WP2 focuses on hydromorphological and ecological processes and interactions within river systems with a particular emphasis on naturally functioning systems. D2.1 proposes a hierarchical framework to support river managers in exploring the causes of river management problems and devising sustainable solutions. D2.2 builds on this framework by exploring published research and available data sets to more formally encompass the biota. This report (Part 1 of Deliverable 2.2) is concerned with riparian and aquatic vegetation. It encompasses the following sections: natural vegetation and hydromorphological of European rivers; a conceptual model of vegetation-hydromorphology interactions; application of the conceptual model to European rivers.

WP2 focuses on hydromorphological and ecological processes and interactions within naturally functioning river systems. D2.1 proposes a hierarchical framework to support river managers in exploring the causes of river management problems and devising sustainable solutions. D2.2 builds on this framework by exploring published research and available data sets to more formally encompass the biota. This report (Part 2 of Deliverable 2.2) considers interactions between hydromorphology and macroinvertebrates and fish, and the role of floods and droughts as biota-shaping phenomena. Lastly, part 2 presents conclusions from the whole of Deliverable 2.2.
