Code Comment
099 Relies on periodic flooding to eliminate plants that compete for the same habitat *004*.
038 Seeds appear to be short lived, may be viable for only 2 years *005*.
046 Dispersal is chiefly by floodwater *06* which gives achenes potential for long distance dispersal *008*.
034 Species is eliminated by competition in three to five years without disturbance *008*.
042 Reproduces vegetatively by basal rosettes and sexually less often *008*.

Management

Beneficial Management Practices:

Water - develop/maintain wetlands
Water - control sedimentation
Water - develop/maintain mudflats
Water - other (specify in comments)
Agricultural - control erosion

Beneficial Management References: 004 , 005 , 008

Adverse Managment Practices:

Water - application of herbicides
Water - dredging and filling
Water - control water levels
Water - navigational improvements (channelization, dams, locks)
Water - drainage of wetlands, marshes, ponds, lakes
Water - other (specify in comments)

Adverse Management References: 003 , 004 , 005 , 002 , 008

Comments on Management:
Beneficial: is dependent on periodic disturbance from major floods, or from mowing and cultivation *06*. Succumbs to shading from competing species if not periodically disturbed *03*. Germination and seedling establishment does not occur where there is shaded soil after natural succession has been uninterrupted for 3-5 years *06*. Have been found in low-intensity agriculture sites *04*. May benefit from occasional farming, this eliminates competing plant species *04*. Adverse: major cause of decline is excessive siltation, which causes blockage and smothering of seed germination and seedling production *02,04,06*. Conversion (drainage)of wet prairies, natural lakes and marshes to row crops is detrimental *04*, as is destruction of floodplain habitat by construction of flood control levees *04.* Populations along roadsides are prone to being mowed during the growing season, preventing seed production *03*.
