THE MAIN PROJECT RESULTS ACCORDING TO CHRONOLOGICAL ORDER:

Photojournal of the project activities:

April 2009 - Inception project seminar in Marijampolė municipality
April 2009 - Planning of hydrology restoration works in Amalva bog
May 2009 - Experience exchange and network building visit to LIFE project site - Dummer area (Germany)
August 2009 - beginning of the reconstruction works of the Žuvintas sluice-regulator
October 2009 - concrete pouring of the permanent spillway instead of former sluice-gates
November 2009 - preparation for building of fish-ladder by the spillway
January 2010 - clearcut on the Amalva bog where blocking of the drainage ditches is planned
March 2010 - after the clearcut the southern part of the Amalva raised bog is again open as it was before digging of the drainage channels.
March 2010 - Channels are filled with branches what should reduce wind forced water undulation and support establishment of sphagnum.
April 2010 - improvement of 2,2 km of Žuvintas wetland protective dike is under finalization.
April 2010 - improvement of Žuvintas wetland protective dike - plastic piling used in the most sensitive places to prevent water seepage and subsequent erosion of the dike.
April 2010 - Leveling of the Amalvas protective dike. In some places the dike completely subsided and just absence of trees makes it distinguishable from the surrounding area.

11th of June 2010 - a Žuvintas Lake sluice regulator  reconstructed into permanent spillway dam was oppened. This ended the 40 years period of regulation of water level that negatively affected the whole Žuvintas wetland.
June 2010 - improved Žuvintas wetland protective dike. It sustains water in Žuvintas wetland and prevents flooding of nearby fields used for agriculture. It's visable significantly higher water level on the left side of the dike.
June 2010 - meeting in Amalvas polder by subcontracted specialists from Lithuanian agrarian istitute, Marijampolė municipality administration, Žuvintas biosphere reserve and Nature Heritage Fund - a starting point for preparation of guidelines for sustainable peatland grassland use.
July 2010 - rising of the road through the Amalvas wetland in order to avoid flooding of it after blocking of drainage channels.
July 2010 - 2 additional sections (~300 m each) of the Žuvintas protective dike were improved. As it can be seen from the picture, the dike perfectly sustains water.
September 2010 - drainage ditches are blocked in ~100 ha of previously clearcut Amalvas wetland area. A plastic piling dam is covered with branches. It perfectly sustains water in the ditches.
September 2010 - reconstruction of Amalvas sluice-gate and protective dike has started.
September 2010 - reconstruction of Amalvas polder is being discussed by Žuvintas reserve directorate representatives, experts in agriculture and hydrology.
November 2010 - standing water pools in the southern part of the Amalvas wetland indicate that water restoration measures are working,
November 2010 - reconstruction of the Amalvas wetland protective dike is progressing even in difficult high water conditions. New section of the dike is being built to restore water level in ~50 ha of former wetland.
December 2010 - finished reconstruction of Amalvas sluice-gate into spillway ensuring natural water fluctuation and fish migration.
February 2011 - using the opportunity provided by cold February weather plastic pilling sheets for blocking of the drainage channels were transported to the Žuvintas bog.
March 2011 - Freezing weather enabled easier instalation of the plastic pilling dikes on approximately 5 km long drainage ditches in the Žuvinta bog.
March 2011 - Sustainable peat grassland management guidelines were  printed for distribution to local farmers and regional authorities. Guidelines aim at raising awareness on damaging impacts of intensive farming on peatlands and promotion of sustainable farming practices.
April 2011 - Forest clearcutting is completed in the whole area (210 ha) where restoration of water level is going to take place.
May 2011 - Local farmers were introduced to Amalvas polder reconstruction project and Sustainable peat grassland management guidelines.
July 2011 - Plastic pilling poles used for blocking drainage channels in ~107 ha of Amalva bog.
July 2011 - 30 ha of Amalvas polder meadows were fenced and a starting herd of 16 cattle of hereford breed was purchased for meadow management. A contract was signed with a local farmer regarding handling of the meadow and the cattle.
September 2011 - Inspection of efectiveness of the plastic pilling dams built on the drainage ditches of the Žuvintas bog revealed success in raising water table to the ground surface level.
September 2011 - Due to unexpected sinking of a section of reconstructed Amalva wetland protective dike, plastic pilling poles were used to sustain water. (Plastic pilling section visible in the picture was later covered with fen peat)
November 2011  - reconstruciton of Amalvas polder pumping station. Resonstruction will result in spring flooding and higher whole year ground water levels in the polder area (638 ha). High water table will still make  grassland management (grazing and mowing) possible, but will reduce peat degradation, improve conditions for meadow birds and reduce exploatation costs of the pumping station. 
December 2011 - Blocking of the portion of the Amalvas polder channel neighbouring the very Amalva bog resulted in substantially elevated water levels and elimination of draining effect.
March 23 - The final project event took place in Žuvintas Visitor Centre. Key stakeholders and policy makers took part in the event and discussed project results. Premiere of the film "Revival of wetlands" (Author Eugenijus Drobelis) helped the audience to perceive better the beauty of nature of the Žuvintas biosphere reserve and learn more about the actions carried out by the project.
