A seed source is a group of trees growing together from which one can collect seed for multiplication. This may be an identified number of trees in a landscape-farmland/natural forest or a group of trees from which you obtain seeds. A good seed source for trees should provide fast-growing healthy, genetically diverse planting material. Selecting good seed sources results in high-quality seeds and therefore superior end products. It is good to note that not every seed source will provide good quality seeds. The genetic quality of the seed source is the decisive factor for the success of any tree planting programme hence seed sources have to be carefully identified and selected. The selection of seed sources is based on the assumption that the characteristics of the seed trees are likely to be transmitted to their offspring. Farmers commonly plant trees on farms or community lands to grow products' that satisfy household needs and market demands. Tree seeds, a key input that determines the success of any tree planting activity, are often in short supply. Smallholders and NGOs collect or produce most of the seed used in their tree planting programs. Unfortunately, experience shows that smallholders and NGOs have limited knowledge concerning proper tree seed collection and handling procedures. As a result, most of the seed collected by smallholders and NGOs is of questionable genetic and physical quality.
