Tree-planting is the process of planting tree seedling generally for forestation, reforestation, or ornamental purposes. Trees contribute to their environment over long periods of time by providing oxygen, improving air quality, climate amelioration, conserving water, preserving soil, and supporting wildlife. During the process of photosynthesis, trees take in carbon dioxide and produce the oxygen we breathe. Tree planting has become one of the international issues, because of it is the only solution to the world threat global warming and climate change. Seedling production is the basic requirement for launching tree planting and forest development. The quality of Seedlings is a major factor that determines the success of tree survival and reforestation programs. The survival of trees, growth, volume and quality of timber are greatly influenced by the quality of seedlings. The quality of seedling is defined by its genetic composition and physical characteristics. The quality of seedlings has a profound effect on the growth performance of planted trees. A low quality seedling is not worth planting because it will always produce a low quality tree, even if it is provided with the appropriate silvicultural treatments and planted in an appropriate site. Further, the plantation maintenance cost of low quality seedlings can be high due to high mortality and more intensive management requirement. By establishing and managing forest tree nursery, it is possible to produce seedlings. The objective of this manual is to provide information and guidance on how to establish and manage a forest tree nursery and on how to produce seedlings for different purposes. The manual is special interest to nursery workers, nursery supervisors, and foresters, those involved in planning and managing the production and use of forest tree seedlings for any of the above mentioned roles and benefits.
