These resources are also the basis for large-scale wood production in planted forests to satisfy the worldwide need for timber and paper.
Genetic resources of several important timber, fruit and other non-timber tree species are conserved ex situ in genebanks or maintained in field collections.
Nevertheless, in situ conservation in forests and on farms is in the case of most tree species the most important measure to protect their genetic resources.
[citation needed] In 2014, the Food and Agriculture Organization of the United Nations published the first State of the World's Forest Genetic Resources.
[9] Though forest trees are known for showing great plasticity in their response to climate changes,[10] not all species are naturally capable to adapt at the pace necessary.
