The black and the white rhinoceros have become flagship species for international conservation. They are significant not only for the continuation of a major evolutionary heritage, but also as symbols for the protection of African savannahs. The battle for the survival of these species has been marked by some notable successes and sadly, many failures, and the situation is still critical.
Conifers are one of the world's most important resources of timber. If managed wisely and used sustainably, these resources will provide wood for a multitude of purposes, virtually indefinitely. Additional products include resins and their derivatives, and even medicinal extracts, for example taxol now used in the treatment of cancer. Conifers occur on all continents except Antarctica.
