The team of investigators

Ing. Richard Hrivnák, PhD.

Address:

Profile:

He is devoted to the study of vegetation of wetlands (springs, bogs, open water, marshes, wet meadows and marshes), phytocoenology and ecology, as well as the relationship between the distribution, abundance and diversity of macrophytes and environmental conditions. He is also interested in seasonal and annual growth of vegetation or selected species of higher plants. In addition, he is involved in the research of forest vegetation (alder, willow, beech and scree forests) and processes related to overgrowing of grasslands trees.
