I want to know the answer to the following question:
How many species of plants have been identified in the Alpine regions?
All the background I'm provided with is that "These do not reach exactly to the same elevation, nor are they often found growing together; but their upper limit corresponds accurately enough to the change from a temperate to a colder climate that is further proved by a change in the presence of wild herbaceous vegetation.". Is that enough to answer the question?
Answer: no
