1. Species selection
Plant tree species that are typical of the reference forest, which also catalyse natural forest regeneration by rapidly suppressing weed growth and by attracting seed-dispersing animals. Match species with your site conditions, in terms of altitude, rainfall etc. Coming soon, we will have a simple species-selection tool to help you decide which species to propagate and plant for the forest type you are restoring and your site conditions. In the mean time, please browse "Tree Seeds and Seedlings" and Chapter 9 of "How to Plant a Forest".
3. Seed Supply - from the Doi Suthep Nature Study Centre Seed Bank
At CMU's Doi Suthep Nature Study Centre we have a seed bank dedicated to storing native forest tree species. 
Contact Us to deposit seeds in the bank.
4. Seedling Identification Tool
The ability to recognize the species of tree seedlings and sapling is essential for forest ecosystem restoration for several reasons:
- Trees in nurseries are often mislabelled or not labelled at all. When collecting planting stock from a nursery, always double check the species' identity, to ensure that the right species are planted in the right places.
- During a rapid site assessment, species names of trees found in the sample units should be recorded - from saplings 50 cm tall upwards. Thus, biodiversity can be increased by planting trees of species that are not already present.
- Monitoring restoration progress. Forest ecosystem restoration involves encouraging species recruitment. A recruit species is a tree establishing naturally within the restoration site, which does not belong to any of the species that were planted. Recruit species usually arrive as seeds carried on the wind or by animals. So, recording the species of tree seedlings and saplings establishing beneath the restored forest canopy, from incoming seeds, is an important component of monitoring biodiversity recovery.
