With the co-funding from the Global Environment Facility, 22,397 ha of degraded peatlands were restored between 2009 and 2011. Restoration at these 10 sites helped stop annual emission of about 448,000 tons of CO2 from peatland fires and mineralization, and saving the country tens of millions of dollars in fire-fighting operations. Already one year after rehabilitation most sites showed re-emergence of typical wetland vegetation (primarily Sedge communities) and its domination over trees and shrubs (pictures attached). The density of water-birds increased by 12-16%. At the re-created wetlands scientists recorded the IUCN-listed Aquatic Warbler (VU), Greater spotted eagle (VU), Black-tailed godwit (NT), as well as other wetland species previously lost from these areas, such as Common snipe, Reed bunting, Lapwing, Sedge warbler, Great reed warbler. Restoration cost (from engineering design to having water level restored) has been around US$50/ha. Restoration mostly involved use of local materials and local labor. Since 2011, restoration of peatlands at other sites continued without external donor support.

Enabling factors

- adoption and acceptance of technical standards mentioned in the previous building block is important for success of restoration on the ground.

Lessons learned

- rewetting peatlands through closing of the drainage canals and ditches is a natural solution which is the only effective way of addressing peat fires. The water does return even if it seems that it has gone completely from the peatland.
