ZUSAMMENFASSUNG:
Ableitungen möglich
Regional differenziert
Bewertung:
Mäßig-schlecht
Innere Typen: schlecht
Für Chlorophyll: mäßig in Ästuaren wegen Lichtlimitierung und Salzgradienten
Ursachen:
Hohe N- und P-Einträge
System-Empfindlichkeiten
(Schichtung Aufenthaltsdauer, Nachbarschaft, Anreicherung)
Bewertungs - Möglichkeiten:
