Sources of forest reproductive material
The use of sound seed from stands of high inherent quality is widely recognised as the best means of ensuring fast-growing and healthy plantations capable of yielding good quality wood. All of the basic material we collect is under the three categories: selected material, where the basic material has undergone phenotypic selection at the population level, qualified material, where there has been phenotypic selection at the individual level, tested material for fast growing tree production. Some seeds are source identified material.
