No_PlantID	-	All culms of the target species counted. The total number of culms are defined as the total number of plant individuals.	-	0.25x0.25 field plot mapping	-
No_LivingLeaves	-	10 individuals (if available) of the target species were selected, stored in separate bags and brought to the laboratory on the same day. All living leaves of the selected individuals were counted. Leaves were classified as living if at least 50 % of one leaf was green and present. If more than 50 % were devoured by herbivores it was classified as dead.	literature	0.25x0.25 field plot mapping	Daoust, R. J. & D. L. Childers (1998) Quantifying aboveground biomass and estimating net aboveground primary production for wetland macrophytes using a non-destructive phenometric technique. Aquatic Botany 62(2):115-133 doi:10.1016/S0304-3770(98)00078-3.
No_DeadLeaves	-	10 individuals (if available) of the target species were selected, stored in separate bags and brought to the laboratory on the same day. All dead leaves of the selected individuals were counted. Leaves were classified as dead if one leaf was less than 50 % green or not present. If more then 50 % were devoured by herbivores it was classified as dead.	literature	0.25x0.25 field plot mapping	see above
LeafLength	cm	10 individuals (if available) of the target species were selected, stored in separate bags and brought to the laboratory on the same day. Length of the leaves was measured in the laboratory with centimeter precision by flattening the probes on graph paper. In C. riparia and P. arundinacea, leaf length was defined as the distance from leaf sheath to tip, and for R. amphibia and P. amphibia, only the leaf blade was considered	literature	0.25x0.25 field plot mapping	see above
LeafWidth	cm	10 individuals (if available) of the target species were selected, stored in separate bags and brought to the laboratory on the same day. Width of the leaves was measured in the laboratory with centimeter precision at half of the leaf length by folding flattened probes in half on graph paper.	literature	0.25x0.25 field plot mapping	see above
CulmDiameter	cm	10 individuals (if available) of the target species were selected, stored in separate bags and brought to the laboratory on the same day. Culm diameter was measured in the laboratory with centimeter precision. To avoid inaccuracy in culm diameters, the arithmetic mean of two measurements were used for P. arundinacea, R. amphibia and P. amphibia. For C. riparia, culm diameter was measured only once at the ground leaf rosette in the field before the harvest.	literature	0.25x0.25 field plot mapping	see above
TotalHeight	cm	10 individuals (if available) of the target species were selected, stored in separate bags and brought to the laboratory on the same day. Plant height was measured in the laboratory with centimeter precision by flattening the probes on graph paper. Total plant height corresponds to the distance between the cutting point and tip of the tallest leaf.	literature	0.25x0.25 field plot mapping	see above
DM	g	All plant individuals of the target species were harvested from the plot area confined by a wooden frame. Only individuals inside the frame considered, whereas individuals rooting outside the frame were separated manually before clipping. On the same day, the biomass was dried at 60°C for 48 h in drying chambers. Then, the dry mass was weighed to the nearest 0.01 g with a laboratory scale.	drying oven (Rumed Rubarth Apparate GmbH and memmert GmbH & Co.KG) and scales (Kern EMB 200-2)	biomass determination	-
