Abstract

The influence of habitat conditions on macrophyte growth dynamics was monitored during 2007, 2008 and 2009 on 75 sites in watercourses of three regions in lowland Croatia: Baranja, Lonjsko polje and Bosut River Basin. The areas with higher species richness and elevated nutrient conditions were indicated according to species composition and habitat conditions. In catchments with highly agricultural land use with shallow, maintained watercourses and anthropogenic disturbance development of amphibious and terrestrial species were recorded. The spread of free-floating species were associated with higher urban land use and higher nutrient concentrations. Submerged aquatic vegetation was found in deeper watercourses with the higher transparency. Amphibious and terrestrial macrophytes have been dominated during drought conditions and free-floating species during rainy periods of high water. Seasonal changes of dominate species were controlled by nutrient enrichment, competitive advantages and other habitat conditions.
