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.

Visitors to parks and protected areas impact at many levels: political, economic, social and ecological. To ensure effective park management for increasing visitor numbers, good quality global data on visitor use is necessary. This manual describes terms, approaches and techniques for gathering information about public use of parks and protected areas.
