Key messages

• Having effective tree seed and seedling delivery systems is key for enabling tree growers to plant trees to provide needed products and services.
• The situation of tree seed and seedling supply in most places is currently inadequate, however, with growers often using planting material of unknown history and poor performance.
• To make improvements, conducting a sectoral assessment of the current situation is the starting point. How to do this is explained in this brief, and we outline steps that build on the assessment.
