Reproductive processes in populations of broad-leaved woody species, inhabiting in afforested floodplain landscapes of European Russia

In two afforested floodplains of similar plain rivers, within state natural reserves in the both, demographic structure of broad-leaved woody populations was observed in forest, shrub and meadow communities. It was revealed, by comparing of regeneration density, that in forests (inundated for 1-4 weeks annually) recruitment of ash (in nemoral zone), elm and linden (in hemiboreal zone) are high numerous, but reproduction of oak populations is suppressed. Contrary, in both floodplains oak regeneration is numerous in meadows (of the same inundation longevity) about 10-12 years after mowing was ceased, whereas other broad-leaved woody species do not invade in these communities.
