Abstract
The groundwater level lowering or raising is the key task of water amelioration systems, which covered almost the entire territory of Rivne region. Adjusting the groundwater level is the most important factor influencing forest health conditions. In turn, the level of groundwater is the most important factor that affects the state of forest stands located on reclaimed area. However, the general trends of the water amelioration systems influence on the state of forest stands are not defined. Many studies conducted at different times suggest both a positive and negative impact of amelioration on growth and state of forest stands. The authors examined correlation between fluctuations in groundwater level in amelioration systems of the region and state of forest stands under their influence. It was found that the dominant factor for the forest stands in Polissya area is seasonal amplitude of fluctuations of groundwater levels – the higher it is, the more the area of problematic stands. Increasing of the amplitude of seasonal fluctuations in groundwater affects differently the state of forest stands in forest-steppe zone. In some forestry their condition worsens, in others the opposite tendency to improve their condition is noted.
