Abstract
Paper presents results of investigation of hydrological conditions and nutrients limitation and availability for wetland vegetation in selected sites within Biebrza river valley. Analyse d sites were overgrown by tall sedge Magnocaricion vegetation (Caricetum gracilis and Caricetum elatae), wet meadow Molinio - Arrhenatheretea vegetation (Molinietum caeruleae), and sed ge - moss Scheuchzerio - Caricetea nigrae vegetation (Caricetum lasi ocarpae). There were noted a close re lationship between vegetation types, hydrological regimes and kind of nutrient limitation. Low productive Molinio - Arrhenatheretea and Scheuchzerio - Caricetea nigrae vegeta tions fed mainly by groundwater were limited by phosphorus, while highly productive Magnocaricion vegetation, fed by river water, was subjected to nitrogen limitation. We have found big diversi fi cation of groundwater and surface water levels within habitats o f different vegetation types along the Biebrza river valley. Magnocaricion vegetation present on fl ooded areas is characterized by signi fi cant water level fl uctuations and long - lasting inundations. On areas covered by Molinio - Arrhenatheretea vegetati on we noted majority of water levels not exceeding the level of the ground surface. Whereas Scheuchzerio - Caricetea nigrae vegetation, fed by groundwater, is characterized by low variation of groundwater levels .
