Abstract
AbstractThe target of the Indonesian government was to restore at least 2 million ha of degraded peatlands by 2020. This can be achieved by applying three approaches: rewetting, revegetation, and revitalization of the community. In revegetation, the use of native tree species is recommended in the technical guidelines for peatland restoration. The interest in using native plant species for ecosystem restoration, particularly for peatland restoration, is increasing significantly. The native species may adapt well to the environment and usually correspond with the people’s preference. An important concern in revegetation is the selection of suitable genetics of the planting stocks. In peatland restoration, a seed source with high genetic diversity should be used since it maintains the genetic entity. On the other hand, low genetic diversity used for peatland restoration may result in the genetic drift of the populations. A native tree species, Dyera polyphylla (locally known as jelutung), has been widely used for peatland restoration in Indonesia. Many other species can also be developed and require further research. Several community-based seedling nurseries have been established in Sumatra and Kalimantan. The challenge is to emphasize the importance of genetic diversity to the farmers with businesses in a seedling nursery. The necessary strategy of seed sourcing in peatland restoration includes composite provenancing and admixture provenancing.
