Conclusions

• Before building of dams in the drained part of
  Cenas Mire the groundwater level was about 15.1
  cm or 2.8 times lower than in the intact area
• After building of dams the raise of the
  groundwater level is observed and the difference
  has decresed until 1.5 cm or is almost at the
  same level as in the intact part
• The difference between the intact and drained
  parts has decreased 6 times but in winter even 9
  times

31
Conclusions

• The habitat monitoring results show a great
  difference in the coverage and species number of
  vascular plants and bryophytes in the intact and
  drained areas
• The hydrological studies reveal that after the
  managaement actions was carried out, fast changes
  have taken place in the site hydrological regime
