Vegetation and hydrology monitoring is continued
 
 
Since the end of the project Nature Conservation agency has continued collecting information on ground water levels on regular basis. In order to ensure that the restoration of Bog woodland habitat was succesfull and the hydrological regime in the Gulbjusala bog will eventualy return to its natural state the ground level vegetation montiong also must be continued. So in year 2017 during the growing season we will perform a full vegetation monitoring in the previosly set sample spots.

In total 37 ditches with a total length of 13,954 m and area of 138 hectares were affected in the Gulbju sala bog. 29 ditch sections were fully filled with peat. Filling up the drainage ditches is considered to be a more effective approach than dam building and this approach was used in all areas where it was practically possible – enough peat left on the ditch sides. On three ditches four peat dams were built. On five ditches 29 wooden sheet pilings were built. Mostly all hydrology restoration works were done by tractors. In places, where it was not possible for tractors to reach the ditches, dams were built by hand. The dams were built using the wood that is growing near by the ditch.
