What level of protective plant is the yew?

Taxus, also known as Yew, Selaginella officinalis, Platycladus orientalis, Taxus chinensis, Guanyin Taxus, etc., is a yew tree of the Taxus family. Because of its slow growth rate and poor regeneration ability under natural conditions, for a long time, a large-scale yew raw material forest base has not been formed in the world, so let's take a look at how many grades of protective plants Taxus is.

What level of protective plant is the yew?

China's first-class rare and protected tree species. Taxus is recognized as a natural rare anticancer plant on the verge of extinction in the world.
