There is a poem that everyone is familiar with, that is the famous line "Red beans grow in the south", but red beans are not widely distributed in our country. Everyone thinks that red beans are a symbol of longing, and may not know that yew is a precious tree. Moreover, the fruit of yew is a traditional Chinese medicine. Nowadays, yew has become a national protected plant because it is becoming less and less common. But what level of protected plant status is the yew? Yew, also known as yew, is a plant of the genus Taxus. It is a shallow-rooted plant with an unclear main root and well-developed lateral roots. It is recognized worldwide as an endangered natural rare anti-cancer plant. It is an ancient tree species left over from the Quaternary glaciers and has a history of 2.5 million years on Earth. Because yew grows slowly and has poor regeneration ability under natural conditions, a large-scale yew raw material forest base has not been formed in the world for a long time. In 1994, the yew was designated as a first-class rare and endangered protected plant in my country. It is also called a "national treasure" by the 42 countries around the world where yew trees are found. The United Nations has also issued a clear ban on its logging, making it a veritable "plant giant panda."
