The work of the CGIAR Research Program on Forests, Trees and Agroforestry (FTA) on tree seed systems — the authors’ shorthand for the means through which growers obtain access to tree-planting materials, either seeds or seedlings — has sought to address significant constraints in the diversity and genetic quality of the tree seeds and seedlings that are being supplied. These concerns are exacerbated by an increase in demand for germplasm to meet huge global forest landscape restoration commitments and other tree-planting targets. Over the last decade, FTA has worked on twin concerns in this regard: first, how to make available quality tree-planting material; and second, how to ensure that tree seeds and seedlings are planted in the right places for the right purposes. It has addressed availability through building stakeholder partnerships and model tree seed systems; delivering improved “orphan” (under-researched) tree crops through supporting breeding and its impact; mainstreaming food trees through nurseries; conserving and making available diverse tree germplasm to support delivery and use; and developing policies to support the effective supply of tree seeds and seedlings. It has supported better decision making through building information platforms to support tree-planting choices and tree seed system operations; designing maps to guide tree seed and seedling distribution that is suited to current and predicted future climatic conditions; and releasing statistical packa...
