Oecesis of white willow commuties in the nature reserve Věstonická nádrž reservoir

Original language description

The construction of Nové Mlýny water reservoir has caused the break of floodplain corridors connectivity between alluviums of Dyje, Svratka and Morava rivers. The Czech Ministry of Environment adopted the ecologisation policy of Nové Mlýny middle water reservoir after 1989. Within this policy the water level was lowered by 85 cm in July of the 1996 (to the spot height 169.5 m a.s.l.). Two artificial islands were built up to perform as a part of regional biological corridor running through middle water reservoir. After the lowering of water surface level in the reservoir 70 ha of banks arised and in the Jihlava and Svratka rivers confluence in process of intensive sedimentation formed a new island. The viable seeds of anemochorous willow and poplar trees could not show up in the air in July, at the time of water surface level lowering, because a rain of seeds is present only in May and June. Nevertheless in September the depositions without vegetation were covered by the white willow an
