Vegetation and flow regime in lowland streams
Tenna Riis1*, Alastair M. Suren2, Bente Clausen3**, Kaj Sand-Jensen4
Appendix S1. Aquatic plant species found at 44 stream sites in Denmark. Relative
frequency is the percentage of the 44 sites at which the species was present. Disturbance
tolerance scores describe low (0) to high (6) disturbance tolerance of a species based on
information on five traits derived from Willby et al. (2000). Numbers in italics are based
on own observation and not included in Willby et al (2000), and indicate that these reed
plants use the bank as a refugium from which they can spread back into the stream bed
after a disturbance
