 30 metres (about 35 to 100 feet), the tree has spreading branches and slightly drooping branchlets. The bark is reddish brown and flaky, sometimes deeply fissured in very old trees. Yews are among the few conifers that produce new growth easily from behind the ends of cut branches; thus, English yew is one of the only conifers regularly trimmed into hedges. All parts of an English yew, except the fleshy arilsurrounding the seed, contain alkaloids that are poisonous to humans and several other animals. After swallowing the seed whole, thrushes and other birdsare known to digest the aril and pass the seed intact in their droppings.
