Timber plants are often medium to large trees that have been felled for the purpose of extracting the wood. This material will be used for a variety of purposes, such as construction, paper, and so on. Timber trees come in three varieties: soft, semi-hard, and hardwood. Today, more over 100,000 timber species with wood in their trunks and branches are known; however, only 500 of these species are expected to be commercially viable. Furthermore, the majority of the wood harvested from these trees is used in countries other than the ones where it was grown. The Flora and Fauna International Trade Code oversees this, which includes timber species suitable for commercialization and export.
