In 2009: According to our plan, no activities have been implemented yet.

 

In 2010: According to our plans, no activities have been due yet.

 

In 2011: No activities have been done yet. The actions were due to start in 2010. The action is now expected to be implemented in the summer of 2012 due to the delay of the approval of the permitted plan. As soon as the final permit for the technical plan is given we will start the selection process to find the suitable contractor and the technical supervisor.

 

In 2012: By the end of June 2012 we had an approved permitted implementation plan by TIKÖFE and the field works of this action were finally started on the 20th of July in 2012. In map 1 there is a summary of the realized works in the Nagy-szik. One of the major works of the entire field work is to convert the unnatural deep channel of Magdolna-ér into an overflowing shallow watercourse. This was completed in 2012.
