The genetic codes of living organisms are natural resources no less than soil, air, and water. Genetic resources-from nucleotide sequences in DNA to selected genotypes, populations, and species-are the raw material in forestry: for breeders, for the forest manager who produces an economic crop, for society that reaps the environmental benefits provided by forests, and the continued evolution of the species itself.
