B. MAYER: OPSEG I ZNAČENJE MONITORINGA PODZEMNIH I POVRŠINSKIH VODA ... SUMMARY: During the last quarter of the century the forest ecosystems in the Republic of Croatia have been exposed to increasingly aggressive anthropogenic effects and series of dry years. Especially large changes have occurred in the ground and surface water regimes in the lowlands forests of the northern Croatia following the construction of large flood control systems with flood storages and hydropower plants with reservoirs. The priority problem is drying out of the forest basins through reduction in floods and lowering of the groundwater tables, and decrease in quality of water which, in conjunction with the periods of drought, leads to deterioration of vitality of forest ecosystems, change in succession of forest sites from humid to dry, spreading of the phenomenon of drying out of trees or parts of forest management units. In order to successfully solve the increasing forest ecology and forest management issue, a network of hydro-pedological piezometer stations has been set during the last fifteen odd years. Organized monitoring of ground and surface water has so far encompassed several large forest basins, and further expansion is planned. A large database has been collected. The tools of the Geographical Information System (CIS) are increasingly ysed in organization, handling and interpretation of these data. The obtained results are the background of the decision-making in forest management and else. New hydro-pedological forest ecology mapping of degraded areas with changed water regime is conducted. The ingress of pollutants with contaminated flood waters into the forest soil is monitored. Key words : lowlands forests, ground and surface water monitoring Šumarski lisl br. 11 — 12.
