The OECD Scheme for the Control of Forest Reproductive Material Moving in International Trade is open to OECD Members as well as to other States. To date 25 participating countries implement the Scheme (including tropical countries which are developing their seed exchange for reforestation purposes). Seeds and plants are produced and officially controlled according to common harmonised procedures.
The OECD Forest Seed and Plant Scheme defines three broad categories of forest reproductive material recognised for certification: Source-identified material (minimum standard); Material from selected stands located in well-delimited regions of provenance; Material from untested seed orchards which can produce seed of improved quality.
Different OECD labels are used according to the category of the forest reproductive material. The labelled material is then recognised internationally as "QUALITY GUARANTEED" and "OF CONTROLLED ORIGIN". All categories included, the participating countries approved to date 275 tree species eligible for OECD certification of reproductive material, with a total area of 13.6 millions of hectares.
AN UPDATE OF THE RULES became necessary in recent years because of a growing commercial importance of new types of material derived from breeding programmes. A complete revision of the Scheme has been undertaken by participating countries to keep in line with new forestry production and tree improvement techniques.
