Considerations Regarding Alpine Rivers And Their Ligneous Vegetation With Myricaria germanica In The Maramureş Mountains Nature Park (Romania)

The habitat 3230 Mountain rivers and their ligneous vegetation with Myricaria germanica was not listed in the standard form based on which the Natura 2000 site ROSCI0124 Maramureș Mountains was declared. The aim of this study is to offer some new information regarding the structure, distribution and ecology of the Natura 2000 habitat 3230 Mountain rivers and their ligneous vegetation with Myricaria germanica in Maramureș Mountains Nature Park. The ecological importance of habitat 3230 results from the capacity of Myricaria germanica to colonize new deposits of gravels and set up new biocoenoses, this ability being possible only in the case of natural morphodynamics of the mountain streams, not influenced by human activities.
