General National Id Latvia_03 Site name Located in L127 and L161 (water bodies codes according to the Lielupe river basin management plan). Located in the nature reserve, Natura 2000 (in Daudzese parish, Jaunjelgava County). Summary The main goal of the implemented NWRM was to restore natural hydrological regime in drained raised bog Aklais located in nature reserve area being also the Natura 2000 site in Latvia. Building of the dam was chosen as most appropriate method. Due to natural conditions, there was no possibility to use technique thus dams were built by hand. Unfortunately the part of the dams is partly washed out by waters now and in a result raised bog is not restored as expected. The main lesson for future is to use adequate technique and materials to ensure durability of the dams. Light or indepth?

Key lessons The main goal of the implemented NWRM was to restore natural hydrological regime in the drained raised bog located in nature reserve and included in Natura 2000 site. Building of a dam was chosen as most appropriate method to stop artificial drainage. Due to natural conditions, there was no possibility to use technique and heavy machinery, therefore dams were built by hand. Unfortunately a part of the dams is destroyed by waters now and in a result raised bog is not restored as expected. The main lesson for future is to use proper technology for constructing a safer dam.

However, typical raised bog species like bog-moss Sphagnum cuspidatum and cotton-grass Eriophorum vaginatum have begun to dominate percentage cover while the cover of heather Calluna vulgaris has begun to decrease.
