By National Research Council, Board on Agriculture, Committee on Managing Global Genetic Resources: Agricultural Imperatives

Information experiences referring to decline of the world's forests have gotten unfortunately conventional. such a lot losses are measured in sq. kilometers, yet a extra profound loss can't be measured. As forests disappear, so do their genetic assets. The genes they own can now not relief of their version to a altering surroundings, nor can they be used to increase more desirable forms or items. This e-book assesses the prestige of the world's tree genetic assets and administration efforts. options for assembly destiny wishes and choices to harvesting usual forests are awarded. The booklet additionally outlines equipment and applied sciences for administration, evaluates actions now lower than method, and makes particular techniques for a world method for woodland administration.

Example text

The precise, future global needs for forest genetic resources are not possible to predict, but the widest possible genetic base should be maintained to provide the best array of future options. The programs of national and regional institutions to conserve, describe, document, improve, and distribute forest genetic resources are critical activities, and they urgently need to become more active and more effective. Techniques for establishing priorities must be developed. The particular requirements and challenges of countries and regions may vary, but the overall goal is to conserve and maintain a broad range of forest tree genetic resources for current and future use and as a foundation for conserving the world's biological diversity.

Html WORLD FORESTS 30 situ conservation preserves both the population and the evolutionary processes that enable the population to adapt. Ex situ conservation preserves the genetic diversity extant in the population in a manner that makes samples of the preserved material readily available. In situ conservation takes place on the site where the trees or their immediate parents are growing naturally. Thus, maintenance of a mature natural forest in a state undisturbed by managerial or other human intervention is conservation in situ, provided the trees are capable of reproducing.
